Question

我希望Notification打开Notification.class活动而不是MainActivity。我已将代码更改为：

Intent intent = new Intent(this, Notification.class);

但是当收到通知并点击它时，它仍会打开MainActivity。我看了很多例子，但无法获得我需要改变的地方而不是MainActivity。

通知作为用户段从firebase控制台发送。

        Log.d(TAG, "From: " + remoteMessage.getFrom());

        // Check if message contains a data payload.

Answer 1

可能就是这样，改变了对此的意图：

 Intent intent = new Intent(this, Notification.class);

因此，澄清来自 firebase控制台的您无法仅通过API打开除MainActivity之外的其他活动。

<强>为什么：

由于两件事。

<强>一个：

从控制台发送的通知不会触发onMessageReceived（）。

<强>两个：

firebase cosole通知无法设置点击操作。

修复方法：

从API发送通知并设置click_actions。

示例：

<?php



#API access key from Google API's Console



    define( 'API_ACCESS_KEY', 'YOUR_API_KEY');



    $topic = "/topics/todos";



$url = 'https://fcm.googleapis.com/fcm/send';

$fields = array (

        'to' => $topic,

        'notification' => array (

                "body" => "nova casa adicionada",

                "title" => "Nova casa",

                "sound"=> "default",

                "click_action"=> "Notification"

        ),

        'data' => array(

            "localcasa" => "Porto",

            "precocasa"=> "1.600.000 €",

            "imgurl"=> "http://brunoferreira.esy.es/imgsandroid/casa10.jpg",

            "infocs"=> "Apartamento localizado em local premium da cidade do Porto, à Avenida Marechal Gomes da Costa, onde pode viver-se com toda a calma e descontração. No ponto mais elevado da Foz, com vista de mar e uma envolvente de luxo, rodeado por moradias, com exteriores amplos e vistas deslumbrantes. É constituída por 4 quartos, 5 casas de banho e uma garagem em que tem a capacidade para 2 carros.",

            "csid"=> "10"

        )

);

$fields = json_encode ( $fields );

$headers = array (

        'Authorization: key=' . API_ACCESS_KEY,

        'Content-Type: application/json'

);



$ch = curl_init ();

curl_setopt ( $ch, CURLOPT_URL, $url );

curl_setopt ( $ch, CURLOPT_POST, true );

curl_setopt ( $ch, CURLOPT_HTTPHEADER, $headers );

curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, true );

curl_setopt ( $ch, CURLOPT_POSTFIELDS, $fields );



$result = curl_exec ( $ch );

curl_close ( $ch );



?>

要设置 click_ action ，请在 android清单中设置通知语言：

<intent-filter>
                <action android:name="Notification" />

                <category android:name="android.intent.category.DEFAULT" />

            </intent-filter>

Answer 2

json从服务器发送到应用程序

{

   "notification": {
   "title": "Title",
   "text": "notification",
   "icon": "ic_launcher",
   "click_action": "NOTIFICATION_ACTIVITY"
   }
}

将其放入Android Menifest：

<activity
          android:name=".acitivy.MainActivity"
          android:screenOrientation="portrait"
          android:theme="@style/AppTheme" >

        <intent-filter>
           <action android:name="NOTIFICATION_ACTIVITY" />

           <category android:name="android.intent.category.DEFAULT"/>
        </intent-filter>

</activity>

在sendNotification方法的MyFirebaseMessagingService.class中添加以下内容：

private void sendNotification(RemoteMessage remoteMessage, String messageBody) {
    Intent intent = new Intent(this, MainActivity.class);

    **//Add this line**
    Map<String, String> extra = remoteMessage.getData();
    for (Map.Entry<String, String> entry : extra.entrySet()) {
        intent.putExtra(entry.getKey(), entry.getValue());
    }

    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);

    Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
            .setDefaults(Notification.DEFAULT_ALL)
            .setSmallIcon(Build.VERSION.SDK_INT > 20 ?  R.drawable.notification_icon_white : R.mipmap.ic_launcher_normal)
            //.setLargeIcon(Build.VERSION.SDK_INT > 20 ?  BitmapFactory.decodeResource(getResources(), R.drawable.notification_icon_white) : BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher_normal))
            .setContentTitle(getString(R.string.app_name))
            .setDefaults(NotificationCompat.DEFAULT_SOUND | NotificationCompat.DEFAULT_VIBRATE | NotificationCompat.DEFAULT_LIGHTS)
            .setColor(ContextCompat.getColor(this, R.color.colorPrimary))
            .setPriority(Notification.PRIORITY_HIGH)
            .setContentText(messageBody)
            .setAutoCancel(true)
            .setStyle(new NotificationCompat.BigTextStyle().bigText(messageBody))
            .setDefaults(Notification.DEFAULT_LIGHTS | Notification.DEFAULT_SOUND)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);

    NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    notificationBuilder.build().flags |= Notification.FLAG_AUTO_CANCEL;
    notificationManager.notify(getID(), notificationBuilder.build());
}

Answer 3

修改sendNotifcation方法中的代码。如您所见，您已撰写MainAcitivity.class而不是NotificationActivity.class。我猜这是一个错字

  /** 
     * Create and show a simple notification containing the received FCM message. 
     * 
     * @param messageBody FCM message body received. 
     */ 
    private void sendNotification(String messageBody) {
        Intent intent = new Intent(this, NotificationActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
                PendingIntent.FLAG_ONE_SHOT);

        Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.notification_bg)
                .setContentTitle("FCM Message") 
                .setVibrate(new long[] { 1000, 1000, 1000, 1000, 1000 }) 
                .setLights(Color.RED, 3000, 3000)
                .setContentText(messageBody)
                .setAutoCancel(true) 
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);

        NotificationManager notificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
    }

我在您提供的代码中未找到sendNotification()的来电。我确信您看到的通知来自 Firebase ，而不是来自sendNotification()。见this page。如果您的应用程序在后台并且通知有效负载包含通知部分，那么您的通知将被发送到系统托盘，在单击启动时，Launcher活动会以通知的形式将任何数据从通知传递到Launcher活动。

要解决您的问题，请仅发送数据消息并在sendNotification()的适当位置致电onMessageReceived()，意图Notification.class。
