通过图片的url下载图片并解析为Bitmap：

URL url =new URL(imgurl);

        URLConnection urlconn = url.openConnection();
        urlconn.connect();
        HttpURLConnection httpconn =(HttpURLConnection)urlconn;
        HttpResult = httpconn.getResponseCode();
        System.out.println(HttpResult);
        if(HttpResult != HttpURLConnection.HTTP_OK){

        }
        else {
            int filesize = urlconn.getContentLength();
            Log.d(TAG,"Image size = "+String.valueOf(filesize));
            Bitmap bmp = BitmapFactory.decodeStream(urlconn.getInputStream());

            return bmp;
        }
        }catch (IOException e){
            Log.d(TAG,"failed to read image");
        }
