こんにちは皆を形成して、私は上のスクリーンショットに示すようにxamarinフォームでカスタム情報ウィンドウを作成する必要がありました。私はそれのためのカスタムレンダラーを作成しましたが、今私が持っている問題は、ボタンがクリックされていないということです。 Xamarinはinfo-window全体をクリック可能なビューとして利用しています。私が間違っていることを教えてください、またはXamarinフォームでボタンのクリックを達成することが可能ですか？前もって感謝します。ここで
は、カスタムレンダラのためのコードです：

ありがとう@ポール、私は自分のために1つを作成し、同じ問題があります。ボタンリスナーはトリガーされません。 –
