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();
}
}
