Detect Motion Event On Screen

When I was working on analytics for Kinetic, the click event in setOnClickListener never gets called. So I find out a secondary solution is to catch up the screen motion event in Activity.

Override the following function:

@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
	  // Touch event catched.
    return super.dispatchTouchEvent(ev);
}

There is one problem with this touch event is that it will called on any kinds of motions. For example, you scroll the view. What if I only when user click on the screen?
