java - 安卓 : is it possible to call requestFeature() after setContentView ?

Question

我想在使用 setContentView() 加载 View 后调用 requestFeature()，但错误非常明显:

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

没有办法直接在 Activity 中调用 requestFeature() 吗？

Answer 1

来自开发者网站关于 requestFeature() :

Enable extended screen features. This must be called before setContentView(). May be called as many times as desired as long as it is before setContentView(). If not called, no extended features will be available. You can not turn off a feature once it is requested. You canot use other title features with FEATURE_CUSTOM_TITLE.

所以简单的答案是否定的。
