我有纬度和放大器;从database.how长值显示基于纬度和放标志物;使用Android的谷歌地图API v2.In原生Android谷歌地图长期价值，我们展示基于概念itemoverlay标记。在V2中，我不知道如何显示标记。

I have lat&long values from database.how to display markers based on lat &long values using android google map api v2.In original android google maps,we display markers based on concept itemoverlay. In v2,I dont know how to display markers.

    dbAdapter.open();
        Cursor points = dbAdapter.clustercall(Btmlft_latitude, toprgt_latitude,
                Btmlft_longitude, toprgt_longitude, gridsize1);
        int c = points.getCount();
        Log.d("count of points", "" + c);

        if (points != null) {
            if (points.moveToFirst()) {
                do {

                    int latitude = (int) (points.getFloat(points
                            .getColumnIndex("LATITUDE")) * 1E6);
                    int longitude = (int) (points.getFloat(points
                            .getColumnIndex("LONGITUDE")) * 1E6);

                    mapView.addMarker(new MarkerOptions().position(
                            new LatLng(latitude, longitude)).icon(
                            BitmapDescriptorFactory.defaultMarker()));

                } while (points.moveToNext());

            }
        }
        points.close();
        dbAdapter.close();

这是我的codeI我得到的纬度和放大器;从数据库中长值，但如何添加基于纬度和放标志物;长值映射

That is mycode.I am getting lat&long values from database,but how to add markers based on lat &long values to map.

我读了谷歌Android地图API v2.In那些只给出标记的添加静态数据

I read the android google maps api v2.In that have only give statically added data of markers

推荐答案

您必须使用方法 GoogleMap.addMarker（MarkerOptions）; 我在我的博客上的教程说明这一点： http://bon-app-etit.blogspot.be/2012/12/add-informationobject-to-marker-in.html

You have to use the method GoogleMap.addMarker(MarkerOptions); I've explained this in a tutorial on my blog: http://bon-app-etit.blogspot.be/2012/12/add-informationobject-to-marker-in.html
