如何显示在Android的导航抽屉的活动(登录屏幕)抽屉、屏幕、Android

2023-09-04 07:00:25 作者:污男i

基本上我的要求是采用滑出​​导航,如Facebook滑出菜单显示一个登录界面给用户。

Basically my requirement is to show a login screen to the user using the sliding out navigation like Facebook slide out menu.

我想在Android开发者网站上只显示使用列表视图导航抽屉的例子。任何一个可以请告诉我有没有可能用抽屉式导航栏显示一个活动呢?

I tried the navigation drawer example available on android developers website it shows only using list view. Can any one tell me please is it possible to show a activity using navigation drawer?

请参见下图:

可以任何一个,请帮我摆脱这个?

could any one please help me to get rid of this?

在主要活动

你必须处理公开和放大器;关闭抽屉

编辑29/12/13:

是的,你可以不用动作条。

Yes you can do it without actionbar.

我刚刚加入这一行 getActionBar()隐藏(); 在的onCreate()在MainActivity结束

i have just add this line getActionBar().hide(); at end of onCreate() in MainActivity.
