To implement a RecyclerView with multiple view types in Android, you can follow these steps:
getItemViewType()
method in your RecyclerView adapter. This method determines the view type for a given item position. You can use the position or the item’s data to decide which view type to return. Typically, you would return an integer representing the view type.onCreateViewHolder()
method in your RecyclerView adapter. Inside this method, inflate the appropriate layout based on the view type. You can use the view type parameter to determine which layout to inflate.onBindViewHolder()
method in your RecyclerView adapter. Here, you need to handle binding the data to the appropriate views based on the view type. Use the item’s view holder to access the correct views and set their values accordingly.By following these steps, your RecyclerView adapter will be able to handle multiple view types. It will inflate the correct layout for each item and bind the corresponding data to the appropriate views. This allows you to have a dynamic and flexible RecyclerView that supports different layouts for different types of items.
The steps below must be followed in order to construct a RecyclerView in Android with various view types:
Establish view types: Choose the various view types you wish to show in the RecyclerView. A distinctive (integer value) identification for each view type is required.
Create a RecyclerViewAdapter by extending RecyclerView with a unique RecyclerViewAdapter.Adapter. This adaptor will take care of the logic for tying together various view kinds.
Make classes for view holders: For each sort of view, create a unique ViewHolder class. Each ViewHolder should provide pointers to the views in its respective layout and extend RecyclerView.ViewHolder.
Replace get Item View Type: Replace the get Item View Type method in the RecyclerViewAdapter. Based on an item’s position, this method will return the view type for that item
