I want to create a cart which has Nested array.
Like my parent array has items and child array has item's respective toppings but when i add toppings to my item array it automatically add same toppings to all index of items array. Here is my image:
Here i'm attaching my code below
Item_Array
private void addNewToppinDialoge(ProductsModel.Datum datum, int adapterPosition) {
ProductOrderModel.Datum productOrderModel = new ProductOrderModel.Datum();
productOrderModel.setCategoryID(datum.getProductID());
productOrderModel.setCategory(datum.getProductName());
int i = productActivity.productOrderModelArrayList.size();
int j = i + 1;
productOrderModel.setSrNO(String.valueOf(j));
productActivity.productOrderModelArrayList.add(productOrderModel);
productActivity.refreshOrderAdapter();
productActivity.changeTitleToolbar(datum.getProductName());
}
Toppings_array
private void addToppingToCart(ToppingsModel.Datum.LookupValue lookupValue, int adapterPosition) {
ProductOrderModel.Datum datum = new ProductOrderModel.Datum();
ProductOrderModel.Datum.SubCategory subCategory = new ProductOrderModel.Datum.SubCategory();
subCategory.setCategory(lookupValue.getLookupvalue());
int pos = productActivity.productOrderModelArrayList.size() - 1;
Log.e("POS", String.valueOf(ProductActivity.productOrderModelArrayList.size() - 1));
productActivity.productOrderModelArrayListSub.add(subCategory);
int subPos = productActivity.productOrderModelArrayListSub.size() - 1;
productActivity.productOrderModelArrayListSub.get(subPos).setCategory(lookupValue.getLookupvalue());
productActivity.productOrderModelArrayList.get(pos).setSubCategory(productActivity.productOrderModelArrayListSub);
productActivity.refreshOrderAdapter();
}
Adapter For Cart
public class MyOrderAdapter extends RecyclerView.Adapter<MyOrderAdapter.ViewHolder> {
public static ToppingsListAdapter toppingsListAdapter;
static Context mContext;
ArrayList<ProductOrderModel.Datum> orderModelArrayList;
public MyOrderAdapter(Context mContext, ArrayList<ProductOrderModel.Datum> orderModelArrayList) {
MyOrderAdapter.mContext = mContext;
this.orderModelArrayList = orderModelArrayList;
}

#Override

View mView = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.myorder_layout, viewGroup, false);
return new MyOrderAdapter.ViewHolder(mView);
}
#Override
public void onBindViewHolder(#NonNull MyOrderAdapter.ViewHolder holder, int i) {
holder.mTextOrderName.setText(orderModelArrayList.get(i).getCategory());
holder.mImageRemove.setOnClickListener(v -> removeItem(orderModelArrayList.get(i), holder.getAdapterPosition()));

} else {

holder.mRecyclerToppings.setAdapter(toppingsListAdapter);
}
}
protected void removeItem(ProductOrderModel.Datum productOrderModel, int adapterPosition) {
}
#Override
public int getItemCount() {
return orderModelArrayList.size();
}
public void refreshAdapter() {
toppingsListAdapter.notifyDataSetChanged();
}
public static class ViewHolder extends RecyclerView.ViewHolder {
public RecyclerView mRecyclerToppings;
private TextView mTextOrderName, mTextSerialNo;

public ViewHolder(#NonNull View itemView) {
super(itemView);

RecyclerView.LayoutManager manager = new LinearLayoutManager(mContext, LinearLayout.VERTICAL, false);
mRecyclerToppings.setLayoutManager(manager);
}
public int getAdapterPosition(ProductOrderModel.Datum.SubCategory remove) {
return 0;
}

I guess you need to header and footer of RecyclerView. Here is the code.
Try this one:
public class HeaderAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
private static final int TYPE_HEADER = 0;
private static final int TYPE_ITEM = 1;
String[] data;
public HeaderAdapter(String[] data) {
this.data = data;
}
#Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
if (viewType == TYPE_ITEM) {
//inflate your layout and pass it to view holder
return new VHItem(null);
} else if (viewType == TYPE_HEADER) {
//inflate your layout and pass it to view holder
return new VHHeader(null);
}
throw new RuntimeException("there is no type that matches the type " + viewType + " + make sure your using types correctly");
}
#Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
if (holder instanceof VHItem) {
String dataItem = getItem(position);
//cast holder to VHItem and set data
} else if (holder instanceof VHHeader) {
//cast holder to VHHeader and set data for header.
}
}
#Override
public int getItemCount() {
return data.length + 1;
}
#Override
public int getItemViewType(int position) {
if (isPositionHeader(position))
return TYPE_HEADER;
return TYPE_ITEM;
}
private boolean isPositionHeader(int position) {
return position == 0;
}
private String getItem(int position) {
return data[position - 1];
}
class VHItem extends RecyclerView.ViewHolder {
TextView title;
public VHItem(View itemView) {
super(itemView);
}
}
class VHHeader extends RecyclerView.ViewHolder {
Button button;
public VHHeader(View itemView) {
super(itemView);
}
}
}

Where does the code is wrong?
Your are type casting instance of super class to a reference of sub class which is causing this error.
Instead create something like this:-
public void onBindViewHolder(#NonNull BaseViewHolder holder, int position) {
if (holder instanceof DataQueHolder){
((DataQueHolder) holder).bind(dataList.get(position));
}else if (holder instanceof DataHolder){
((DataHolder) holder).bind(dataList.get(position));
}else if (holder instanceof ADSDataHolder) {
((ADSDataHolder) holder).bind(dataList.get(position));
} else if (holder instanceof PictureHolder) {
((PictureHolder) holder).bind(dataList.get(position));
}else if (holder instanceof QuestionHolder) {
((QuestionHolder) holder).bind(dataList.get(position));
}
}
Please remove this below line from DataListAdapter
recyclerView.setRecycledViewPool(pool);
It works for me..
I have two array list and want to set the adapter so that it looks like below screen one. But when I am setting adapter I am getting view like second screen. This is my code of Adapter:

this.mArticleList = mArticleList;
this.mQuizList = mQuizList;
}
#Override

}
else if(viewType == VIEW_TYPE_IMAGE){
itemView= LayoutInflater.from(parent.getContext()).inflate(R.layout.quiz,parent,false);
return new QuizViewHolder(itemView);
}
return null;
}
#Override

}
}
#Override

}

Log.e(TAG, "getItemViewType: " +position );
if(position < mArticleList.size()){
return VIEW_TYPE_MESSAGE;
}
if(position - mArticleList.size() < mQuizList.size()){
return VIEW_TYPE_IMAGE;
}
return -1;
}
public class ArticleViewHolder extends RecyclerView.ViewHolder {

public ArticleViewHolder(View itemView) {

}
}
}
To solve this error I also checked many solution on SO.
Ref: enter link description here
Below is screen one and screen two. Screen one that I need, Screen two that I am getting.
I have a little bit problem.In my activity there is two Adapter one is for color selection and another is for size selection. While i clicked one of the item of color then recently the available size adapter should be change but i got problem in size adapter. it changes only when i click the size item. I research and try to solve problem but it doesnt works for me.

At first both adapter will set data and after click color item the size adapter must be change but it only changes when i click any of the item. adapter.notifyDataSetChanged() doesnt work here for me.
Both Adapter set
When i click color item but doesnt change size adapter
when i click size item only change size adapter
Use Interface to bridge with two adapter and communicate with each other.
When scroll recyclerview some items mixes. After I add ads after every 15 items, holder get wrong data. Some items are vip items. I will change background color of these items. But when I scroll it dublicates mixes. How can I solve?
This is my adapter
private Context mCtx;
private List<Car> carList;
private RecyclerViewAnimator mAnimator;
private int AD_TYPE=1;
private int CONTENT_TYPE=2;
private int LIST_AD_DELTA=15;
public ProductAllCarAdapter(RecyclerView recyclerView,Context mCtx, List<Car> carList) {
this.mCtx = mCtx;
this.carList = carList;
mAnimator = new RecyclerViewAnimator(recyclerView);
}
#Override
public ProductAllCarAdapter.ProductViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
if(viewType == AD_TYPE){
View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.product_add_item, null);
ProductAllCarAdapter.ProductViewHolder vh = new ProductAllCarAdapter.ProductViewHolder(itemView);
mAnimator.onCreateViewHolder(itemView);
return vh;
} else {
View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.product_car_item, null);
ProductAllCarAdapter.ProductViewHolder vh = new ProductAllCarAdapter.ProductViewHolder(itemView);
mAnimator.onCreateViewHolder(itemView);
return vh;
}
}
#Override
public int getItemViewType(int position) {
if (position>0 && position % LIST_AD_DELTA == 0)
return AD_TYPE;
return CONTENT_TYPE;
}
#Override
public void onBindViewHolder(ProductAllCarAdapter.ProductViewHolder holder, int position) {
if (getItemViewType(position) == CONTENT_TYPE) {
final Car car = carList.get(holder.getAdapterPosition());
GlideApp.with(mCtx).load(car.getImg()).into(holder.imageView);
if (car.getVip() == 1) {
holder.relativeLayout.setBackgroundColor(ContextCompat.getColor(mCtx, R.color.colorVip));
holder.imageViewVIP.setVisibility(View.VISIBLE);
}
final String carid = String.valueOf(car.getCarid());
mAnimator.onBindViewHolder(holder.itemView, position);
} else {
holder.mView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Context mcontext = view.getContext();
Bundle bundle = ActivityOptionsCompat.makeCustomAnimation(mcontext, android.R.anim.fade_in, android.R.anim.fade_out).toBundle();
Intent intent = new Intent(mcontext, AdsItem.class);
mcontext.startActivity(intent, bundle);
}
});
mAnimator.onBindViewHolder(holder.itemView, position);
}
}
private int getRealPosition(int position) {
if (LIST_AD_DELTA == 0) {
return position;
} else {
return position - position / LIST_AD_DELTA;
}
}
#Override
public long getItemId(int position) { return position; }
#Override

int additionalContent = 0;
if (carList.size() > 0 && carList.size() > LIST_AD_DELTA) {

}
return carList.size() + additionalContent;
}
public static class ProductViewHolder extends RecyclerView.ViewHolder {
private View mView;
ImageView imageView, imageViewVIP;
RelativeLayout relativeLayout;
public ProductViewHolder(View itemView) {
super(itemView);
mView = itemView;
imageView = itemView.findViewById(R.id.imageView);
imageViewVIP = itemView.findViewById(R.id.imageViewVIP);
relativeLayout = itemView.findViewById(R.id.relativeLayoutpc);
}
public void setOnClickListener(View.OnClickListener listener) {
mView.setOnClickListener(listener);
}
}
I think problem onBindViewHolder function use wrong holder. ArrayList also return true value but on scroll it mixes.
You just have to add the corresponding else of the following if statement block.
if (car.getVip() == 1) {
holder.relativeLayout.setBackgroundColor(ContextCompat.getColor(mCtx, R.color.colorVip));
holder.imageViewVIP.setVisibility(View.VISIBLE);
} else {
holder.relativeLayout.setBackgroundColor(ContextCompat.getColor(mCtx, R.color.colorNormal));
holder.imageViewVIP.setVisibility(View.GONE);
}
This is inside your onBindViewHolder function where the view type is CONTENT_TYPE.
Hope that solves your problem.
I have a created this design. Which consists of list of list.
Now I wanted to add a view as "See All" in every section at the end of every recycler view. I wanted like this which is done by paytm.
Here is my code. I have two recyclerview one is vertical and another is horizontal. Here is my BaseRowAdapter which contains another recyclerview.
BaseRowAdapter.java
public class BaseRowAdapter extends RecyclerView.Adapter<BaseRowAdapter.ViewHolder> {
public ArrayList<MainType> types;
private Context context;
private LayoutInflater layoutInflater;
public BaseRowAdapter(ArrayList<MainType> types, Context context) {
this.types = types;
this.context = context;
this.layoutInflater = LayoutInflater.from(context);
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = layoutInflater.inflate(R.layout.vertical_scroll_single_entry, parent, false);
return new ViewHolder(view);
}
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
holder.recyclerView.setAdapter(new BaseRowItemAdapter(context, types.get(position).list));
holder.recyclerView.setLayoutManager(new LinearLayoutManager(context, LinearLayoutManager.HORIZONTAL, false));
holder.recyclerView.setHasFixedSize(true);
holder.tvHeading.setText(types.get(position).name);
}
#Override
public int getItemCount() {
return types.size();
}
public class ViewHolder extends RecyclerView.ViewHolder {
RecyclerView recyclerView;
TextView tvHeading;
public ViewHolder(View itemView) {
super(itemView);
recyclerView = (RecyclerView) itemView.findViewById(R.id.rvItems);
tvHeading = (TextView) itemView.findViewById(R.id.tvHeading);
}
}
}
And for Inner recyclerview I have to show see more layout at the end. I have done something like this. which result into crashing app.
BaseRowItemAdapter.java
public class BaseRowItemAdapter extends RecyclerView.Adapter<BaseRowItemAdapter.CustomViewHolder> {
private Context context;
private ArrayList<SubType> subTypes;
private LayoutInflater inflater;
public BaseRowItemAdapter(Context context, ArrayList<SubType> subTypes) {
this.context = context;
this.subTypes = subTypes;
this.inflater = LayoutInflater.from(context);
}
#Override
public int getItemViewType(int position) {
return (position == subTypes.size()) ? R.layout.see_more : R.layout.single_item_card;
}
#Override
public CustomViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view;
if (viewType == R.layout.single_item_card) {
view = inflater.inflate(R.layout.single_item_card, parent, false);
} else {
view = inflater.inflate(R.layout.see_more, parent, false);
}
return new CustomViewHolder(view);
}
#Override
public void onBindViewHolder(CustomViewHolder holder, int position) {
SubType subType = subTypes.get(position);
if (position != subTypes.size()) {
holder.tvProductName.setText(subType.name);
Picasso.with(context).load(subType.image).into(holder.ivProduct);
if (!subType.disc.equals("0")) {
holder.tvDiscountPercentage.setText(subType.disc + "%");
holder.tvActualAmount.setPaintFlags(holder.tvActualAmount.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);
int a = Integer.parseInt(subType.amount);
float b = Float.parseFloat(subType.disc) / 100;
holder.tvActualAmount.setText("₹ " + subType.amount);
int c = (int) (a * b);
holder.tvDiscountAmount.setText("₹ " + c);
} else {
holder.tvDiscountPercentage.setBackgroundColor(Color.parseColor("#ffffff"));
holder.tvActualAmount.setText("₹ " + subType.amount);
}
} else {
holder.seeMore.setText("See More >>");
}
}
#Override
public int getItemCount() {
return subTypes.size()+1;
}
public class CustomViewHolder extends RecyclerView.ViewHolder {
public ImageView ivProduct;
public TextView tvProductName, tvActualAmount, tvDiscountAmount, tvDiscountPercentage, seeMore;
public CustomViewHolder(View itemView) {
super(itemView);
tvProductName = (TextView) itemView.findViewById(R.id.tvProductName);
tvActualAmount = (TextView) itemView.findViewById(R.id.tvActualAmount);
tvDiscountAmount = (TextView) itemView.findViewById(R.id.tvDiscountAmount);
tvDiscountPercentage = (TextView) itemView.findViewById(R.id.tvDiscountPercentage);
ivProduct = (ImageView) itemView.findViewById(R.id.ivProduct);
seeMore = (TextView) itemView.findViewById(R.id.seeMore);
}
}
}
Here are my both model classes.
public class SubType {
public int id;
public String typeId;
public String name;
public String image;
public String unit;
public String amount;
public String disc;
}
public class MainType {
public int id;
public String name;
public ArrayList<SubType> list;
}
My few logcat details
java.lang.IndexOutOfBoundsException: Invalid index 2, size is 2
at java.util.ArrayList.throwIndexOutOfBoundsException(ArrayList.java:255)
at java.util.ArrayList.get(ArrayList.java:308)
at com.ashishkudale.linksolution.adapters.BaseRowItemAdapter.onBindViewHolder(BaseRowItemAdapter.java:54)
at com.ashishkudale.linksolution.adapters.BaseRowItemAdapter.onBindViewHolder(BaseRowItemAdapter.java:23)
It is crashing because of IndexOutOfBoundsException. I don't know how to solve this please help.
Change your onBindViewHolder
#Override
public void onBindViewHolder(CustomViewHolder holder, int position) {
if (position != subTypes.size()) {
SubType subType = subTypes.get(position);
holder.tvProductName.setText(subType.name);
Picasso.with(context).load(subType.image).into(holder.ivProduct);
if (!subType.disc.equals("0")) {
holder.tvDiscountPercentage.setText(subType.disc + "%");
holder.tvActualAmount.setPaintFlags(holder.tvActualAmount.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);
int a = Integer.parseInt(subType.amount);
float b = Float.parseFloat(subType.disc) / 100;
holder.tvActualAmount.setText("₹ " + subType.amount);
int c = (int) (a * b);
holder.tvDiscountAmount.setText("₹ " + c);
} else {
holder.tvDiscountPercentage.setBackgroundColor(Color.parseColor("#ffffff"));
holder.tvActualAmount.setText("₹ " + subType.amount);
}
} else {
holder.seeMore.setText("See More >>");
}
}
