问题描述

我想在一个InfoWindowAdapter显示来自一个URL的图像
 ，我有以下的code，但不显示我的图片

I'm trying to display an image from a url in a "InfoWindowAdapter" ,I have the following code, but does not show me the image

....
mMap = getMap();

mMap.setInfoWindowAdapter(new InfoWindowAdapter() {

  ...

 @Override
 public View getInfoContents(Marker marker) {

  View v = getActivity().getLayoutInflater().inflate(
R.layout.info_window_layout, null);

 String image_url = "http://api.androidhive.info/images/sample.jpg";
 new DownloadImageTask(imgEquipo).execute(image_url);
 return v;
 } 
});

调用的AsyncTask获取的图像

call to AsyncTask to get image

private class DownloadImageTask extends AsyncTask<String, Void, Bitmap> {
    ImageView bmImage;

    public DownloadImageTask(ImageView bmImage) {
        this.bmImage = bmImage;
    }

    protected Bitmap doInBackground(String... urls) {
        String urldisplay = urls[0];
        Bitmap mIcon11 = null;
        try {
            InputStream in = new java.net.URL(urldisplay).openStream();
            mIcon11 = BitmapFactory.decodeStream(in);
        } catch (Exception e) {
            Log.e("Error", e.getMessage());
            e.printStackTrace();
        }
        return mIcon11;
    }

    protected void onPostExecute(Bitmap result) {
        bmImage.setImageBitmap(result);
    } }
 }

推荐答案

这是行不通的，因为你得到的图像之前返回的观点，他们不同步。

It won't work because the view is returned before you get the image, and they are not synchronized.

看看这种方式：

关键是你得到的图像后更新信息窗口。

The trick is to update the InfoWindow after you get the image.
