我有RecyclerView。它有一个自定义布局，在自定义布局中是另一个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);
这是要移除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();
}
}

首先，为什么在另一个中甚至需要一个回收站视图？通常通过可扩展的回收站视图来解决。 Here is a nice tutorial.
其次，我看到这一行cartAdapter.notifyItemRemoved(id);哪里是第二个回收商的通知？你有链接吗？你应该为它呼叫notifyDataSetChanged()！
OH我的上帝有很多匿名的课程！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。

尝试这样：
@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);
holder.addon_recycleview.setHasFixedSize(true);
holder.addon_recycleview.setLayoutManager(new LinearLayoutManager(context, LinearLayoutManager.VERTICAL, false));
//Create a setter method in AddonRecycleviewAdapter adapter
holder.addon_recycleview.setLists(listsubdata.get(position), listsubprice.get(position), listsubAddon.get(position));
holder.addon_recycleview.setAdapter(recycleViewAdapter);
} catch (Exception e) {
e.printStackTrace();
}
}
在你的制定者中这样做：
//set list of items from ParentAdapter in your AddonRecycleviewAdapter adapter
public void setLists(List<T> l1,List<T> l2,List<T> l3) {
//Set You list as field variable here
this.l1 = l1;
this.l2 = l2;
this.l3 = l3;
this.notifyDataSetChanged();
}

最后，我从另一个方面得到了我的答案
我只需在synchronized(recyclerview){
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);
}
