private float x1,x2; 
static final int DISTANCE = 100; 

und setOnTouchListener auf den Knopf. und dann außer Kraft setzen onTouchEvent:

@Override 
public boolean onTouchEvent(MotionEvent event) 
{  
switch(event.getAction()) 
{ 
    case MotionEvent.ACTION_DOWN: 
     x1 = event.getX();       
    break;   
    case MotionEvent.ACTION_UP: 
     x2 = event.getX(); 
     float deltaX = x2 - x1; 
     if (Math.abs(deltaX) > MIN_DISTANCE){ 
      findViewById(R.id.recent_layout).setVisibility(View.GONE); 
     }       
    break; 
}   
return super.onTouchEvent(event);  
}
