Simply ,Add data in your ArrayList which you are passing in adapter constructor. After then call adapter.notifyDataSetChanged() .If you face problem with listview height ,then set it dynamically on button click -

public static void setListViewHeightBasedOnChildren(ListView listView) {
ListAdapter listAdapter = listView.getAdapter();
if (listAdapter == null)
    return;

int desiredWidth = MeasureSpec.makeMeasureSpec(listView.getWidth(), MeasureSpec.UNSPECIFIED);
int totalHeight = 0;
View view = null;
for (int i = 0; i < listAdapter.getCount(); i++) {
    view = listAdapter.getView(i, view, listView);
    if (i == 0)
        view.setLayoutParams(new ViewGroup.LayoutParams(desiredWidth, LayoutParams.WRAP_CONTENT));

    view.measure(desiredWidth, MeasureSpec.UNSPECIFIED);
    totalHeight += view.getMeasuredHeight();
}
ViewGroup.LayoutParams params = listView.getLayoutParams();
params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
listView.setLayoutParams(params);
}
