Empty View on a dynamic RecyclerView

I am retrieving Data from MySQL Database in Android and I am using Recyclerview .I test php file and it is working fine but nothing shows in the activity. I checked every thing and it seems fine, I don't know what is the problem ?
Waiting Activity :

//adding our stringrequest to queue
Volley.newRequestQueue(this).add(stringRequest);
}
Product class :
public class Product {

this.Temp_dt = Temp_dt;
this.BusNumber = BusNumber ;
}
public int getWaitingTime() {

}
public int getBusNumber() {
return BusNumber ;
}
}

public class ProductsAdapter extends
RecyclerView.Adapter<ProductsAdapter.ProductViewHolder> {
private Context mCtx;
private List<Product> productList;
public ProductsAdapter(Context mCtx, List<Product> productList) {
this.mCtx = mCtx;
this.productList = productList;
}
#Override
public ProductViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
//inflating and returning our view holder
LayoutInflater inflater = LayoutInflater.from(mCtx);
View view = inflater.inflate(R.layout.list_layout, null);
return new ProductViewHolder(view);
}
#Override
public void onBindViewHolder(ProductViewHolder holder, int position) {
Product product = productList.get(position);
holder.textViewTime.setText(String.valueOf(product.getWaitingTime()));
holder.textViewBusNumber.setText(String.valueOf(product.getBusNumber()));
}
#Override
public int getItemCount() {
return productList.size();
}
class ProductViewHolder extends RecyclerView.ViewHolder {
TextView textViewTime;
TextView textViewBusNumber;
public ProductViewHolder(View itemView) {
super(itemView);
textViewTime = itemView.findViewById(R.id.textViewTime);
textViewBusNumber = itemView.findViewById(R.id.textViewBusNumber);
}
}
}
I expect to show temp_dt and waiting time from php file but the actual output is nothing just empty activity.

Android - Apply border dynamically to group of TextViews

I am wanting to display orders on a screen which I retrieve from a database. Each order has various items on it, and the screen will show the details of various orders and their items.
For example:
Order 1
Item1
Item2
Item3
Order2
Item4
Item5
,etc.
I am able to return this data with no issues, however I was wondering how to put a border around each order (as opposed to each item which is easy to do).
This is what the return looks like now (apologies as it does not show everything I wanted in this image). Basically I want a border around each specific order, so all the items in order 1 I want in a border, and then all the items in order 2 I want in a border.
The code is outline below and any help would be greatly appreciated:
This is the activity which displays the orders:
public class ChefScreen extends AppCompatActivity {
ListView listView;
List<ChefOrderList> listOrders;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_chef_screen);
listView = findViewById(R.id.list_chef_orders);
listOrders = new ArrayList<>();
displayOrders();
}
private void displayOrders(){
String url = "hidden";
StringRequest stringRequest = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
JSONObject obj = new JSONObject(response);
JSONArray array = obj.getJSONArray("orders");
for (int i = 0; i < array.length(); i++) {
final JSONObject orderObj = array.getJSONObject(i);
ChefOrderList c = new ChefOrderList(orderObj.getString("menu_item_name"), orderObj.getString("item_type"), orderObj.getString("order_date_time"),
orderObj.getInt("quantity_ordered"), orderObj.getInt("order_id"));
listOrders.add(c);
}
ChefOrderAdapter adapter = new ChefOrderAdapter(listOrders, getApplicationContext());
listView.setAdapter(adapter);
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(ChefScreen.this, "Oops! " +error.toString(), Toast.LENGTH_LONG).show();
}
}){
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<>();
params.put("menuid", "0");
return params;
}
};
MySingleton.getInstance(this).addToRequestQueue(stringRequest);
}
}
This is the layout for the chef screen:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_height="match_parent"
tools:context=".ChefScreen">
<ListView
android:id="#+id/list_chef_orders"
android:layout_width="330dp"
android:layout_height="430dp"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:layout_marginStart="15dp"
android:layout_marginTop="81dp"
tools:layout_editor_absoluteX="20dp"
tools:layout_editor_absoluteY="77dp" />
</RelativeLayout>
The adapter:
public class ChefOrderAdapter extends ArrayAdapter<ChefOrderList> {
private List<ChefOrderList> chefOrderList1;
private Context context;
public ChefOrderAdapter(List<ChefOrderList> M, Context C){
super(C, R.layout.listcheforders, M);
this.chefOrderList1 = M;
this.context = C;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater layoutInflater = LayoutInflater.from(context);
View view = layoutInflater.inflate(R.layout.listcheforders,null,true);
TextView orderNumber = view.findViewById(R.id.tvOrderNumber);
TextView itemType = view.findViewById(R.id.tvItemType);
TextView itemName = view.findViewById(R.id.tvItemName);
TextView orderQuantity = view.findViewById(R.id.tvItemQty);
TextView orderTime = view.findViewById(R.id.tvDateTime);
ChefOrderList chefOrderList = chefOrderList1.get(position);
itemName.setText(chefOrderList.getName());
orderQuantity.setText("Qty: " +chefOrderList.getQty());
if(position>0){
ChefOrderList prevChefOrderList = chefOrderList1.get(position-1);
if(chefOrderList.getOrder() != (prevChefOrderList.getOrder())){
orderNumber.setText("Order: " +chefOrderList.getOrder());
orderTime.setText(chefOrderList.getDate());
}
if(!chefOrderList.getType().equals(prevChefOrderList.getType())){
itemType.setText(chefOrderList.getType());
}
} else {
itemType.setText(chefOrderList.getType());
orderNumber.setText("Order: " +chefOrderList.getOrder());
orderTime.setText(chefOrderList.getDate());
}
return view;
}
}
The model class:
public ChefOrderList(String name, String type, String date, int qty, int order) {
Name = name;
Type = type;
Date = date;
Qty = qty;
Order = order;
}
public String getDate() {
return Date;
}
public String getName() {
return Name;
}
public String getType() {
return Type;
}
public int getQty() {
return Qty;
}
public int getOrder() {
return Order;
}
}
and finally the layout file for the list or orders:

How to update imageview from the parent recyclerview after click on nested recyclerview's imageview

Please check following screenshot, I want to update imageview from parent recyclerview when user click on imageview from nested recyclerview.
I have taken two individual adapters for for parent & nested recyclerview.I am not able to do the functionality for updating image, kindly help.
Parent Recyclerview Adapter:
public class RecyclerViewDataAdapter extends RecyclerView.Adapter<RecyclerViewDataAdapter.ItemRowHolder> {
private ArrayList<PLDModel> dataList;
private Context mContext;
public RecyclerViewDataAdapter(Context context, ArrayList<PLDModel> dataList) {
this.dataList = dataList;
this.mContext = context;
}
#Override
public ItemRowHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.item_card_view, null);
ItemRowHolder mh = new ItemRowHolder(v);
return mh;
}
#Override
public void onBindViewHolder(ItemRowHolder itemRowHolder, int i) {
final String itemTitle = dataList.get(i).getTitle();
final String itemDescription = dataList.get(i).getDescription();
ArrayList<SmallImages> singleSectionItems = dataList.get(i).getSmallImages();
itemRowHolder.itemTitle.setText(Html.fromHtml("<b>" + itemTitle + " </b> " + itemDescription));
SectionListDataAdapter itemListDataAdapter = new SectionListDataAdapter(mContext, singleSectionItems);
itemRowHolder.recyclerSmallImageList.setHasFixedSize(true);
itemRowHolder.recyclerSmallImageList.setLayoutManager(new LinearLayoutManager(mContext, LinearLayoutManager.HORIZONTAL, false));
itemRowHolder.recyclerSmallImageList.setAdapter(itemListDataAdapter);
}
#Override
public int getItemCount() {
return (null != dataList ? dataList.size() : 0);
}
public class ItemRowHolder extends RecyclerView.ViewHolder {
protected TextView itemTitle, expandImage;
protected ImageView bookmarkImage,largeImage;
protected RecyclerView recyclerSmallImageList;
protected Button btnMore;
public ItemRowHolder(View view) {
super(view);
this.itemTitle = (TextView) view.findViewById(R.id.title);
this.bookmarkImage = (ImageView) view.findViewById(R.id.bookmark);
this.largeImage = (ImageView) view.findViewById(R.id.large_image);
this.expandImage = (TextView) view.findViewById(R.id.expand);
this.recyclerSmallImageList = (RecyclerView) view.findViewById(R.id.recycler_small_image_list);
}
}
}
Nested Recyclerview Adapter:
public class SectionListDataAdapter extends RecyclerView.Adapter<SectionListDataAdapter.SingleItemRowHolder> {
private ArrayList<SmallImages> itemsList;
private Context mContext;
public SectionListDataAdapter(Context context, ArrayList<SmallImages> itemsList) {
this.itemsList = itemsList;
this.mContext = context;
}
#Override
public SingleItemRowHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.small_images_view, null);
SingleItemRowHolder mh = new SingleItemRowHolder(v);
return mh;
}
#Override
public void onBindViewHolder(SingleItemRowHolder holder, int i) {
SmallImages singleItem = itemsList.get(i);
}
#Override
public int getItemCount() {
return (null != itemsList ? itemsList.size() : 0);
}
public class SingleItemRowHolder extends RecyclerView.ViewHolder {
protected ImageView itemImage;
public SingleItemRowHolder(View view) {
super(view);
//this.tvTitle = (TextView) view.findViewById(R.id.tvTitle);
this.itemImage = (ImageView) view.findViewById(R.id.item_small_image);
view.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//Toast.makeText(v.getContext(), tvTitle.getText(), Toast.LENGTH_SHORT).show();
}
});
}
}
}

Using two Recyclerview will be hard to control rather than use a Single adapter and control everything from there.I have just worked on this type of thing that's why I am posting my code there may be some unwanted code which u may need.
/////Adapter class
public class AdapterTodayTrip extends RecyclerView.Adapter<AdapterTodayTrip.VHItem> {

Generally, the solution is to pass custom interface listener into the nested adapter and than the nested adapter will report any time one of his item clicked.
1.
You can create interface like:
public interface INestedClicked {
onNestedItemClicked(Drawable drawble)
}
2.
Pass in the constructor of SectionListDataAdapter a INestedClicked:
SectionListDataAdapter itemListDataAdapter = newSectionListDataAdapter(mContext, singleSectionItems, new INestedClicked() {
#Override
void onNestedItemClicked(Drawable drawble) {
// Do whatever you need after the click, you get the drawable here
}
});
In the constructor of SectionListDataAdapter save the instance of the listener as adapter parameter
private INestedClicked listener;
4.
When nested item clicked report the listener:
view.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(listener != null){
listener.onNestedItemClicked(imageView.getDrawable());
}
}

CardView in RecyclerView not inflating with all the values in list

I have a recyclerview that contains the cardview.The data is coming from server and is populated in a list. The Cardview adapter is not inflating the 2nd value from the list. The activity shows only one value on the screen:
This is the cardview screen

The listWorkers contains 2 workers. But only one is getting populated in the cardview. The worker is the normal bean class. I am not able to see the 2nd worker card on the screen. Please help me out and suggest the changes.

I noticed that the getView() is called more times than the count in the list (eg : if I have 2 messages getview() is called 4 to 5 times).
With the current code chat bubbles are always to the left irrespective of the chat status.
Firebase Data

I recommend to use two layouts - for your bubbles and your opponent. Use them in getView() method of your adapter. For list_item_message_own.xml use right allignment and for list_item_message_opponent.xml use left allignment, it depends on message status.
#Override
public View getView(Context context, Cursor cursor, ViewGroup parent) {
View view;
ViewHolder viewHolder = new ViewHolder();
MessageCache messageCache = ChatManager.getMessageCacheFromCursor(cursor);
boolean ownMessage = isOwnMessage(messageCache.getSenderId());
if (messageCache.getMessagesNotificationType() == null) {
if (ownMessage) {
view = layoutInflater.inflate(R.layout.list_item_message_own, null, true);
} else {
view = layoutInflater.inflate(R.layout.list_item_message_opponent, null, true);
}
viewHolder.timeAttachMessageTextView = (TextView) view.findViewById(R.id.time_attach_message_textview);
viewHolder.verticalProgressBar.setProgressDrawable(context.getResources().getDrawable(R.drawable.vertical_progressbar));
viewHolder.centeredProgressBar = (ProgressBar) view.findViewById(R.id.centered_progressbar);
} else {
view = layoutInflater.inflate(R.layout.list_item_notification_message, null, true);
viewHolder.messageTextView = (EmojiTextView) view.findViewById(R.id.message_textview);
viewHolder.timeTextMessageTextView = (TextView) view.findViewById(
R.id.time_text_message_textview);
}
view.setTag(viewHolder);
return view;
}
