Answer 1

アダプターの内容をバックグラウンドスレッドから変更しているため、この例外が発生します。UIスレッドからのみアダプターを更新するように実装を変更してください。

例外自体はこれに言及しています：

java.lang.IllegalStateException：アダプターの内容は変更されましたが、ListViewは通知を受信しませんでした。アダプタのコンテンツがバックグラウンドスレッドからではなく、UIスレッドからのみ変更されていることを確認してください。

ListViewとアダプタの適切な使用に関する優れたチュートリアルは次のとおりです 。http ：//www.vogella.com/articles/AndroidListView/article.html
