私はこのエラーが発生しており、修正方法はわかりません。私は検索し、テーマを設定し、それを変更する、ライブラリを複製するなどの解決策を見つけましたが、何も修正しませんでした！このアクティビティでTheme.AppCompatテーマ（または子孫）を使用する必要があります（stackoverflowによって解決されません）

@XaverKapellerありがとう、あなたはプレビュー（例えばNexus 5のデバイスの横にあるドロップダウン）上記テーマを設定しました。 – Vucko
あなたのアンドロイドサポートデザインライブラリのバージョンは何ですか？ –
また、エラーはありません。その唯一の表示レンダリングの問題です.Javaクラスで初期化すると解決します。無視してください。 –
