Android：Googleマップの断片。新しいアクティビティにマーカー情報を表示

Question

Googleマップを使用してアプリを開発しています。特定の情報（店舗タイトル、店舗住所、電話番号など）を持つマーカーを作成しました。マーカーをクリックすると、情報ウィンドウが必要な情報で開きますが、情報ウィンドウをクリックすると、新しいアクティビティ（DetailedInformation.java）に各マーカーの情報を表示します。私はインテントを新しい活動に使用しています。以下は私のコードです：あなたの詳細アクティビティののonCreateメソッドで

GoogleMapsFragment.java

Answer 1

map.setOnInfoWindowClickListener(new GoogleMap.OnInfoWindowClickListener() { 
    @Override 
    public void onInfoWindowClick(Marker marker) { 
     Intent intent = new Intent(GoogleMapsFragment.this.getActivity(), DetailedInformation.class); 
     intent.putExtra("title", marker.getTitle()); 
     intent.putExtra("snippet", marker.getSnippet()); 
     startActivity(intent); 
    } 
}); 

：

String title = getIntent().getStringExtra("title"); 
String snippet = getIntent().getStringExtra("snippet");
