java - 除了标题和代码 fragment 之外，如何在标记中包含 ID

Question

当在 map android studio中添加标记时，我只能输入标题和 fragment 。如何添加id等其他参数？我稍后可以在单击标记时获得。

private void addMarker(LatLng latlng, final String title, final String deskripsi, final String id) {
   markerOptions.position(latlng);
   markerOptions.title(title);
   markerOptions.snippet(deskripsi);

   gMap.addMarker(markerOptions);

   gMap.setOnInfoWindowClickListener(new GoogleMap.OnInfoWindowClickListener() {
   @Override
       public void onInfoWindowClick(Marker marker) {
           Toast.makeText(getApplicationContext(), marker.getTitle(), Toast.LENGTH_SHORT).show();
       }
   });
}

Answer 1

使用一个 Hashmap 来存储标记和 ID

   private HashMap<Marker, Integer> markerIdMapping = new HashMap<>();


 private void addMarker(LatLng latlng, final String title, final String deskripsi, final String id) {
        markerOptions.position(latlng);
        markerOptions.title(title);
        markerOptions.snippet(deskripsi);

        Marker marker = gMap.addMarker(markerOptions);
        markerIdMapping.put(marker, id);

        gMap.setOnInfoWindowClickListener(new GoogleMap.OnInfoWindowClickListener() {
            @Override
            public void onInfoWindowClick(Marker marker) {
                Toast.makeText(getApplicationContext(), marker.getTitle(), Toast.LENGTH_SHORT).show();
                String markerId = markerIdMapping.get(marker);
            }
        });
    }
