How to dismiss the dialog with click on outside of

Question

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?

Answer 1

Or, if you're customizing the dialog using a theme defined in your style xml, put this line in your theme:

<item name="android:windowCloseOnTouchOutside">true</item>

Answer 2

Another solution this code was cutted from android source code of Window You should just add this 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

Answer 3

Call dialog.setCancelable(false); from your activity/fragment.

Answer 4

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;  
}

Answer 5

dialog.setCanceledOnTouchOutside(true); 

to close dialog on touch outside.

And if you don't want to close on touch outside, use the code below:

dialog.setCanceledOnTouchOutside(false);

Answer 6

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 );
}
