how can i automatically size listview so it doesn't scroll

Question

currently i have the following layout

Answer 1

Add a empty item on list end

Example:

ArrayList options = new ArrayList();
String lastItem = "";
int lastPosition;

options.add(lastItem);

public function addItem() {
    lastPosition = options.size() - 1;
    lastItem = options.get(lastPosition);
    options.remove(lastPosition);

    //add new items dynamically
    for (int i = 0; i < 5; i++) 
        options.add("new item: "+i);

    //add empty item
    options.add(lastItem);
}
