Dynamically adding elements to ArrayAdapter

Question

I will try to explain my problem with adding elements to my ArrayAdapter and refresh the ListView:

I have two tabs [TAB1][TAB2], with two Fragments and attached with TabListeners.

I request a WebService to retrieve my first elements (15 items more or less) of the ListView, with getLoaderManager().initLoader(0x01, null, this);
If I scroll at the bottom of the ListView, I request to populate more items (20 items more or less), with AsyncTask.
AsyncTask add more items to an ArrayAdapter, then I mArrayAdapter.notifyDataSetChanged();
Click on the [TAB2] and then return to [TAB1]
The initLoader is called again, BUT the ArrayAdapter still have the elements of the first call!

I'm missing something? I need to store the ArrayAdapter, onSaveInstance or similar? Thank you in advance.

when you create ArrayAdapter you send a ListArray to it.when you want change content .you only change this listArray then where you do't want Listview show your already items you should empty this listArray.

Thank you for the idea, I solved the question, as you say, changing this ListArray.
