私は継続的に動いている人の位置を表示する別のマーカーを入れたいと思う。私は人がGoogleマップ上で動くようにマーカーを更新したい、私はhttps://stackoverflow.com/a/33885379/5324829リンクから試してみましたが、私はあらかじめ定義された位置にマーカーをアニメーションすることができません、誰も私はこれを解決するために私を助けることができますか？事前のおかげで、ここに私のコードは、後であなたがあなたのバックグラウンドサービスにそれを置くことができ、場所の変更リスナーからコードを削除し、ちょうど目的を確認するためにどこかにボタンのようにそれを置く、としてそれを使用することができます。..位置に基づいてアンドロイドのGoogleマップでマーカーを移動する方法は、apiから来る

あなたの問題についてもう少し詳しく説明できますか？それはあなたが何をしたいのかわかりません –
私はタクシーアプリで乗客に移動すると、私の位置マーカー位置に他のマーカーをアニメートしたいです。 –
