ログイン後、サーバーからのデータが同期され、データベースに保存されます。データが読み込まれ、カスタムリストビューに表示されます。しかし、それは働いていない、私はそのデータが表示されますバック主な活動に、新しいアクティビティを開く必要があり、ここでMainActivityは次のとおりです。最初の起動時にカスタムリストビューにデータを表示する方法

あなたは新しい活動が実行されることを意味するか、またはあなたがGUIように、新しいアクティビティを開く必要があります"リフレッシュ"？ – chntgomez
このアクティビティが開いているとき、listviewはデータベースからすべてのデータを読み込み、listviewに表示します。 –
私はこの問題を解決しました。それは非同期なのでfirebaseからデータを取得するからです。私のアプリが起動すると、データはまだ完全には取得されていません。 –
