永久隐藏 Android 状态栏

Question

提问by dtyler

I'm trying to hide the system Status Bar on an Android 4.4 device. This is for a kiosk-mode where my app will be the only app ever run on the device. The target device for now is a 2013 Nexus 7.

我正在尝试在 Android 4.4 设备上隐藏系统状态栏。这适用于自助服务终端模式，在这种模式下，我的应用将是设备上唯一运行的应用。目前的目标设备是 2013 Nexus 7。

The device is rooted, and I've been able to completely remove the bottom Navigation Bar with some info from this post.

该设备已植根，我已经能够完全删除底部导航栏和这篇文章中的一些信息。

For the top Status Bar, everything I have tried only hides the bar temporarily. If my users motion down at the top of the screen, the status bar reappears. I don't want to allow them to see the time, get to settings or even see notifications.

对于顶部状态栏，我尝试过的一切只是暂时隐藏了状态栏。如果我的用户在屏幕顶部向下移动，状态栏会重新出现。我不想让他们看到时间、进入设置甚至看到通知。

Posts I've found and already tried:

我发现并已经尝试过的帖子：

Any suggestions?

有什么建议？

Ideally, I'd love to be able to edit build.prop to do this, since I'm already doing that for the navigation bar, and could do this at the same time. I'm trying to not have to build my own android image.

理想情况下，我希望能够编辑 build.prop 来执行此操作，因为我已经在为导航栏执行此操作，并且可以同时执行此操作。我正在尝试不必构建自己的 android 映像。

Update:

更新：

After some more work, this seems to depend somewhat on the exact build of android, or the device its running on.

经过一些更多的工作，这似乎在某种程度上取决于 android 的确切构建，或其运行的设备。

Some devices, such as the Nexus series I've been working with allow the user to swipe to make the bar reappear.

某些设备，例如我一直在使用的 Nexus 系列，允许用户滑动以使栏重新出现。

However, I've recently tried this on a Verizon Eclipse, and the bar does not reappear, which is what I was looking for.

但是，我最近在 Verizon Eclipse 上尝试了此操作，并且该栏没有重新出现，这正是我想要的。

I'm still looking for a better solution to target all devices, but it will probably come down to creating my own build of android.

我仍在寻找针对所有设备的更好解决方案，但它可能会归结为创建我自己的 android 版本。

We could not prevent the status appearing in full screen mode in kitkat devices, so made a hack which still suits the requirement ie block the status bar from expanding.

我们无法阻止在 kitkat 设备中以全屏模式显示状态，所以做了一个仍然符合要求的 hack，即阻止状态栏扩展。

For that to work, the app was not made full screen. We put a overlay over status bar and consumed all input events. It prevented the status from expanding.

为此，该应用程序并未全屏显示。我们在状态栏上放置了一个覆盖层并消耗了所有输入事件。它阻止了地位的扩大。

note:

笔记：

customViewGroup is custom class which extends any layout(frame,relative layout etc) and consumes touch event.
to consume touch event override the onInterceptTouchEvent method of the view group and return true

customViewGroup 是自定义类，它扩展任何布局（框架、相对布局等）并使用触摸事件。
消费触摸事件覆盖视图组的onInterceptTouchEvent方法并返回true

Updated

更新

<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>

customViewGroup implementationCode :

customViewGroup 实现代码：

WindowManager manager = ((WindowManager) getApplicationContext()
            .getSystemService(Context.WINDOW_SERVICE));

WindowManager.LayoutParams localLayoutParams = new WindowManager.LayoutParams();
localLayoutParams.type = WindowManager.LayoutParams.TYPE_SYSTEM_ERROR;
localLayoutParams.gravity = Gravity.TOP;
localLayoutParams.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE|

            // this is to enable the notification to recieve touch events
            WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |

            // Draws over status bar
            WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN;

    localLayoutParams.width = WindowManager.LayoutParams.MATCH_PARENT;
    localLayoutParams.height = (int) (50 * getResources()
            .getDisplayMetrics().scaledDensity);
    localLayoutParams.format = PixelFormat.TRANSPARENT;

    customViewGroup view = new customViewGroup(this);

    manager.addView(view, localLayoutParams);

Hope this helps you

希望这对你有帮助

I know this is an old question but hopefully it will help someone. Here are two very simple calls to disable and enable the status bar that I have used before. Can be used from the command line or executed by a Java app:

我知道这是一个老问题，但希望它会帮助某人。这里有两个非常简单的调用来禁用和启用我之前使用过的状态栏。可以从命令行使用或由 Java 应用程序执行：

Disable:

禁用：

service call activity 42 s16 com.android.systemui

Enable:

使能够：

am startservice -n com.android.systemui/.SystemUIService

I did try the workaround provided by @gonglong, but I wasn't happy with the result because of a flash in the UI as the workaround kicked in.

我确实尝试了@gonglong 提供的解决方法，但我对结果并不满意，因为该解决方法开始时 UI 中出现了闪光。

Instead, I was able to do this as root:

相反，我能够以 root 身份执行此操作：

settings put secure user_setup_complete 0

I think on a normal device, this would cause the initial device setup to start, but on my devices, I've removed that APK from system so that doesn't happen.

我认为在普通设备上，这会导致初始设备设置开始，但在我的设备上，我已从系统中删除了该 APK，因此不会发生这种情况。

This isn't documented anywhere I can find, but has a nice effect, where the top settings UI can't be dragged down. The notifications area can still be dragged down.

这在我能找到的任何地方都没有记录，但有一个很好的效果，顶部设置 UI 不能被拖下。通知区域仍然可以向下拖动。

Another setting that I found useful was:

我发现有用的另一个设置是：

settings put global device_provisioned 0

This hides the Airplane Mode and Silent Mode options from the Power menu, which is an added bonus for my application.

这隐藏了电源菜单中的飞行模式和静音模式选项，这对我的应用程序来说是一个额外的好处。

There might be more side effects, but I've yet to find any that matter to me.

可能会有更多的副作用，但我还没有发现任何对我来说很重要的副作用。

And for disabling the StatusBar (this may harm your device so do it carfully. I've ruined my device several times before I managed to do it) Tested on Asus Tinker Board, Android 6:

对于禁用状态栏（这可能会损坏您的设备，所以请小心操作。在我设法做到之前，我已经损坏了我的设备好几次）在 Asus Tinker Board，Android 6 上测试：

Download apktool from here https://bitbucket.org/iBotPeaches/apktool/downloads/and add it to pathin your favorite way
pull SystemUI.apkfrom your device: adb pull /system/priv-app/SystemUI/SystemUI.apkthe path to SystemUI.apkmay be different
pull framework-res.apkfrom your device adb pull /system/framework/framework-res.apkthe path to framework-res.apkmay be different
run apktool if framework-res.apk
run apktool if SystemUI.apk
run apktool d SystemUI.apk
Open SystemUI\res\layout\status_bar.xmland add android:visibility="gone"to the top most xml element (for me it was com.android.systemui.statusbar.phone.PhoneStatusBarView)
run apktool b SystemUI
Go to SystemUI\originaland copy AndroidManifest.xmland META-INFto SystemUI\build\apk\
run apktool b SystemUIagain
Go to SystemUI\dist\and override the device's original SystemUI.apkwith the one at SystemUI\dist\SystemUI.apkwith adb push SystemUI\dist\SystemUI.apk /system/priv-app/SystemUI/SystemUI.apk
Restart device

从这里下载 apktool https://bitbucket.org/iBotPeaches/apktool/downloads/并以path您喜欢的方式添加到
SystemUI.apk从您的设备中拉出： adb pull /system/priv-app/SystemUI/SystemUI.apk路径SystemUI.apk可能不同
framework-res.apk从您的设备中拉出adb pull /system/framework/framework-res.apk的路径framework-res.apk可能不同
跑 apktool if framework-res.apk
跑 apktool if SystemUI.apk
跑 apktool d SystemUI.apk
打开SystemUI\res\layout\status_bar.xml并添加android:visibility="gone"到最顶部的 xml 元素（对我来说是com.android.systemui.statusbar.phone.PhoneStatusBarView）
跑 apktool b SystemUI
转到SystemUI\original并复制AndroidManifest.xml并META-INF到SystemUI\build\apk\
apktool b SystemUI再次运行
进入SystemUI\dist\和覆盖设备的原始SystemUI.apk与一个在SystemUI\dist\SystemUI.apk用adb push SystemUI\dist\SystemUI.apk /system/priv-app/SystemUI/SystemUI.apk
重启设备

A great solution I found for that issue, setting each Activity theme& windowSoftInputModeto the following values :

我为该问题找到了一个很好的解决方案，将每个 Activity theme&windowSoftInputMode设置为以下值：

<activity   android:name=".MyActivity"
            android:theme="@android:style/Theme.NoTitleBar.Fullscreen" 
            android:windowSoftInputMode="adjustResize">  <!-- theme : to set the activity to a full screen mode without a status bar(like in some games) -->
</activity>                                              <!-- windowSoftInputMode : to resize the activity so that it fits the condition of displaying a softkeyboard -->

I don't have a perfect solution but a workaround here. The basic idea is to listen the system ui status changes and force navigation/status bar as invisible. It takes effect as similar as setting IMMERSIVE_STICKY mode but disappearing navigation/status bar quicker than IMMERSIVE_STICKY.

我没有完美的解决方案，但这里有一个解决方法。基本思想是监听系统 ui 状态变化并强制导航/状态栏不可见。它的作用类似于设置 IMMERSIVE_STICKY 模式，但比 IMMERSIVE_STICKY 更快地消失导航/状态栏。

here it is:

这里是：

set system ui style in onCreate() and on onResume function, and set system ui change listener

在 onCreate() 和 onResume 函数中设置系统 ui 样式，并设置系统 ui 更改侦听器

    mDecroView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                                      |    View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                                      | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                                      | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                                      | View.SYSTEM_UI_FLAG_FULLSCREEN
                                      | View.SYSTEM_UI_FLAG_IMMERSIVE);
    mDecroView.setOnSystemUiVisibilityChangeListener(this);

force system bar as invisible in onSystemUiVisibilityChange, setting system ui some seconds later otherwise it would take on effect(does not know exactly why, maybe system just ignores the system ui setting request when system bar showing not yet completed)

强制系统栏在 onSystemUiVisibilityChange 中不可见，设置系统 ui 几秒钟后，否则它会生效（不知道确切原因，也许系统只是在系统栏显示尚未完成时忽略系统 ui 设置请求）

    public void onSystemUiVisibilityChange(int visibility) {
    // TODO Auto-generated method stub
    Log.d(TAG, "onSystemUiVisibilityChange called with visibility " + visibility);
    if((visibility & View.SYSTEM_UI_FLAG_FULLSCREEN) == 0){
        if(null == mHandler){
            mHandler = new MyHandler();
        }
        if(null != mHandler){
            mHandler.removeMessages(MSG_HIDE_SYSTEM_BAR);
            mHandler.sendEmptyMessageDelayed(MSG_HIDE_SYSTEM_BAR, 50);
        }
        //the deccro view is not in full screen
        Log.d(TAG, "setSystemUiVisibility");
        Log.d(TAG, "current system ui is " + mDecroView.getSystemUiVisibility());


    }
}

then you can set system ui like this:

然后你可以像这样设置系统用户界面：

public void handleMessage(Message msg) {
        // TODO Auto-generated method stub
        super.handleMessage(msg);
        switch(msg.what){
        case MSG_HIDE_SYSTEM_BAR:
                           mDecroView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                    | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                    | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                    | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                    | View.SYSTEM_UI_FLAG_FULLSCREEN
                    | View.SYSTEM_UI_FLAG_IMMERSIVE);
            break;
        }
    }

try this code:

试试这个代码：

disable statusbar and navbar

禁用状态栏和导航栏

adb shell
su 
pm disable com.android.systemui
reboot

enable statusbar and navbar

启用状态栏和导航栏

adb shell
su 
pm enable com.android.systemui
reboot

It works on Android 5.1.1 but the usb camera is down

它适用于 Android 5.1.1，但 USB 摄像头已关闭

Another way (my device worked without any problems)

另一种方式（我的设备没有任何问题）

Remove System Navigation Bar ? The Android System Navigation Bar is the bar at the bottom of the screen which presents the back, home, and app-switch soft-keys.

删除系统导航栏？Android 系统导航栏是屏幕底部的栏，显示返回、主页和应用程序切换软键。

As the system navigation bar is independent from any installed Android application in particular, removing it is done in the Android OS.

由于系统导航栏独立于任何已安装的 Android 应用程序，因此删除它是在 Android 操作系统中完成的。

To accomplish this on a rooted installed device you can set the qemu.hw.mainkeys property to 1 by editing /system/build.prop:

要在有根安装的设备上完成此操作，您可以通过编辑 /system/build.prop 将 qemu.hw.mainkeys 属性设置为 1：

qemu.hw.mainkeys=1

To accomplish this at build time you would set the 'config_showNavigationBar' value to false in your device overlay (ie device/gateworks/ventana/overlay/frameworks/base/core/res/res/values/config.xml):

要在构建时完成此操作，您需要在设备叠加层（即 device/gateworks/ventana/overlay/frameworks/base/core/res/res/values/config.xml）中将 'config_showNavigationBar' 值设置为 false：

<bool name="config_showNavigationBar">false</bool>

Note you could also make build.prop modifications at build time by adding to the PRODUCT_DEFAULT_PROPERTY_OVERRIDES or ADDITIONAL_BUILD_PROPERTIES variables which can be found in your device target configuration (ie imx6.mk and BoardConfig.mk in device/gateworks/ventana/).

请注意，您还可以在构建时通过添加到 PRODUCT_DEFAULT_PROPERTY_OVERRIDES 或 ADDITIONAL_BUILD_PROPERTIES 变量来修改 build.prop，这些变量可以在您的设备目标配置中找到（即设备/gateworks/ventana/ 中的 imx6.mk 和 BoardConfig.mk）。

Additionally, you can hide the navigation bar (and status bar) within an application by setting the SYSTEM_UI_FLAG_HIDE_NAVIGATION flag however it will pop back if the user touches anywhere on the screen. http://trac.gateworks.com/wiki/Android/Kiosk

此外，您可以通过设置 SYSTEM_UI_FLAG_HIDE_NAVIGATION 标志来隐藏应用程序中的导航栏（和状态栏），但是如果用户触摸屏幕上的任何位置，它就会弹出。 http://trac.gateworks.com/wiki/Android/Kiosk

add this before : setContentView(R.layout.x);

在此之前添加： setContentView(R.layout.x);

this.requestWindowFeature(Window.FEATURE_NO_TITLE);    // Removes title bar
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,                 
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.x);
