顯示片段android對話框

Question

我正在使用http://www.androidhive.info/2013/11/android-sliding-menu-using-navigation-drawer/教程顯示silder菜單並工作得很好。

現在我想知道一個特定的listview項目，我需要顯示是或否按鈕的對話框。所以我是新手。任何人都可以幫我解決這個問題嗎？

這是我的滑菜單的樣子，正如你可以看到，如果我點擊第三個項目，我需要顯示的對話框，如圖

如果你正在跟蹤這個教程，然後改變你的displayView在MainActivity（INT位置）方法是：

private void displayView(int position) { 
    // update the main content by replacing fragments 
    Fragment fragment = null; 
    switch (position) { 
    case 0: 
     fragment = new HomeFragment(); 
     break; 
    case 1: 
     fragment = new FindPeopleFragment(); 
     break; 
    case 2: 
     AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
       MainActivity.this); 

      // set title 
      alertDialogBuilder.setTitle("Alert"); 

      // set dialog message 
      alertDialogBuilder 
       .setMessage("Pelase select your choice") 
       .setCancelable(false) 
       .setPositiveButton("Yes",new DialogInterface.OnClickListener() { 
        public void onClick(DialogInterface dialog,int id) { 

         //do whatever you want to do when user clicks ok 

        } 
        }) 
       .setNegativeButton("No",new DialogInterface.OnClickListener() { 
        public void onClick(DialogInterface dialog,int id) { 
         // if this button is clicked, just close 
         // the dialog box and do nothing 
         dialog.cancel(); 
        } 
       }); 

       // create alert dialog 
       AlertDialog alertDialog = alertDialogBuilder.create(); 

       // show it 
       alertDialog.show(); 
     break; 
    case 3: 
     fragment = new CommunityFragment(); 
     break; 
    case 4: 
     fragment = new PagesFragment(); 
     break; 
    case 5: 
     fragment = new WhatsHotFragment(); 
     break; 

    default: 
     break; 
    } 

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

     // update selected item and title, then close the drawer 
     mDrawerList.setItemChecked(position, true); 
     mDrawerList.setSelection(position); 
     setTitle(navMenuTitles[position]); 
     mDrawerLayout.closeDrawer(mDrawerList); 
    } else { 
     // error in creating fragment 
     Log.e("MainActivity", "Error in creating fragment"); 
    } 
}
