Question

基本上我的要求是使用像Facebook滑出菜单这样的滑出导航向用户显示登录屏幕。

我尝试了Android开发者网站上提供的导航抽屉示例，它仅使用列表视图显示。任何人都可以告诉我，是否可以使用导航抽屉显示活动？

请看下图：

任何人都可以帮我摆脱这个吗？

我已编辑Navigation Drawer示例下载它。改变它的方式。

         this as a sliding drawer on the left side for left-to-right
         languages and on the right side for right-to-left languages.
         The drawer is given a fixed width in dp and extends the full height of
         the container. A solid background is used for contrast
         with the content view.

LeftFragment.java

public class LeftFragment extends Fragment {

    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

    }

    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);

    }

}

activity_login.xml - ＆gt;做任何你想要的设计。

你必须处理open＆amp;关闭抽屉

2013年12月29日编辑：

是的，你可以在没有操作栏的情况下完成。

我刚刚在MainActivity中的onCreate（）末尾添加了这一行getActionBar().hide();。

您必须使用幻灯片（滑动）打开登录页面

Answer 2

抽屉的Android小部件 - ＆gt; SlidingDrawer但是你不能仅将它用于一项活动。我更喜欢的方法是使用片段。
