我有一个RecyclerView。它具有自定义布局，并且在自定义布局内部是另一个RecyclerView。当我通知回收站查看某个项目已被删除时，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。如何在另一个回收视图适配器下回收视图适配器？
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);
这是用于RecyclerView刷卡删除的代码。在我的购物车适配器中，我采用了另一种适用的回收视图。任何想法如何通知适应如果有任何数据从回收视图中删除。???
我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();
}
}

你可以检查http://android-pratap.blogspot.in/2015/12/horizontal-recyclerview -in-vertical.html它会给你;很好的例子你在问什么。 –
是啊这是一些类似的东西，但没有任何代码如何通知SectionListDataAdapter中的任何更改 –
显示您的父级回收视图适配器代码..它需要在onBindViewHolder中设置ChildRecycleView而不是在ViewHolder类中... –
