我使用eclipse来创建一个android应用程序,它将读取用户输入的价格。如何将数据以double类型插入到phpmyadmin中?
价格应输入storeed到数据库(phpMyAdmin的)
我使用下面的代码,但这次月食有错误,并要求我的双重转换为字符串。
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);
是否有任何其他编码用于存储双数据?
谢谢回答..
感谢您的回复。我的程序现在没有错误,但数据仍然无法存储到数据库中。最后是“不幸的是,系统已经停止” – user1850936
