如何將數據以double類型插入到phpmyadmin中？

Question

我使用eclipse來創建一個android應用程序，它將讀取用戶輸入的價格。

價格應輸入storeed到數據庫（phpMyAdmin的）

我使用下面的代碼，但這次月食有錯誤，並要求我的雙重轉換爲字符串。

  food = Double.parseDouble(inputFood.getText().toString()); 
      transport = Double.parseDouble(inputTransport.getText().toString()); 
      tele = Double.parseDouble(inputTele.getText().toString()); 
      academic = Double.parseDouble(inputAcademic.getText().toString()); 
      entertainment = Double.parseDouble(inputEntertainment.getText().toString()); 
      health = Double.parseDouble(inputHealth.getText().toString()); 
      others = Double.parseDouble(inputOthers.getText().toString()); 
      budget = Double.parseDouble(inputBudget.getText().toString()); 

      total = food + transport + tele + academic + entertainment + health + others;   
      balance = budget - total; 

      List<NameValuePair> params = new ArrayList<NameValuePair>(); 
      params.add(new BasicNameValuePair("food", food)); 
      params.add(new BasicNameValuePair("transport", transport)); 
      params.add(new BasicNameValuePair("tele", tele)); 
      params.add(new BasicNameValuePair("academic", academic)); 
      params.add(new BasicNameValuePair("entertainment", entertainment)); 
      params.add(new BasicNameValuePair("health", health)); 
      params.add(new BasicNameValuePair("others", others)); 
      params.add(new BasicNameValuePair("budget", budget)); 
      params.add(new BasicNameValuePair("total", total)); 
      params.add(new BasicNameValuePair("balance", balance)); 

      JSONObject json = jsonParser.makeHttpRequest(url_save_expenses, 
           "GET", params); 

是否有任何其他編碼用於存儲雙數據？

謝謝回答..

只寫你的代碼，在列表中添加PARAMS這樣

 params.add(new BasicNameValuePair("food", "" + food)); 
     params.add(new BasicNameValuePair("transport", "" + transport)); 
     params.add(new BasicNameValuePair("tele", "" + tele)); 
     params.add(new BasicNameValuePair("academic", "" + academic)); 
     params.add(new BasicNameValuePair("entertainment", "" + entertainment)); 
     params.add(new BasicNameValuePair("health", "" + health)); 
     params.add(new BasicNameValuePair("others", "" + others)); 
     params.add(new BasicNameValuePair("budget", "" + budget)); 
     params.add(new BasicNameValuePair("total", "" + total)); 
     params.add(new BasicNameValuePair("balance", "" + balance)); 

這將你的雙類型更改爲String此Constuctor，並在服務器端上的將字符串轉換爲加倍並存入數據庫
