android RecyclerView嵌套 RecyclerView 子item 和 父item点击事件如何处理_recyclerview嵌套 recyclerview 点击事件

        this.setOnChildItemChildClick(view, index, position)
    }

    holder.setText(R.id.storeName, item.storeName)
    holder.getView<CheckBox>(R.id.storeCheckBox).isChecked = item.check!!
    holder.getView<RecyclerView>(R.id.goodsItemList).run {
        layoutManager = LinearLayoutManager(this.context)
        adapter = goodsListAdapter
        isNestedScrollingEnabled = false
    }
    goodsListAdapter.setList(item.goodsList)
}

protected open fun setOnChildItemChildClick(v: View, parent: Int, position: Int) {
    mOnChildItemChildClickListener?.onItemChildClick(this, v, parent, position)
}


open fun setOnChildItemChildClickListener(listener: OnChildItemChildClickListener) {
    this.mOnChildItemChildClickListener = listener
}

}

## 子adapter

class StoreGoodsListAdapter(layoutResId: Int, data: MutableList): BaseQuickAdapter<CartGoodsBean, BaseViewHolder>(layoutResId, data) {
private var imageLoader: ImageLoader = CoilUtil.getImageLoader()

override fun convert(holder: BaseViewHolder, item: CartGoodsBean) {
    holder.getView<ImageView>(R.id.cartGoodsImg).load(item.imgUrl, imageLoader ) {
        crossfade(true)
        placeholder(R.drawable.default_img)
        error(R.drawable.default_img)
    }

    holder.getView<CheckBox>(R.id.goodsCheckBox).isChecked = item.check!!
    holder.setText(R.id.cartGoodsDes, item.description)
    holder.setText(R.id.cartGoodsPrice, "￥${item.price}")
}

}

## listener

open interface OnChildItemChildClickListener {
fun onItemChildClick(adapter: BaseQuickAdapter<*, *>, view: View, parentPosition: Int, position: Int)
}

## 页面上监听

//点击店铺前的checkbox
cartGoodsListAdapter.setOnItemChildClickListener { _, view, position ->
when (view.id) {
R.id.storeCheckBox -> checkAllByStore(position)
}
}
//点击店铺中商品前的checkbox
cartGoodsListAdapter.setOnChildItemChildClickListener(object : OnChildItemChildClickListener {
override fun onItemChildClick(
adapter: BaseQuickAdapter<*, *>,
view: View,
parentPosition: Int,
position: Int,
) {
when (view.id) {
R.id.goodsCheckBox -> checkGoods(parentPosition, position)
}
}
})
