Android 滑动菜单打开或关闭时运行方法

我正在使用Jeremy Feinstein的Android滑动菜单，当滑动菜单打开和/或关闭时，我需要帮助运行一个方法。我想根据菜单的状态更改图标。我尝试将SlidingMenu子类化并覆盖切换方法，如下所示：

public class SlidingMenuCustom extends SlidingMenu {

ImageView plus;

public SlidingMenuCustom(Activity activity, ImageView plus) {
    super(activity);
    this.plus = plus;
}

@Override
public void toggle(){
    super.toggle();
    Log.d("Hello", Global.debug + " " + isMenuShowing());
    if(isMenuShowing()){
        plus.setImageResource(R.drawable.sidenavminus);
    }else{
        plus.setImageResource(R.drawable.sidenavplus);
    }


}

}

但后来我意识到，只有在我调用它时才会调用切换，所以这是行不通的。当滑动菜单打开或关闭时，我是否可以执行其他操作来运行方法

1.打开滑动菜单侦听器

     slidingmenu.setOnOpenedListener(new OnOpenedListener() {

        @Override
        public void onOpened() {
               //execute your code
        }

    });

     slidingmenu.setOnClosedListener(new OnOpenedListener() {

        @Override
        public void onClosed() {
               //execute your code
         }

    });

1.关闭滑动菜单侦听器

     slidingmenu.setOnOpenedListener(new OnOpenedListener() {

        @Override
        public void onOpened() {
               //execute your code
        }

    });

     slidingmenu.setOnClosedListener(new OnOpenedListener() {

        @Override
        public void onClosed() {
               //execute your code
         }

    });
