ProgressDialog给出错误，而我正在使用onCreate（）活动组中的活动

我的代码如下。ProgressDialog给出错误，而我正在使用onCreate（）活动组中的活动

public void onCreate(Bundle savedInstanceState) { 
    ................ 
    ................ 
    showDialog(CONTACT_DIALOG_ID); 
      Thread t = new Thread() { 
       public void run(){ 
        try{ 

         sleep(50000); 
        } catch(Exception e) { 
         Log.e("TAG","Exception caught in thread:" + e.toString()); 
         //e.printStackTrace(); 
        } finally { 
         try{ 
          dismissDialog(CONTACT_DIALOG_ID); 
         } catch (IllegalArgumentException e) { 
          Log.w("TAG","Dialog does not exist"); 
         } 
        } 
        //finish(); 
       } 
      }; 
      t.start(); 
    ................ 
    ................ 
}

和对话是..

@Override 
    protected Dialog onCreateDialog(int id) { 
     Dialog dialog = null; 
     switch (id) { 
     case CONTACT_DIALOG_ID: 
      dialog = new ProgressDialog(this); 
      ((ProgressDialog) dialog).setMessage("Loading, please wait..."); 
      break; 
     } 
     return dialog; 
    }

对话框不显示，我得到错误如下

多线程在Android中http://www.scribd.com/doc/46948116/Android-Chapter13-Multi更换dismissDialog(CONTACT_DIALOG_ID); - 线程书签。 – 2011-03-09 12:16:47

你的问题是你试图从非ui线程修改ui。使用handlers这样的事情。这是一个很好的example。

请给我一个排序的例子。 – 2011-03-09 11:00:01

更新了答案。 – 2011-03-09 11:10:44

我不理解如何实现它。我试过但没有成功。 – 2011-03-09 11:49:11

或者你也可以尝试像下面

与下面的代码

runOnUiThread(new Runnable() 
    {    
     @Override 
     public void run() 
     { 
      dismissDialog(CONTACT_DIALOG_ID); 
     } 
    });
