Android编程实现播放视频时切换全屏并隐藏状态栏的方法

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (this.getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) {
getWindow().getDecorView().setSystemUiVisibility(View.INVISIBLE); 
}
else if (this.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) {
// this.requestWindowFeature(Window.f);// 去掉标题栏
// this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
// WindowManager.LayoutParams.FLAG_FULLSCREEN);// 去掉信息栏
Log.i("info", "portrait"); // 竖屏
}

<uses-sdk android:minSdkVersion="11" />

if (this.getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) {
  WindowManager.LayoutParams attrs = getWindow().getAttributes();
  attrs.flags |= WindowManager.LayoutParams.FLAG_FULLSCREEN;
  getWindow().setAttributes(attrs);
  getWindow().addFlags(
      WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
} else if (this.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) {
  WindowManager.LayoutParams attrs = getWindow().getAttributes();
  attrs.flags &= (~WindowManager.LayoutParams.FLAG_FULLSCREEN);
  getWindow().setAttributes(attrs);
  getWindow().clearFlags(
      WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
}
