title: listview doesn't scroll after filtering
body: <p>I have a listview. And I have also a custom adapter that extends BaseAdapter. In my custom adapter I implemented interface Filterable. After filtering I call notifyDataSetChanged() method of adapter, then it works fine ( It updates the list items ). But, after this I can't scroll my listview.
  Why this happens?</p>
  
  <p><strong>ANSWER:</strong> This happens because my listview was inside the GridLayout, when I changed GridLayout to LinearLayout and set some proper parameters it worked perfectly. </p>
