Firebaseプッシュ通知-通知に複数行メッセージを表示する方法

Question

プッシュ通知のmessageをの1行だけで取得します。一方、multiple lines with BigPictureStyleおよびBase（両方の通知スタイル）。

添付のScreenshotを参照してください。この画像では、"Hello from Firebase Cloud Messaging"したがって、これは単一行自体に収まります。

しかし、実際には、「Firebase Cloud Messagingからこんにちは、またFirebase Cloud Messagingからこんにちは」を表示しようとすると、それでもsingle line onlyで3つのドットを最後にこのように...

codeに必要なpartは次のとおりです、私は使用しています：

NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setLargeIcon(image)/*Notification icon image*/
                .setSmallIcon(R.mipmap.ic_launcher)
                .setContentTitle(messageTitle)
                .setContentText(messageBody)
                .setStyle(new NotificationCompat.BigPictureStyle()
                        .bigPicture(image)
                        .setBigContentTitle(messageTitle)
                        .setSummaryText(Html.fromHtml(messageBody)
                        .toString()))/*Notification with Image*/
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);

注：同じ問題、私はいつでも直面しています、大きな画像なしでメッセージを送信しています（ベース/シンプルプッシュ通知）

こちらをご覧くださいscreenshot：

したがって、唯一の懸念事項は、Notificationで複数行メッセージを表示する方法？です。

Answer 1

ほとんどありました。 bigText プロパティを設定するだけです。

    NotificationCompat.Builder notificationBuilder =
            new NotificationCompat.Builder(this)
                    .setSmallIcon(R.mipmap.ic_launcher)
                    .setAutoCancel(true);

    NotificationCompat.BigTextStyle bigTextStyle = new NotificationCompat.BigTextStyle();
    bigTextStyle.setBigContentTitle("Title");
    bigTextStyle.bigText("Lorem ipsum dolor sit amet, consectetur adipiscing elit," +
            " sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. " +
            "Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris " +
            "nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in.");

    notificationBuilder.setStyle(bigTextStyle);

    NotificationManager mNotifyMgr = (NotificationManager)
            getSystemService(NOTIFICATION_SERVICE);
    mNotifyMgr.notify(1, notificationBuilder.build());

Answer 2

独自のレイアウトを使用する必要があります。

Builder builder = new Builder(context);
builder.setSmallIcon(R.drawable.star_white)
builder.setAutoCancel(true)
builder.setContentIntent(pendingIntent);
builder.setPriority(NotificationCompat.PRIORITY_MAX);

RemoteViews remoteViewsBig = new RemoteViews(context.getPackageName(), R.layout.notification_big);
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.notification_small);
remoteViewsBig.setImageViewBitmap(R.id.banner, bitmap);

remoteViewsBig.setTextViewText(R.id.button, data.getButtonText());
remoteViews.setTextViewText(R.id.button, data.getButtonText());

remoteViewsBig.setTextViewText(R.id.text_title, data.getTitle());
remoteViews.setTextViewText(R.id.text_title, data.getTitle());

remoteViewsBig.setTextViewText(R.id.text_content, data.getContent());
remoteViews.setTextViewText(R.id.text_content, data.getContent());

builder.setCustomContentView(remoteViews);
builder.setCustomBigContentView(remoteViewsBig);

NotificationManager notificationManager =
            (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(notificationId, builder.build());

そしてxmlファイル：

<?xml version="1.0" encoding="utf-8"?>

Answer 3

これを試して：-

NotificationCompat.Builder builder = new NotificationCompat.Builder(
        context);
Notification notification = builder.setContentIntent(contentIntent)
        .setSmallIcon(icon).setTicker(appname).setWhen(0)
        .setAutoCancel(true).setContentTitle(appname)
        .setStyle(new NotificationCompat.BigTextStyle().bigText(message))
        .setContentText(message).build();

notificationManager.notify(0, notification);

Answer 4

@Dus answer ...を使用して複数行を表示できますが、bigPictureSyleを使用すると、setSummaryTextメソッドに常に単一行があり、他のオプションはRemoteViewを作成し、必要な設計に従ってUIを実装します

RemoteViewを参照- this を参照

Answer 5

これがあなたに使用されることを望みます。これをチェックして：

   NotificationCompat.Builder builder = new NotificationCompat.Builder(
            context);
    Notification notification = builder.setContentIntent(contentIntent)
            .setSmallIcon(icon).setTicker(appname).setWhen(0)
            .setAutoCancel(true).setContentTitle(appname)
            .setStyle(new NotificationCompat.BigTextStyle().bigText(message))
            .setContentText(message).build();

    notificationManager.notify(0, notification);

Answer 6

これは、通知で大きな画像と複数行のテキストを表示する方法です。これは私のプロジェクトで動作するコードです。

Fcmには2種類のfcmメッセージがあります。 Display MessagesおよびData Messages。そして、Data Messagesフォアグラウンドおよびバックグラウンドでfcm通知を処理します。
