我可以在我的Android应用程序中禁用systemui吗? [英] Can I disable systemui From within my android app?

问题描述

我使用以下答案为我的应用实现了Kiosk模式: https://stackoverflow.com/a/26013850

I used this answer to achieve a Kiosk Mode for my app: https://stackoverflow.com/a/26013850

我将平板电脑的Kingo Root植根，然后执行以下命令:

I rooted the tablet with Kingo Root and then performed the following commands:

adb shell >
 su >
 pm disable com.android.systemui >

我正在构建一个仅可在我们的设备上用作信息亭的应用程序.

I am building an app that will only be used on our devices as kiosks....

它的效果很好，但我想从Android应用程序本身执行系统ui的禁用和启用.

It works great BUT.. I would like to perform the disable and enable of the system ui from the Android application itself.

在应用程序中是否可以使用系统命令?

Are system commands possible from within an application?

推荐答案

/**
 * Uses Root access to enable and disable SystemUI.
 * @param enabled Decide whether to enable or disable.
 */
public void setSystemUIEnabled(boolean enabled){
    try {
        Process p = Runtime.getRuntime().exec("su");
        DataOutputStream os = new DataOutputStream(p.getOutputStream());
        os.writeBytes("pm " + (enabled ? "enable" : "disable") 
                + " com.android.systemui\n");
        os.writeBytes("exit\n");
        os.flush();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

工作正常.用法:

setSystemUIEnabled(true);  // Enable SystemUI
setSystemUIEnabled(false); // Disable SystemUI
