Question

我正在使用parse.com android进行自定义推送通知。 Push已成功集成到我的应用程序中，但问题是我一次收到两个通知。

一个来自我的自定义Receiver带有图像和其他一个默认通知来自操作系统而没有任何图像，并且该通知甚至没有从通知栏中删除，如果我将其删除，它会一次又一次地出现在通知托盘上。我也会在下面粘贴我的代码段和图片。

// My Custom Receiver Class

public class CustomPushReceiver extends ParsePushBroadcastReceiver {
    private final String TAG = CustomPushReceiver.class.getSimpleName();

    private NotificationUtils notificationUtils;

    private Intent parseIntent;

    public CustomPushReceiver() {
        super();
    }

    @Override
     public void onReceive(Context context, Intent intent) {
        super.onPushReceive(context, intent);

        if (intent == null)
            return;
            parseIntent = intent;
        try {
            String action = intent.getAction();
            JSONObject json = new JSONObject(intent.getExtras().getString("com.parse.Data"));
            if (action.equalsIgnoreCase("com.parse.push.intent.RECEIVE")) {
//                NOTIFICATION_ID++;
                String title = "DW";
                if (json.has("alert"))
                {
                    String text = json.getString("alert");
                    generateNotification(context, title, json, text,parseIntent);
                }
            }
        } catch (JSONException e) {
        }
 }

    @Override
    protected void onPushDismiss(Context context, Intent intent) {
        super.onPushDismiss(context, intent);
    }

    @Override
    protected void onPushOpen(Context context, Intent intent) {
        super.onPushOpen(context, intent);
    }

   private void generateNotification(Context context, String title, JSONObject json, String text, Intent intent) {
//        Intent intent = new Intent(context, home.class);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
        PendingIntent contentIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_ONE_SHOT);

        NotificationManager mNotifM = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

        android.support.v4.app.NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(context)
                        .setSmallIcon(R.drawable.log_pic_small)
                        .setLargeIcon(BitmapFactory.decodeResource(context.getResources(), R.drawable.log_pic))
                        .setAutoCancel(true)
                        .setContentTitle(title)
                        .setContentText(text)
                        .setStyle(new NotificationCompat.BigTextStyle().bigText(text))
                        .setTicker(text)
                        .setLights(Color.GREEN, 500, 500);
        mNotifM.cancel(0);
        mBuilder.setContentIntent(contentIntent);
        mNotifM.notify(110, mBuilder.build());
    }
}

Answer 1

每次都不要生成通知，而是在应用程序启动时首次初始化

CustomPushReceiver customReciever = new CustomPushReceiver（getApplicationContext（））;

//将此RECIEVER设置为您的推送工厂

getPushManager（）。setNotificationFactory（customReciever）;

Answer 2

我认为您的问题是由super.onPushReceive(context, intent);中的方法public void onReceive(Context context, Intent intent)生成的。

我认为你应该覆盖protected void onPushReceive(Context context,Intent intent)并在那里处理推送通知。注意：如果覆盖onPushReceive，请不要调用超级，因为它会再次显示推送。

根据Parse文档：

收到推送通知时调用。默认情况下，广播如果数据中存在“动作”，则会发送意图如果“警报”和“标题”存在，将显示通知数据

修改

public class CustomPushReceiver扩展ParsePushBroadcastReceiver { .....从你的exaple开始编码......

@Override public void onReceive(Context context, Intent intent) { super.onReceive(Context context, Intent intent); } @Override public void onPushReceive(Context context, Intent intent) { //NO SUPER CALL ....exact code from your onReceive..... } ... rest of the code from your example...

}

我认为你可以从这里处理它。

使用Parse.com和Android进行两次自定义推送通知
