Firebase通知和数据

Question

我正在使用Firebase云消息传递API创建应用程序...我能够从服务器向我的客户端应用程序发送通知和数据.但问题是当应用程序打开时,通知不会在数据出现时触发(我的意思是我记录了它)这不是问题.但是当应用程序关闭时,会收到通知,而我点击通知时会打开活动,而我无法看到日志数据.我需要将数据更新为TextView ..

我的MyFirebaseMessagingService:

public void onMessageReceived(RemoteMessage remoteMessage) {
        // TODO: Handle FCM messages here.
        // If the application is in the foreground handle both data and notification messages here.
        // Also if you intend on generating your own notifications as a result of a received FCM
        // message, here is where that should be initiated.
        Log.d(TAG, "From: " + remoteMessage.getFrom());
        Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
        Log.e("FROM", "From: " + remoteMessage.getFrom());
        String data = remoteMessage.getData().get("message");
        Log.e("KOIII", "Notification Message Body: " + remoteMessage.getNotification().getBody());
       // showNotificationS(remoteMessage.getNotification().getBody(),2);
        if(data.equals("true")){
            Log.e("DATA", "SUCCESS");
           // Fragment1.getInstace().updateTheTextView(data, data, data);
        }
    }

我的清单:

<activity
            android:name=".SplashScreen"
            android:label="@string/app_name"
            android:launchMode="singleInstance">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".myHome"
            android:label="@string/app_name">
        </activity>
<service android:name=".MyFirebaseMessagingService">
            <intent-filter>
                <action android:name="com.google.firebase.MESSAGING_EVENT"/>
            </intent-filter>
        </service>
        <service android:name=".FirebaseIDService">
            <intent-filter>
                <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
            </intent-filter>
        </service>

当您发送带有数据有效负载(通知和数据)的通知消息并且应用程序位于后台时,您可以从用户点击通知而启动的意图的附加内容中检索数据.

从点击通知时启动MainActivity 的FCM示例:

if (getIntent().getExtras() != null) {
    for (String key : getIntent().getExtras().keySet()) {
        String value = getIntent().getExtras().getString(key);
        Log.d(TAG, "Key: " + key + " Value: " + value);
    }
}
