最近我注意到我的应用程序中有一个问题，当我关闭viewAllfragment并再次重新打开它时，我看到列表一次又一次地重复，每次都有相同的数据，我试图在片段被销毁时清除列表，并仅在适配器为空时提交数据，但所有这些都没有解决这个问题
这就是XML

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".ui.view_all.ViewAllFragment">

    <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/recyclerView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:visibility="gone"
        android:background="@color/lightGray"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <GridView
        android:id="@+id/gridView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/lightGray"
        android:verticalSpacing="1dp"
        android:horizontalSpacing="1dp"
        android:visibility="gone"
        tools:visibility="visible"
        android:numColumns="auto_fit"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>

这个GridProductAdapter代码

class GridProductAdapter : BaseAdapter() {

    private var productScrollModelList = arrayListOf<HorizontalProductScrollModel>()

//    init {
//
//    }

    fun submitList(productScrollModelList: List<HorizontalProductScrollModel>){
        this.productScrollModelList.addAll(productScrollModelList)
        notifyDataSetChanged()

        Log.d(TAG, "submitList: size ${productScrollModelList.size}")
    }

    fun clearList(){
        this.productScrollModelList.clear()
        notifyDataSetChanged()
    }

    override fun getCount(): Int {
        return productScrollModelList.size
    }

    override fun getItem(i: Int): Any? {
        return null
    }

    override fun getItemId(i: Int): Long {
        return 0
    }

    override fun getView(position: Int, convertView: View?, parent: ViewGroup): View {

        var localConvertView: View? = convertView

        val binding: HorizontalScrollItemLayoutBinding

        if (localConvertView == null) {
            binding = HorizontalScrollItemLayoutBinding.inflate(
                LayoutInflater.from(parent.context)
            )
            localConvertView = binding.root
            localConvertView.setTag(R.id.viewBinding, binding)
        } else {
            binding = localConvertView.getTag(R.id.viewBinding) as HorizontalScrollItemLayoutBinding
        }

//        binding.hsProductImage.setImageResource(productScrollModelList.get(position).getProductImage());
        Glide.with(binding.root.context)
            .load(productScrollModelList[position].productImage)
            .placeholder(R.drawable.placeholder_image)
            .into(binding.hsProductImage)
        binding.hsProductName.text = productScrollModelList[position].productName
        binding.hsProductDescription.text = productScrollModelList[position].productDescription
        binding.hsProductPrice.text = "Rs.${productScrollModelList[position].productPrice}/-"

//        binding.getRoot().setOnClickListener(new View.OnClickListener() {
//            @Override
//            public void onClick(View view) {
//
//            }
//        });
        return localConvertView
    }
}

我在viewAllfragment中使用它，如下所示

private var _binding: FragmentViewAllBinding? = null
    private val binding get() = _binding!!

    private val LAYOUT_CODE = 0
    private val wishList= arrayListOf<WishListModel>()

    private val wishlistAdapter = WishlistAdapter(false)

    private val args by navArgs<ViewAllFragmentArgs>()

    private var layoutCode:Int =0

    private val gridProductAdapter by lazy { GridProductAdapter()  }

    override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View {
        _binding = FragmentViewAllBinding.inflate(inflater)

        layoutCode = args.layoutCode
        (requireActivity() as MainActivity).fragmentTitleAndActionBar(args.title)

        return binding.root
    }

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)


        if(layoutCode == 0) {

            wishList.addAll(args.viewAllProductList!!)

            wishlistAdapter.asyncListDiffer.submitList(wishList)
//            wishlistAdapter.submitList(wishList)

            binding.recyclerView.apply {
                visibility = View.VISIBLE
                layoutManager = LinearLayoutManager(requireContext(),LinearLayoutManager.VERTICAL,false)
                adapter = wishlistAdapter
            }

        }else if(layoutCode == 1) {

            //================ Horizontal list ======================//

            binding.gridView.visibility = View.VISIBLE

            binding.gridView.adapter = gridProductAdapter

            Log.d(TAG, "onViewCreated: horizontalProductScrollModelList size ${args.horizontalProductScrollModelList.size}")

            if(gridProductAdapter.isEmpty) {
                gridProductAdapter.submitList(args.horizontalProductScrollModelList.toList())
            }
        }

    }

    override fun onDestroyView() {
        super.onDestroyView()
        gridProductAdapter.clearList()
        _binding = null
    }
