单击 Firebase 通知时打开除 MainActivity 以外的其他 activity

Question

在我的应用程序中，我想打开自定义 activity（不是 MainActivity）和 putExtra 这个 activity 当点击 Firebase 通知。
我写了下面的代码，但是当点击通知打开 MainActivity，但我想打开我的 另一个 activity ( AuctionDetailActivity).

我的 NotificationManager class :

public class MyNotificationManager {

    private Context mCtx;
    private Uri soundUri;
    private static MyNotificationManager mInstance;

    public MyNotificationManager(Context context) {
        mCtx = context;
    }

    public static synchronized MyNotificationManager getInstance(Context context) {
        if (mInstance == null) {
            mInstance = new MyNotificationManager(context);
        }
        return mInstance;
    }

    public void displayNotification(String title, String body) {

        soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

        Intent intent = new Intent(mCtx, MainActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);
        intent.putExtra("fcm_notification", "Y");

        PendingIntent pendingIntent = PendingIntent.getActivity(mCtx, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(mCtx, Constants.NOTIF_CHANNEL_ID)
                .setSmallIcon(R.mipmap.ic_launcher)
                .setContentTitle(title)
                .setSound(soundUri)
                .setAutoCancel(true)
                .setVibrate(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400})
                .setContentText(body)
                .setContentIntent(pendingIntent);

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

        if (mNotifyMgr != null) {
            mNotifyMgr.notify(1, mBuilder.build());
        }
    }
}

和 MyFirebaseMessagingService class :

public class MyFirebaseMessagingService extends FirebaseMessagingService {

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        showNotify(remoteMessage.getFrom(), remoteMessage.getNotification().getBody());
    }

    private void showNotify(String title, String body) {
        MyNotificationManager myNotificationManager = new MyNotificationManager(getApplicationContext());
        //myNotificationManager.displayNotification(title, body);
        myNotificationManager.displayNotification(title, body);
    }
}

MainActivity 代码：

@Override
protected void onResume() {
    super.onResume();
    String fcm_notification = getIntent().getStringExtra("fcm_notification");
    Log.d("FireBaseIntentLog", " FCM : " + fcm_notification);
    if (getIntent().getExtras() != null) {
        for (String key : getIntent().getExtras().keySet()) {
            String value = getIntent().getExtras().getString(key);
            Log.d("FireBaseIntentLog", "Key: " + key + " Value: " + value + " FCM : " + fcm_notification);
        }
    }
}

我该如何解决？

Answer 1

更改下面这行

Intent intent = new Intent(click_action);

至此

Intent intent = new Intent(getActivity(), YourClass.class);

Answer 2

如果您使用 FCM API 从 Firebase 控制台或 notification 字段内发送通知，应用程序有两种行为 -

如果您的应用在前台，将调用 FCM 服务 class 的方法 onMessageReceived。
如果您的应用程序在后台运行，则您的 FCM 服务内不会发生任何事情 class。相反，通知将由 FCM 库本身在内部处理，并且将显示意图中带有启动器 activity 的通知。

并且如果您使用 FCM API 发送通知并使用 data 字段，则无论您的应用程序是否在前景或背景。

所以为了解决您的问题，您可以使用以下两种解决方案之一：

使用 FCM API 发送通知并使用 data 字段而不是 notification 字段。检查 documentation 阅读更多关于 FCM API.
在你的启动器（主）中 activity，检查里面的意图 onCreate 如果它来自通知，阅读额外内容，完成主 activity 然后打开你需要的 activity.

第二种情况示例：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    if (checkIntent()) return;

    // other code.
}

@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    checkIntent();
}

private boolean checkIntent() {
    // to receive the value, send the value as custom data from Firebase console.
    String value = getIntent().getStringExtra("your_key");

    if (value == null) return false;

    if (value.equals("something")) {
        // open one activity.

    } else if (value.equals("another_thing")) {
        // open another activity.
    }

    finish();
    return true;
}

你只需要在sendNotification函数中修改

public void sendNotification(String messageBody, String messageTitle, int user_id, String click_action) {
    Intent intent = new Intent(mCtx, AuctionDetailActivity.class); // Need modify this line
    intent.putExtra(Extras.bidID.name(), user_id);

    PendingIntent pendingIntent = PendingIntent.getActivity(mCtx, 0, intent,
            PendingIntent.FLAG_ONE_SHOT);

    Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(mCtx, Constants.NOTIF_CHANNEL_ID);
    notificationBuilder.setSmallIcon(R.mipmap.ic_launcher)
            .setContentTitle(messageTitle)
            .setContentText(messageBody)
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);

    NotificationManager notificationManager = (NotificationManager) mCtx.getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(0, notificationBuilder.build());
}

Answer 4

如下所示更改您的 MyFirebaseMessagingService class 将 OtherApp.class 替换为您的 activity 名称

public class MyFirebaseMessagingService extends FirebaseMessagingService {

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
    Intent intent=new Intent(this,OtherApp.class);
    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(this,0,intent,PendingIntent.FLAG_ONE_SHOT);//newbg PendingIntent.getActivity(this,0,intent,PendingIntent.FLAG_ONE_SHOT);
    NotificationCompat.Builder notificationBuilder= new NotificationCompat.Builder(this);
    notificationBuilder.setContentTitle("FCM NOTIFICATION"); notificationBuilder.setContentText(remoteMessage.getNotification().getBody());
    notificationBuilder.setAutoCancel(true);
    notificationBuilder.setSmallIcon(R.mipmap.ic_launcher);
    notificationBuilder.setContentIntent(pendingIntent);
    NotificationManager notificationManager =(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(0,notificationBuilder.build());

   }
}

单击 Firebase 通知时打开除 MainActivity 以外的其他 activity

Open a different activity other than MainActivity when clicking Firebase Notification
