机器人临睡前（待机） [英] Android going to sleep (standby)

问题描述

我希望我的Andr​​oid设备进入睡眠状态（屏幕关闭），有一个人的想法怎么办呢？

• 在过去，我用的是电源管理函数 goToSleep（时间），但显然这个功能不存在了，我不明白为什么。




• 其他主题谈论这些行：

   电源管理PM =（电源管理）getSystemService（Context.POWER_SERVICE）;
      激活锁定= pm.newWakeLock（PowerManager.PARTIAL_WAKE_LOCK，我wakelook）;
      wakeLock.acquire（）;
   

但只允许该设备进入睡眠模式，瞒着他到睡眠模式了。

• 我已经尝试过其中包括减少屏幕的亮度的解决方案，但它不是因为设备没有真正进入睡眠模式，真正解决问题。而且我不希望使用下面的code：

    android.provider.Settings.System.putInt（getContentResolver（），Settings.System.SCREEN_OFF_TIMEOUT，timeoutInactivity）;
   

  因为我不想触摸屏幕显示设置，它是一个多解决方案，一个解决方法。

PS：这是一个系统的应用程序，所以我没有任何权利/许可限制

解决方案

 私人PowerManager的mPowerManager;
私人PowerManager.WakeLock mWakeLock;公共无效睡眠（）{
      mWakeLock = mPowerManager.newWakeLock（PowerManager.PROXIMITY_SCREEN_OFF_WAKE_LOCK，标签）;
      mWakeLock.acquire（）;
}
 

试试这个

I want my android device to go to sleep (screen off), has someone an idea how to do it?

• In the past I was using the PowerManager function goToSleep(time), but apparently this function does not exist anymore, I don't understand why.

• Other topics talk about those lines:

  PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
      wakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "My wakelook");
      wakeLock.acquire();
  

But it only allows the device to enter sleep mode, without telling him to go to sleep mode now.

• I already tried the solution which consists of diminishing the luminosity of the screen, but it is not a real solution since the device doesn't really enter sleep mode. And I don't want to use the following code:

  android.provider.Settings.System.putInt(getContentResolver(), Settings.System.SCREEN_OFF_TIMEOUT, timeoutInactivity);
  

  because I don't want to touch the screen display settings and it is more a workaround than a solution.

PS : It's for a system app, so I don't have any right/permission limitation.

解决方案

private PowerManager mPowerManager;
private PowerManager.WakeLock mWakeLock;

public void sleep(){
      mWakeLock = mPowerManager.newWakeLock(PowerManager.PROXIMITY_SCREEN_OFF_WAKE_LOCK, "tag");
      mWakeLock.acquire();
}

Try this
