这是一个连接到lulpix的AsyncTask，伪造了引荐来源网址和用户代理（lulpix显然通过一些相当la脚的检查来阻止抓取）。开始于您的
Activity：
new ForTheLulz().execute();
结果
Bitmap以相当la脚的方式下载（不进行缓存或检查图像是否已经DL：ed）并且错误处理总体上不存在-但是基本概念应该可以。
class ForTheLulz extends AsyncTask<Void, Void, Bitmap> { @Override protected Bitmap doInBackground(Void... args) { Bitmap result = null; try { document doc = Jsoup.connect("http://lulpix.com") .referrer("http://www.google.com") .userAgent("Mozilla/5.0 (Windows; U; WindowsNT 5.1; en-US; rv1.8.1.6) Gecko/20070725 Firefox/2.0.0.6") .get(); //parse("http://lulpix.com"); if (doc != null) { Elements elems = doc.getElementsByAttributevalue("class", "pic rounded-8"); if (elems != null && !elems.isEmpty()) { Element elem = elems.first(); elems = elem.getElementsByTag("img"); if (elems != null && !elems.isEmpty()) { elem = elems.first(); String src = elem.attr("src"); if (src != null) { URL url = new URL(src); // Just assuming that "src" isn't a relative URL is probably stupid. InputStream is = url.openStream(); try { result = BitmapFactory.depreStream(is); } finally { is.close(); } } } } } } catch (IOException e) { // Error handling goes here } return result; } @Override protected void onPostExecute(Bitmap result) { ImageView lulz = (ImageView) findViewById(R.id.lulpix); if (result != null) { lulz.setImageBitmap(result); } else { //Your fallback drawable resource goes here //lulz.setImageResource(R.drawable.nolulzwherehad); } } }
