/ / Initialize PopupWindow 
popupWindow = new PopupWindow (gridView, LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT, true); 
popupWindow.setBackgroundDrawable (new BitmapDrawable ());

tabWidget.getChildAt (4). setOnClickListener (new View.OnClickListener () 
{

@ Override 
public void onClick (View v) 
{

} 
}); 
}
