Question

因此，当用户在屏幕上显示锁定屏幕时收到通知时，应该会亮起。

private void unlockScreen() {
    Window window = this.getWindow();
    window.addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);
    window.addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
    window.addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
}

我有这个解锁屏幕。然后我用它来称呼它

private void updateNotification(int notificationCode)
{
    switch(notificationCode)
    {
        case NotificationService.InterceptedNotificationCode.FACEBOOK_CODE:
            shapeRoundButton.setImageResource(R.drawable.toggle_on);
            unlockScreen();
            break;
        case NotificationService.InterceptedNotificationCode.OTHER_NOTIFICATIONS_CODE:
            shapeRectangleButton.setImageResource(R.drawable.toggle_on);
            break;
    }
}

shapeRoundButton.setImageResource(R.drawable.toggle_on)完全没问题，但是unlockScreen（）;没有按＆＃39;吨。正在收到通知。

任何人都知道为什么屏幕没有解锁或我如何解锁屏幕？干杯！

看到这个

PowerManager pm = (PowerManager)context.getSystemService(Context.POWER_SERVICE);
boolean isScreenOn = pm.isScreenOn();
Log.e("screen on.................................", ""+isScreenOn);
if(isScreenOn==false)
{
    WakeLock wl = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK |PowerManager.ACQUIRE_CAUSES_WAKEUP |PowerManager.ON_AFTER_RELEASE,"MyLock");
    wl.acquire(10000);
    WakeLock wl_cpu = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK,"MyCpuLock");

    wl_cpu.acquire(10000);
}

收到通知后唤醒屏幕
