My app is a single activity with Theme.Holo.Dialog. In my case the other answer did not work. It only made the other background apps or the launch screen to receive touch events.

I found that using dispatchTouchEvent works in my case. I think it is also a simpler solution. Here's some sample code on how to use it to detect taps outside the activity with a Dialog theme:

@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
    Rect dialogBounds = new Rect();
    getWindow().getDecorView().getHitRect(dialogBounds);

    if (!dialogBounds.contains((int) ev.getX(), (int) ev.getY())) {
        // Tapped outside so we finish the activity
        this.finish();
    }
    return super.dispatchTouchEvent(ev);
}
