Answer 1

you can find homeview in actionbarview define like this:

but you cannot get upView by findViewById(android.R.id.up).

so you can get homeView and get its parent view ,set upview width 0

    ImageView view = (ImageView)findViewById(android.R.id.home);
    if(view.getParent() instanceof ViewGroup){
        ViewGroup viewGroup = (ViewGroup)view.getParent();
        View upView = viewGroup.getChildAt(0);
        FrameLayout.LayoutParams layoutParams = (FrameLayout.LayoutParams) upView.getLayoutParams();
        layoutParams.width = 0;
        upView.setLayoutParams(layoutParams);
    }
