Code Comparison

MultiType:

class TextItemViewBinder : ItemViewBinder<String, TextItemViewBinder.ViewHolder>() {
    override fun onCreateViewHolder(inflater: LayoutInflater, parent: ViewGroup): ViewHolder {
        return ViewHolder(inflater.inflate(R.layout.item_text, parent, false))
    }
    override fun onBindViewHolder(holder: ViewHolder, item: String) {
        holder.textView.text = item
    }
    class ViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
        val textView: TextView = itemView.findViewById(R.id.text)
    }
}

Epoxy:

@EpoxyModelClass(layout = R.layout.item_text)
abstract class TextItemModel : EpoxyModelWithHolder<TextItemModel.Holder>() {
    @EpoxyAttribute lateinit var text: String
    override fun bind(holder: Holder) {
        holder.textView.text = text
    }
    class Holder : EpoxyHolder() {
        lateinit var textView: TextView
        override fun bindView(itemView: View) {
            textView = itemView.findViewById(R.id.text)
        }
    }
}

Pros of AdapterDelegates

• More flexible delegation system, allowing for easier composition of complex adapters
• Better support for inheritance and subclassing of delegate types
• Cleaner separation of concerns between item types and their corresponding views

Cons of AdapterDelegates

• Slightly more verbose implementation, requiring more boilerplate code
• Less intuitive for simpler use cases with fewer item types
• Steeper learning curve for developers new to the delegate pattern

Code Comparison

MultiType:

class TextItemViewBinder : ItemViewBinder<TextItem, TextItemViewBinder.ViewHolder>() {
    override fun onCreateViewHolder(inflater: LayoutInflater, parent: ViewGroup): ViewHolder {
        return ViewHolder(inflater.inflate(R.layout.item_text, parent, false))
    }
    override fun onBindViewHolder(holder: ViewHolder, item: TextItem) {
        holder.textView.text = item.text
    }
}

AdapterDelegates:

class TextAdapterDelegate : AdapterDelegate<List<Any>>() {
    override fun isForViewType(items: List<Any>, position: Int): Boolean {
        return items[position] is TextItem
    }
    override fun onCreateViewHolder(parent: ViewGroup): RecyclerView.ViewHolder {
        return TextViewHolder(LayoutInflater.from(parent.context).inflate(R.layout.item_text, parent, false))
    }
    override fun onBindViewHolder(items: List<Any>, position: Int, holder: RecyclerView.ViewHolder, payloads: List<Any>) {
        val textItem = items[position] as TextItem
        (holder as TextViewHolder).textView.text = textItem.text
    }
}

Pros of FastAdapter

• More comprehensive feature set, including drag & drop, swipe-to-dismiss, and expandable items
• Extensive documentation and sample apps for easier implementation
• Built-in support for different view types and layouts

Cons of FastAdapter

• Steeper learning curve due to its extensive API and features
• Potentially higher memory footprint for simple use cases
• More complex setup process compared to MultiType

Code Comparison

MultiType:

class TextItemViewBinder : ItemViewBinder<TextItem, TextItemViewBinder.ViewHolder>() {
    override fun onCreateViewHolder(inflater: LayoutInflater, parent: ViewGroup): ViewHolder {
        return ViewHolder(inflater.inflate(R.layout.item_text, parent, false))
    }
    override fun onBindViewHolder(holder: ViewHolder, item: TextItem) {
        holder.textView.text = item.text
    }
}

FastAdapter:

class TextItem : AbstractItem<TextItem.ViewHolder>() {
    override val layoutRes: Int = R.layout.item_text
    override val type: Int = R.id.fastadapter_text_item
    override fun getViewHolder(v: View): ViewHolder = ViewHolder(v)
    class ViewHolder(view: View) : FastAdapter.ViewHolder<TextItem>(view) {
        val textView: TextView = view.findViewById(R.id.text)
    }
}

Both libraries offer efficient ways to handle multiple view types in RecyclerViews, but FastAdapter provides more built-in features at the cost of increased complexity. MultiType focuses on simplicity and flexibility, making it easier to use for basic scenarios.

Pros of SectionedRecyclerViewAdapter

• Built-in support for section headers and footers
• Easier management of complex, sectioned layouts
• Provides helper methods for section-specific operations

Cons of SectionedRecyclerViewAdapter

• More complex API, steeper learning curve
• Less flexible for non-sectioned layouts
• Potentially higher memory usage due to section management

Code Comparison

SectionedRecyclerViewAdapter:

SectionedRecyclerViewAdapter sectionAdapter = new SectionedRecyclerViewAdapter();
sectionAdapter.addSection(new MySection());
recyclerView.setAdapter(sectionAdapter);

MultiType:

MultiTypeAdapter adapter = new MultiTypeAdapter();
adapter.register(Item.class, new ItemViewBinder());
recyclerView.setAdapter(adapter);

SectionedRecyclerViewAdapter is designed specifically for sectioned layouts, providing built-in support for headers and footers. It offers easier management of complex, sectioned data structures and includes helper methods for section-specific operations.

However, SectionedRecyclerViewAdapter has a more complex API and a steeper learning curve compared to MultiType. It's less flexible for non-sectioned layouts and may have higher memory usage due to its section management system.

MultiType, on the other hand, offers a simpler and more flexible approach for handling multiple view types. It's easier to use for general-purpose RecyclerView implementations but requires more manual work for implementing sectioned layouts.

The code comparison shows that SectionedRecyclerViewAdapter requires creating section objects, while MultiType uses a more straightforward registration of item types and binders.

        holder.text.text = item.text
    }
    class Holder(itemView: View) : RecyclerView.ViewHolder(itemView) {
        val text: TextView = itemView.findViewById(R.id.text)
    }
}

FlexibleAdapter:

class TextItem(val text: String) : AbstractFlexibleItem<TextItem.ViewHolder>() {
    override fun bindViewHolder(adapter: FlexibleAdapter<*>, holder: ViewHolder, position: Int, payloads: List<*>) {
        holder.text.text = text
    }
    override fun createViewHolder(view: View, adapter: FlexibleAdapter<*>): ViewHolder {
        return ViewHolder(view, adapter)
    }
    class ViewHolder(view: View, adapter: FlexibleAdapter<*>) : FlexibleViewHolder(view, adapter) {
        val text: TextView = view.findViewById(R.id.text)
    }
}
