Android - setSelected in OnItemClick in ListView

Question

I am trying to set item selected in OnItemClick event in ListView and it just wouldn't leave item selected. What am I doing wrong?

lView.setOnItemClickListener(new OnItemClickListener()
   {
    @Override
    public void onItemClick(@SuppressWarnings("rawtypes") AdapterView parent, View clickedview, int position, long id)
    {
     clickedview.setSelected(true); 
        mItemsAdapter.select(position);
    }
   }); 

few things:
1. I am trying to implement Multiple Select on the list View.
2. I cannot extend from ListActivity because Activity extends from BaseActivity custom class already.
3. mItemsAdapter is a custom ItemsAdapter adapter that extends BaseAdapter.
4. I don't need a checkbox in there, just to be able to see the row selected is fine.
5. ItemsAdapter overrides getView() and sets the layout of the row by inflating xml

Answer 1

I could manage to get an item of a ListView to be set as selected when long-clicked:

@Override
public boolean onItemLongClick(AdapterView<?> parent, View view,
        int position, long id) {
    parent.requestFocusFromTouch(); // IMPORTANT!
    parent.setSelection(position);
    return true;
}

It only worked after I called requestFocusFromTouch().
