android - 为什么谷歌地图 v2 的自定义信息窗口，不加载 url 图片？

Question

我正在使用谷歌地图 v2 开发应用程序，在应用程序中，有自定义信息窗口，它不是从 URL 加载图像(通过图像加载器加载)，请参阅附件图像以获得更多许可。 我的代码在这里-

public class CustomWindowAdapter implements InfoWindowAdapter {
private Activity objactivity;
private List<GroupDealModle> mapList;

public CustomWindowAdapter(Activity objactivity,
        List<GroupDealModle> mapList) {
    this.objactivity = objactivity;
    this.mapList = mapList;
}

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

@Override
public View getInfoWindow(Marker objmarker) {
    View objview  = render(objmarker);
    return objview;
}

private View  render(Marker objmarker) {
    ImageLoader objloader = new ImageLoader(objactivity);
    View view = null;
    if (!objmarker.getTitle().equals("")) {
        int pos = Integer.parseInt(objmarker.getTitle());
        Log.e("==check position==", "" + pos);
        if (mapList != null && mapList.size() > pos) {
            String countvalue = mapList.get(pos).getCount();
            Log.e("==check count==", "" + countvalue);
            if (countvalue.equalsIgnoreCase("1")) {
                LayoutInflater inflater = (LayoutInflater) objactivity
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                view = inflater.inflate(R.layout.balloon_overlay, null, false);
                TextView objbusname = (TextView) view
                        .findViewById(R.id.balloon_item_title);
                TextView objballoon_item_desc = (TextView) view
                        .findViewById(R.id.balloon_item_desc);
                TextView objtitle = (TextView) view
                        .findViewById(R.id.balloon_item_snippet);
                ImageView objimgview = (ImageView) view
                        .findViewById(R.id.userthumb_inbaloon);
                TextView objtextexpired = (TextView) view
                        .findViewById(R.id.textexpired);

                objbusname.setText(mapList.get(pos).getBussiness_name());
                String expirevalue = mapList.get(pos).getExpire_status();
                if (expirevalue != null && expirevalue.equals("1")) {
                    objtextexpired.setVisibility(View.VISIBLE);
                }
                if (expirevalue != null && expirevalue.equals("0")) {
                    objtextexpired.setVisibility(View.GONE);
                }

                objtitle.setText(mapList.get(pos).getDeal_title());
                objballoon_item_desc.setText(mapList.get(pos)
                        .getDescription());
                String imageurl = mapList.get(pos).getImage();
                objloader.DisplayBanner(AppConstants.BASE_URL + imageurl,
                        objimgview, 65, 65);
            } else {
                LayoutInflater inflater = (LayoutInflater) objactivity
                        .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                view = inflater.inflate(R.layout.transparentview, null, false);
                view.setVisibility(View.GONE);
                String userid = mapList.get(pos).getUser_id();
                LatLng objlatlng = objmarker.getPosition();
                double latitude = objlatlng.latitude;
                double longitude = objlatlng.longitude;
                Bundle objbundle = new Bundle();
                Intent objintent = new Intent(objactivity,
                        com.flashdeal.map.MapGroupData.class);
                objbundle.putString("from", "map");
                objbundle.putString("lat", "" + latitude);
                objbundle.putString("longi", "" + longitude);
                objbundle.putString("userid", "" + userid);
                objintent.putExtras(objbundle);
                objactivity.startActivity(objintent);
            }
        }
    }
    return view;

}

此适配器在从服务器下载数据后调用 -

@Override
    protected void onPostExecute(List<GroupDealModle> result) {
        if (objprogress.isShowing()) {
            objprogress.dismiss();
        }
        if (result != null) {
            mapList = result;
            myMap.setInfoWindowAdapter(new CustomWindowAdapter(MainActivity.this,mapList));

            if (result.size() != 0) {
                if (result != null) {
                    addPins(result);
                }
            } else if (frommovecurrent != null
                    && frommovecurrent.equalsIgnoreCase("yes")) {
                frommovecurrent = "no";
                addSingleMarker();
                addPins(result);

                /*
                 * // objLayout . removeAllViews (); // objLayout .addView(
                 * objviewformap ); objMapViewhelper . clearMap( );
                 * AlertDialog .Builder objbuilder = new AlertDialog
                 * .Builder( MainActivity .this); objbuilder . setMessage (
                 * "No deals found" ); objbuilder . setPositiveButton ("ok",
                 * new DialogInterface . OnClickListener () {
                 * 
                 * @Override public void onClick( DialogInterface arg0, int
                 * arg1) { } }); objbuilder . create(); objbuilder .show();
                 */
            } else if (result.size() == 0) {
                addSingleMarker();
                addPins(result);
            }
        }

    }

我看过这个 stackoverflow 讨论

Android Google maps APIv2 InfoWindow and Markers

但无法解决我的问题，请任何人指导我。

Answer 1

map V2 UI 实际上是由另一个进程呈现的。在将 View 传递给 Maps V2 后，您无法修改用于信息窗口的 View。我的猜测是您正在尝试设置 View，然后稍后加载图像，但这是行不通的。先获取图像，然后将其放入 View，然后再将 View 提供给 Maps V2。

这当然包含在您链接到的答案中。
