Question

这是我的问题..

我有一个带有定时器的AlarmManager，它会在定时器到期时触发接收器。

当Timer到期，并且在接收器中触发onReceive时，我想在通知栏中创建 NOTIFICATION 。但是，出于某种原因我遇到了问题..

例如，单词this总是用红色加下划线。
我能够用context替换其中的一些，以摆脱一些错误，
但是有几个地方我仍然有问题..

我肯定做错了一些事情，并且可以真正使用一些帮助！

以下是我的代码，在接收者的onReceive方法中。
非常感谢任何建议！谢谢！

（PS ..点击后，我希望它打开位置/ GPS设置屏幕）..

    // Sets an ID for the notification
    int mNotificationId = 001;


    NotificationManager mNotifyMgr = 
            (NotificationManager) context.getSystemService(NOTIFICATION_SERVICE);


    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(this)
                    .setSmallIcon(R.drawable.ic_notification_messageboxes)
                    .setContentTitle("TITLE OF NOTIFICATION")
                    .setContentText("Description text of the notification");


    Intent resultIntent = 
            new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS);


    PendingIntent resultPendingIntent = 
            PendingIntent.getActivity
                    (context, 0, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);


    mBuilder.setContentIntent(resultPendingIntent);


    mNotifyMgr.notify(mNotificationId, mBuilder.build());

使用此代码

private void sendNotification(String message) {
    Intent intent = new Intent(this, "YOUR CLASS WHERE LAND".class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    int requestCode = 0;
    PendingIntent pendingIntent = PendingIntent.getActivity(this, requestCode, intent, PendingIntent.FLAG_ONE_SHOT);
    Uri sound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationCompat.Builder noBuilder = new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.ic_launcher)
            .setContentTitle("TITLE")
            .setContentText(message)
            .setAutoCancel(true)
            .setContentIntent(pendingIntent)
            .setSound(sound);

    NotificationManager notificationManager = (NotificationManager)
            getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(NOTIFICATION_ID, noBuilder.build());
}

NOTIFICATION_ID每次都是唯一ID。当您在Receiver的onReceive（）方法中收到某些内容时调用此方法。

更新代码：以下是完整代码：

public class GCMPushReceiverService extends GcmListenerService {

Random random = new Random();
int NOTIFICATION_ID = random.nextInt(9999 - 1000) + 1234;

@Override
public void onMessageReceived(String from, Bundle data) {
    String message = data.getString("message");
    Log.e("Notification ", "Received onMessage : " + data);
    sendNotification(message);
}

private void sendNotification(String message) {
    Intent intent = new Intent(this, "YOUR CLASS WHERE LAND".class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    int requestCode = 0;
    PendingIntent pendingIntent = PendingIntent.getActivity(this, requestCode, intent, PendingIntent.FLAG_ONE_SHOT);
    Uri sound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationCompat.Builder noBuilder = new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.ic_launcher)
            .setContentTitle("Title")
            .setContentText(message)
            .setAutoCancel(true)
            .setContentIntent(pendingIntent)
            .setSound(sound);

    NotificationManager notificationManager = (NotificationManager)
            getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(NOTIFICATION_ID, noBuilder.build());
}

}

希望这对你有用。
