Android动态更改标记标题

Question

我的目标是在单击按钮时更改标记标题。问题是我无法在 onCreate() 中获取标记并设置它的标题，因为它是在 onMapReady() 中初始化的。我有以下代码:

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    button.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            updateMarkerTexts(marker, "ss", "gg");
        }
    });

    return view;
}

和

@Override
public void onMapReady(final GoogleMap googleMap) {
    mMap = googleMap;
    enableMyLocation();
    onMyLocationButtonClick();

    final Marker marker = mMap.addMarker(new MarkerOptions()
                .position(new LatLng(51.2001, 62.9187))
                .title("Some title")
                .snippet(getResources().getString(R.string.somestr))));


    mMap.setInfoWindowAdapter(new GoogleMap.InfoWindowAdapter() {
        @Override
        public View getInfoWindow(Marker arg0) {
            LayoutInflater inflater = (LayoutInflater)getContext().getSystemService (Context.LAYOUT_INFLATER_SERVICE);
  //some params
        }

        @Override
        public View getInfoContents(Marker arg0) {
            return null;
        }

        getInfoWindow(marker);
        marker.showInfoWindow();
    }

只需将您的标记实例保存在您的类中，而不是将其保存在您的 onMapReady 范围中:

Marker marker;

@Override
public void onMapReady(final GoogleMap googleMap) {
    ...
    marker = mMap.addMarker(new MarkerOptions()
            .position(new LatLng(51.2001, 62.9187))
            .title("Some title")
            .snippet(getResources().getString(R.string.somestr))));
