Question

我被困在这一点上，我必须从网络服务中调用Google Map Marker，我该怎么做my web service。我尝试的是下面的代码不起作用。我想要做的是使用 Picasso 库从Web服务加载图标。
我没有太多关于谷歌地图的知识。如果有人帮助我，那对我来说会很好。

Answer 1

试试这段代码：

导入：

import com.squareup.picasso.Picasso;
import com.squareup.picasso.Target;

` 创建一个类：

 public class PicassoMarker implements Target {
        Marker mMarker;

        PicassoMarker(Marker marker) {
            mMarker = marker;
        }

        @Override
        public int hashCode() {
            return mMarker.hashCode();
        }

        @Override
        public boolean equals(Object o) {
            if (o instanceof PicassoMarker) {
                Marker marker = ((PicassoMarker) o).mMarker;
                return mMarker.equals(marker);
            } else {
                return false;
            }
        }

        @Override
        public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
            mMarker.setIcon(BitmapDescriptorFactory.fromBitmap(bitmap));
        }

        @Override
        public void onBitmapFailed(Drawable errorDrawable) {
        }

        @Override
        public void onPrepareLoad(Drawable placeHolderDrawable) {

        }
    }

现在将addMarkers（）方法修改为：

 private void addMarkers() {
    for (int k = 0; k < venueList.size(); k += 1) {
        try {
            Log.e("pj", venueList.get(k).getMap_icon());

            //new AddMarkerAsyncTask(venueList.get(k),k).execute();

            double ln = Double.parseDouble(venueList.get(k).getLongitude());
            double la = Double.parseDouble(venueList.get(k).getLatitude());
            String title = venueList.get(k).getPost_title() == null ? "" : venueList.get(k).getPost_title();

            Marker marker = googlemap.addMarker(new MarkerOptions()
                    .position(new LatLng(la, ln))
                    .title(title));

            PicassoMarker pmarker = new PicassoMarker(marker);
            Picasso.with(MainActivity.this).setLoggingEnabled(true).fit().load(venueList.get(k).getMap_icon()).into(pmarker);
            hashMap.put(marker, k);

        } catch (Exception e) {
            Log.e("addMarkers", k + "");
            e.printStackTrace();
        }
    }
}

PicassoMarker课程受到Answer

我在您的addMarkers()方法

中添加了一些修改

从Web服务获取Google Map Marker和数据
