ProgressDialog沒有關閉

這是我的代碼，好像一切都很好，但是當應用程序開始時不會關閉ProgressDialog，它可以取消但不會丟失，並且它自應用程序啓動後就會顯示，不是suposed要這樣ProgressDialog沒有關閉

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

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

 
\t \t \t // update selected item and tit|le, then close the drawer 
 
\t \t \t mDrawerList.setItemChecked(thePos, true); 
 
\t \t \t mDrawerList.setSelection(thePos); 
 
\t \t \t setTitle(navMenuTitles[thePos]); 
 
\t \t \t mDrawerLayout.closeDrawer(mDrawerList); 
 
\t \t \t } 
 
\t \t \t catch(Exception E) 
 
\t \t \t { 
 
\t \t \t \t Log.e("MainActivity", "Error in creating fragment"); 
 
\t \t \t } 
 
\t \t } 
 
\t \t else { 
 
\t \t \t // error in creating fragment 
 
\t \t \t Log.e("MainActivity", "Error in creating fragment"); 
 
\t \t } 
 
\t }}); 
 
       }    \t 
 
      
 
     \t 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(); 
 
       } 
 
      } 
 
     }; \t 
 
    }) 
 
\t .start(); } //After call start method thread called run Method

任何人可以看到錯誤？請告訴我

'當應用程序啓動doesn't關閉ProgressDialog，'。 ???當應用程序啓動時，它應該先顯示一個ProgressDialog，然後才能關閉它。您忘記告訴對話何時應該關閉。此外，你也沒有告訴你顯示它的位置/時間。 – greenapps

好了，幾個小時後，我意識到進度對話框我錯了，我將它添加到onItemClick並在類中進行切換，所以有一個答案將ProgressDialog添加到NavigationDrawer

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

 
\t  private void threadMsg(String msg) { 
 

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

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

 
\t   public void handleMessage(Message msg) {
