Usage

Layout

<!--
  The ExtendedListView replaces a standard ListView widget
  and provides the ScrollBarPanel capability.
-->
<com.dafruits.android.library.widgets.ExtendedListView
    xmlns:dafruits="http://schemas.android.com/apk/res/YOUR_APP_PACKAGE_NAME"
    android:id="@android:id/list"
    android:layout_height="fill_parent"
    android:layout_width="fill_parent"
    dafruits:scrollBarPanel="@layout/YOUR_SCROLLBARPANEL_LAYOUT"
    dafruits:scrollBarPanelInAnimation="@anim/YOUR_ANIMATION"
    dafruits:scrollBarPanelOutAnimation="@anim/YOUR_ANIMATION" />

Activity

// Set your scrollBarPanel
ExtendedListView listView = (ExtendedListView) findViewById(android.R.id.list);

// Attach a position changed listener on the listview and play with your scrollBarPanel
// when you need to update its content
mListView.setOnPositionChangedListener(new OnPositionChangedListener() {

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

Pull Requests

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.
