How to check visibility of software keyboard in Android?

Question

I need to do a very simple thing - find out if the software keyboard is shown. Is this possible in Android?

NEW ANSWER added Jan 25th 2012

Since writing the below answer, someone clued me in to the existence of ViewTreeObserver and friends, APIs which have been lurking in the SDK since version 1.

Rather than requiring a custom Layout type, a much simpler solution is to give your activity's root view a known ID, say @+id/activityRoot, hook a GlobalLayoutListener into the ViewTreeObserver, and from there calculate the size diff between your activity's view root and the window size:

final View activityRootView = findViewById(R.id.activityRoot);
activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
    @Override
    public void onGlobalLayout() {
        int heightDiff = activityRootView.getRootView().getHeight() - activityRootView.getHeight();
        if (heightDiff > dpToPx(this, 200)) { // if more than 200 dp, it's probably a keyboard...
            // ... do something here
        }
     }
});

Using a utility such as:

public static float dpToPx(Context context, float valueInDp) {
    DisplayMetrics metrics = context.getResources().getDisplayMetrics();
    return TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, valueInDp, metrics);
}

Easy!

Note: Your application must set this flag in Android Manifest android:windowSoftInputMode="adjustResize" otherwise above solution will not work.

ORIGINAL ANSWER

Yes it's possible, but it's far harder than it ought to be.

If I need to care about when the keyboard appears and disappears (which is quite often) then what I do is customize my top-level layout class into one which overrides onMeasure(). The basic logic is that if the layout finds itself filling significantly less than the total area of the window, then a soft keyboard is probably showing.

import android.app.Activity;
import android.content.Context;
import android.graphics.Rect;
import android.util.AttributeSet;
import android.widget.LinearLayout;

/*
 * LinearLayoutThatDetectsSoftKeyboard - a variant of LinearLayout that can detect when 
 * the soft keyboard is shown and hidden (something Android can't tell you, weirdly). 
 */

public class LinearLayoutThatDetectsSoftKeyboard extends LinearLayout {

    public LinearLayoutThatDetectsSoftKeyboard(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public interface Listener {
        public void onSoftKeyboardShown(boolean isShowing);
    }
    private Listener listener;
    public void setListener(Listener listener) {
        this.listener = listener;
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        int height = MeasureSpec.getSize(heightMeasureSpec);
        Activity activity = (Activity)getContext();
        Rect rect = new Rect();
        activity.getWindow().getDecorView().getWindowVisibleDisplayFrame(rect);
        int statusBarHeight = rect.top;
        int screenHeight = activity.getWindowManager().getDefaultDisplay().getHeight();
        int diff = (screenHeight - statusBarHeight) - height;
        if (listener != null) {
            listener.onSoftKeyboardShown(diff>128); // assume all soft keyboards are at least 128 pixels high
        }
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);       
    }

    }

Then in your Activity class...

public class MyActivity extends Activity implements LinearLayoutThatDetectsSoftKeyboard.Listener {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ...
        LinearLayoutThatDetectsSoftKeyboard mainLayout = (LinearLayoutThatDetectsSoftKeyboard)findViewById(R.id.main);
        mainLayout.setListener(this);
        ...
    }


    @Override
    public void onSoftKeyboardShown(boolean isShowing) {
        // do whatever you need to do here
    }

    ...
}

Answer 2

So hopefully this helps someone out.

The new answer that Reuben Scratton gave is great and really efficient, but it really only works if you set your windowSoftInputMode to adjustResize. If you set it to adjustPan, it's still not possible to detect whether or not the keyboard is visible using his code snippet. To work around this, I made this tiny modification to the code above.

final View activityRootView = findViewById(R.id.activityRoot);
activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
    Rect r = new Rect();
    //r will be populated with the coordinates of your view that area still visible.
    activityRootView.getWindowVisibleDisplayFrame(r);
   
    int heightDiff = activityRootView.getRootView().getHeight() - r.height();
    if (heightDiff > 0.25*activityRootView.getRootView().getHeight()) { // if more than 25% of the screen, its probably a keyboard...
        ... do something here
    }
 }
}); 

Answer 3

It has been forever in terms of computer but this question is still unbelievably relevant!

So I've taken the above answers and have combined and refined them a bit...

public interface OnKeyboardVisibilityListener {


    void onVisibilityChanged(boolean visible);
}

public final void setKeyboardListener(final OnKeyboardVisibilityListener listener) {
    final View activityRootView = ((ViewGroup) getActivity().findViewById(android.R.id.content)).getChildAt(0);

    activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {

        private boolean wasOpened;

        private final int DefaultKeyboardDP = 100;

        // From @nathanielwolf answer...  Lollipop includes button bar in the root. Add height of button bar (48dp) to maxDiff
        private final int EstimatedKeyboardDP = DefaultKeyboardDP + (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP ? 48 : 0);

        private final Rect r = new Rect();

        @Override
        public void onGlobalLayout() {
            // Convert the dp to pixels.
            int estimatedKeyboardHeight = (int) TypedValue
                    .applyDimension(TypedValue.COMPLEX_UNIT_DIP, EstimatedKeyboardDP, activityRootView.getResources().getDisplayMetrics());

            // Conclude whether the keyboard is shown or not.
            activityRootView.getWindowVisibleDisplayFrame(r);
            int heightDiff = activityRootView.getRootView().getHeight() - (r.bottom - r.top);
            boolean isShown = heightDiff >= estimatedKeyboardHeight;

            if (isShown == wasOpened) {
                Log.d("Keyboard state", "Ignoring global layout change...");
                return;
            }

            wasOpened = isShown;
            listener.onVisibilityChanged(isShown);
        }
    });
}

Works for me :)

NOTE: If you notice that the DefaultKeyboardDP does not fit your device play with the value and post a comment for everyone to know what should be the value... eventually we will get the correct value to fit all devices!

Answer 4

Sorry for the late answer, but I had created a little helper class to handle open/close events with notifying listeners and other useful things, may be someone would find it helpful:

import android.graphics.Rect;
import android.view.View;
import android.view.ViewTreeObserver;

import java.util.LinkedList;
import java.util.List;

public class SoftKeyboardStateWatcher implements ViewTreeObserver.OnGlobalLayoutListener {

    public interface SoftKeyboardStateListener {
        void onSoftKeyboardOpened(int keyboardHeightInPx);
        void onSoftKeyboardClosed();
    }

    private final List<SoftKeyboardStateListener> listeners = new LinkedList<SoftKeyboardStateListener>();
    private final View activityRootView;
    private int        lastSoftKeyboardHeightInPx;
    private boolean    isSoftKeyboardOpened;

    public SoftKeyboardStateWatcher(View activityRootView) {
        this(activityRootView, false);
    }

    public SoftKeyboardStateWatcher(View activityRootView, boolean isSoftKeyboardOpened) {
        this.activityRootView     = activityRootView;
        this.isSoftKeyboardOpened = isSoftKeyboardOpened;
        activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(this);
    }

    @Override
    public void onGlobalLayout() {
        final Rect r = new Rect();
        //r will be populated with the coordinates of your view that area still visible.
        activityRootView.getWindowVisibleDisplayFrame(r);

        final int heightDiff = activityRootView.getRootView().getHeight() - (r.bottom - r.top);
        if (!isSoftKeyboardOpened && heightDiff > 100) { // if more than 100 pixels, its probably a keyboard...
            isSoftKeyboardOpened = true;
            notifyOnSoftKeyboardOpened(heightDiff);
        } else if (isSoftKeyboardOpened && heightDiff < 100) {
            isSoftKeyboardOpened = false;
            notifyOnSoftKeyboardClosed();
        }
    }

    public void setIsSoftKeyboardOpened(boolean isSoftKeyboardOpened) {
        this.isSoftKeyboardOpened = isSoftKeyboardOpened;
    }

    public boolean isSoftKeyboardOpened() {
        return isSoftKeyboardOpened;
    }

    /**
     * Default value is zero {@code 0}.
     *
     * @return last saved keyboard height in px
     */
    public int getLastSoftKeyboardHeightInPx() {
        return lastSoftKeyboardHeightInPx;
    }

    public void addSoftKeyboardStateListener(SoftKeyboardStateListener listener) {
        listeners.add(listener);
    }

    public void removeSoftKeyboardStateListener(SoftKeyboardStateListener listener) {
        listeners.remove(listener);
    }

    private void notifyOnSoftKeyboardOpened(int keyboardHeightInPx) {
        this.lastSoftKeyboardHeightInPx = keyboardHeightInPx;

        for (SoftKeyboardStateListener listener : listeners) {
            if (listener != null) {
                listener.onSoftKeyboardOpened(keyboardHeightInPx);
            }
        }
    }

    private void notifyOnSoftKeyboardClosed() {
        for (SoftKeyboardStateListener listener : listeners) {
            if (listener != null) {
                listener.onSoftKeyboardClosed();
            }
        }
    }
}

Usage example:

final SoftKeyboardStateWatcher softKeyboardStateWatcher 
    = new SoftKeyboardStateWatcher(findViewById(R.id.activity_main_layout);

// Add listener
softKeyboardStateWatcher.addSoftKeyboardStateListener(...);
// then just handle callbacks

Answer 5

Some improvements to avoid wrongly detect the visibility of soft keyboard on high density devices:

1. Threshold of height difference should be defined as 128 dp, not 128 pixels.
   Refer to Google design doc about Metrics and Grid, 48 dp is comfortable size for touch object and 32 dp is minimum for buttons. Generic soft keyboard should include 4 rows of key buttons, so minimum keyboard height should be: 32 dp * 4 = 128 dp, that means threshold size should transfer to pixels by multiply device density. For xxxhdpi devices (density 4), the soft keyboard height threshold should be 128 * 4 = 512 pixels.

2. Height difference between root view and its visible area:
   root view height - status bar height - visible frame height = root view bottom - visible frame bottom, since status bar height equal to the top of root view visible frame.

   private final String TAG = "TextEditor";
   private TextView mTextEditor;
   
   @Override
   protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_editor);
       mTextEditor = (TextView) findViewById(R.id.text_editor);
       mTextEditor.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
           @Override
           public void onGlobalLayout() {
               isKeyboardShown(mTextEditor.getRootView());
           }
       });
   }
   
   private boolean isKeyboardShown(View rootView) {
       /* 128dp = 32dp * 4, minimum button height 32dp and generic 4 rows soft keyboard */
       final int SOFT_KEYBOARD_HEIGHT_DP_THRESHOLD = 128;
   
       Rect r = new Rect();
       rootView.getWindowVisibleDisplayFrame(r);
       DisplayMetrics dm = rootView.getResources().getDisplayMetrics();
       /* heightDiff = rootView height - status bar height (r.top) - visible frame height (r.bottom - r.top) */
       int heightDiff = rootView.getBottom() - r.bottom;
       /* Threshold size: dp to pixels, multiply with display density */
       boolean isKeyboardShown = heightDiff > SOFT_KEYBOARD_HEIGHT_DP_THRESHOLD * dm.density;
   
       Log.d(TAG, "isKeyboardShown ? " + isKeyboardShown + ", heightDiff:" + heightDiff + ", density:" + dm.density
               + "root view height:" + rootView.getHeight() + ", rect:" + r);
   
       return isKeyboardShown;
   }

Wow, We have Good news Android Geeks. And its time to say goodbye to the old way. First I will add official release note to read and know more about these methods/ classes, and then we will see these amazing methods/ classes

Breaking Note: Do not add these into your release apps, until these classes/ methods are released

How to check keyboard visibility

val insets = ViewCompat.getRootWindowInsets(view)
val isKeyboardVisible = insets.isVisible(Type.ime())

Few other utilities

How to get the height of Keyboard

val insets = ViewCompat.getRootWindowInsets(view)
val keyboardHeight = insets.getInsets(Type.ime()).bottom

How to show/ hide the keyboard

Answer 7

I used a little time to figure this out... I ran it some CastExceptions, but figured out that you can replace you LinearLayout in the layout.xml with the name of the class.

Like this:

<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent"
    xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/llMaster">

<com.ourshoppingnote.RelativeLayoutThatDetectsSoftKeyboard android:background="@drawable/metal_background"
    android:layout_width="fill_parent" android:layout_height="fill_parent"
    android:id="@+id/rlMaster" >
    <LinearLayout android:layout_width="fill_parent"
        android:layout_height="1dip" android:background="@drawable/line"></LinearLayout>

          ....

</com.ourshoppingnote.RelativeLayoutThatDetectsSoftKeyboard>    


</LinearLayout>

That way you do not run into any cast issues.

... and if you don't want to do this on every page, I recommend that you use "MasterPage in Android". See the link here: http://jnastase.alner.net/archive/2011/01/08/ldquomaster-pagesrdquo-in-android.aspx

Answer 8

The idea is, if you need to hide your keyboard and check soft input state at the same time, use the following solution:

public boolean hideSoftInput() {
    InputMethodManager imm = (InputMethodManager) getSystemService(Activity.INPUT_METHOD_SERVICE);
    return imm.hideSoftInputFromWindow(mViewPager.getWindowToken(), 0);
}

This method returns true if keyboard was shown before hiding.

Answer 9

Checking the height of elements is not reliable because some keyboards like WifiKeyboard have zero height.

Instead, you can use the callback result of showSoftInput() and hideSoftInput() to check for the status of the keyboard. Full details and example code at

Answer 10

You can observe softkeyboard's hide by using activity's decorView.

public final class SoftKeyboardUtil {
    public static final String TAG = "SoftKeyboardUtil";
    public static void observeSoftKeyBoard(Activity activity , final OnSoftKeyBoardHideListener listener){
        final View decorView = activity.getWindow().getDecorView();
        decorView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
            @Override
            public void onGlobalLayout() {
                Rect rect = new Rect();
                decorView.getWindowVisibleDisplayFrame(rect);
                int displayHight = rect.bottom - rect.top;
                int hight = decorView.getHeight();
                boolean hide = (double)displayHight / hight > 0.8 ;
                if(Log.isLoggable(TAG, Log.DEBUG)){
                    Log.d(TAG ,"DecorView display hight = "+displayHight);
                    Log.d(TAG ,"DecorView hight = "+ hight);
                    Log.d(TAG, "softkeyboard visible = " + !hide);
                }

                listener.onSoftKeyBoardVisible(!hide);

            }
        });
    }



    public interface OnSoftKeyBoardHideListener{
        void onSoftKeyBoardVisible(boolean visible);
    }
}

Answer 11

Instead of assuming the difference coding I did something like this, as I dint had menu options in my application.

final View root= findViewById(R.id.myrootview); 
root.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
@Override
    public void onGlobalLayout() {
        int heightDiff = root.getRootView().getHeight() - root.getHeight();

        Rect rectgle= new Rect();
        Window window= getWindow();
        window.getDecorView().getWindowVisibleDisplayFrame(rectgle);
        int contentViewTop=                     
          window.findViewById(Window.ID_ANDROID_CONTENT).getTop();
        if(heightDiff <= contentViewTop){
            //Soft KeyBoard Hidden
        }else{
            //Soft KeyBoard Shown
        }
     }
});

Answer 12

There is also solution with system insets, but it works only with API >= 21 (Android L). Say you have BottomNavigationView, which is child of LinearLayout and you need to hide it when keyboard is shown:

> LinearLayout
  > ContentView
  > BottomNavigationView

All you need to do is to extend LinearLayout in such way:

public class KeyboardAwareLinearLayout extends LinearLayout {
    public KeyboardAwareLinearLayout(Context context) {
        super(context);
    }

    public KeyboardAwareLinearLayout(Context context, @Nullable AttributeSet attrs) {
        super(context, attrs);
    }

    public KeyboardAwareLinearLayout(Context context,
                                     @Nullable AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    public KeyboardAwareLinearLayout(Context context, AttributeSet attrs,
                                     int defStyleAttr, int defStyleRes) {
        super(context, attrs, defStyleAttr, defStyleRes);
    }

    @Override
    public WindowInsets onApplyWindowInsets(WindowInsets insets) {
        int childCount = getChildCount();
        for (int index = 0; index < childCount; index++) {
            View view = getChildAt(index);
            if (view instanceof BottomNavigationView) {
                int bottom = insets.getSystemWindowInsetBottom();
                if (bottom >= ViewUtils.dpToPx(200)) {
                    // keyboard is shown
                    view.setVisibility(GONE);
                } else {
                    // keyboard is hidden
                    view.setVisibility(VISIBLE);
                }
            }
        }
        return insets;
    }
}

The idea is that when keyboard is shown, system insets are changed with pretty big .bottom value.

Answer 13

There's a hidden method can help for this, InputMethodManager.getInputMethodWindowVisibleHeight. But I don't know why it's hidden.

import android.content.Context
import android.os.Handler
import android.view.inputmethod.InputMethodManager

class SoftKeyboardStateWatcher(private val ctx: Context) {
  companion object {
    private const val DELAY = 10L
  }

  private val handler = Handler()
  private var isSoftKeyboardOpened: Boolean = false

  private val height: Int
    get() {
      val imm = ctx.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
      val method = imm.javaClass.getMethod("getInputMethodWindowVisibleHeight")
      method.isAccessible = true
      return method.invoke(imm) as Int
    }

  private val task: Runnable by lazy {
    Runnable {
      start()
      if (!isSoftKeyboardOpened && height > 0) {
        isSoftKeyboardOpened = true
        notifyOnSoftKeyboardOpened(height)
      } else if (isSoftKeyboardOpened && height == 0) {
        isSoftKeyboardOpened = false
        notifyOnSoftKeyboardClosed()
      }
    }
  }

  var listener: SoftKeyboardStateListener? = null

  interface SoftKeyboardStateListener {
    fun onSoftKeyboardOpened(keyboardHeightInPx: Int)
    fun onSoftKeyboardClosed()
  }

  fun start() {
    handler.postDelayed(task, DELAY)
  }

  fun stop() {
    handler.postDelayed({
      if (!isSoftKeyboardOpened) handler.removeCallbacks(task)
    }, DELAY * 10)
  }

  private fun notifyOnSoftKeyboardOpened(keyboardHeightInPx: Int) {
    listener?.onSoftKeyboardOpened(keyboardHeightInPx)
  }

  private fun notifyOnSoftKeyboardClosed() {
    listener?.onSoftKeyboardClosed()
  }
}

Answer 14

I found that a combination of @Reuben_Scratton's method along with @Yogesh's method seems to work best. Combining their methods would yield something like this:

final View activityRootView = findViewById(R.id.activityRoot);
activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
  @Override
  public void onGlobalLayout() {
    if (getResources().getConfiguration().keyboardHidden == Configuration.KEYBOARDHIDDEN_NO) { // Check if keyboard is not hidden
       // ... do something here
    }
  }
});

Answer 15

None of these solutions will work for Lollipop as is. In Lollipop activityRootView.getRootView().getHeight() includes the height of the button bar, while measuring the view does not. I've adapted the best/simplest solution above to work with Lollipop.

    final View activityRootView = findViewById(R.id.activityRoot);
activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
  @Override
  public void onGlobalLayout() {
    Rect r = new Rect();
    //r will be populated with the coordinates of your view that area still visible.
    activityRootView.getWindowVisibleDisplayFrame(r);

    int heightDiff = activityRootView.getRootView().getHeight() - (r.bottom - r.top);
    Resources res = getResources();
    // The status bar is 25dp, use 50dp for assurance
    float maxDiff =
        TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 50, res.getDisplayMetrics());

    //Lollipop includes button bar in the root. Add height of button bar (48dp) to maxDiff
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
      float buttonBarHeight =
          TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 48, res.getDisplayMetrics());
      maxDiff += buttonBarHeight;
    }
    if (heightDiff > maxDiff) { // if more than 100 pixels, its probably a keyboard...
      ...do something here
    }
  }
});

Answer 16

I have just encountered a bug while using most of the solutions above that suggest adding a fixed number.

S4 is has a high dpi which resulted in the navigation bar's height being 100px thus my app thinking that the keyboard is open all the time.

So with all the new high res phones being released i believe using a hard coded value is not a good idea for long term.

A better approach that i found after some testing on various screens and devices was to use percentage. Get the difference between decorView and ur app content and afterwards check what is the percentage of that difference. From the stats that i got, most nav bar(regardless of the size, resolution etc..) will take between 3% to 5% of the screen. Where as if the keyboard is open it was taking between 47% to 55% of the screen.

As a conclusion my solution was to check if the diff is more than 10% then i assume its a keyboard open.

Answer 17

I used a slight variant of Reuban's answer, which proved to be more helpful in certain circumstances, especially with high resolution devices.

final View activityRootView = findViewById(android.R.id.content);
activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(
        new OnGlobalLayoutListener() {
            @Override
            public void onGlobalLayout() {
                int heightView = activityRootView.getHeight();
                int widthView = activityRootView.getWidth();
                if (1.0 * widthView / heightView > 3) {
                    //Make changes for Keyboard not visible
                } else {
                    //Make changes for keyboard visible
                }
            }
        });

Answer 18

It has been forever in terms of the computer but this question is still unbelievably relevant! So I've taken the above answers and have combined and refined them a bit...

public interface OnKeyboardVisibilityListener {
    void onVisibilityChanged(boolean visible);
}

public final void setKeyboardListener(final OnKeyboardVisibilityListener listener) {
    final View activityRootView = ((ViewGroup) getActivity().findViewById(android.R.id.content)).getChildAt(0);
    activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {

        private boolean wasOpened;

    private final Rect r = new Rect();

        @Override
        public void onGlobalLayout() {
            activityRootView.getWindowVisibleDisplayFrame(r);

            int heightDiff = activityRootView.getRootView().getHeight() - (r.bottom - r.top);
            boolean isOpen = heightDiff > 100;
            if (isOpen == wasOpened) {
                logDebug("Ignoring global layout change...");
                return;
            }

            wasOpened = isOpen;
            listener.onVisibilityChanged(isOpen);
        }
    });
}

It works for me.

Answer 19

Try this:

final View activityRootView = getWindow().getDecorView().getRootView();
activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
    @Override
    public void onGlobalLayout() {
        Rect r = new Rect();
        //r will be populated with the coordinates of your view that area still visible.
        activityRootView.getWindowVisibleDisplayFrame(r);

        int heightDiff = activityRootView.getRootView().getHeight() - (r.bottom - r.top);
        if (heightDiff < activityRootView.getRootView().getHeight() / 4 ) { // if more than 100 pixels, its probably a keyboard...
             // ... do something here ... \\
        }
    }
});

Answer 20

My answer is basically the same as Kachi's answer, but I wrapped it into a nice helper class to clean up the way it's used throughout my app.

import android.app.Activity;
import android.app.Fragment;
import android.graphics.Rect;
import android.view.View;
import android.view.ViewTreeObserver.OnGlobalLayoutListener;

/**
 * Detects Keyboard Status changes and fires events only once for each change
 */
public class KeyboardStatusDetector {
    KeyboardVisibilityListener visibilityListener;

    boolean keyboardVisible = false;

    public void registerFragment(Fragment f) {
        registerView(f.getView());
    }

    public void registerActivity(Activity a) {
        registerView(a.getWindow().getDecorView().findViewById(android.R.id.content));
    }

    public KeyboardStatusDetector registerView(final View v) {
        v.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
            @Override
            public void onGlobalLayout() {
                Rect r = new Rect();
                v.getWindowVisibleDisplayFrame(r);

                int heightDiff = v.getRootView().getHeight() - (r.bottom - r.top);
                if (heightDiff > 100) { // if more than 100 pixels, its probably a keyboard...
                    /** Check this variable to debounce layout events */
                    if(!keyboardVisible) {
                        keyboardVisible = true;
                        if(visibilityListener != null) visibilityListener.onVisibilityChanged(true);
                    }
                } else {
                    if(keyboardVisible) {
                        keyboardVisible = false;
                        if(visibilityListener != null) visibilityListener.onVisibilityChanged(false);
                    }
                }
            }
        });

        return this;
    }

    public KeyboardStatusDetector setVisibilityListener(KeyboardVisibilityListener listener) {
        visibilityListener = listener;
        return this;
    }

    public static interface KeyboardVisibilityListener {
        public void onVisibilityChanged(boolean keyboardVisible);
    }
}

You can use this to detect keyboard changes anywhere throughout the app like this:

    new KeyboardStatusDetector()
            .registerFragment(fragment)  //register to a fragment 
            .registerActivity(activity)  //or register to an activity
            .registerView(view)          //or register to a view
            .setVisibilityListener(new KeyboardVisibilityListener() {
                @Override
                public void onVisibilityChanged(boolean keyboardVisible) {
                    if(keyboardVisible) {
                       //Do stuff for keyboard visible
                    }else {
                       //Do stuff for keyboard hidden
                    }
                }
            });

Note: only use one of the "register" calls. They all work the same and are only there for convenience

Answer 21

you can try this, work great for me:

InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);

if (imm.isAcceptingText()) {
    //Software Keyboard was shown..
} else {
    //Software Keyboard was not shown..
}

Answer 22

I was having difficulty maintaining keyboard state when changing orientation of fragments within a viewpager. I'm not sure why, but it just seems to be wonky and acts differently from a standard Activity.

To maintain keyboard state in this case, first you should add android:windowSoftInputMode = "stateUnchanged" to your AndroidManifest.xml. You may notice, though, that this doesn't actually solve the entire problem -- the keyboard didn't open for me if it was previously opened before orientation change. In all other cases, the behavior seemed to be correct.

Then, we need to implement one of the solutions mentioned here. The cleanest one I found was George Maisuradze's--use the boolean callback from hideSoftInputFromWindow:

InputMethodManager imm = (InputMethodManager) getSystemService(Activity.INPUT_METHOD_SERVICE);
return imm.hideSoftInputFromWindow(mViewPager.getWindowToken(), 0);

I stored this value in my Fragment's onSaveInstanceState method and retrieved it onCreate. Then, I forcibly showed the keyboard in onCreateView if it had a value of true (it returns true if the keyboard is visible before actually hiding it prior to the Fragment destruction).

Answer 23

according to the doc.. https://developer.android.com/reference/androidx/core/view/WindowInsetsCompat

check release note.. https://developer.android.com/jetpack/androidx/releases/core#1.5.0-alpha02

To get the current keyboard visibility, you can use getRootWindowInsets, and then call the isVisible() function, passing in the IME type.

val windowinsetscompat = ViewCompat.getRootWindowInsets(view)
val imeVisible = windowinsetscompat.isVisible(Type.ime())

there is also listener for changes OnApplyWindowInsetsListener

ViewCompat.setOnApplyWindowInsetsListener(view) { v, insets ->
    val imeVisible = insets.isVisible(Type.ime())
}

Answer 24

Here's my solution, and it works. Instead of looking for pixel size just check that the height of the content view has changed or not:

// Scroll to the latest comment whenever the keyboard is shown
commentsContent.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {

        private int oldHeight;

        @Override
        public void onGlobalLayout() {
            int newHeight = commentsContent.getMeasuredHeight();
            if (newHeight < oldHeight) {
                // Check for the keyboard showing in case the height difference
                // is a result of orientation change
                if (isSoftKeyboardShowing(CommentsActivity.this)) {
                    // Keyboard is showing so scroll to the latest comment
                    scrollToLatestComment();
                }
            }
            oldHeight = newHeight;
        }

    });


public static boolean isSoftKeyboardShowing(Activity activity) {
    InputMethodManager inputMethodManager = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
    return inputMethodManager.isActive();
}

Answer 25

Don't make any hard code. Best way is you have to resize your views while on Get Focus on EditText with KeyBord Show. You can do this adding resize property on activity into Manifest file using below code.

android:windowSoftInputMode="adjustResize"

Answer 26

There is a direct method to find this out. And, it does not require any Layout changes.
So, it works in immersive fullscreen mode, too.

The trick is that you try to hide or show the soft keyboard and capture the result of that try.
No panic, this does not really show or hide the keyboard. We just ask for the state.

To stay up-to-date, you can simply repeat the operation, e.g. every 200 milliseconds, using a Handler.

You find an implementation here: https://stackoverflow.com/a/27567074/2525452

Answer 27

i think this method will help you to find out is keybord is visible or not.

 public Boolean isSoftKeyBoardVisible(){
    InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);

    if (imm.isAcceptingText()) {
        Log.d(TAG,"Software Keyboard was shown");
        return true;
    } else {
        Log.d(TAG,"Software Keyboard was not shown");
        return false;
    }

}

Answer 28

99% of solutions here are based on probability of IME WINDOW SIZE and each such solution is a sh... worth!

because:

1. OVERLAYS - from User apps or System apps
2. IME have no MINIMUM SIZE it can take 100% of window size and can be so thin as imagination of developer implementation :)
3. MODAL windows / MULTI windows
4. and many many more like no knowledge of IPC (eg: foreign window or its content detection)

so guessing it's IME is always wrong - don't guess be sure !!!

@kevin-du is best solution wright now as its query IMM for IME height - but as it said the method is hidden API so using it could be dangerous in the way of getting wrong "false negative results" - by wrong dev usage.

Answer 29

Reuben Scratton's new answer (calculate the HeightDiff int heightDiff = activityRootView.getRootView().getHeight() - activityRootView.getHeight(); ) will not work in activity if you set the translucent status bar mode.

if you use translucent status bar , activityRootView.getHeight() will never change weather the soft keyboard is visible. it will always return the height of activity and status bar.

For example, Nexus 4, Android 5.0.1, set android:windowTranslucentStatus to true, it will return 1184 forever, even the ime have opend. If you set android:windowTranslucentStatus to false, it will return Height correctly, if ime invisible,it return 1134(not include the status bar)。close the ime, it will return 5xx maybe (depends on ime's height)

I don't know weather this is a bug, I've try on 4.4.4 and 5.0.1, the result is same.

So, up to now, the second most agreed answer, Kachi's solution will be the most safe way to calcute the height of ime. Here's a copy:

final View activityRootView = findViewById(R.id.activityRoot);
activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new        OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
Rect r = new Rect();
//r will be populated with the coordinates of your view that area still visible.
activityRootView.getWindowVisibleDisplayFrame(r);

int heightDiff = activityRootView.getRootView().getHeight() - (r.bottom - r.top);
if (heightDiff > 100) { // if more than 100 pixels, its probably a keyboard...
    ... do something here
    }
 }
}); 

Answer 30

A method that doesn't need a LayoutListener

In my case, I would like to save the state of the keyboard before replacing my Fragment. I call the method hideSoftInputFromWindow from onSaveInstanceState, which closes the keyboard and returns me whether the keyboard was visible or not.

This method is straightforward but may change the state of your keyboard.
