How to listen onTouch and onClick event simultaneously?

Question

I have a button and a text label displaying a number. I want to click the button to add the number of the label to the button. I want to also enable holding on the button for a while and later start to add the number continuously. If the longclick event has added the number, the click event will do nothing. How can I implement this?

Use a custom TouchListener like this (this is very basic, written in the browser, not in an IDE):

boolean touching = false;
long startTime = 0;

@Override
public boolean onTouchEvent(MotionEvent e) {

switch (e.getAction()) {
    case MotionEvent.ACTION_DOWN:
    if(touching){
        onLongClick(System.currentTimeMillis() - startTime)
    }else{
        touching = true;
        startTime = System.currentTimeMillis;
        onClick();
    }
    break;

    case MotionEvent.ACTION_UP:
    case MotionEvent.ACTION_CANCEL:
       touching = false;
    break;
   }
return true;
}

onLongClick(long elapsedTime){
//Do stuff
}
