Android:如何在 Android list 文件中将通知操作动态绑定(bind)到 Activity ？

专门用于 fire-base 集成。 请给点建议谢谢

最佳答案

在通知中接收自定义消息并根据 KeyWork True 或 False 或您的特定单词转到 Activity 公共(public)类 MyFirebaseMessagingService 扩展 FirebaseMessagingService {

private static final String TAG = "FirebaseMessageService";
Bitmap bitmap;

 /**
 * Called when message is received.
 *
 * @param remoteMessage Object representing the message received from Firebase Cloud Messaging.
 */
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    // There are two types of messages data messages and notification messages. Data messages are handled
    // here in onMessageReceived whether the app is in the foreground or background. Data messages are the type
    // traditionally used with GCM. Notification messages are only received here in onMessageReceived when the app
    // is in the foreground. When the app is in the background an automatically generated notification is displayed.
    // When the user taps on the notification they are returned to the app. Messages containing both notification
    // and data payloads are treated as notification messages. The Firebase console always sends notification
    // messages. For more see: https://firebase.google.com/docs/cloud-messaging/concept-options
    //
    Log.d(TAG, "From: " + remoteMessage.getFrom());

    // Check if message contains a data payload.
    if (remoteMessage.getData().size() > 0) {
        Log.d(TAG, "Message data payload: " + remoteMessage.getData());
    }

    // Check if message contains a notification payload.
    if (remoteMessage.getNotification() != null) {
        Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
    }

    //The message which i send will have keys named [message, image, AnotherActivity] and corresponding values.
    //You can change as per the requirement.

    //message will contain the Push Message
    String message = remoteMessage.getData().get("message");
    //imageUri will contain URL of the image to be displayed with Notification
    String imageUri = remoteMessage.getData().get("image");
    //If the key AnotherActivity has  value as True then when the user taps on notification, in the app AnotherActivity will be opened. 
    //If the key AnotherActivity has  value as False then when the user taps on notification, in the app MainActivity will be opened. 
    String TrueOrFlase = remoteMessage.getData().get("AnotherActivity");

    //To get a Bitmap image from the URL received
    bitmap = getBitmapfromUrl(imageUri);

    sendNotification(message, bitmap, TrueOrFlase);

}


/**
 * Create and show a simple notification containing the received FCM message.
 */

private void sendNotification(String messageBody, Bitmap image, String TrueOrFalse) {
    Intent intent = new Intent(this, MainActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    intent.putExtra("AnotherActivity", TrueOrFalse);
    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)
            .setLargeIcon(image)/*Notification icon image*/
            .setSmallIcon(R.drawable.firebase_icon)
            .setContentTitle(messageBody)
            .setStyle(new NotificationCompat.BigPictureStyle()
                    .bigPicture(image))/*Notification with Image*/
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);

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

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

这是另一个 Activity

    // If a notification message is tapped, any data accompanying the notification
    // message is available in the intent extras. In this project the launcher
    // intent is fired when the notification is tapped, so any accompanying data would
    // be handled here. If you want a different intent fired, set the click_action
    // field of the notification message to the desired intent. The launcher intent
    // is used when no click_action is specified.
    //
    // Handle possible data accompanying notification message.
    if (getIntent().getExtras() != null) {

        for (String key : getIntent().getExtras().keySet()) {
            String value = getIntent().getExtras().getString(key);

            if (key.equals("AnotherActivity") && value.equals("True")) {
                Intent intent = new Intent(this, AnotherActivity.class);
                intent.putExtra("value", value);
                startActivity(intent);
                finish();
            }

        }
    }

这就是数据

{ "data": {
    "image": "https://ibin.co/2t1lLdpfS06F.png",
    "message": "Firebase Push Message Using API"
    "AnotherActivity": "True"
  },
  "to" : "f25gYF3***********************HLI"
}
