Overview

Path 2.0 like ScrollBarPanel for Android

Android-ScrollBarPanel allows to attach a View to a scroll indicator like it's done in Path 2.0.

Features

Supports custom View as ScrollBarPanel.

Repository at https://github.com/rno/Android-ScrollBarPanel.

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.

Explain better the role of this widget

I am sure that this is a very nice widget. However, at the moment, your sole description is that it is "like Path", which will only make sense to people who use that app. Not everybody uses Path. For example, I do not use Path. Hence, I have no idea what your widget does that is not already handled by SectionIndexer in the SDK.

IMHO, adding a few sentences to the README explaining the widget's behavior and its use cases will make it easier for developers to determine whether or not your widget meets their particular needs.

Here's i've moved the OnScrollListener onto the ListView itself, should be a bit quicker.

I've also added a new type of Listener that doesn't fire every scroll event.

Some optimisations I've added:

Added a new listener called OnPositionChangedListener, instead of use OnScrollListener. onPositionChanged(...) is called only when the first visible item has changed

Other small optimisations

Added a .gitignore (same as the one I use on PtR).
