1、Java代码
1、user
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) {

}
public String getTime() {
return time;
}
public void setSpace(String space) {

}
public String getSpace() {
return space;
}
public void setWen(String wen) {

this.name=name;
this.riqi=riqi;
this.time=time;

}
2、dao
package dao;
import android.os.Build;
import androidx.annotation.RequiresApi;
import java.sql.*;
import bean.User;
import util.DBUtil;
public class Dao {
public void add(User user) {
//获得链接对象
Connection connection = DBUtil.getConn("users");
//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.setString(1, user.getName());
preparedStatement.setString(2, user.getRiqi());
preparedStatement.setString(3, user.getTime());

preparedStatement.setString(5, user.getWen());
preparedStatement.executeUpdate();
preparedStatement.close();
connection.close();
}
}
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
3、DBUtil
package util;
import java.sql.Connection;
import java.sql.DriverManager;
public class DBUtil{
private static String driver = "com.mysql.jdbc.Driver";// MySql驱动
private static String user = "用户名";
private static String password = "密码";

String ip = "本机IP";
// 尝试建立到给定数据库URL的连接

}catch (Exception e){
