推荐答案

请尝试以下code，

ProgressDialog progDailog = ProgressDialog.show( context,"Process ", "Loading Data...",true,true);

new Thread ( new Runnable()
{
     public void run()
     {
      // your data loading code goes here
     }
}).start();

 Handler progressHandler = new Handler() 
 {

     public void handleMessage(Message msg1) 
     {

         progDailog.dismiss();
         }
 }
