【问题描述】：

public void onActivityResult(int requestCode, int resultCode, Intent intent) 

    if (requestCode == SCANNER_REQUEST_CODE) 
        // Handle scan intent
        if (resultCode == Activity.RESULT_OK) 
            // Handle successful scan
            String contents = intent.getStringExtra("SCAN_RESULT");
            String formatName = intent.getStringExtra("SCAN_RESULT_FORMAT");
            byte[] rawBytes = intent.getByteArrayExtra("SCAN_RESULT_BYTES");
            int intentOrientation = intent.getIntExtra("SCAN_RESULT_ORIENTATION", Integer.MIN_VALUE);
            Integer orientation = (intentOrientation == Integer.MIN_VALUE) ? null : intentOrientation;
            String errorCorrectionLevel = intent.getStringExtra("SCAN_RESULT_ERROR_CORRECTION_LEVEL");
            mBarcodeEdit.setText(contents + "\n\n" + formatName);
            tvScanResults.setText(contents + "\n\n" + formatName);

         else if (resultCode == Activity.RESULT_CANCELED) 
            // Handle cancel

        
     else 
        // Handle other intents
    

现在我将扫描的条形码放入edittext 和textview 中，但我想将结果上传到服务器。我将在下面发布 AsyncTask 模块：

        public void send1(View v)
               new Send().execute();

          
            class Send extends AsyncTask<String, Void,Void > 

 HttpClient httpclient;
 HttpPost httppost;
String msg = mBarcodeEdit.getText().toString().trim(); 
           protected Void doInBackground(String... urls) 
        // TODO Auto-generated method stub
         // get the message from the message text box
//   String msg = mBarcodeEdit.getText().toString().trim();
        //Toast.makeText(getBaseContext(),"u clicked           mee",Toast.LENGTH_SHORT).show();
        // make sure the fields are not empty
       if (msg.length()>0)
        

            httpclient = new DefaultHttpClient();
            httppost = new HttpPost("http://yourwebsite.com/yourphpScript.php"); // sever id
         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));
           httpclient.execute(httppost);

          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();
        
    return null;
        

   protected void onProgressUpdate(Void... progress) 

          

        protected void onPostExecute(Void result) 
            mBarcodeEdit.setText(""); // clear text box

@KNeerajLal 不，那部分完全不同，我尝试实现它，但它没有给我所需的解决方案，我只想知道如何从编辑文本中检索数据并将其发送到服务器

您在这样做时遇到了什么问题？

【参考方案1】：

考虑使用 volley 进行客户端-服务器通信。它是谷歌推荐的，最重要的是易于使用，并且可以在后台访问服务器。如果您想知道如何使用 volley，请查看此内容。 http://www.androidhive.info/2014/05/android-working-with-volley-library-1/
