Is is possible to force an app to always show to navigation bar in an Android app? On Samsung Galaxy S8 it is possible for the user to hide the navbar during "runtime" - which cause some unexpected behaviours in the app (if you are interested; I tried to add a setOnSystemUiVisibilityChangeListener and redraw, invalidate, requestLayout and forceLayout on the view with no luck. Restarting the activity is not applicable as the app is a single-activity-app. I've also looked into WindowInsets with no luck there neither.).

Therefor, I just want to avoid the problem by not allowing the user to remove the navbar. All the resources I can find online is for hiding the navbar. Does anybody how any suggestions on how to make it stay?

我不太确定三星 S8，但我曾在三星 S7 上工作过。我使用了后仰模式 setSystemUiVisibility()并通过了这两个标志

1. SYSTEM_UI_FLAG_FULLSCREEN
2.SYSTEM_UI_FLAG_HIDE_NAVIGATION
也是为了启用沉浸式模式，我曾经SYSTEM_UI_FLAG_IMMERSIVE结合使用过。

它是从可见性和 沉浸式中引用的。

如果我错了或者我不明白这个问题，请纠正我。

这对我有用：

        getWindow().getDecorView().setSystemUiVisibility(
            View.SYSTEM_UI_FLAG_IMMERSIVE
                    | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
                    | View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                    | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                    | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION);
