Android中断线程的处理

我先描述下我的问题：

我现在对一个用户注册的功能

1.用ProgressDialog将当前页面设成不可操作（保留返回键 退出ProgressDialog）

2.用一个线程clientThread执行数据的提交和返回

问题：考虑到ProgressDialog运行过程中，返回键的操作，应该终止clientThread的运行。

以下是我的代码，希望大家互相讨论，指出我的不足，最好能给出比较好的解决方案

好了不废话了，先贴代码！！

我还是把我btn_register的操作都贴上来好了

1. btn_register.setOnClickListener(new View.OnClickListener() {  
2.               
3.             @Override  
4.             public void onClick(View v) {  
5.                 // TODO Auto-generated method stub   
6.                 if(doBeforeSubmit()){  
7.           
8.                     try {  
9.                         Log.v(TAG, "clientThread prepare01。。。:"+Thread.interrupted());  
10.                         clienThread=new Thread(){  
11.                             public void run() {  
12.                                 try {  
13.                                     Log.v(TAG, "clientThread prepare02。。。:"+Thread.interrupted());  
14.                                     while (!Thread.interrupted()) {
