Android全屏活动错误

概述我正在尝试创建全屏活动：publicvoidonCreate(BundlesavedInstanceState){super.onCreate(savedInstanceState);requestWindowFeature(Window.FEATURE_NO_TITLE);getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,

我正在尝试创建全屏活动：

public voID onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        requestwindowFeature(Window.FEATURE_NO_Title);        getwindow().setFlags(WindowManager.LayoutParams.FLAG_FulLSCREEN,                WindowManager.LayoutParams.FLAG_FulLSCREEN);        setContentVIEw(R.layout.activity_main);   }

我收到以下错误：

requestFeature() must be called before adding content

解决方法:

将requestwindowFeature放在super.onCreate之前

public voID onCreate(Bundle savedInstanceState) {requestwindowFeature(Window.FEATURE_NO_Title);        super.onCreate(savedInstanceState);getwindow().setFlags(WindowManager.LayoutParams.FLAG_FulLSCREEN,WindowManager.LayoutParams.FLAG_FulLSCREEN);setContentVIEw(R.layout.activity_main);   }
