Answer 1

versuchen, wie diese

private static final int MIN_CLICK_DURATION = 600; 
private long startClickTime; 
private boolean longClickActive; 

your_view.setOnTouchListener(new View.OnTouchListener() { 
    @Override 
    public boolean onTouch(View v, MotionEvent event) { 

     switch (event.getAction()) { 
     case MotionEvent.ACTION_DOWN: 

       if (longClickActive == false) { 
           longClickActive = true; 
           startClickTime = Calendar.getInstance().getTimeInMillis(); 
          } 
      break; 

     case MotionEvent.ACTION_UP: 

      if (longClickActive == true) { 
           long clickDuration = Calendar.getInstance().getTimeInMillis() - startClickTime; 
           if (clickDuration >= MIN_CLICK_DURATION) { 
            longClickActive = false; 
            // long click detected here 
           } 
      } 

      break; 
     case MotionEvent.ACTION_UP: 

      longClickActive = false; 

      break; 
     default: 
      break; 
     } 
     return true; 
    } 

});
