Android Eclipse 应用程序在启动时崩溃

我是 Android 开发新手，在启动项目时遇到问题。每当我启动它时，它就会崩溃

以下是 LogCat 的输出:

这是我的 AndroidManifest.xml，如果您需要的话:

logcat 说:

Caused by: android.util.AndroidRuntimeException: requestFeature() must be called before adding content

换句话说，您在 Activity 中调用 setContentView() 后才调用 requestFeature()。但这是不可能的。您必须在调用 setContentView() 之前调用 requestFeature()。您还没有发布任何代码，所以我无法给您更具体的答案。
