• Supports custom View as ScrollBarPanel.

  The ExtendedListView replaces a standard ListView widget
  and provides the ScrollBarPanel capability.

// Set your scrollBarPanel

// Attach a position changed listener on the listview and play with your scrollBarPanel

mListView.setOnPositionChangedListener(new OnPositionChangedListener() {

	@Override
	public void onPositionChanged(ExtendedListView listView, int firstVisiblePosition, View scrollBarPanel) {
		((TextView) scrollBarPanel).setText("Position " + firstVisiblePosition);
	}
});

I will gladly accept pull requests for fixes and feature enhancements but please do them in the dev branch. The master branch is for the latest stable code, dev is where I try things out before releasing them as stable. Any pull requests that are against master from now on will be closed asking for you to do another pull against dev.
