Activity代码设置全屏显示

通过代码来设置Activity的全屏显示，代码如下：

1     protected void onCreate(Bundle savedInstanceState) {
2         super.onCreate(savedInstanceState);
3         requestWindowFeature(Window.FEATURE_NO_TITLE); // 去除标题  必须在setContentView()方法之前调用
4         setContentView(R.layout.activity_main);
5         getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); // 设置全屏
6         surfaceview = (SurfaceView) findViewById(R.id.surfaceview);
7     }
