prevent data being loaded everytime in DialogFragment

I have created a custom AlergDialog using DialogFragment with the help of Android Compatibility Support Package

In my custom dialog i have a listview inside a dialog and the content of the listview are being loaded from Sqlite Database in Android. This dialog gets popped up from a listview which is inside a fragment only.

Now t, whenever i click on listview (which is inside a fragment) a dialog appears whit the data into listview successfully , but each time i press on listitem ( which is inside a fragment) every time , the data gets load from the database in a dialog box's listview bcoz onCreate is being called every time so wht i want is data should be loaded at once for all listitem of listview which is inside of fragment.

Code

Whenever a listitem in a fragment gets clicked , i make a call to custom DialogFragment

DalogFragment newFragment = TemplateToContact.newInstance("hi");
newFragment.show(getFragmentManager(), "dialog");

OnCreate of DialogFragment

@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        contactDB = new ContactDB(getActivity().getApplicationContext());
    contactDataList = contactDB.getAllContacts();
        templateContactAdapter = new TemplateContactAdapter();

    }

in OnCreateDialog i create a custom alertdialog box , set the adapger and return it 

@Override
 public Dialog onCreateDialog(Bundle savedInstanceState) {

   LayoutInflater factory = LayoutInflater.from(getActivity());         
   View v = factory.inflate(R.layout.cdialog, null);
   builder = new AlertDialog.Builder(getActivity());

   builder.setView(v);

   templateContactDlg = builder.create();                

   templateContactList = (ListView)v.findViewById(R.id.contactDlgList);            

   templateContactList.setAdapter(templateContactAdapter);

   return templateContactDlg;

  }

You say you use DialogFragment but your code says AlertDialog. Here is an example of how to use DialogFragment. The Google Android team recommends you use DialogFragment, not AlertDialog.

added:


    @Override
    public void onViewCreated(View view, Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);

        if (savedInstanceState != null) {
            aboutFile = savedInstanceState.getString(FILE_NAME);
        }
    }



    @Override
    public void onSaveInstanceState(Bundle outState) {
        outState.putString(FILE_NAME, aboutFile);
    }

For injecting helper classes, read this, for example.
