android - 自上而下滑动时阻止状态栏

Question

我有一个覆盖整个屏幕的全屏应用程序，包括顶部状态栏。由于启用了向上/向下滑动以向用户显示一些选项，因此从上到下滑动会显示状态栏(当您想查看通知并从上向下滑动时) .有没有办法避免这种情况？

为 WindowManager.LayoutParams 使用类型 TYPE_SYSTEM_ERROR，以创建隐藏不可能的全屏 View 。显示状态栏和导航的滑动将被阻止。

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    mMainLayout = (RelativeLayout) LayoutInflater.from(this).inflate(R.layout.activity_fullscreen, null);

    requestWindowFeature(Window.FEATURE_NO_TITLE);

    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

    WindowManager.LayoutParams handleParams = new WindowManager.LayoutParams(
        WindowManager.LayoutParams.MATCH_PARENT,
        WindowManager.LayoutParams.MATCH_PARENT,
        WindowManager.LayoutParams.TYPE_SYSTEM_ERROR,
        WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE |
            WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |
            WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN,
        PixelFormat.TRANSLUCENT);
    handleParams.gravity = Gravity.TOP;

    WindowManager windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
    windowManager.addView(mMainLayout, handleParams);
}

如果需要，您应该在显示器开机(解锁屏幕)后显示它。添加代码:

getWindow().addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
