Any idea about how to correct apply GridLayoutManager

[leopku]

Is your feature request related to a problem?
Thanks for your many useful projects.

I wanna apply GridLayoutManager like below:

section1
item1 item2 item3
item4 item5 item6
section2
item21 item22 item23
item24 item25 item26

If using GridLayoutMananger directly, result would like below:

section1 item1 item2
item3 section2 item21
item22 item23

Any idea about it?

Hi, @leopku
In that case, you should use the RecyclerView with LinearLayour, and add a second RecyclerView with GridLayoutManager in the item layout. (not section's header layout).

Here is some examples using SampleAdapter and SampleViewHolder.

  override fun layout(sectionRow: SectionRow): Int {
    when (sectionRow.row) {
      0 -> return R.layout.item_sample1_header
      else -> return R.layout.item_sample
    }
  }

The R.layout.item_sample shoud be like below.

<?xml version="1.0" encoding="utf-8"?>
<androidx.recyclerview.widget.RecyclerView 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginBottom="10dp" />

Make a new adapter and viewholder for the grid item. (ItemDetailAdapter, ItemDetailViewHolder).

After that, here is an example of the SampleViewHolder.

itemView.run {
      recyclerView.adapter = ItemDetailAdapter()
      recyclerView.layoutManager = GridLayoutManager(context(), 3)
      // add items
    }

Thank you for your issue :)
