根据URL抓取并生成缩略图的Java代码```javapublic static Bitmap loadImageFromUrl(String url, int sc) { URL m; InputStream i = null; BufferedInputStream bis = null; ByteArrayOutputStream out = null; byte isBuffer[] = new byte[1024]; if (url == null) return null; try { m = new URL(url); i = (InputStream) m.getContent();

        bis = new BufferedInputStream(i, 1024 * 4);        out = new ByteArrayOutputStream();        int len = 0;        while ((len = bis.read(isBuffer)) != -1) {            out.write(isBuffer, 0, len);        }        out.close();        bis.close();    } catch (MalformedURLException e1) {        e1.printStackTrace();        return null;    } catch (IOException e) {        e.printStackTrace();    }    if (out == null)        return null;    byte[] data = out.toByteArray();    BitmapFactory.Options options = new BitmapFactory.Options();    options.inJustDecodeBounds = true;    BitmapFactory.decodeByteArray(data, 0, data.length, options);    options.inJustDecodeBounds = false;    int be = (int) (options.outHeight / (float) sc);    if (be <= 0) {        be = 1;    } else if (be > 3) {        be = 3;    }    options.inSampleSize = be;    Bitmap bmp = null;    try {        bmp = BitmapFactory.decodeByteArray(data, 0, data.length, options); // 返回缩略图    } catch (OutOfMemoryError e) {        // TODO: handle exception        System.gc();        bmp = null;    }    return bmp;}
