How to adjust layout when soft keyboard appears

Question

I would like to adjust/re-size the layout when the soft-keyboard activated, as below:

Before and After:

---

Found couple resources in SO:

1. How to keep all fields and texts visible while the soft keyboard is shown
2. android soft keyboard spoils layout when appears
3. Adjust layout when soft keyboard is on

---

But the questions & answers are rather ambiguous, here's the question with clearer picture of what I want.

Requirements:

• It should work on phone with any screen sizes.
• Noticed that the margin/padding space at "FACEBOOK" and "Sign Up for Facebook" has changed before and after.
• No scroll view is involved.

Answer 1

Just add

android:windowSoftInputMode="adjustResize"

in your AndroidManifest.xml where you declare this particular activity and this will adjust the layout resize option.

some source code below for layout design

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="20dp"
        android:text="FaceBook"
        android:textAppearance="?android:attr/textAppearanceLarge" />

    <EditText
        android:id="@+id/editText1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/textView1"
        android:layout_marginTop="30dp"
        android:ems="10"
        android:hint="username" >

        <requestFocus />
    </EditText>

    <EditText
        android:id="@+id/editText2"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/editText1"
        android:layout_marginTop="20dp"
        android:ems="10"
        android:hint="password" />

    <Button
        android:id="@+id/button1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/editText2"
        android:layout_centerHorizontal="true"
        android:layout_marginLeft="18dp"
        android:layout_marginTop="20dp"
        android:text="Log In" />

    <TextView
        android:id="@+id/textView2"
        android:layout_width="match_parent"

        android:layout_alignParentBottom="true"
        android:layout_marginTop="17dp"
        android:gravity="center"
        android:text="Sign up for facebook"
        android:textAppearance="?android:attr/textAppearanceLarge" />

</RelativeLayout>

This question has beeen asked a few years ago and "Secret Andro Geni" has a good base explanation and "tir38" also made a good attempt on the complete solution, but alas there is no complete solution posted here. I've spend a couple of hours figuring out things and here is my complete solution with detailed explanation at the bottom:

                </RelativeLayout>

            </LinearLayout>

        </RelativeLayout>

    </RelativeLayout>

</ScrollView>

And in AndroidManifest.xml, don't forget to set:

android:windowSoftInputMode="adjustResize"

on the <activity> tag that you want such layout.

Thoughts:

I've realized that RelativeLayout are the layouts that span thru all available space and are then resized when the keyboard pops up.

And LinearLayout are layouts that don't get resized in the resizing process.

That's why you need to have 1 RelativeLayout immediately after ScrollView to span thru all available screen space. And you need to have a LinearLayout inside a RelativeLayout else your insides would get crushed when the resizing occurs. Good example is "headerLayout". If there wouldn't be a LinearLayout inside that RelativeLayout "facebook" text would get crushed and wouldn't be shown.

In the "facebook" login pictures posted in the question I've also noticed that the whole login part (mainLayout) is centered vertical in relation to the whole screen, hence the attribute:

android:layout_centerVertical="true"

on the LinearLayout layout. And because mainLayout is inside a LinearLayout this means that that part does't get resized (again see picture in question).

Answer 3

Add this line in your Manifest where your Activity is called

android:windowSoftInputMode="adjustPan|adjustResize"

or

you can add this line in your onCreate

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE|WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);

Answer 4

It can work for all kind of layout.

1. add this to your activity tag in AndroidManifest.xml

android:windowSoftInputMode="adjustResize"

for example:

<activity android:name=".ActivityLogin"
    android:screenOrientation="portrait"
    android:theme="@style/AppThemeTransparent"
    android:windowSoftInputMode="adjustResize"/>

2. add this on your layout tag in activitypage.xml that will change its position.

android:fitsSystemWindows="true"

and

android:layout_alignParentBottom="true"

for example:

<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:fitsSystemWindows="true">

Answer 5

Android Developer has the right answer, but the provided source code is pretty verbose and doesn't actually implement the pattern described in the diagram.

Here is a better template:

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:fillViewport="true">

    <RelativeLayout android:layout_width="match_parent"
                    android:layout_height="match_parent">

        <LinearLayout android:layout_width="match_parent"
                      android:layout_height="wrap_content"
                      android:orientation="vertical">

                <!-- stuff to scroll -->

        </LinearLayout>

        <FrameLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true">

            <!-- footer -->

        </FrameLayout>

    </RelativeLayout>

</ScrollView>

Its up to you to decide what views you use for the "scrolling" and "footer" parts. Also know that you probably have to set the ScrollViews fillViewPort .

Answer 6

This makes it possible to show any wanted layout previously hidden by the keyboard.

Add this to the activity tag in AndroidManifest.xml

android:windowSoftInputMode="adjustResize"

Surround your root view with a ScrollView, preferably with scrollbars=none. The ScrollView will properly not change any thing with your layout except be used to solve this problem.

And then set fitsSystemWindows="true" on the view that you want to make fully shown above the keyboard. This will make your EditText visible above the keyboard, and make it possible to scroll down to the parts below the EditText but in the view with fitsSystemWindows="true".

android:fitsSystemWindows="true"

For example:

<ScrollView
    android:id="@+id/scrollView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:scrollbars="none">

    <android.support.constraint.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:fitsSystemWindows="true">

        ...

    </android.support.constraint.ConstraintLayout>
</ScrollView>   

If you want to show the full part of fitsSystemWindows="true" view above the keyboard in the moment the keyboard appears, you will need some code to scroll the view to the bottom:

// Code is in Kotlin

setupKeyboardListener(scrollView) // call in OnCreate or similar


private fun setupKeyboardListener(view: View) {
    view.viewTreeObserver.addOnGlobalLayoutListener {
        val r = Rect()
        view.getWindowVisibleDisplayFrame(r)
        if (Math.abs(view.rootView.height - (r.bottom - r.top)) > 100) { // if more than 100 pixels, its probably a keyboard...
            onKeyboardShow()
        }
    }
}

private fun onKeyboardShow() {
    scrollView.scrollToBottomWithoutFocusChange()
}

fun ScrollView.scrollToBottomWithoutFocusChange() { // Kotlin extension to scrollView
    val lastChild = getChildAt(childCount - 1)
    val bottom = lastChild.bottom + paddingBottom
    val delta = bottom - (scrollY + height)
    smoothScrollBy(0, delta)
}

Full layout example:

<android.support.constraint.ConstraintLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:fitsSystemWindows="true">

    <RelativeLayout
        android:id="@+id/statisticsLayout"
        android:layout_width="match_parent"
        android:layout_height="340dp"
        android:background="@drawable/some"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent">

        <ImageView

    </RelativeLayout>

</android.support.constraint.ConstraintLayout>

Answer 7

For those using ConstraintLayout, android:windowSoftInputMode="adjustPan|adjustResize" will not work.

What you can do is use a soft keyboard listener, set constraints of the views from bottom to bottom of the upper views, then set a vertical bias for each view (as a positional percentage between constraints) to a horizontal guideline (also positioned by percentage, but to the parent).

For each view, we just need to change app:layout_constraintBottom_toBottomOf to @+id/guideline when the keyboard is shown, programmatically of course.

        <ImageView
        android:id="@+id/loginLogo"
        ...
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintVertical_bias="0.15" />


        <RelativeLayout
        android:id="@+id/loginFields"
        ...
        app:layout_constraintVertical_bias=".15"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/loginLogo">

        <Button
        android:id="@+id/login_btn"
        ...
        app:layout_constraintVertical_bias=".25"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/loginFields"/>

Generally a soft keyboard takes up no more than 50% of the height of the screen. Thus, you can set the guideline at 0.5.

        <android.support.constraint.Guideline
        android:id="@+id/guideline"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        app:layout_constraintGuide_percent="0.5"/>

Now programmatically, when the keyboard is not shown, we can set all the app:layout_constraintBottom_toBottomOf back to parent, vice-versa.

            unregistrar = KeyboardVisibilityEvent.registerEventListener(this, isOpen -> {
            loginLayout.startAnimation(AnimationManager.getFade(200));
            if (isOpen) {
                setSoftKeyViewParams(loginLogo, R.id.guideline, ConstraintLayout.LayoutParams.PARENT_ID, -1, "235:64", 0.15f,
                        63, 0, 63, 0);
                setSoftKeyViewParams(loginFields, R.id.guideline, -1, R.id.loginLogo, null, 0.15f,
                        32, 0, 32, 0);
                setSoftKeyViewParams(loginBtn, R.id.guideline, -1, R.id.useFingerPrintIdText, null, 0.5f,
                        32, 0, 32, 0);
            } else {
                setSoftKeyViewParams(loginLogo, ConstraintLayout.LayoutParams.PARENT_ID, ConstraintLayout.LayoutParams.PARENT_ID, -1, "235:64", 0.15f,
                        63, 0, 63, 0);
                setSoftKeyViewParams(loginFields, ConstraintLayout.LayoutParams.PARENT_ID, -1, R.id.loginLogo,null, 0.15f,
                        32, 0, 32, 0);
                setSoftKeyViewParams(loginBtn, ConstraintLayout.LayoutParams.PARENT_ID, -1, R.id.useFingerPrintIdText,null, 0.25f,
                        32, 0, 32, 0);
            }
        });

Call this method:

    private void setSoftKeyViewParams(View view, int bottomToBottom, int topToTop, int topToBottom, String ratio, float verticalBias,
                                  int left, int top, int right, int bottom) {
    ConstraintLayout.LayoutParams viewParams = new ConstraintLayout.LayoutParams(view.getLayoutParams().width, view.getLayoutParams().height);
    viewParams.dimensionRatio = ratio;
    viewParams.bottomToBottom = bottomToBottom;
    viewParams.topToTop = topToTop;
    viewParams.topToBottom = topToBottom;
    viewParams.endToEnd = ConstraintLayout.LayoutParams.PARENT_ID;
    viewParams.startToStart = ConstraintLayout.LayoutParams.PARENT_ID;
    viewParams.verticalBias = verticalBias;
    viewParams.setMargins(Dimensions.dpToPx(left), Dimensions.dpToPx(top), Dimensions.dpToPx(right), Dimensions.dpToPx(bottom));
    view.setLayoutParams(viewParams);
}

The important thing is to be sure to set the vertical bias in a way that would scale correctly when the keyboard is shown and not shown.

Answer 8

Many answers are right. In AndroidManifest I wrote:

<activity
    android:name=".SomeActivity"
    android:configChanges="orientation|keyboardHidden|screenSize" // Optional, doesn't affect.
    android:theme="@style/AppTheme.NoActionBar"
    android:windowSoftInputMode="adjustResize" />

In my case I added a theme in styles.xml, but you can use your own:

<style name="AppTheme.NoActionBar" parent="AppTheme">
    <!--  Hide ActionBar -->
    <item name="windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
</style>

I noiced that if I use full-screen theme, resizing doesn't occur:

<style name="AppTheme.FullScreenTheme" parent="AppTheme">
    <!--  Hide ActionBar -->
    <item name="windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
    <!--  Hide StatusBar -->
    <item name="android:windowFullscreen">true</item>
</style>

Also in my case adjustResize works, but adjustPan doesn't.

For full-screen layouts see a workaround in Android How to adjust layout in Full Screen Mode when softkeyboard is visible or in https://gist.github.com/grennis/2e3cd5f7a9238c59861015ce0a7c5584.

Also https://medium.com/@sandeeptengale/problem-solved-3-android-full-screen-view-translucent-scrollview-adjustresize-keyboard-b0547c7ced32 works, but it's StatusBar is transparent, so battery, clock, Wi-Fi icons are visible.

If you create an activity with File > New > Activity > Fullscreen Activity, where in code is used:

fullscreen_content.systemUiVisibility =
    View.SYSTEM_UI_FLAG_LOW_PROFILE or
    View.SYSTEM_UI_FLAG_FULLSCREEN or
    View.SYSTEM_UI_FLAG_LAYOUT_STABLE or
    View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY or
    View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION or
    View.SYSTEM_UI_FLAG_HIDE_NAVIGATION

you also won't achieve a result. You can use android:fitsSystemWindows="true" in a root container, but StatusBar appears. So use workarounds from the first link.

Answer 9

You can simply set these options in the AndroidManifest.xml file.

<activity
    android:name=".YourACtivityName"
    android:windowSoftInputMode="stateVisible|adjustResize">

The use of adjustPan is not recommended by Google because the user may need to close the keyboard to see all the input fields.

Answer 10

For me it worked with this line of code:

getActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);

Just put it into onCreate method. Best!

Answer 11

In my case it helped.

main_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_main2"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:orientation="vertical"
    tools:context="com.livewallpaper.profileview.loginact.Main2Activity">

<TextView
    android:layout_weight="1"
    android:layout_width="match_parent"
    android:text="Title"
    android:gravity="center"
    android:layout_height="0dp" />
<LinearLayout
    android:layout_weight="1"
    android:layout_width="match_parent"
    android:layout_height="0dp">
    <EditText
        android:hint="enter here"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />
</LinearLayout>
<TextView
    android:layout_weight="1"
    android:text="signup for App"
    android:gravity="bottom|center_horizontal"
    android:layout_width="match_parent"
    android:layout_height="0dp" />
</LinearLayout>

Use this in manifest file

<activity android:name=".MainActivity"
        android:screenOrientation="portrait"
        android:windowSoftInputMode="adjustResize"/>

Now the most important part! Use theme like this in either Activity or Application tag.

android:theme="@style/AppTheme"

And the theme tooks like this

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
    <item name="windowActionModeOverlay">true</item>
</style>

So I was missing the theme. Which made me frustrated all day.

Answer 12

In Kotlin or in ConstraintLayout you just add :

android:windowSoftInputMode="stateHidden|adjustResize"

OR

android:windowSoftInputMode="stateVisible|adjustResize"

Which state you need after activity launch, you can set from manifest.

in your AndroidManifest.xml like this:

      <activity
        android:name=".ActivityName"
        android:windowSoftInputMode="stateHidden|adjustResize"
        />

Answer 13

Easy way in kotlin

In your fragment

requireActivity().window.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE or WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN)

In your layout :

android:fitsSystemWindows="true"

Answer 14

I use this Extended class frame And when I need to recalculate the height size onLayout I override onmeasure and subtract keyboardHeight using getKeyboardHeight()

My create frame who needs resize with softkeyboard

SizeNotifierFrameLayout frameLayout = new SizeNotifierFrameLayout(context) {
            private boolean first = true;

            @Override
            protected void onLayout(boolean changed, int left, int top, int right, int bottom) {
                super.onLayout(changed, left, top, right, bottom);

                if (changed) {
                    fixLayoutInternal(first);
                    first = false;
                }
            }

            @Override
            protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
                super.onMeasure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(MeasureSpec.getSize(heightMeasureSpec) - getKeyboardHeight(), MeasureSpec.EXACTLY));
            }

            @Override
            protected boolean drawChild(Canvas canvas, View child, long drawingTime) {
                boolean result = super.drawChild(canvas, child, drawingTime);
                if (child == actionBar) {
                    parentLayout.drawHeaderShadow(canvas, actionBar.getMeasuredHeight());
                }
                return result;
            }


        };

Add this line into Manifiest File:

android:windowSoftInputMode="adjustResize"

Answer 16

This code works for me. When keyboard appears, you can scroll screen

In AndroidManifest.xml

<activity android:name=".signup.screen_2.SignUpNameAndPasswordActivity"
