开发体温app

1.编写代码

package bean;

public class User {
   private String name;
   private String riqi;
   private String time;
   private String space;
   private String wen;

   public void setName(String name) {
      this.name = name;
   }

   public String getName() {
      return name;
   }

   public void setRiqi(String riqi) {
      this.riqi = riqi;
   }

   public String getRiqi() {
      return riqi;
   }

   public void setTime(String time) {
      this.time = time;
   }

   public String getTime() {
      return time;
   }

   public void setSpace(String space) {
      this.space = space;
   }

   public String getSpace() {
      return space;
   }

   public void setWen(String wen) {
      this.wen = wen;
   }

   public String getWen() {
      return wen;
   }
   public User(String name,String riqi,String time,String space,String wen){
      this.name=name;
      this.riqi=riqi;
      this.time=time;
      this.space=space;
      this.wen=wen;
   }
}

package dao;

import android.os.Build;

      //获得链接对象

      //准备sql语句
      String sql = "insert into text(name,riqi,time,space,wen)values(?,?,?,?,?)";
      try {
         //创建语句传输对象
         if(connection!=null) {
            PreparedStatement preparedStatement = connection.prepareStatement(sql);
            if (preparedStatement != null) {

               preparedStatement.executeUpdate();
               preparedStatement.close();
               connection.close();
            }
         }
      } catch (SQLException e) {
         // TODO Auto-generated catch block
         e.printStackTrace();
      }
   }
}

            // 尝试建立到给定数据库URL的连接
            connection = DriverManager.getConnection("jdbc:mysql://" + ip + ":3306/" + dbname, user, password);
        }catch (Exception e){
            e.printStackTrace();
        }
        return connection;
