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：

　

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