View customNav = LayoutInflater.from(this).inflate(R.layout.activity_custom_layout, null);     
actionBar.setCustomView(customNav); 
actionBar.setDisplayShowCustomEnabled(true); 
final Context context1 = this; 
ImageButton ibItem1 = (ImageButton) customNav.findViewById(R.id.refresh); 
ibItem1.setPadding(280, 0, 0, 0); 
ibItem1.setVisibility(View.INVISIBLE); 
ibItem1.setOnClickListener(new View.OnClickListener() 
{ @Override public void onClick(View view) { } });

试试这个样本...

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    View contentView = getLayoutInflater().inflate(R.layout.test_layout, null);
    setContentView(contentView);
    LinearLayout layout = (LinearLayout) contentView.getParent()
            .getParent();
    View view = layout.getChildAt(0);
    ViewGroup actionBarView = (ViewGroup) view;
    LinearLayout.LayoutParams layoutParams = (android.widget.LinearLayout.LayoutParams) actionBarView
            .getLayoutParams();
    layoutParams.width = 200;
    layoutParams.gravity = Gravity.CENTER;
    actionBarView.setLayoutParams(layoutParams);
}
