4.3.2

What's Changed

• More nullability annotations for better inter-op with Kotlin #107 . This should not be a breaking change.

4.3.1

Addition: get notified when list was committed to RecyclerView #104

4.3.0

• Support for android ViewBinding. Use adapterDelegateViewBinding().
• Fix #81 . LayoutContainer support for libraries.

4.2.0

Minor improvements:

• add vararg delegate parameter to AsyncListDifferDelegationAdapter #76
• DslListAdapterDelegate is internal no (with @PublishedApi)
• Fixed 2 internal typos on variable names

4.1.1

Added some shortcuts / convenience functions (and properties) for kotlin DSL. Instead of calling itemView.context you now have direct access to the following fields and functions:

• context (backed property)
• getString(@StringRes resId: Int): String
• getString(@StringRes resId: Int, vararg formatArgs: Any)
• getColor(@ColorRes id: Int)
• getDrawable(@DrawableRes id: Int)
• getColorStateList(@ColorRes id: Int)

Overall this minor release just reduces a bit more typing for you as you now can do something like this:

fun catDelegate() = adatperDelegate<Cat, Animal>(R.layout.cat) {
   ...
   bind {
        icon.drawable = getDrawable(R.drawable.cat) // instead of itemView.context.getDrawable()
   }
}

4.1.0: Kotlin DSL

Added a Kotlin DSL to create AdapterDelegates through a fluend DSL. There are actually 2 DSL artifacts:

• adapterdelegates4-kotlin-dsl:

fun catAdapterDelegate(itemClickedListener : (Cat) -> Unit) = adapterDelegate<Cat, Animal>(R.layout.item_cat) {
    val name : TextView = findViewById(R.id.name)
    name.setClickListener { itemClickedListener(item) }

    bind { 
        name.text = item.name 
    }
}

• adapterdelegates4-kotlin-dsl-layoutcontainer:
  Pretty much the same as adapterDelegate but uses kotlin android extension's LayoutContainer and the generated synthetic properties. Thus, you dont have to write any findViewById().

fun catAdapterDelegate(itemClickedListener : (Cat) -> Unit) = adapterDelegateLayoutContainer<Cat, Animal>(R.layout.item_cat) {
    name.setClickListener { itemClickedListener(item) } // name is imported from kotlinx.android.synthetic.main.item_cat.name

    bind { 
        name.text = item.name 
    }
}

Read the README for more details how to use it.

4.0.0

• Uses RecyclerView from AndroidX: androidx.recyclerview:recyclerview:1.0.0
• Package name changed from adapterdelegates3 to adapterdelegates4

3.1.0

Added AsyncListDifferDelegationAdapter that uses DiffUtils under the hood to animate dataset changes.

3.0.1

• Minor bugfix (kotlin null safety) that ensures that list of payloads in adapterDelegate.onBindViewHoler() is never null (empty list if payload not used) #30
• JavaDoc update #28

3.0.0

• AdapterDelegate is now an abstract class (was a interface formerly)
• Added the following methods to AdapterDelegate:
  • onBindViewHolder(@NonNull T items, int position, @NonNull RecyclerView.ViewHolder holder, @NonNull List<Object> payloads);: This method will be called for both adapter.notifyItemChanged() with or without payload. In Version 2.x of this library there was only one method onBindViewHolder(@NonNull T items, int position, @NonNull RecyclerView.ViewHolder holder). This one (with additional payload parameter) replaces the old one.
  • onViewRecycled(ViewHolder holder): Called when ViewHolder has been recycled
  • onFailedToRecycleView(ViewHolder holder): Called when ViewHolder couldn't be recycled
  • onViewAttachedToWindow(ViewHolder holder): Called when View (of ViewHolder) has been attached to window
  • onViewDetachedFromWindow(ViewHolder holder): Called when View (of ViewHolder) has been detached from window
• changed visibility modifiers of methods of AdapterDelegate to protected (formerly public before because of interface)
