How to set the height of an item row in GridLayoutManager

Question

My Recycler Item which inflate in onCreateViewHolder

Answer 1

kotlin version

override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
    val binding = ItemBinding.inflate(
        LayoutInflater.from(parent.context),
        parent,
        false
    )
    binding.root.post {
        binding.root.layoutParams.height = parent.width/3
        binding.root.requestLayout()
    }
    return ViewHolder(binding)
}

here 3 is the span count of your GridLayoutManager . You can replace binding.root with your itemView , if you are not using Databinding
