Scroll list view and detect the end- android

Question

I have a list view inside which a linear layout with lots of items. Now i want to have a imageview at the button stating scrolldown till the end of the scrollview is reached and once the end is reached to hide it self. Again once the user scrolls up, the imageview should re appear. Can anyone please tell how to detect the end of scrollview?? Searched several forums but they have given for listview, but i badly need for scroll view only. Please help!

Answer 1

You can detect the end of scrolling by the following code

if (yourListView.getLastVisiblePosition() == yourListView.getAdapter().getCount() -1 &&
    yourListView.getChildAt(yourListView.getChildCount() - 1).getBottom() <= yourListView.getHeight())
{
    //It is scrolled all the way down here

}

Hope it helps.

You have to check the array list count on getView(int position, View convertView, ViewGroup parent) method in BaseAdapter class

 public View getView(int position, View convertView, ViewGroup parent) {
    LayoutInflater inflater = (LayoutInflater) context
        .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View rowView = inflater.inflate(R.layout.rowlayout, parent, false);

    ImageView imageView = (ImageView) rowView.findViewById(R.id.icon);

    // Change the visibility here

     if(list.size >= position)
        imageView.setVisibility(View.Gone);
     else
        imageView.setVisibility(View.Visible);

    return rowView;
  }
