2 つの異なる Fragment アクティビティで 2 つの異なる Map Fragment を使用しようとしています。また、SupportMapFragment の設計に従って、マニフェスト ファイルのアプリケーション プロパティの META TAG にマップ キーを保持しています。ただし、マップ ビューはクリアされません。「getMap().clear()」を呼び出しても、2 番目のフラグメントに古いポイントがある同じマップが表示されます。提案してください
別のアクティビティで新しい MapFragment を使用しない限り、これは正常に機能します。新しい MapFragment を使用すると、同じマップ ビューが使用されるため、マップ ビューがクリアされません。
