android - google map api v2从url android添加图标

Question

我有一个从网络服务中检索纬度和经度的项目，并将它们添加到谷歌地图标记中。我想为来自 url 的标记添加自定义图标。

    mMap.addMarker(new MarkerOptions()
                    .position(new LatLng(dlat,Dlong))
                    .title(m.group(9))
                    .draggable(false)                                           
                    .snippet(m.group(1)+" "+m.group(10)));

如何从链接添加带有自定义图标的 .icon？

Use this method and use returned bitmap to display in map





public Bitmap getBitmapFromURL(String imageUrl) {
    try {
        URL url = new URL(imageUrl);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setDoInput(true);
        connection.connect();
        InputStream input = connection.getInputStream();
        Bitmap myBitmap = BitmapFactory.decodeStream(input);
        return myBitmap;
    } catch (IOException e) {
        e.printStackTrace();
        return null;
    }
}
