私はAppCompatActivityが必要ですが、MapTabActivityは既に拡張されていますSupportMapFragment

Question

AppCompatActivityを拡張しないとエラーが発生します。

どうすれば解決できますか？

私はエラーが

発見された場所は、私は「この」何か他のものとを交換することができ HERE を市場にしましたか？

私は自分のツールバーを作ることができると思っています。

Answer 1

あなたはSupportMapFragmentを使用して、その

getActivity()またはgetContext()てみてくださいされています。

getActivity() - このフラグメントが現在関連付けられているアクティビティを返します。

getContext()

は、それが現在のテーマ、リソースにアクセスするためのビューがで実行されている状況、などを返します

例あなたが活動を混同している

Toast.makeText(getContext(), "permission denied", Toast.LENGTH_LONG).show();
