Android Things:Raspberry Pi 屏幕超时 [英] Android Things: Raspberry Pi screen timeout

问题描述

我正在使用 Android Things 在 Raspberry Pi 上构建应用程序，并且我有 7 英寸触摸屏，但屏幕永远不会关闭.

I'm building app on Raspberry Pi with Android Things and I have 7 inch touch screen, but the screen never turns off.

是否可以像在 Android 手机中那样设置超时?或强制关闭/打开.

Is it possible to set timeout like in Android phones? or force it to turn off/on.

如果我拔掉电源线重新插入屏幕，它会在我重新启动之前无法工作.

If I remove the power line and inserted again the screen, it will not work until I reboot.

推荐答案

有两个系统设置可以控制此过程:STAY_ON_WHILE_PLUGGED_IN 和 SCREEN_OFF_TIMEOUT

There are two system settings that control this process: STAY_ON_WHILE_PLUGGED_IN and SCREEN_OFF_TIMEOUT

STAY_ON_WHILE_PLUGGED_IN 设置默认设置为 BATTERY_PLUGGED_AC.您可以使用 Settings API 以编程方式在应用程序代码中更改此值:

The STAY_ON_WHILE_PLUGGED_IN setting is set to BATTERY_PLUGGED_AC by default. You can programmatically change this value in your application code with the Settings API:

Settings.Global.putInt(getContentResolver(),
        Settings.Global.STAY_ON_WHILE_PLUGGED_IN, 0);

如果更方便，您也可以从命令行进行此更改:

You can also make this change from the command line if it is more convenient:

$ adb shell settings put global stay_on_while_plugged_in 0
