所以我有两个数据类（OutletListDataClass和ProductListDataClass），它们目前被两个不同的片段（OutletListFragment.kt和ProductListFragment.kt，在导航图中直接连接）使用。
这两个片段都是OutletListFragment.kt中的clicked item，我想从OutletListFragment.kt中提取信息（包含在两个数据类中），并将其传递给ProductListFragment.kt。
以下是我在两个片段中使用的数据类：

OutletListDataClass

data class OutletListPOJODataClasses(

    @SerializedName("data")
    @Expose
    var data: List<OutletListPOJODataClassesDataItem>? = null,

    @SerializedName("error")
    val error: OutletListDataClassError? = null
)


data class OutletListPOJODataClassesDataItem(
    @SerializedName("stk_prodcode")//Both data classes have this variable
    @Expose
    val stkProdcode: String? = null,

    @SerializedName("stk_allqty")
    @Expose
    val stkAllqty: Int? = null,

    @SerializedName("skt_lastupdate")
    @Expose
    val sktLastupdate: String? = null,

    @SerializedName("outlet_address")
    @Expose
    val outletAddress: String? = null,

    @SerializedName("outlet_name")
    @Expose
    val outletName: String? = null,

    @SerializedName("stk_outcode")
    @Expose
    val stkOutcode: String? = null
)

字符串

ProductListDataClass

data class ProductListPOJODataClasses(

    @field:SerializedName("data")
    val data: List<ProductListPOJODataClassesDataItem?>? = null,

    @field:SerializedName("error")
    val error: ProductListDataClassError? = null
)

data class ProductListDataClassError(

    @field:SerializedName("msg")
    val msg: String? = null,

    @field:SerializedName("code")
    val code: Int? = null,

    @field:SerializedName("status")
    val status: Boolean? = null
)

data class ProductListPOJODataClassesDataItem(
    @field:SerializedName("stk_prodcode")  //Both data classes have this variable
    val stkProdcode: String? = null,

    @field:SerializedName("stk_allqty")
    val stkAllqty: Int? = null,

    @field:SerializedName("pro_saleprice")
    val proSaleprice: Int? = null,

    @field:SerializedName("skt_lastupdate")
    val sktLastupdate: String? = null,

    @field:SerializedName("stk_outcode")
    val stkOutcode: String? = null,

    @field:SerializedName("pro_name")
    val proName: String? = null
)

正如你所看到的，这两个数据类包含sa.me变量（StkOutcode）。这就是我想要提取的（从OutletListDataItem）
下面是当前OutletListFragment.kt的代码片段：

override fun onCreateView(
    inflater: LayoutInflater, container: ViewGroup?,
    savedInstanceState: Bundle?
): View? {

    (activity as AppCompatActivity).supportActionBar?.title = "Product List"

    binding = DataBindingUtil.inflate(
        inflater,
        R.layout.fragment_product_stock_outlet_list,
        container,
        false
    )

    //Show Progressbar While loading data
    showProgressBar()

    //Apply layout manager
    binding.rvOutletList.layoutManager = LinearLayoutManager((activity as AppCompatActivity))

    //Fetch Outlet List Data
    fetchOutletListData()

    // Declare that this fragment has menu
    setHasOptionsMenu(true)

    // Set action bar title to "Outlet List"
    (activity as AppCompatActivity).supportActionBar?.title = "Outlet List"

    return binding.root
}

型
这是我为OutletListFragment创建的Clerclerview适配器。OutletListAdapter

class OutletListItemHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {

    fun bind(
        outlet: OutletListPOJODataClassesDataItem,
        clickListener: OutletListOnItemClickListener?
    ) {
        itemView.outletName.text = outlet.outletName

        itemView.setOnClickListener {
            clickListener?.onItemClicked(outlet)
        }
    }
}

class OutletListAdapter(private var outletList: OutletListPOJODataClasses, private val itemClickListener: OutletListOnItemClickListener)
: RecyclerView.Adapter<OutletListItemHolder>() {

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): OutletListItemHolder {
        val v = LayoutInflater.from(parent.context).inflate(R.layout.outlet_list_item_layout, parent, false)
        return OutletListItemHolder(v)
    }

    override fun getItemCount(): Int = outletList.data!!.size

    override fun onBindViewHolder(holder: OutletListItemHolder, position: Int) {
        val outlet = outletList.data?.get(position)
        if (outlet != null) {
            holder.bind(outlet, itemClickListener)
        }
    }
}

interface OutletListOnItemClickListener{
    fun onItemClicked(outlet: OutletListPOJODataClassesDataItem)
}

如何从OutletListFragment.kt中的Data类获取想要的变量并将其传递给ProductListFragment.kt？如果有任何不清楚的地方，请告诉我。

编辑：

以下是navigation.xml的代码片段：

<fragment
    android:id="@+id/productStockOutletList"
    android:name="something.mainFragments.ProductStockOutletListFragment"
    android:label="ProductStockOutletList" >
    <action
        android:id="@+id/action_productStockOutletList_to_productListFragment"
        app:destination="@id/productListFragment"
        app:enterAnim="@android:anim/slide_in_left"
        app:exitAnim="@android:anim/slide_out_right"
        app:popEnterAnim="@android:anim/slide_in_left"
        app:popExitAnim="@anim/slide_out_left" />
</fragment>

<fragment
    android:id="@+id/productListFragment"
    android:name="something.mainFragments.ProductListFragment"
    android:label="ProductListFragment" />
