进度错误

我想提出一个进度条，而在云进度错误

这里获取数据是我的代码：

public void progressBar() { 
     progress = ProgressDialog.show(this, "dialog title", 
        "dialog message", true); 

       new Thread(new Runnable() { 
        public void run() 
        { 
        // do the thing that takes a long time 
         displayView(); 
        runOnUiThread(new Runnable() { 
         public void run() 
         { 
         progress.dismiss(); 
         } 
        }); 
        } 
       }).start(); 
    }

和我displayView（）;方法

下面是代码：

public void displayView() { 

     listAdapter = new ArrayAdapter<String>(this, R.layout.listview_format, 
       R.id.item_list,handler.getRetrieveData()); 
     listView = (ListView)findViewById(R.id.listView2); 
     listView.setAdapter(listAdapter); 

     listView.setOnItemClickListener(new OnItemClickListener() { 
      public void onItemClick(AdapterView<?> arg0, View v, int position , 
        long id) { 

       intent = new Intent(TechiesActivity.this,ItemInfoActivity.class); 
       startActivity(intent);    
      } 
     }); 

    }

我得到这种类型的错误从logcat的

错误：

只要打电话给runOnUiThread方法里面DisplayView方法，它应该罚款

public void progressBar() { 
     progress = ProgressDialog.show(this, "dialog title", 
        "dialog message", true); 

       new Thread(new Runnable() { 
        public void run() 
        { 
        // do the thing that takes a long time 
         runOnUiThread(new Runnable() { 
         public void run() 
         { 
         displayView();      
         progress.dismiss(); 
         } 
        }); 
        } 
       }).start(); 
    }

真棒兄弟谢谢 – user1708134 2013-02-25 07:11:14

@ user1708134总是乐意帮助兄弟:) – 2013-02-25 07:12:19

不能执行从工人/后台线程任何UI更新。所以你的方法

displayView();

你需要调用它在runOnUiThread()。

runOnUiThread(new Runnable() { 
    public void run() { 
     displayView(); 
     progress.dismiss(); 
    } 
});
