ProgressDialog 未关闭

Question

这是我的代码，看起来一切都很好，但是当应用程序启动时不会关闭 ProgressDialog，它是可以取消的，但不会消失，它自应用程序启动后就显示出来，而且它是不应该那样

 private void displayView(int position) {
  final int thePos=position;
  final ProgressDialog myProgressDialog = ProgressDialog.show(MainActivity.this, "", "Procesando...", true);
  myProgressDialog.setCancelable(true);
  new Thread(new Runnable() {
           public void run() {
               try {      
                Thread.sleep(2000);
                 MainActivity.this.runOnUiThread(new Runnable() {
                       @Override
                       public void run() {
                       
       
  // update the main content by replacing fragments
  Fragment fragment = null;
  switch (thePos) {
  /*case 0:
   fragment = new  HomeFragment();
   break;*/
  case 1:
   fragment = new  HomeFragment();
   break;
  case 2:
   fragment = new  CalendarioFragment();
   break;
  case 5:
   fragment = new  ContactoFragment();
   break;
  case 6:
   fragment = new  OnclickFragment();
   break;
  default:
   break;
  }

  if (fragment != null) {
   try{
   FragmentManager fragmentManager = getFragmentManager();
   fragmentManager.beginTransaction().replace(R.id.frame_container, fragment).commit();

   // update selected item and tit|le, then close the drawer
   mDrawerList.setItemChecked(thePos, true);
   mDrawerList.setSelection(thePos);
   setTitle(navMenuTitles[thePos]);
   mDrawerLayout.closeDrawer(mDrawerList);
   }
   catch(Exception E)
   {
    Log.e("MainActivity", "Error in creating fragment");
   }
  } 
  else {
   // error in creating fragment
   Log.e("MainActivity", "Error in creating fragment");
  }
 }});
               }                
           
        catch (Throwable t) {
               // just end the background thread
               Log.i("Animation", "Thread  exception " + t);
           }
       }

       private void threadMsg(String msg) {

           if (!msg.equals(null) && !msg.equals("")) {
               Message msgObj = handler.obtainMessage();
               Bundle b = new Bundle();
               b.putString("message", msg);
               msgObj.setData(b);
               handler.sendMessage(msgObj);
           }
       }

       // Define the Handler that receives messages from the thread and update the progress
       private final Handler handler = new Handler() {

           public void handleMessage(Message msg) {
                
               String aResponse = msg.getData().getString("message");

               if ((null != aResponse)) {
                   myProgressDialog.dismiss();
               }
           }
       }; 
   })
 .start(); } //After call start method thread called run Method

有人能看到错误吗？请给我看看

好吧，几个小时后，我意识到进度对话框是错误的，我将它添加到 onItemClick 中并在 class 中进行切换，所以答案是将 ProgressDialog 添加到导航抽屉

 private class SlideMenuClickListener implements ListView.OnItemClickListener {
  @Override
  public void onItemClick(AdapterView<?> parent, View view, int position,
    long id) {
   final int thePos=position;
   final ProgressDialog myProgressDialog = ProgressDialog.show(MainActivity.this, "", "Procesando...", true);
   myProgressDialog.setCancelable(true);
   new Thread(new Runnable() {
            public void run() {
                try {      
                 Thread.sleep(2000);
                  MainActivity.this.runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
   // display view for selected nav drawer item
   displayView(thePos);
    myProgressDialog.dismiss();
                        }});
                }                
            
         catch (Throwable t) {
                // just end the background thread
                Log.i("Animation", "Thread  exception " + t);
            }
        }

        private void threadMsg(String msg) {

            if (!msg.equals(null) && !msg.equals("")) {
                Message msgObj = handler.obtainMessage();
                Bundle b = new Bundle();
                b.putString("message", msg);
                msgObj.setData(b);
                handler.sendMessage(msgObj);
            }
        }

        // Define the Handler that receives messages from the thread and update the progress
        private final Handler handler = new Handler() {

            public void handleMessage(Message msg) {
                 
                String aResponse = msg.getData().getString("message");

                if ((null != aResponse)) {
                    myProgressDialog.dismiss();
                }
            }
        };
