### setViewTypeCount

Added in[API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)  

```
fun setViewTypeCount(viewTypeCount: Int): RemoteViews.RemoteCollectionItems.Builder
```

Sets the view type count for the collection when used in an adapter. This can be set to the maximum number of different layout ids that will be used by RemoteViews in this collection. If this value is not set, then a value will be inferred from the provided items. As a result, the adapter may need to be recreated when the list is updated with previously unseen RemoteViews layouts for new items.
