http://developer.android.com/reference/org/apache/http/client/methods/HttpPost.html

你需要化妝HTTP POST請求的URL。你也應該使用Asyntask

public void postData() { 
// Create a new HttpClient and Post Header 
HttpClient httpclient = new DefaultHttpClient(); 
HttpPost httppost = new HttpPost("http://www.yoursite.com/script.php"); 

try { 
    // Add your data 
    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2); 
    nameValuePairs.add(new BasicNameValuePair("id", "12345")); 
    nameValuePairs.add(new BasicNameValuePair("stringdata", "AndDev is Cool!")); 
    httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 

    // Execute HTTP Post Request 
    HttpResponse response = httpclient.execute(httppost); 

} catch (ClientProtocolException e) { 
    // TODO Auto-generated catch block 
} catch (IOException e) { 
    // TODO Auto-generated catch block 
} 
}
