關閉鍵盤后導航欄不會隱藏

Question

當我填寫輸入字段並關閉鍵盤時，我的導航欄將不會隱藏。

在我填寫輸入字段之前，它是隱藏的。

我嘗試了多種解決方案，但沒有一種適合我。

this.Window.AddFlags(WindowManagerFlags.Fullscreen); // hide the status bar

int uiOptions = (int)Window.DecorView.SystemUiVisibility;

uiOptions |= (int)SystemUiFlags.LowProfile;
uiOptions |= (int)SystemUiFlags.Fullscreen;
uiOptions |= (int)SystemUiFlags.HideNavigation;
uiOptions |= (int)SystemUiFlags.ImmersiveSticky;

Window.DecorView.SystemUiVisibility = (StatusBarVisibility)uiOptions;

這是我MainActivity OnCreate方法中的代碼。

這是演示。

實現View.IOnSystemUiVisibilityChangeListener接口：

    public void OnSystemUiVisibilityChange([GeneratedEnum] StatusBarVisibility visibility)
    {
        if (((int)visibility & (int)SystemUiFlags.Fullscreen) == 0)
        {
            Window.DecorView.SystemUiVisibility = (StatusBarVisibility)uiOptions;
        }

    }

為您的DecorView添加偵聽器：

Window.DecorView.SetOnSystemUiVisibilityChangeListener(this);

覆蓋OnWindowFocusChanged ：

    public override void OnWindowFocusChanged(bool hasFocus)
    {
        base.OnWindowFocusChanged(hasFocus);
        Window.DecorView.SystemUiVisibility = (StatusBarVisibility)((int)SystemUiFlags.Fullscreen
            | (int)SystemUiFlags.ImmersiveSticky
            | (int)SystemUiFlags.LayoutHideNavigation
            | (int)SystemUiFlags.LayoutStable
            | (int)SystemUiFlags.HideNavigation);
    }
