Question

I have a seemingly simple question that I need help with. I have a button. I want it so when I click on the button quickly it adds one to a total. I also want it to be so that when I hold down this same button for about 2 seconds, it removes one from the total. The only part I am having trouble with is the motion event part. I have been experimenting with ACTION_UP and ACTION_DOWN with no luck. Is there an easy way to do this?

switch (event.getAction())
       {    
           case MotionEvent.ACTION_DOWN:
           {
               total ++;
               return true;
           }

           case MotionEvent.ACTION_UP:
           {
               if(total >0){
                total--;
               }
               return true;
           }
        }

Thanks for the help!

Why not use the Button’s setOnClickListener and setOnLongClickListener?

The only limitation with this approach is that you cannot set the the timeout value, which is somewhat over 1,5 seconds, if I remember correctly.

If you’re persistent about the two seconds (or some other value), then I suppose you could use an onTouchListener and keep track of the pressed time yourself. In that case, the MotionEvent’s getDownTime might be of interest to you.
