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

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

Android 实现画面全屏（取消标题、取消状态栏），写的代码如下：

//取消标题
requestWindowFeature(Window.FEATURE_NO_TITLE);
//取消状态栏
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_photo_album_detail);

刚开始运行的时候没问题。后来其他地方改了代码，再跳转到这个activity就出现了上面的异常。
后来发现了这个，试了下，问题解决了：

//取消标题
supportRequestWindowFeature(Window.FEATURE_NO_TITLE); //继承AppCompatActivity中使用
// requestWindowFeature(Window.FEATURE_NO_TITLE); //继承Activity 中使用
//取消状态栏
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_photo_album_detail);这个activity继承的是AppCompatActivity。
