You will have to create Custom Title Bar Layout to add your own image in titlebar.And then you can use following code to assign the titlebar to your view

    boolean customTitleSupported;
    @Override
    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    customTitleSupported = requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
    if (customTitleSupported) {
        getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE,R.layout.custom_tittlebar_layout);         

        }
        setContentView(R.layout.main);
   }  

here custom_tittlebar_layout refers to your custom titlebar layout with image.
