SMS メッセージを送受信するアプリを開発しています。基本的な考え方は、ユーザーがメッセージを送信した連絡先のリストを処理する 1 つのアクティビティと、特定の連絡先との会話を表示する 1 つのアクティビティを用意することです。したがって、最初のアクティビティは連絡先のリストであり、ユーザーがいずれかを選択すると、別のアクティビティが開始され、選択したユーザーとの会話スレッドが表示されます。
会話が長すぎない場合、私が行ったことは機能します。この場合、会話スレッドは正常に表示されます。一方、会話に多くのメッセージが含まれている場合、アプリはしばらくロードされてから連絡先リストに戻り、選択した連絡先の電話番号を連絡先リストに追加するか、単にリストに戻ります連絡先。
なぜこれが起こっているのかわかりません。助けていただければ幸いです。コードは次のとおりです。
