安装Xampp是否无需再另外安装apache + mysql + php

安装Xampp是否无需再另外安装apache + mysql + php,第1张

不需用,是集成的环境包,其中的a就是apachem就是mysqlp就是PHP

不叫翻译软件的。。。

推荐用editplus编辑器,等你成熟了,直接记事本就可以了,好多人可以的哦

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.)
