How to dismiss your non-modal dialog, when touched outside dialog region

When you implement your dialog as non-modal dialog, means when your dialog is shown, you can interact with other elements on the screen, in such case, you might be interested to dismiss the dialog, when user touches/press/interacts with other elments on the screen. The following steps will help you to reeceive for the touch events outside your non-modal dialog.

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.

 public boolean onTouchEvent(MotionEvent event)
 {
  
        if(event.getAction() == MotionEvent.ACTION_OUTSIDE){
         System.out.println("TOuch outside the dialog ******************** ");
                this.dismiss();
        }
        return false;
 }
