私はプロジェクトでMVPパターンを使用し、Viewインターフェイスで進行ダイアログを表示する方法を定義し、プレゼンターで使用しました。次のエラーメッセージがコンパイル時に出力される。Android getActivity、getContext、フラグメント内のgetViewは定義されていません

IフラグメントでgetActivity()方法及びgetContext()メソッドを呼び出すことを試み、そして現在のコードは、に転記Google MVPサンプルコードは、フラグメントgetView()メソッドを使用する方法を提供しますが、エラーはまだコンパイルされます。私はプロジェクトでGreenDAOを使用して、エラーが発生したときにgreendaoタスクの実装では、Gradle情報のコンパイルを参照してくださいが、私はこの問題を解決する方法を知らない、あなたが私を助けることを願って、ありがとう
ありがとうございましたが、私はこの問題を解決してきた、私は別のモジュールでGreenDaoデータ実体を置きます、そしてコンパイルすることができます。 – XvJianzhe
