    </RelativeLayout> 

setOnClickListener

findViewById(R.id.giftAppBgImage).setOnClickListener(this); 

@Override 
    public void onClick(final View v) { 
     // TODO AK-generated method stub 
     showLog("catch onClick event!" + v.getClass().getName()); 
     if (v instanceof ImageView) { 
      ((ImageView) v).setImageResource(R.drawable.cell_bg_hover); 
      Animation anim = AnimationUtils.loadAnimation(getActivity(), R.anim.more_animation); 
      anim.setAnimationListener(new AnimationListener() { 

       @Override 
       public void onAnimationStart(Animation arg0) { 
        // TODO AK-generated method stub 

       } 

       @Override 
       public void onAnimationRepeat(Animation arg0) {

       } 

       @Override 
       public void onAnimationEnd(Animation arg0) { 
        // TODO AK-generated method stub 
        ((ImageView) v).setImageResource(R.drawable.cell_bg); 
       } 
      }); 
      v.startAnimation(anim); 

     } 
    }
