RecyclerView LayoutManager different span counts on different rows

Question

I want a RecyclerView.LayoutManager that allows me to specify different span counts for different rows as a repeating pattern. For example 2,3 with 10 items wou

Answer 1

here's how to do it in kotlin:

val layoutManager= GridLayoutManager(activity, 3)
layoutManager.spanSizeLookup = object : GridLayoutManager.SpanSizeLookup() {
    override fun getSpanSize(position: Int): Int {
        return when (position) {
            0 -> 3
            else -> 1
        }
    }
}
recyclerView.layoutManager = layoutManager

here, first we have created a grid layout manager with 3 columns, then we have specified the first will occupy the whole 3 columns while the rest take only one.
