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.

1. I request a WebService to retrieve my first elements (15 items more or less) of the ListView, with getLoaderManager().initLoader(0x01, null, this);
2. If I scroll at the bottom of the ListView, I request to populate more items (20 items more or less), with AsyncTask.
3. AsyncTask add more items to an ArrayAdapter, then I mArrayAdapter.notifyDataSetChanged();
4. Click on the [TAB2] and then return to [TAB1]
5. 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.

Answer 1

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.

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