Summary

Public constructors
`SortedListAdapterCallback(Adapter adapter)` Creates a `SortedList.Callback` that will forward data change events to the provided Adapter.

Public methods
`void`	`onChanged(int position, int count, Object payload)` Called when `count` number of items are updated at the given position.
`void`	`onChanged(int position, int count)` Called by the SortedList when the item at the given position is updated.
`void`	`onInserted(int position, int count)`
`void`	`onMoved(int fromPosition, int toPosition)`
`void`	`onRemoved(int position, int count)`

From class


        
          androidx.recyclerview.widget.SortedList.Callback

`abstract boolean`	`areContentsTheSame(T2 oldItem, T2 newItem)` Called by the SortedList when it wants to check whether two items have the same data or not.
`abstract boolean`	`areItemsTheSame(T2 item1, T2 item2)` Called by the SortedList to decide whether two objects represent the same Item or not.
`abstract int`	`compare(T2 o1, T2 o2)` Similar to `Comparator.compare(Object, Object)`, should compare two and return how they should be ordered.
`Object`	`getChangePayload(T2 item1, T2 item2)` When `areItemsTheSame(T2, T2)` returns `true` for two items and `areContentsTheSame(T2, T2)` returns false for them, `SortedList.Callback` calls this method to get a payload about the change.
`void`	`onChanged(int position, int count, Object payload)` Called when `count` number of items are updated at the given position.
`abstract void`	`onChanged(int position, int count)` Called by the SortedList when the item at the given position is updated.
