Android ListView clicking bottom item and increasing height of it

Question

I have a listview where pople can click on items. When they do, they increase height and show more information.

However, when clicking the bottom item, it is not visible to the user that the item height has increased and there is content if you scroll down.

Using e.g. following code in onItemClick does not solve the problem:

    if (position == myItemsDataArrayList.size() - 1) {
      if (data.ui_flags == "clicked") {
        catalogListView.smoothScrollToPosition(position);
      }
    }

@androbat I will try out the solutions mentioned there. (However, I think one problem is that the item is already selected... Hence e.g. seting it selected won't help Android detect bottom item size increased and it needs to rescroll. That said, worth trying! Thanks!) — Tom, Aug 06 '13 at 18:56

Implement this function in your if statement.

private void scrollMyListViewToBottom() {
myListView.post(new Runnable() {
    @Override
    public void run() {
        // Select the last row so it will scroll into view...
        myListView.setSelection(myListAdapter.getCount() - 1);
    }
});
}

Working code solution was this:

catalogListView.post(new Runnable() {
  @Override
  public void run() { 
    catalogListView.setSelection(position_final);
  }
});
