之前学习了通过Openfire+spark+smack的模式来完成我们的即时通讯软件,上次我们已经完成了Openfire的安装和配置,这次我们继续完成我们的客户端部分。
1.首先我们通过百度smack来下载我们所需要的jar包,将下载好的jar包导入到我们的工程中,创建一个工具类XmppTool:
package com.xmpp.client.util; import org.jivesoftware.smack.ConnectionConfiguration; import org.jivesoftware.smack.XMPPConnection; import org.jivesoftware.smack.XMPPException; import org.json.JSONArray; public class XmppTool { private static XMPPConnection con = null; private static void openConnection(String url, String pcName) { try { // url、端口,也可以设置连接的服务器名字,地址,端口,用户。 ConnectionConfiguration connConfig = new ConnectionConfiguration( "192.168.2.113", 5222, "JEREHEDU"); con = new XMPPConnection(connConfig); con.connect(); } catch (XMPPException xe) { xe.printStackTrace(); } } private static void openOffConnection(String url, String pcName) { try { ConnectionConfiguration connConfig = new ConnectionConfiguration( url, 5222, pcName); connConfig.setSendPresence(false); con = new XMPPConnection(connConfig); con.connect(); } catch (XMPPException xe) { xe.printStackTrace(); } } public static XMPPConnection getOffConnection(String url, String pcName) { if (con == null) { openOffConnection(url, pcName); } return con; } public static XMPPConnection getConnection(String url, String pcName) { if (con == null) { openConnection(url, pcName); } return con; } public static void closeConnection() { con.disconnect(); con = null; } }
主要还是通过ConnectionConfiguration来连接服务器,传入三个参数(地址,端口,用户名)
2.登陆界面
package com.xmpp.client; import java.util.Iterator; import org.jivesoftware.smack.XMPPException; import org.jivesoftware.smack.packet.Presence; import org.jivesoftware.smackx.OfflineMessageManager; import com.xmpp.client.util.XmppTool; import com.xmpp.client.R; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.os.Handler; import android.util.Log; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.EditText; import android.widget.LinearLayout; import android.widget.Toast; public class FormLogin extends Activity implements OnClickListener { private EditText useridText, pwdText, urlText, pcnameText;; private LinearLayout layout1, layout2; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.formlogin); // 获取用户和密码 this.useridText = (EditText) findViewById(R.id.formlogin_userid); this.pwdText = (EditText) findViewById(R.id.formlogin_pwd); this.urlText = (EditText) findViewById(R.id.formlogin_url); this.pcnameText = (EditText) findViewById(R.id.formlogin_pcname); // 正在登录 this.layout1 = (LinearLayout) findViewById(R.id.formlogin_layout1); // 登录界面 this.layout2 = (LinearLayout) findViewById(R.id.formlogin_layout2); Button btsave = (Button) findViewById(R.id.formlogin_btsubmit); btsave.setOnClickListener(this); Button btcancel = (Button) findViewById(R.id.formlogin_btcancel); btcancel.setOnClickListener(this); } @Override public void onClick(View v) { // 根据ID来进行提交或者取消 switch (v.getId()) { case R.id.formlogin_btsubmit: // 取得填入的用户和密码 // 取得填入的用户和密码 final String USERID = this.useridText.getText().toString(); final String PWD = this.pwdText.getText().toString(); final String URL = this.urlText.getText().toString(); final String PCNAME = this.pcnameText.getText().toString(); Thread t = new Thread(new Runnable() { public void run() { // sendEmptyMessage:发送一条消息 handler.sendEmptyMessage(1); try { // 连接 XmppTool.getOffConnection(URL, PCNAME).login(USERID, PWD); getOfflineMessage(); // 状态 Presence presence = new Presence( Presence.Type.available); XmppTool.getConnection(URL, PCNAME) .sendPacket(presence); Intent intent = new Intent(); intent.setClass(FormLogin.this, FormClient.class); intent.putExtra("USERID", USERID); intent.putExtra("URL", URL); intent.putExtra("PCNAME", PCNAME); FormLogin.this.startActivity(intent); FormLogin.this.finish(); } catch (XMPPException e) { XmppTool.closeConnection(); handler.sendEmptyMessage(2); } } }); t.start(); break; case R.id.formlogin_btcancel: finish(); break; } } /** * 获取离线消息 */ private void getOfflineMessage() { OfflineMessageManager offlineManager = new OfflineMessageManager( XmppTool.getConnection(this.urlText.getText().toString(), this.pcnameText.getText().toString())); Iterator<org.jivesoftware.smack.packet.Message> it; try { it = offlineManager.getMessages(); while (it.hasNext()) { org.jivesoftware.smack.packet.Message message = it.next(); Log.i("离线消息", "收到离线消息, Received from 【" + message.getFrom() + "】 message: " + message.getBody()); } // 删除离线消息 offlineManager.deleteMessages(); } catch (XMPPException e) { // TODO Auto-generated catch block e.printStackTrace(); } } private Handler handler = new Handler() { public void handleMessage(android.os.Message msg) { if (msg.what == 1) { layout1.setVisibility(View.VISIBLE); layout2.setVisibility(View.GONE); } else if (msg.what == 2) { layout1.setVisibility(View.GONE); layout2.setVisibility(View.VISIBLE); Toast.makeText(FormLogin.this, "登录失败!", Toast.LENGTH_SHORT) .show(); } }; }; }
3.聊天客户端

其中有好多类都是自带的我们只需要实现它就可以了。
