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

btn_register.setOnClickListener(new View.OnClickListener() {                              @Override               public void onClick(View v) {                   // TODO Auto-generated method stub                    if(doBeforeSubmit()){                                  try {                           Log.v(TAG, "clientThread prepare01。。。:"+Thread.interrupted());                           clienThread=new Thread(){                               public void run() {                                   try {                                       Log.v(TAG, "clientThread prepare02。。。:"+Thread.interrupted());                                       while (!Thread.interrupted()) {                                           Log.v(TAG, "clientThread starting。。。");                                           MeApiCall meApiCall=new MeApiCallImpl();                                           Me me=new Me();                                           me.setMeEmail(et_register_account.getText().toString().trim());                                           me.setMePwd(et_register_pwd.getText().toString().trim());                                           me.setMeName(et_register_nickName.getText().toString().trim());                                                                                                                           Log.v(TAG, "clientThread data loaded。。。");                                                                                 meApiCall.register(me);                                           Log.v(TAG, "clientThread callback。。。");                                                                                  handler.sendEmptyMessage(AppConfig.Register.SUCCESS_MSG);                                                                                                                            clienThread.interrupt();   //中断线程                                        }                                   } catch (InterruptedException e) {                                       // TODO: handle exception                                        Log.v(TAG, "clientThread is interrupt");                                   }catch (Exception e) {                                       // TODO Auto-generated catch block                                        Log.v(TAG, "exception: "+e.getMessage());                                       handler.sendEmptyMessage(AppConfig.Register.FAIL_OTHER_MSG);                                       e.printStackTrace();                                   }                               };                              };                           Log.v(TAG, "progressDialog prepare01。。。:");                           progressDialog=ProgressDialog.show(Register.this,                                                               "",                                                               "正在获取....",                                                               true,                                                               true,                                                              new DialogInterface.OnCancelListener() {                                                                                                                              @Override                                                               public void onCancel(DialogInterface dialog) {                                                                   // TODO Auto-generated method stub                                                                                                                                           try {                                                                           clienThread.interrupt();                                                                           Log.v(TAG, "interrupt is success!");                                                                       } catch (Exception e) {                                                                           // TODO Auto-generated catch block                                                                            Log.v(TAG, "interrupt is fail!");                                                                           e.printStackTrace();                                                                       }                                                                                                                              }                                                           }                                                             );                           Log.v(TAG, "clientThread prepareing_end。。。");                           clienThread.start();                           //Log.v(TAG, "clientThread prepareing_end。。。");
