第三，创建android客户端,代码如下：(我的电脑的ip是：192.168.0.124，测试的时候改成自己的)
package com.example.openfiretest;import android.os.Bundle;import android.app.Activity;import android.view.Menu;import android.view.View;import android.view.View.OnClickListener;import android.view.Window;import android.widget.CheckBox;import android.widget.EditText;import android.widget.Toast;public class MainActivity extends Activity {private EditText accountEditText;private EditText passwordEditText;public void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);requestWindowFeature(Window.FEATURE_NO_TITLE);setContentView(R.layout.activity_main);accountEditText = (EditText) findViewById(R.id.username);passwordEditText = (EditText) findViewById(R.id.password);findViewById(R.id.login).setOnClickListener(new OnClickListener() {public void onClick(View v) {String account = accountEditText.getText().toString();String password = passwordEditText.getText().toString();if (account.equals("") || password.equals("")) {Toast.makeText(MainActivity.this, "账号或密码不能为空！",Toast.LENGTH_SHORT).show();} else {ClientConServer ccs = new ClientConServer(MainActivity.this);boolean b = ccs.login(account, password);// 如果登录成功if (b) {Toast.makeText(MainActivity.this, "登陆成功！",Toast.LENGTH_SHORT).show();// startActivity(new// Intent(LoginActivity.this,MainActivity.class));// MainActivity.account=account;} else {Toast.makeText(MainActivity.this, "登陆失败！",Toast.LENGTH_SHORT).show();}}}});}}package com.example.openfiretest;import org.jivesoftware.smack.ConnectionConfiguration;import org.jivesoftware.smack.XMPPConnection;import org.jivesoftware.smack.XMPPException;import android.content.Context;public class ClientConServer {private static int PORT=5222;private Context context;public ClientConServer(Context context){this.context=context;}public boolean login(String a,String p){ConnectionConfiguration config = new ConnectionConfiguration("192.168.0.124", PORT);/** 是否启用安全验证 */config.setSASLAuthenticationEnabled(false);/** 是否启用调试 */ //config.setDebuggerEnabled(true); /** 创建connection链接 */XMPPConnection connection = new XMPPConnection(config);try {/** 建立连接 */connection.connect();/** 登录*/connection.login(a, p); /** 设置状态 */ Presence presence = new Presence (Presence.Type.available); presence.setStatus("Q我吧"); connection.sendPacket(presence);/** 开启读写线程，并加入到管理类中*///ClientSendThread cst=new ClientSendThread(connection);//cst.start();//ManageClientThread.addClientSendThread(a, cst);return true;} catch (XMPPException e) {e.printStackTrace();}return false; }}<uses-permission android:name="android.permission.INTERNET" />
