Button.setOnTouchListener(new OnTouchListener(){
  public boolean onTouch(View v, MotionEvent event){
    if(event.getAction()==MotionEvent.ACTION_DOWN){
      v.setPadding(10,10,10,10);
      v.setAlpha(0.55f);
    }else if(event.getAction()==MotionEvent.ACTION_UP){
      V.setPadding(0,0,0,0);
      v.setAlpha(1.0f);
      //* 여기에 버튼 기능 넣으면 됨
    }
  }
  
});
