如何在狀態欄中發送新通知時打開屏幕？

Question

這是我設置通知的代碼，它有效：

@Override
    public void onReceive(Context context, Intent intent) {

        category = (String) intent.getExtras().get("CATEGORY");
        notes = (String) intent.getExtras().get("NOTES");

        PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
                new Intent(context, MainActivity.class), 0);

        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
                context).setSmallIcon(R.drawable.ic_launcher)
                .setContentTitle(category).setContentText(notes);

        mBuilder.setContentIntent(contentIntent);
        mBuilder.setDefaults(Notification.DEFAULT_SOUND);
        mBuilder.setAutoCancel(true);

        NotificationManager mNotificationManager = (NotificationManager) context
                .getSystemService(Context.NOTIFICATION_SERVICE);
        mNotificationManager.notify(1, mBuilder.build());       
    }

這是來自我的 BroadcastReceiver 的代碼片段。 每當調用此 BroadcastReceiver 時，它都會在狀態欄中顯示通知。 在調試過程中，我注意到當屏幕關閉並發出新通知時，屏幕不會打開。 有沒有辦法做到這一點？ 每當發出新通知並且屏幕關閉時，它應該打開一段時間。 模擬就像收到一條新短信。

Answer 1

試試這個：

PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK, "My Tag");
wl.acquire(3000);
wl.release();

Answer 2

createNotification(); //your implementation
PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
boolean isScreenOn = Build.VERSION.SDK_INT >= 20 ? pm.isInteractive() : pm.isScreenOn(); // check if screen is on
if (!isScreenOn) {
    PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP, "myApp:notificationLock");
    wl.acquire(3000); //set your time in milliseconds
}

Answer 3

實際上，如果您只想在收到通知時激活屏幕，請在創建通知后使用此代碼：

PowerManager powerManager = (PowerManager) getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wakeLock = powerManager.newWakeLock(PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP, "Tag");
wakeLock.acquire();
wakeLock.release();
