How to dismiss the dialog with click on outside of the dialog?

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?

Solution 1:

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;  
}

Solution 2:

Simply use

dialog.setCanceledOnTouchOutside(true);

Solution 3:

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 );
}

Solution 4:

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>

Solution 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);
