前一篇给出了HttpGet的实例，这一篇给出HttpPost的实例。

public class HttpPostDemo extends Activity {    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        BufferedReader in = null;        try {            HttpClient client = new DefaultHttpClient();            HttpPost request = new HttpPost("http://mysomewebsite.com/services/doSomething.do");            List
    
      postParameters = new ArrayList
     
      ();            postParameters.add(new BasicNameValuePair("username", "test"));            postParameters.add(new BasicNameValuePair("password", "test1234"));            UrlEncodedFormEntity formEntity = new UrlEncodedFormEntity(                    postParameters);            request.setEntity(formEntity);            HttpResponse response = client.execute(request);            in = new BufferedReader(            		new InputStreamReader(            				response.getEntity().getContent()));            StringBuffer sb = new StringBuffer("");            String line = "";            String NL = System.getProperty("line.separator");            while ((line = in.readLine()) != null) {                sb.append(line + NL);            }            in.close();            String result = sb.toString();            System.out.println(result);        } catch(Exception e) {        	// Do something about exceptions        } finally {            if (in != null) {                try {                    in.close();                } catch (IOException e) {                    e.printStackTrace();                }            }        }    }}
