android利用Http协议获取网页文本内容的方法如下：
public String getWebText(String url){ String s=""; HttpGet hg=new HttpGet(url); HttpClient hc=new DefaultHttpClient(); try { HttpResponse hr = hc.execute(hg); if(hr.getStatusLine().getStatusCode()==HttpStatus.SC_OK){ s=EntityUtils.toString(hr.getEntity()); } } catch (ClientProtocolException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } return s;}
