Question

enter image description here我正在开发一个地图应用程序，该应用程序通过来自JSON的经度和纬度添加标记。每个纬度和经度也会附带其他信息。我已将此信息存储到数组列表中。标记显示的是确切位置，但是当我尝试在有关标记位置的Google标记单击中将此信息显示到自定义对话框时出现问题，值显示为空。如何解决这个问题呢？

我的MarkerHolder类

public class MarkerHolder {
    public String bunch_jobName;
    public String addess;
    public String destiny;
    public String note;

    public MarkerHolder(String bunch_jobName, String addess, String destiny, String note) {
        bunch_jobName = bunch_jobName;
        addess  = addess;
        destiny = destiny;
        note = note;
    }
}

GoogleMap.setOnMarkerClickListener(new com.google.android.gms.maps.GoogleMap.OnMarkerClickListener() {
    @Override
    public boolean onMarkerClick(Marker marker){
        cal = new Dialog(activity);
        cal.setCanceledOnTouchOutside(true);
        cal.requestWindowFeature(Window.FEATURE_NO_TITLE);
        cal.getWindow().setBackgroundDrawable(new ColorDrawable(0));
        cal.setContentView(R.layout.marker_popup_info);
        cal.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);

        TextView stops_name = cal.findViewById(R.id.tv_stops_name);
        TextView stops_addr = cal.findViewById(R.id.tv_stops_address);
        TextView stops_destination = cal.findViewById(R.id.tv_destiny);
        TextView stops_note = cal.findViewById(R.id.tv_note);
        MarkerHolder mHolder = markerHolderMap.get(marker.getId());


        stops_name.setText(mHolder.bunch_jobName);
        stops_addr.setText(mHolder.bunch_jobName);
        stops_destination.setText(mHolder.bunch_jobName);
        stops_note.setText(mHolder.bunch_jobName);

        cal.show();

        return false;
    }
});

在JSON中使用

MarkerOptions选项=新的MarkerOptions（）; options.position（new LatLng（location_lat1，location_longi1））;

                    Marker marker = GoogleMap.addMarker(options);

                    MarkerHolder mHolder = new MarkerHolder(task_job_name,job_merchant,contact_no,task_address);
                    markerHolderMap.put(marker.getId(), mHolder);

在Android中单击GoogleMap.setOnMarkerClickListener时获取值null
