Implement RecyclerView Adapter with minimum complexity

Reduce Adapter creation speed to two methods.

Getting Started

To start working with dropdown, you need to add its dependency into your build.gradle file:

Dependency

dependencies {
    implementation "com.github.abbasghasemi:easy-recyclerview-adapter:[latest_version]"
}

Sample

There is a sample module.

Single view type

ItemAdapter(items, object : ItemAdapter.ViewBinding<ItemRecycler1Binding, DataModel> {
    override fun createItem(inflater: LayoutInflater, parent: ViewGroup, itemType: Int): ItemAdapter.Binding<ItemRecycler1Binding> {
        val item = ItemRecycler1Binding.inflate(inflater, parent, false)
        return ItemAdapter.Binding(item.root, item)
    }

    override fun bindItem(view: ItemRecycler1Binding, item: DataModel, position: Int, itemType: Int): Boolean {
        view.sample1.text = item.data
        return true
    }
})

Custom view type:

ItemAdapter(items, object : ItemAdapter.ViewBinding<Any, DataModel> {
    override fun itemType(position: Int): Int {
        return position
    }

    override fun createItem(inflater: LayoutInflater, parent: ViewGroup, itemType: Int): ItemAdapter.Binding<Any> {
        return if (itemType == 0) {
            val item = ItemRecycler1Binding.inflate(inflater, parent, false)
            ItemAdapter.Binding(item.root, item)
        } else {
            val item = ItemRecycler2Binding.inflate(inflater, parent, false)
            ItemAdapter.Binding(item.root, item)
        }
    }
    
    @Keep
    fun bindItem(view: ItemRecycler1Binding, item: DataModel, position: Int) {
        view.sample1.text = item.data
    }

    @Keep
    fun bindItem(view: ItemRecycler2Binding, item: DataModel, position: Int) {
        view.sample2.text = item.data
    }
})

Methods:

    animateTo(newItems) //Display new list changes with animation

    enableLongPressDrag(recyclerView,longPressDragListener) //The user can move items from one position to another

    insertItems(newItems)

    insertIgnoreItems(items)

    clearItems()
    
    clearAndInsertItems(newItems)

    insertItem(item)

    updateItem(position,item)

    removeItem(position)

    moveItem(fromPosition,toPosition)
    
    swapItem(fromPosition,toPosition)
