Android读取本地或网络图片并转换为Bitmap

/**   * 得到本地或者网络上的bitmap url - 网络或者本地图片的绝对路径,比如:   *   * A.网络路径: url="http://blog.foreverlove.us/girl2.png" ;   *   * B.本地路径:url="file://mnt/sdcard/photo/image.png";   *   * C.支持的图片格式 ,png, jpg,bmp,gif等等   *   * @param url   * @return   */  public static Bitmap GetLocalOrNetBitmap(String url)  {   Bitmap bitmap = null;   InputStream in = null;   BufferedOutputStream out = null;   try   {    in = new BufferedInputStream(new URL(url).openStream(), Constant.IO_BUFFER_SIZE);    final ByteArrayOutputStream dataStream = new ByteArrayOutputStream();    out = new BufferedOutputStream(dataStream, Constant.IO_BUFFER_SIZE);    copy(in, out);    out.flush();    byte[] data = dataStream.toByteArray();    bitmap = BitmapFactory.decodeByteArray(data, 0, data.length);    data = null;    return bitmap;   }   catch (IOException e)   {    e.printStackTrace();    return null;   }  }
