using custome list row presenter

class CustomListRowPresenter : ListRowPresenter(FocusHighlight.ZOOM_FACTOR_NONE, true) {

override fun initializeRowViewHolder(holder: RowPresenter.ViewHolder) {
    super.initializeRowViewHolder(holder)
    val vh = (holder as ViewHolder)
    val mContainerViewHolder =
        (RowPresenter.ViewHolder::class.java).getDeclaredField("mContainerViewHolder")
    mContainerViewHolder.isAccessible = true
    val viewHolder = mContainerViewHolder.get(vh) as Presenter.ViewHolder
    val nonOverlappingLinearLayout =
        (viewHolder.view as ViewGroup).children.find { it is NonOverlappingLinearLayout }
    if (nonOverlappingLinearLayout != null) {
        val left = 0
        val right = nonOverlappingLinearLayout.right
        val top = nonOverlappingLinearLayout.top
        val bottom = nonOverlappingLinearLayout.bottom
        nonOverlappingLinearLayout.setPadding(left, top, right, bottom)
    }
    val headerHolder = vh.headerViewHolder
    headerHolder.selectLevel
    val field = vh::class.java.getDeclaredField("mPaddingLeft")
    field.isAccessible = true
    field.set(vh, 0)
