变化方向
我开发的应用程序用于显示频道的直播流，并将其默认启动景观模式，我可以从我的选项菜单布局被打破，在Android的
现在我使用更改为纵向，反之亦然这个代码在清单，并把它在该活动中 android：configChanges =“keyboard | keyboardHidden | orientation | screenSize”
当我启动的应用程序，它工作正常，但当我改变方向肖像，应用程序挂起选项菜单不会照常消失。
如果我从清单中删除了这部分|screenSize，它工作正常，但布局土地不起作用，并且在两个方向都使用纵向布局。
这是LiveActivity.java

因为我从景观转换为肖像，反之亦然动态从选项菜单 – 2013-03-11 06:16:39
所以我认为你必须setContentView（R.layout.portrait）;动态onclick。 – 2013-03-11 06:22:13
