上传文本到Android Android

我想上传文本数据到Http。我有一个Button和一个EditText的布局。当我点击按钮时，edittext上的文本数据将上传到我的网站。上传文本到Android Android

sendButton.setOnClickListener(new OnClickListener() { 

     public void onClick(View v) { 
      // TODO Auto-generated method stub 

      // get the message from the message text box 
      String msg = msgTextField.getText().toString(); 

      // make sure the fields are not empty 
      if (msg.length() > 0) { 
       HttpClient httpclient = new DefaultHttpClient(); 
       HttpPost httppost = new HttpPost(
         mywebsite...); 

       try { 
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(
          2); 
        nameValuePairs 
          .add(new BasicNameValuePair("id", "12345")); 
        nameValuePairs.add(new BasicNameValuePair("message", 
          msg)); 
        httppost.setEntity(new UrlEncodedFormEntity(
          nameValuePairs)); 
        HttpResponse response = httpclient.execute(httppost); 
        msgTextField.setText(""); // clear text box 
       } catch (ClientProtocolException e) { 
        // TODO Auto-generated catch block 
       } catch (IOException e) { 
        // TODO Auto-generated catch block 
       } 

      } else { 
       // display message if text fields are empty 
       Toast.makeText(getBaseContext(), "All field are required", 
         Toast.LENGTH_SHORT).show(); 
      } 
     } 
    });

在AndroidManifest

<uses-permission android:name="android.permission.INTERNET" />

但是当我运行的应用程序。我有一些问题：

尝试使用AsyncTask并将请求的所有代码放在doInBackground（）方法中。请不要在UiMainTread上加载。
