android - 使用 PowerManager 后，我的设备不再进入睡眠模式

Question

我正在做一个应用程序，我正在三星 Galaxy Y（Android 2.3.6）和 Engel tablet 7"（Android 4.0.x）设备上对其进行测试。

在我的应用程序代码中，我使用此代码段来唤醒设备（当它们处于睡眠模式时）并且运行良好，但现在我的问题是唤醒后它们不再进入睡眠模式，只有它们如果我按下硬件按钮去。任何人都知道如何在使用 PowerManager 后设置默认能量设置？

KeyguardManager km = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE); 
    final KeyguardManager.KeyguardLock kl = km .newKeyguardLock("MyKeyguardLock"); 
    kl.disableKeyguard(); 

    PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE); 
    WakeLock wakeLock = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK
                                     | PowerManager.ACQUIRE_CAUSES_WAKEUP
                                     | PowerManager.ON_AFTER_RELEASE, "MyWakeLock");
    wakeLock.acquire();

Answer 1

尝试这个：

void wakeUpGirls() {
    if (wakeLock != null) {
     wakeLock.release();
    }
   KeyguardManager km = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE);
   KeyguardLock keyguardLock = km.newKeyguardLock("TAG");
   getWindow().addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
  getWindow().addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);

   keyguardLock.disableKeyguard();
   PowerManager pm = (PowerManager)getSystemService(Context.POWER_SERVICE);
   wakeLock = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK 
               | PowerManager.ACQUIRE_CAUSES_WAKEUP 
               | PowerManager.ON_AFTER_RELEASE 
               | PowerManager.SCREEN_BRIGHT_WAKE_LOCK, "MyWakeLock");

   wakeLock.acquire();
}

void sleepGirls() {
    if (wakeLock != null) {
      wakeLock.release();
        wakeLock = null;
   }
}

用这个对我有用

  PowerManager powermanager=  ((PowerManager)getSystemService(Context.POWER_SERVICE));
  WakeLock wakeLock = powermanager.newWakeLock(PowerManager.SCREEN_BRIGHT_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP, "tag");
            wakeLock.acquire(9000);
            wakeLock.release

  KeyguardManager km =(KeyguardManager)getSystemService(KEYGUARD_SERVICE);
            k1 = km.newKeyguardLock("IN");
            k1.disableKeyguard();
