    }

    //自定义的顶部ActionBar的点击监听；

    private  HomeToolbarClickListener listener;

    //点击事件的监听接口

    public interface HomeToolbarClickListener {

         void leftClick();

         void rightClick();

    }

    //提供activity调用的方法，类似于Button类的setOnClickListener(OnClickListener listener)

    //传入具体实现方法

    public void setOnTopbarClickListener(HomeToolbarClickListener listener){

        this.listener=listener;

    }

}
