前一篇文章实现了简单的mina服务器端与客户端通信，这篇文章我们要实现android手机上的登录功能。android的应用层语言是java，所以要把前一篇文章的程序改成android版本的也不难。接下来我们来看具体的实现：

服务器端：

和前面一篇文章的一样就可以了，这里不多说了，详细请看android_项目_知识积累_mina通信（java程序简单通信）。然后这里我们要做的就是把前一篇文章的客户端搬到android手机上来。

代码如下：

package com.example.android_mina_client;import java.net.InetSocketAddress;import java.net.SocketAddress;import org.apache.mina.core.filterchain.IoFilter;import org.apache.mina.core.future.ConnectFuture;import org.apache.mina.filter.codec.ProtocolCodecFilter;import org.apache.mina.filter.codec.textline.TextLineCodecFactory;import org.apache.mina.transport.socket.SocketConnector;import org.apache.mina.transport.socket.nio.NioSocketConnector;import android.os.Bundle;import android.app.Activity;import android.view.Menu;import android.view.View;import android.widget.EditText;import android.widget.Toast;public class MainActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);findViewById(R.id.button1).setOnClickListener(new android.view.View.OnClickListener() {@Overridepublic void onClick(View arg0) {// TODO Auto-generated method stubfinal EditText t1 = (EditText) findViewById(R.id.editText1);final EditText t2 = (EditText) findViewById(R.id.editText2);if ("".equals(t1.getText().toString()) || "".equals(t2.getText().toString())) {Toast.makeText(MainActivity.this, "用户名和密码均不能为空！",Toast.LENGTH_LONG).show();} else {// loginnew Thread(){@Overridepublic void run() {// TODO Auto-generated method stubsuper.run();login(t1.getText().toString(),t2.getText().toString());}}.start();}}});}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {// Inflate the menu; this adds items to the action bar if it is present.getMenuInflater().inflate(R.menu.main, menu);return true;}private void login(String username,String userpasswd) {SocketConnector connector = new NioSocketConnector();IoFilter filter = new ProtocolCodecFilter(new TextLineCodecFactory());connector.getFilterChain().addLast("gzm", filter);SocketAddress soketAddress = new InetSocketAddress("192.168.80.105", 5333);//这里我用的局域网，我的电脑的IP是192.168.80.105connector.setHandler(new ClientHandler());ConnectFuture future = connector.connect(soketAddress);future.join();if (!future.isConnected()) {System.out.println("连接服务器失败!");return;}future.getSession().write(username+","+userpasswd);}}

其中的ClientHandler类依然不变，和上一篇文章的一样：

package com.example.android_mina_client;import org.apache.mina.core.service.IoHandlerAdapter;import org.apache.mina.core.session.IoSession;public class ClientHandler extends IoHandlerAdapter {public void messageReceived(IoSession arg0, Object message) throws Exception {System.out.println("服务器发来消息：" + message.toString());}public void exceptionCaught(IoSession arg0, Throwable arg1)throws Exception {}}

整个android工程的结构如下图：

先运行服务器端，然后再运行android客户端，实现的效果如下：
