Android开发经验一判断当前屏幕是全屏还是非全屏

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);




        int v = this.getWindow().getAttributes().flags;
        // 全屏 66816 - 非全屏 65792
        if(v != 66816){//非全屏
            this.getWindow().setFlags(
                    WindowManager.LayoutParams.FLAG_FULLSCREEN,
                    WindowManager.LayoutParams.FLAG_FULLSCREEN);
        }else{//取消全屏
            this.getWindow().clearFlags(
                    WindowManager.LayoutParams.FLAG_FULLSCREEN);
        }

    }
