I have implemented a custom dialog for my application. I want to implement that when the user clicks outside the dialog, the dialog will be dismissed. What do I have to do for this?

You can use dialog.setCanceledOnTouchOutside(true);
which will close the dialog if you touch outside of the dialog.
Something like,
Dialog dialog = new Dialog(context)
dialog.setCanceledOnTouchOutside(true);
Or if your Dialog in non-model then,
1 - Set the flag-FLAG_NOT_TOUCH_MODAL
for your dialog's window attribute
Window window = this.getWindow();
window.setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL,
WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL);
2 - Add another flag to windows properties,, FLAG_WATCH_OUTSIDE_TOUCH
- this one is for dialog to receive touch event outside its visible region.
3 - Override onTouchEvent()
of dialog and check for action type. if the action type is
'MotionEvent.ACTION_OUTSIDE
' means, user is interacting outside the dialog region. So in this case, you can dimiss your dialog or decide what you wanted to perform.
view plainprint?
public boolean onTouchEvent(MotionEvent event)
{
if(event.getAction() == MotionEvent.ACTION_OUTSIDE){
System.out.println("TOuch outside the dialog ******************** ");
this.dismiss();
}
return false;
}

You can use this implementation of onTouchEvent. It prevent from reacting underneath activity to the touch event (as mentioned howettl).
@Override
public boolean onTouchEvent ( MotionEvent event ) {
// I only care if the event is an UP action
if ( event.getAction () == MotionEvent.ACTION_UP ) {
// create a rect for storing the window rect
Rect r = new Rect ( 0, 0, 0, 0 );
// retrieve the windows rect
this.getWindow ().getDecorView ().getHitRect ( r );
// check if the event position is inside the window rect
boolean intersects = r.contains ( (int) event.getX (), (int) event.getY () );
// if the event is not inside then we can close the activity
if ( !intersects ) {
// close the activity
this.finish ();
// notify that we consumed this event
return true;
}
}
// let the system handle the event
return super.onTouchEvent ( event );
}

This method should completely avoid activities below the grey area retrieving click events.
Remove this line if you have it:
window.setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL, WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL);
Put this on your activity created
getWindow().setFlags(LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH, LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH);
then override the touch event with this
@Override
public boolean onTouchEvent(MotionEvent ev)
{
if(MotionEvent.ACTION_DOWN == ev.getAction())
{
Rect dialogBounds = new Rect();
getWindow().getDecorView().getHitRect(dialogBounds);
if (!dialogBounds.contains((int) ev.getX(), (int) ev.getY())) {
// You have clicked the grey area
displayYourDialog();
return false; // stop activity closing
}
}
// Touch events inside are fine.
return super.onTouchEvent(ev);
}
This code is use for when use click on dialogbox that time hidesoftinput and when user click outer side of dialogbox that time both softinput and dialogbox are close.
dialog = new Dialog(act) {
@Override
public boolean onTouchEvent(MotionEvent event) {
// Tap anywhere to close dialog.
Rect dialogBounds = new Rect();
getWindow().getDecorView().getHitRect(dialogBounds);
if (!dialogBounds.contains((int) event.getX(),
(int) event.getY())) {
// You have clicked the grey area
InputMethodManager inputMethodManager = (InputMethodManager) act
.getSystemService(act.INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow(dialog
.getCurrentFocus().getWindowToken(), 0);
dialog.dismiss();
// stop activity closing
} else {
InputMethodManager inputMethodManager = (InputMethodManager) act
.getSystemService(act.INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow(dialog
.getCurrentFocus().getWindowToken(), 0);
}
return true;
}
};
Another solution, this code was taken from android source code of Window
You should just add these Two methods to your dialog source code.
@Override
public boolean onTouchEvent(MotionEvent event) {
if (isShowing() && (event.getAction() == MotionEvent.ACTION_DOWN
&& isOutOfBounds(getContext(), event) && getWindow().peekDecorView() != null)) {
hide();
}
return false;
}
private boolean isOutOfBounds(Context context, MotionEvent event) {
final int x = (int) event.getX();
final int y = (int) event.getY();
final int slop = ViewConfiguration.get(context).getScaledWindowTouchSlop();
final View decorView = getWindow().getDecorView();
return (x < -slop) || (y < -slop)
|| (x > (decorView.getWidth()+slop))
|| (y > (decorView.getHeight()+slop));
}
This solution doesnt have this problem :
This works great except that the activity underneath also reacts to the touch event. Is there some way to prevent this? – howettl
I tried some answers still I faced a problem like when I press outside the dialog dialog was hiding but a dimmed view was showing, and pressing again would go to the parent activity. But actually I wanted to go the parent activity after first click. So what I did was
dialog.setOnCancelListener(this);
and changed my activity to implement DialogInterface.OnCancelListener
with
@Override
public void onCancel(DialogInterface dialog) {
finish();
}
And boom, it worked.
Here is the code
dialog.getWindow().getDecorView().setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent ev) {
if(MotionEvent.ACTION_DOWN == ev.getAction())
{
Rect dialogBounds = new Rect();
dialog. getWindow().getDecorView().getHitRect(dialogBounds);
if (!dialogBounds.contains((int) ev.getX(), (int) ev.getY())) {
// You have clicked the grey area
UiUtils.hideKeyboard2(getActivity());
return false; // stop activity closing
}
}
getActivity().dispatchTouchEvent(ev);
return false;
}
});
Try this one . you can hide the keyboard when you touch outside
