              getActionBar().setHomeButtonEnabled(false);
              getActionBar().setDisplayShowTitleEnabled(false);
              getActionBar().setDisplayShowCustomEnabled(true);
              getActionBar().setIcon(new ColorDrawable(getResources().getColor(android.R.color.transparent)));
              getActionBar().setCustomView(v);
  
              View v1 = getActionBar().getCustomView();
              LayoutParams lp = (LayoutParams) v1.getLayoutParams();
