get the other 50 entries in another temporary arraylist and add them with your original Arraylist by calling the addAll () method of your original arraylist, and then reinstall your listView using the adapter that has your mearged arraylist.

ListView listView = (ListView) findViewById (R.id.myListView);
final ArrayList listItems = new ArrayList ();
final ArrayAdapter adapter = new ArrayAdapter (this, android.R.layout.simple_list_item_1, listItems);
listView.setAdapter (adapter);

Hope this helps you!
