Activity全屏和去掉标题拦

参考下面代码

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//设置不显示标题拦
requestWindowFeature(Window.FEATURE_NO_TITLE);
//设置全屏
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
//横屏显示：也可以在AndroidManifest.xml的activity标签中配置
//android:screenOrientation="landscape"属性
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
//以上代码一定要写在setContentView(R.layout.main)之前
setContentView(R.layout.main)
