これは、私は大きな画像や通知で一部のマルチラインテキストを表示するために管理する方法です。これは私のプロジェクトの作業コードです。
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。また、フォアグラウンドとバックグラウンドでfcm通知を処理するのにData Messagesを使用しています。

私は、コードを持っているあなたは@Dus答えを使用して複数のラインを表示することができます...しかしbigPictureSyleと、それは常に単一の行 –
を持っていますテキストと一緒に大きな画像を表示するfirebase通知用。ロジックは、私はアプリケーションにfcm通知で通知ID番号を送信するために使用されます。 'onMessageReceived'アプリケーションは、そのID番号を送信することによって自分のWebアプリケーションと通信し、Webアプリケーションに存在する通知IDに関連するデータをダウンロードし、通知ビルダーに表示します。もしあなたが望むなら、あなたが参照できるようにここにコードを掲載することができます。 –
