Question

我正在尝试在应用发送通知时打开屏幕。目前，当acquire WakeLock时，它会快速闪烁，几乎不显眼。据我所知，我的旗帜设置正确。 AQUIRE_CAUSES_WAKEUP打开屏幕并ON_AFTER_RELEASE启用（戳用户活动计时器），一旦我将其释放，请将其保持打开状态 - 否则，我明白它会自动关闭..任何人都有洞察力？

PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.ON_AFTER_RELEASE, "TAG");
if(mTurnScreenOn) {
        wl.acquire();
        Log.d("TAG", "WakeLock Acquired");
        if(pm.isScreenOn()) { Log.d("TAG", "Screen is on");
        } else { Log.d("TAG", "Screen is off"); }
}

mNotificationManager.notify(1, notification);

if(mTurnScreenOn) { //release the wakelock if needed
        wl.release();
        Log.d("TAG", "WakeLock Released");
        if(pm.isScreenOn()) { Log.d("TAG", "Screen is on");
        } else { Log.d("TAG", "Screen is off"); }
}

您要设置mTurnScreenOn的值，请查看您在mTurnScreenOn==true时获取唤醒锁定的代码，并且在相同条件下您也将释放它。
