安卓app 怎么连接mysql

android 链接mysql数据库实例：

package com.hl

import java.sql.DriverManager

import java.sql.ResultSet

import com.mysql.jdbc.Connection

import com.mysql.jdbc.Statement

import android.app.Activity

import android.os.Bundle

import android.view.View

import android.view.View.OnClickListener

import android.widget.Button

import android.widget.TextView

public class AndroidMsql extends Activity {

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState)

setContentView(R.layout.main)

Button btn=(Button)findViewById(R.id.btn)

btn.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

sqlCon()

}

})

}

private void mSetText(String str){

TextView txt=(TextView)findViewById(R.id.txt)

txt.setText(str)

}

private void sqlCon(){

try {

Class.forName("com.mysql.jdbc.Driver")

} catch (Exception e) {

e.printStackTrace()

}

try {

String url ="jdbc:mysql://192.168.142.128:3306/mysql?user=zzfeihua&password=12345&useUnicode=true&characterEncoding=UTF-8"//链接数据库语句

Connection conn= (Connection) DriverManager.getConnection(url)//链接数据库

Statement stmt=(Statement) conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE)

String sql="select * from user"//查询user表语句

ResultSet rs=stmt.executeQuery(sql)//执行查询

StringBuilder str=new StringBuilder()

while(rs.next()){

str.append(rs.getString(1)+"\n")

}

mSetText(str.toString())

rs.close()

stmt.close()

conn.close()

} catch (Exception e) {

e.printStackTrace()

}

}

}

不过eclipse老是提示：

warning: Ignoring InnerClasses attribute for an anonymous inner class that doesn't come with an associated EnclosingMethod attribute. (This class was probably produced by a broken compiler.)

手机是不能直接去连接你服务器的mysql数据库

请在你的服务端写代码去连接mysql数据吧

Mysql连接方法

1. 加载数据库驱动: Class.forName("org.gjt.mm.mysql.Driver") //加载数据库驱动

String url = "jdbc:mysql://localhost:3306/test"

String user = "root"

String passowrd = "123456"

2. 获取数据库连接Connection con数= DriverManager.getConnection(url,user,password)

3. 获取SQL执行器 PreparedStatement prepare = con.prepareStatement("SQL语句")

4. 执行SQL语句,得到结果集 ResultSet result = prepare.executeQuery()

while(result.next()){

  //读取结果

}

最后不要忘记导入jdbc驱动包

纯工手打字,请采纳哈
