I have the following code in my activity. In my xml, the video view is inside the linear layout. However, when the view is clicked, the onTouchListener never fires. I tried changing the onTouchListener to vvLive but that didn't do anything. I also tried changing the onTouchListener to an onClickListener, but nothing. Anyone know why the listener isn't firing? Thanks.

        private VideoView vvLive;
        LinearLayout linearLayoutLiveVideo;

        linearLayoutLiveVideo.setOnTouchListener(new OnTouchListener(){
            public boolean onTouch(View v, MotionEvent event){
                Log.d(TAG, "onTouch entered");
                if(event.getAction() == MotionEvent.ACTION_UP) {
                    Log.d(TAG, "ACTION_UP");

                }
                return false;
            }
        });

EDIT: I realized the code above actually works. Something in eclipse was messing up LogCat. After I restarted eclipse, LogCat prints the first log "onTouch entered". However, "ACTION_UP" was not being printed. I changed the MotionEvent to MotionEvent.ACTION_DOWN and the LogCat prints now. Why does ACTION_DOWN work but ACTION_UP does not?

ACTION_UP is never being sent to your listener because you return false and therefor don't "consume" the event. Return true and you'll get the start event (ACTION_DOWN) as well as all the subsequent ones (ACTION_MOVE and then ACTION_UP).
