android – 如何在另一个recycleview适配器下的recycleview适配器？

我有一个RecyclerView.它有一个自定义布局,在自定义布局内是另一个RecyclerView.当我通知回收站视图项目已被删除时,我的主回收站视图已更新,但我的自定义视图回收视图未收到通知.

SwipedismissRecyclerViewTouchListener listener = new SwipedismissRecyclerViewTouchListener.Builder(
            recyclerView,new SwipedismissRecyclerViewTouchListener.dismissCallbacks() {
                @Override
                public boolean candismiss(int position) {

                    return true;
                }

                @Override
                public void ondismiss(View view) {
                    // Do what you want when dismiss
                    int id = recyclerView.getChildAdapterPosition(view);
                    databaseHelper.deleteSingleItem(cartAdapter.cartItemName.get(id));

                    Log.e(TAG,"ondismiss: " + subdata.get(id) + " " + data.get(id));
                    subdataprice.remove(id);
                    subdata.remove(id);
                    addonlist.remove(id);
                    price.remove(id);
                    data.remove(id);
                    cartAdapter.notifyItemRemoved(id);

                    Log.e(TAG,data.size() + " ondismiss: size " + subdata.size());
                    totalPriceTextView.setText(String.valueOf(getTotal()));
                    cartAdapter.updateRecycler();
                }
            })
            .setIsvertical(false)
            .setItemClickCallback(new SwipedismissRecyclerViewTouchListener.OnItemClickCallBack() {
                @Override
                public void onClick(int i) {
                    // Toast.makeText(getBaseContext(),String.format("Delete item"),Toast.LENGTH_LONG).show();

                }
            })
            .create();
    recyclerView.setonTouchListener(listener);

这是要删除的RecyclerView滑动的代码.在我的购物车适配器中我采取了另一个回收视图适应.任何想法如何通知自适应如果从循环视图中删除任何数据.???

我的onBindViewHolder类

@Override
public void onBindViewHolder(CustomViewHolder holder,int position) {

    try {
        holder.itemName.setText(String.format("%s",cartItemName.get(position)));
        holder.itemPrice.setText(String.format("£  %s",cartItemPrice.get(position)));

        AddonRecycleviewAdapter recycleViewAdapter = new AddonRecycleviewAdapter(context,listsubdata.get(position),listsubprice.get(position),listsubAddon.get(position));
        holder.addon_recycleview.setHasFixedSize(true);
        holder.addon_recycleview.setLayoutManager(new linearlayoutmanager(context,linearlayoutmanager.VERTICAL,false));
        holder.addon_recycleview.setAdapter(recycleViewAdapter);


    } catch (Exception e) {
        e.printstacktrace();
    }
}

家长回收视图

<android.support.v7.widget.RecyclerView
                android:id="@+id/cartRecyclerView"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_marginBottom="2dp"
                android:clipToPadding="false"
                android:padding="@dimen/item_gallery_padding"
                app:layout_behavior="@string/appbar_scrolling_view_behavior" />

解决方法

首先,为什么你甚至需要另一个回收者视图？它通常通过可扩展的回收站视图来解决. Here is a nice tutorial.

其次,我看到这行cartAdapter.notifyItemRemoved(id);第二个回收商的通知在哪里？你有链接吗？你应该为它调用notifyDataSetChanged()！

哦,我的上帝有这么多的匿名课！我甚至无法理解你的代码中发生了什么！这简直难以理解.认真地摆脱那些东西.
