Question

I want my activity (a normal activity with a digital clock at the center of it) to close when I tap it anywhere. Is there a sort of Activity.setOnClickListener or a way to do it?

Answer 1

Yes on an Activity you override the existing handlers, on controls you add touch listeners, and [activityinstance].finish() gracefully closes your app.

@Override
public boolean onTouchEvent(MotionEvent event) {
    this.finish();
    return true;
}
