一般解析xml后获得图片地址，需要显示到ImageView中，
public Bitmap getBitmap(){ Bitmap mBitmap = null; try { URL url = new URL(imageUrl); HttpURLConnection conn = (HttpURLConnection) url.openConnection(); InputStream is = conn.getInputStream(); mBitmap = BitmapFactory.decodeStream(is); } catch (MalformedURLException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } return mBitmap; }
