Least

Least amount of effort to add multiple views in a recyclerview.

LeastAdapter

        //adapter builder
        LeastAdapter adapter = new LeastAdapter.Builder()

                // 1) bind the view types you want to display
                .binder(new UserBinder(User.class, UserViewHolderHolder.class, R.layout.layout_user))
                .binder(new BannerBinder(Banner.class, BannerViewHolderHolder.class, R.layout.layout_banner))
                .binder(new HeaderBinder(String.class, HeaderViewHolder.class, R.layout.layout_header))

                // 2) add your list items
                .item("Section 1")
                .items(getUsers())

                .item("Section 2")
                .items(getBanners())

                .item("Section 3")
                .items(getUsers())

                // 3) done
                .build(this);

Details

The idea is that you bind an object class to a viewholder. The object class is your typical list item e.g User.class

Let's say you want to display 3 different kind of views. A user view, a banner view and a header view.

First step

Create a binder for each view type by extending the Binder class, like so:

//Extend the binder by adding the viewholder and list item class of your view
public class UserBinder extends Binder<UserViewHolderHolder, User> {

    @Override
    public void onBindViewHolder(UserViewHolderHolder holder, User user, int position) {
        holder.textView.setText(user.getName());
    }
}

Do the same for your other views

Last step

That's pretty much it. Just use the binder to your adapter like so:

//set the list item class, viewholder class and the view layout id
UserBinder userBinder = new UserBinder(User.class, UserViewHolderHolder.class, R.layout.layout_user)

new LeastAdapter.Builder()
                .binder(userBinder)
                ...
                //add more views

Proguard

-keep class * extends io.c0nnector.github.least.Binder { *; }

Install

1. Add it in your build.gradle at the end of repositories:

repositories { maven { url "https://jitpack.io" } }

2. Add the dependency in the form

implementation 'com.github.ArthurSav:Least:master-SNAPSHOT'
