一、关于超时链接的解决思路

	// 登录超时处理线程class LoginOutTimeProcess implements Runnable {public boolean running = false;private long startTime = 0L;private Thread thread = null;LoginOutTimeProcess() {}public void run() {while (true) {if (!this.running)return;if (System.currentTimeMillis() - this.startTime > 20 * 1000L) {mHandler.sendEmptyMessage(LOGIN_OUT_TIME);}try {Thread.sleep(10L);} catch (Exception localException) {}}}public void start() {try {this.thread = new Thread(this);this.running = true;this.startTime = System.currentTimeMillis();this.thread.start();} finally {}}public void stop() {try {this.running = false;this.thread = null;this.startTime = 0L;} finally {} 
 /** 

 
* 初始化好友数组 

 
*/ 

 
private void initUserData() { 

 
// TODO Auto-generated method stub 

 
// 实例化组名 

 
mGroup = new ArrayList(); 

 
mChildren = new HashMap>();// 给每一组实例化child 

 
List dbUsers = mUserDB.getUser();// 查询本地数据库所有好友 

 
// 初始化组名和child 

 
for (int i = 0; i < groups.length; ++i) { 

 
mGroup.add(groups[i]);// 组名 

 
List childUsers = new ArrayList();// 每一组的child 

 
mChildren.put(i, childUsers); 

 
} 

 
// 给每一组添加数据 

 
for (User u : dbUsers) { 

 
for (int i = 0; i < mGroup.size(); ++i) { 

 
if (u.getGroup() == i) { 

 
mChildren.get(i).add(u); 

 
} 

 
} 

 
} 

 
mAdapter = new MyExpandableListAdapter(mGroup, mChildren); 

 
xListView.setAdapter(mAdapter); 

 
}
