how to change colour of action bar tabs on click for a few seconds only in android

I am using action bar tabs(not tabhost) . I want to change colour of my selected tab for a second (like whtsapp). I have used this code but its not working and this code is also hiding my tabs text.

public void onTabSelected(Tab tab, FragmentTransaction ft)
{
   TextView v=new TextView(TabActivity.this);
   Log.d("TextView", v.toString());
   v.setBackgroundColor(Color.GREEN);  
   tab.setCustomView(v);
}
