It is not possible to hide the system bar. There is nothing in the API that allows for it. This is because the user always needs access to the home and back keys in case the app freezes or does something goofy where the user just needs to get out of the app. You can only hide the action bar.
无法隐藏系统栏。API 中没有任何内容允许这样做。这是因为用户总是需要访问 home 键和 back 键，以防应用程序冻结或在用户只需要退出应用程序的情况下做了一些愚蠢的事情。您只能隐藏操作栏。

There is a workaround to disable menu bar in all most all tablets without rooting. But this is bit tricky, but it works clean. Several well known apps in the market at the moment using this strategy to achieve this disable menu bar feature for their apps.
有一种解决方法可以在所有平板电脑中禁用菜单栏而无需生根。但这有点棘手，但它很干净。目前市场上的几个知名应用程序都使用这种策略来实现其应用程序的禁用菜单栏功能。
- Grant admin privilege.
- Set password & lock the device using device admin profile api
- Then load what ever the UIs on top of the native lock screen. (Of course this will show background lock screen whenever a transition happens between activities. But if logic is organized well, then it will be smooth & less noticed by the user)
- When need to enable back, reset password to "" using resetPassword("", 0) of device policy manager object.
- 授予管理员权限。
- 使用设备管理员配置文件 api 设置密码并锁定设备
- 然后在本机锁定屏幕顶部加载任何 UI。（当然，每当活动之间发生转换时，这都会显示背景锁定屏幕。但是如果逻辑组织得很好，那么它会很流畅并且不会被用户注意到）
- 当需要启用返回时，使用设备策略管理器对象的 resetPassword("", 0) 将密码重置为 ""。

You just need combination of SYSTEM_UI_FLAG_IMMERSIVE_STICKY | SYSTEM_UI_FLAG_HIDE_NAVIGATION | SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN. For example, if you use opengl and glSurfaceView is you surface:
你只需要 SYSTEM_UI_FLAG_IMMERSIVE_STICKY | 的组合 SYSTEM_UI_FLAG_HIDE_NAVIGATION | SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN。例如，如果您使用 opengl 和 glSurfaceView 是您的表面：
glSurfaceView.setSystemUiVisibility(
View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY |
View.SYSTEM_UI_FLAG_HIDE_NAVIGATION |
View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
Swipe at bottom to see the bottom bar, it will hide again after few seconds.
在底部滑动以查看底部栏，几秒钟后它会再次隐藏。

You can't hide it but you can simply disable it, except home. Try this link.. Using SYSTEM_UI_FLAG_LOW_PROFILE you can dim your system bar and using onWindowFocusChanged()can take the focus and collapse it.
你不能隐藏它，但你可以简单地禁用它，除了家。试试这个链接。. 使用 SYSTEM_UI_FLAG_LOW_PROFILE 您可以使系统栏变暗，使用onWindowFocusChanged()可以获取焦点并将其折叠。

I believe its the same for all android devices.
我相信它对所有 android 设备都是一样的。
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
I also found another solution but this of course is just a separate app called surelock.
我还找到了另一个解决方案，但这当然只是一个名为surelock的单独应用程序。

I found a trick on a galaxy tab for use it as a kiosk according to the developer guide of Samsung
根据三星的开发人员指南，我在星系标签上找到了一个技巧，将其用作信息亭
You can ask your app to be over the lock system and ask the return button to go back to a start activity/view of your app. I done this for a web View app
您可以要求您的应用程序越过锁定系统，并要求返回按钮返回到您的应用程序的开始活动/视图。我为 Web View 应用程序完成了此操作
@Override
public void onBackPressed() {
//here asking to go back to home page
mWebView.loadUrl(mHomepageUrl);
}
for asking to stay up from the lock system, on the onCreate method :
在 onCreate 方法上要求保持锁定系统：
getWindow().addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
and then when you click on the power button twice , you found back your application , and only the back button is active on the status bar
然后当您单击电源按钮两次时，您会找到您的应用程序，并且状态栏上只有后退按钮处于活动状态
So the only way is to reboot the tablet (and so you can use the classic lock system with a code to open tablet)
所以唯一的方法是重启平板电脑（这样你就可以使用带有密码的经典锁定系统来打开平板电脑）
Can be useful if the power button is not accible by visitor , or if your are the only one who have the unlock code
如果访问者无法使用电源按钮，或者您是唯一拥有解锁码的人，则此功能很有用

// Put code on onCreate method of your activity / fragment
// 将代码放在您的活动/片段的 onCreate 方法上
@Override
@SuppressLint("NewApi")
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getSupportActionBar().hide();
setContentView(R.layout.activity_main);
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
}
