Small Android Library that let Developers write their own list adapters without copying code from previous projects

WonderAdapter

How many times do you copy ArrayAdapter, CursorAdapter and ViewHolders code? I've developed this library based mostly on the idea of UniversalAdapter library, but I've implemented a few improvements like ViewHolder pattern, multi view and cursor compatibility.

Usage

You just have to use the adapter that fits better to your needs. For now, there are only 3 wonder adapters you can use:

• WArrayAdapter
• WBaseAdapter
• WCursorAdapter

Steps to use any of these adapters within a ListView:

1. Create Custom Holder and let implement SingleWonder, MultiWonder or CursorWonder depending on the Adapter we want to use with. ..* T is the class of the item we want to show. ..* W the Holder class.
2. Basic methods to implement (on single views): ..* W newInstance() returns an instance of W(holder) for every row in the list. Our holder contains row view fields initialized. ..* void bind(...) needed to draw desired object fields on the initialized view fields contained inside our class W. ..* View inflateView(...) needs explanation? :-).

Example: ListView with array list of items within a single row view

WArrayAdapter<Wonder, SingleViewHolder> adapter = new WArrayAdapter(this, getData(cursor), new SingleViewHolder());
listView.setAdapter(adapter);

and our SingleViewHolder implementation:

public class SingleViewHolder implements SingleWonder<Wonder, SingleViewHolder> {

  // UI
  @InjectView(R.id.row_wonder_image) ImageView imageView;
  @InjectView(R.id.row_wonder_title) TextView titleView;

  @Override public SingleViewHolder newInstance() {
    return new SingleViewHolder();
  }

  @Override public void bind(Context context, Wonder item) {
    Picasso.with(context).load(item.getImage()).into(imageView);
    titleView.setText(item.getTitle());
  }

  @Override public View inflateView(LayoutInflater inflater, ViewGroup parent) {
    View view = inflater.inflate(R.layout.row_wonder, parent, false);
    ButterKnife.inject(this, view);
    return view;
  }

}

I've used Jake Wharton's Butterknife library to avoid using findViewById on every view in our row layout :-)

TODO'S

• CursorAdapter with multiple views support
• My WMultiArrayAdapter extends Object for a reason. It's very possible to draw our headers from another list (having two separated array lists or more, depending the number of custom view rows we would like to use) I can discuss whether use Generics or Object...
• I have to study carefully how to interact with other libraries, like StickyListHeaders, pinned-section-listview and other multi view ones.
