本文實例講述了Android中斷線程的處理方法。分享給大家供大家參考。具體方法如下：

我現在對一個用戶注冊的功能
1.用ProgressDialog將當前頁面設成不可操作（保留返回鍵退出ProgressDialog）
2.用一個線程clientThread執行數據的提交和返回

問題：考慮到ProgressDialog運行過程中，返回鍵的操作，應該終止clientThread的運行。

代碼如下，感興趣的朋友可以參考運行一下，以便得出更好的解決辦法。

復制代碼代碼如下:

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();   //中斷線程   
                                }  
                            } 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,   
         "",   
         "正在獲取....",   
         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。。。");   
                } catch (Exception e) {  
                    // TODO Auto-generated catch block   
                    Log.v(TAG, e.getMessage()+" 00");  
                    e.printStackTrace();  
                }  
            }  
        }  
    });
