Android 【山西违章查询实现2】（解析网页源码然后ListView显示出来）--- 客户端获取html源码

废话不多说，直接上源码

 最后网页源码在result中。

public void btn(View view)
    {
        new myWorker().execute("这里是网址");
    }　　　　//异步操作，防止UI线程阻塞。
    private class myWorker extends AsyncTask<String,Void,String>
    {
        protected String doInBackground(String...urls)
        {
            StringBuilder builder = new StringBuilder(100000);
            for (String url : urls) {　　　　　　　　
                DefaultHttpClient client = new DefaultHttpClient();　　　　　　　　　　
                HttpGet httpGet = new HttpGet(url);
                try {
                    HttpResponse execute = client.execute(httpGet);
                    InputStream content = execute.getEntity().getContent();
                    BufferedReader buffer = new BufferedReader(new InputStreamReader(content));
                    String s = "";
                    while ((s = buffer.readLine()) != null) {
                        builder.append(s);
                    }
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
            return builder.toString();
        }
        protected void onPostExecute(String result)
        {　　　　　　　　　　　　　　//源码显示在Textview中
            TextView textView=(TextView)findViewById(R.id.tv1);

            textView.setText(result);
            //获得源码
        }
    }

获取结果
