我想选择在多个活动中使用navigationDrawer 的方法，该方法使用一个承载NavDrawerl 布局和初始化的AbstractActivity，而我继承的活动只是将布局设置为drawerLayout 的内容。一切正常，抽屉随处可见。单击一个列表项应该会开始一个新的活动。

我选择尝试这个，因为我不想要一个单一的活动，而不是托管 10k 行代码来实现我所有的进程间通信和后台服务的东西。一切正常。除了抽屉确实在我新开始的活动中关闭。这不好，因为通常如果您从列表中选择某些内容，它会很好地滑回。我想找到一个折衷方案，只是为新活动的结束设置动画，这不会有太大的不同。但我无法让它工作，因为我所有的电话

        return super.onOptionsItemSelected(item);
    }
}


public class OneActivity extends AbstractNavDrawerActivity {

    @Override
    protected View getContentView() {
        return getLayoutInflater().inflate(R.layout.ac_one, null);
    }

有没有人知道我们如何才能让它看起来“酷”。我认为这对于复杂的应用程序来说是一个很好的解决方案。我不喜欢 One Activity 1943209483280 Fragment Action Listener 方法。
