A small framework to make using the 'ViewHolder' pattern a bit clearer

This branch is 4 commits behind rtyley:master

The aim is to reduce the boilerplate around writing your own ListAdapter class. With the library, you define two smaller classes, a ViewHolderFactory and a ViewHolder implementation.

Here's how you would set the adapter on your listView:

listView.setAdapter(new ViewHoldingListAdapter<Foo>(fooList, viewInflatorFor(context, foo_list_item), new ViewHolderFactory<Foo>() {
    public ViewHolder<Foo> createViewHolderFor(View view) {
    return new FooViewHolder(view);

Your FooViewHolder just does the job of the ViewHolder - holds the references to the required Views, and populates those views with the relevant fields from you Foo:

public class FooViewHolder implements ViewHolder<Foo> {
    private final TextView fooName,fooDate;
    private final ImageView icon;

    public FooViewHolder(View v) {
    this.avatarSession = avatarSession;
    fooName = (TextView) v.findViewById(;
    fooDate = (TextView) v.findViewById(;
    icon = (ImageView) v.findViewById(;

    public void updateViewFor(Foo foo) {
Something went wrong with that request. Please try again.
