android - 状态栏有新通知发送时如何亮屏？

Question

这是我设置通知的代码，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());       
    }

这是来 self 的 BroadcastReceiver 的代码 fragment 。每当调用此 BroadcastReceiver 时，它都会在状态栏中显示一条通知。在调试过程中，我注意到当屏幕关闭并发出新通知时，屏幕不会打开。有什么办法可以做到这一点吗？每当发出新通知并且屏幕关闭时，它都应该打开一段时间。模拟就像收到一条新短信。

试试这个:

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