Hi,

I am trying to have different layout's for child view. But it keeps popping either the first layout or header view.
This is the adapter class

Hi,Here is wrong in your code.

  override fun getChildItemViewType(groupPosition: Int, childPosition: Int): Int {
        if (groupPosition == 0)
            return super.getChildItemViewType(groupPosition, VIEW_OFFER)
        if (groupPosition == 1)
            return super.getChildItemViewType(groupPosition, VIEW_PROPERTY)
        if (groupPosition == 2)
            return super.getChildItemViewType(groupPosition, VIEW_CLASS)
        if (groupPosition == 3)
            return super.getChildItemViewType(groupPosition, VIEW_PAYMENT)
        return super.getChildItemViewType(groupPosition, childPosition)
    }

I thought it's maybe.

  override fun getChildItemViewType(groupPosition: Int, childPosition: Int): Int {
        if (groupPosition == 0)
            return VIEW_OFFER
        if (groupPosition == 1)
            return VIEW_PROPERTY
        if (groupPosition == 2)
            return VIEW_CLASS
        if (groupPosition == 3)
            return VIEW_PAYMENT
        throw RuntimeException("unknow type") 
    }

Note this. Group 's viewType must be positive .Child 's viewType must be negative or zero. You also can change that by overwrite function isGroup.

    /**
     * Distinguish group item or child item by viewType.
     * By default groupViewType is positive , childViewType is negative or zero.
     */
    open fun isGroup(viewType: Int): Boolean = viewType > 0
