如何在Android LockScreen应用程序中禁用导航栏，例如CM储物柜和OS8锁定屏幕 [英] How to disable naviagation bar in Android LockScreen App like CM locker and OS8 lock screen

问题描述

我尝试设置systemUIView(View.GONE)并使用沉浸式全屏模式.但是，用户始终可以通过触摸屏幕底部来返回导航栏.我上面提到的应用程序可以隐藏它，而无需root用户或设置默认启动器.

I tried setting systemUIView(View.GONE) and use Immersive Full-Screen Mode. But users can always get the naviagtion bar back by touching the bottom of the screen. The apps i mentioned above are able to hide it without root or setting default launcher.

推荐答案

好的，我终于找到了解决方案，这是完成的过程:

Okay, I found a solution finally and here is how it's done:

1. 使用SYSTEM_UI_FLAG_IMMERSIVE_STICKY隐藏导航栏，如下所示，您可以将代码放在活动的onResume中

1. Use SYSTEM_UI_FLAG_IMMERSIVE_STICKY to hide the navigation bar as follow, you may put the code inside onResume of your activity

查看decorView = getWindow().getDecorView(); int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY; decorView.setSystemUiVisibility(uiOptions);

View decorView = getWindow().getDecorView(); int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION |View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY; decorView.setSystemUiVisibility(uiOptions);

然后，使用WindowManger添加系统错误窗口并将其覆盖在所有内容之上

Then, add a system error window using WindowManger and overlay it on top of everything

您可以将这个无法逃避的视图放置在您喜欢的任何位置，但是如果您想在用户锁定屏幕时执行此操作，请添加以下标志:

you can put this unescapable view anywhere you like, but if you want to do it while users locked the screen, add this flag:

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

Etvoilà
