打开特定活动时 E 推送来自 Firebase 的通知

Question

我有安卓应用程序，并尝试接收推送通知。单击保留通知打开主活动时我的问题，我需要在收到来自Firebase的推送通知时直接打开特定活动。这是我的代码

public class MyFirebaseMessagingService extends FirebaseMessagingService {
    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        super.onMessageReceived(remoteMessage);
        Log.d("msg", "onMessageReceived: " + remoteMessage.getData().get("message"));
        NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.mipmap.app_logo_a)
                .setContentTitle(remoteMessage.getData().get("title"))
                .setContentText(remoteMessage.getNotification().getBody());
        NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        manager.notify(0, builder.build());
        try {
            JSONObject json = new JSONObject(remoteMessage.getData().toString());
            handleDataMessage(json);
        } catch (Exception e) {
            Log.e("Mo", "Exception: " + e.getMessage());
        }
        Intent resultIntent = new Intent(getApplicationContext(), Notification_Page.class);
        startActivity(resultIntent);
    }
    private void handleDataMessage(JSONObject json) {
        if (!NotificationUtils.isAppIsInBackground(getApplicationContext())) {
            // app is in foreground, broadcast the push message
            Intent pushNotification = new Intent(Config.PUSH_NOTIFICATION);
            pushNotification.putExtra("message", message);
            LocalBroadcastManager.getInstance(this).sendBroadcast(pushNotification);
            NotificationUtils notificationUtils = new NotificationUtils(getApplicationContext());
            notificationUtils.playNotificationSound();
            Intent resultIntent = new Intent(getApplicationContext(), Notification_Page.class);
            startActivity(resultIntent);
        } else {
            Intent resultIntent = new Intent(getApplicationContext(), Notification_Page.class);
            startActivity(resultIntent);
        }
    }

Answer 1

您可以在通知中设置挂起的意图。因此，首先创建一个挂起的意图：

PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, Destination.class), 0);

然后将以下参数添加到您的NotificationBuilder，您可以在其中定义通知的标题、说明等：

builder.setContentIntent(contentIntent)

更新：

您的代码中已经有了NotificationCompatBuilder。

替换此内容：

NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.mipmap.app_logo_a)
                .setContentTitle(remoteMessage.getData().get("title"))
                .setContentText(remoteMessage.getNotification().getBody());

有了这个：

PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, Destination.class), PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.mipmap.app_logo_a)
                .setContentTitle(remoteMessage.getData().get("title"))
                .setContentText(remoteMessage.getNotification().getBody())
                .setContentIntent(contentIntent);

Answer 2

您应该考虑使用 PendingIntent 以便在单击通知时能够启动特定活动。将其添加到您的代码中

    Intent intent = new Intent(this, YourActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(this, YOUT_REQUEST_CODE, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    builder.setContentIntent(contentIntent);

即使您没有很好地了解

handleDataMessage，您也可以将代码更改为此代码，但这将允许您在单击通知时启动活动

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);
    Log.d("msg", "onMessageReceived: " + remoteMessage.getData().get("message"));
    //two lines addded
    Intent intent = new Intent(this, YourActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
            .setSmallIcon(R.mipmap.app_logo_a)
            .setContentTitle(remoteMessage.getData().get("title"))
            .setContentText(remoteMessage.getNotification().getBody())
            .setContentIntent(contentIntent);//added line
    NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    manager.notify(0, builder.build());
    try {
        JSONObject json = new JSONObject(remoteMessage.getData().toString());
        handleDataMessage(json);
    } catch (Exception e) {
        Log.e("Mo", "Exception: " + e.getMessage());
    }
}
private void handleDataMessage(JSONObject json) {
    if (!NotificationUtils.isAppIsInBackground(getApplicationContext())) {
        // app is in foreground, broadcast the push message
        Intent pushNotification = new Intent(Config.PUSH_NOTIFICATION);
        pushNotification.putExtra("message", message);
        LocalBroadcastManager.getInstance(this).sendBroadcast(pushNotification);
        NotificationUtils notificationUtils = new NotificationUtils(getApplicationContext());
        notificationUtils.playNotificationSound();
    }
}
