1 – Set the flag-FLAG_NOT_TOUCH_MODALfor 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;  
}  

I have a dialog that I want to be dismissed when I click outside it. However, I don’t want it to receive key events, because it’s a volume dialog, and I want the activity to be able to receive the key volume up and down events. So I setted FLAG_NOT_FOCUSABLE, as you see below:

    AlertDialog.Builder builder = new AlertDialog.Builder(context, R.style.MyDialogTheme);
    AlertDialog alert = builder.create();
    Window window = alert.getWindow();
    window.setFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE, WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);
    alert.setView(view);

the problem is that, with this flag, I also can’t make the dialog dismiss when a touch outside it happens.

All the solutions on How to dismiss the dialog with click on outside of the dialog? like dialog.setCanceledOnTouchOutside(true); wont work in this case.
