尝试在自定义布局中合并两个布局

我试图通过扩展线性布局将两个xml布局添加到一起,但没有得到预期的结果。当我将这个视图设置为RecyclerView时,我只得到标题行

我膨胀的两个XML布局都是线性布局,

class AddOnCardView : LinearLayout {

    private var itemData: AddOnCardData? = null

    constructor(context: Context) : this(context, null)
    constructor(context: Context, attrs: AttributeSet?) : this(context, attrs, 0)

    constructor(context: Context, attrs: AttributeSet?, defStyleAttr: Int) : super(context, attrs, defStyleAttr) {
        val header: LinearLayout = inflate(getContext(), R.layout.tw_dashboard_addon_header, this) as LinearLayout
        val childRow = inflate(getContext(), R.layout.tw_dashboard_addon_row, null)
        // prepareChildren(header)

        header.addView(childRow)
    }

    fun setDataItem(itemData: AddOnCardData) {
        this.itemData = itemData

    }


}
