私のプロジェクトにGoogle MapとPlaceを使用する際の問題に直面しています。私は最高の解決策を見つけるために数日を試しましたが、私はまだありません。AndroidでGoogleマップとPlace APIを組み合わせる方法
私はGoolgeマップとPlace APIを使いたいです。私の目標は、EditTextの検索オートコンプリートにレストランの場所を入力し、Googleマップでこの位置を特定し、周囲に他のレストランをマーカーで表示するときです。
だから、Googleマップを実装してjsonを実装して使用してマーカーを管理することはできますか？
私は、このリンク参照してきた私は、Googleのサービスデータベースは、ユーザーに対して適用されています知っているが、そこにあまりにも多くのマーカーがあると私は新しいと手動
を作成することはできません。

をしかし、それは需要を満たしています私の必要条件
ありがとう！

うんです... あなたは次の操作を行う必要があります... 1）マップフラグメントから呼び出される別のフラグメントを作成します...そこにAPIを実装して、long longをバンドルしてtを返しますマップフラグメント...！ –
私はコードを共有します...私はそれを実装しました...しかし、要件に応じてプロジェクトと統合する必要があります。 –
あなたのアドバイスをいただきありがとうございます、私は多分両方を使用して良いと思う、あなたのコードを参照します –
