Can't set RecyclerView inside CardView?

I'm trying to put a RecyclerView inside a CardView and create items dynamically.
Obviously, in XML, RecyclerView is set inside CardView tag, but as you can see picture, RecyclerView item is created outside CardView.
(RecyclerView's items are the parts expressed as kg and set in the photo. And CardView is also an item of another RecyclerView.)
What's the problem?

Let me know if you need any other code.

Here is the Activity of your add/delete CardView:
//Item List if you want to add one or more Items
private List<MyItem> myItems = new ArrayList<>();
private Adapter smallCardAdapter;
private int size;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
RecyclerView recyclerView = findViewById(R.id.rv);
//Creates a new Object in the Adapter.class
smallCardAdapter = new Adapter();
recyclerView.setAdapter(smallCardAdapter);
CardView cardView = findViewById(R.id.cardView);
MaterialButton delete = findViewById(R.id.delete);
MaterialButton add = findViewById(R.id.add);
//Add onClickListener
add.setOnClickListener(v -> {
try {
size = myItems.size();
//if the value is 0, a new item is created
//if you want to delete the card after 0 than you have to change the value to 0
if(size == 0){
//Creates a new Object in the MyItem.class
myItems.add(new MyItem("Set","1kg"));
}else{
MyItem myItem = myItems.get(0);
//Replace kg with "" to make a Integer
String secondString = myItem.getSecondString().replace("kg","");
Integer value = Integer.valueOf(secondString);
value++;
myItem.setSecondString(value+"kg");
myItems.set(0,myItem);
}
updateAdapter();
}catch (Exception e){
Log.w("MainActivity","Add Button OnClickListener");
e.printStackTrace();
}
});
//Delete onClickListener
delete.setOnClickListener(v->{
try {
size = myItems.size();
//If the value is 0 then canceled to avoid errors
if(size == 0){
return;
}
MyItem myItem = myItems.get(0);
//Replace kg with "" to make a Integer
String secondString = myItem.getSecondString().replace("kg","");
Integer value = Integer.valueOf(secondString);
//if the value is one or lower
if(value <= 1){
//The card will deleted after updateAdapter();
myItems.clear();
}else{
value--;
myItem.setSecondString(value+"kg");
myItems.set(0,myItem);
}
updateAdapter();
}catch (Exception e){
Log.w("MainActivity","Delete Button OnClickListener");
e.printStackTrace();
}
});
}
private void updateAdapter(){
try {
smallCardAdapter.setItems(myItems);
}catch (Exception e){
Log.w("MainActivity","updateAdapter");
e.printStackTrace();
}
}
The custom Item called MyItem:
public class MyItem {
String firstString;
String secondString;
public MyItem(String firstString,String secondString){
this.firstString = firstString;
this.secondString = secondString;
}
public String getFirstString() {
return firstString;
}
public void setFirstString(String firstString) {
this.firstString = firstString;
}
public String getSecondString() {
return secondString;
}
public void setSecondString(String secondString) {
this.secondString = secondString;
}
}
The Adapter.java creates a smallCard:
public class Adapter extends RecyclerView.Adapter<Adapter.SmallCardHolder> {
private List<MyItem> items = new ArrayList<>();
#NonNull
#Override
public SmallCardHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
// I created a new smallcard for the CardView
View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.smallcard, parent, false);
SmallCardHolder smallCardHolder = new SmallCardHolder(itemView);
return smallCardHolder;
}
#Override
public void onBindViewHolder(#NonNull final SmallCardHolder holder, int position) {
//get the current item of the position
MyItem myItem = items.get(position);
String firstString = myItem.getFirstString();
String secondString = myItem.getSecondString();
holder.textViewSet.setText(firstString);
holder.textViewkg.setText(secondString);
}
#Override
public int getItemCount () {
return items.size();
}
public void setItems(List <MyItem> items) {
this.items = items;
notifyDataSetChanged();
}
class SmallCardHolder extends RecyclerView.ViewHolder {
//Here are the TextView's of the smallcard (smallcard.xml)
private TextView textViewSet;
private TextView textViewkg;
public SmallCardHolder(#NonNull View itemView) {
super(itemView);
textViewSet = itemView.findViewById(R.id.set);
textViewkg = itemView.findViewById(R.id.kg);
}
}
}
Create a new layout with name called smallcard.xml for the Adapter.java:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/set"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Set"
android:layout_centerVertical="true"
android:textSize="18sp"
android:layout_marginStart="5dp"
android:textColor="?attr/colorPrimary"
android:textStyle="bold"/>
<TextView
android:id="#+id/kg"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="kg"
android:layout_toRightOf="#id/set"
android:layout_marginLeft="55dp"
android:layout_centerVertical="true"
android:textColor="?attr/colorPrimary"
android:textSize="16sp"
android:layout_marginRight="10dp"
android:maxLines="1"/>
</RelativeLayout>
</RelativeLayout>
In your XML you have to give the CardView a name. I called it cardView. Here is the code android:id="#+id/cardView"
Result:
You will find more information as comments in the code.

Please Correct Me Where is doing Mistake
Thanks In Advance

You can achieve that requirement by using an expandable recycler view.
There are a lot of libraries you can use to achieve this.
You can use this library.
Or follow this post to achieve this on your own, you might need to make some changes to get the output as per your requirement.

Data Creating and occupying a blank space in layout, but cannot see it

The Data from the web service is received properly, I got it checked by printing all the value in Log, so obviously there is no error from my back-end service. The data is also occupying blank space as per the array size of my list in layout, but i cannot see the data, only white screen with the TextView. There are no errors in the LogCat. I don't know what i did wrong, little help would be appreciated. Thanks
This is my MainActivity which has AsyncTask to fetch the Data.

You probably should be getting your B_OfferProducts from list passed to adapter, that is from List offerproductlist, instead of creating an object every time.
Regardless of what you put in the constructor of B_OfferProducts class, your items will not be bind to the list, which is probably the reason why data is not loading correctly. These objects created will live only inside ViewHolder.
This means that you should replace
B_OfferProducts b_offerProducts = new B_OfferProducts();
in onBindViewHolder() with getting the object relevant to the current postion in the list, so like this:
B_OfferProducts b_offerProducts = offerproductlist.get(position)
I hope it helps. Cheers!

How to properly implement a nested recyclerview, child recyclerviews behaving oddly

I am developing a chat application. The chat messages consists of normal text messages and sometimes it can be a list of items in a recyclerview.
So I've implemented nested Recyclerview. So what happens is in the json response if the message is just a normal text is a textview will be displayed but the message contains a URL then the horizantal recyclerview is shown in place of textview.
The problem is if in the json reponse let's say there are 10 messages and in that 10, 4 of them are URL's so i should be seeing 6 normal texts and 4 Recyclerviews. But the nested recyclerview is behaving very oddly sometimes it doesn't even display, sometimes i can see 2 Recyclerviews and sometimes 4 of them but with the same URL (same list of items).
I don't what i am doing wrong. can someone take a look at the code and tell me what's wrong?

Recycler View not displaying text properly

I'm trying to implement recycler view in my android app. The data to be shown is got from a server, the data includes a timestamp that should also be displayed.
The code that is setting up the data with the recycler view is as follows:
try{
JSONArray jsonArray = new JSONArray(response);
if(jsonArray.length()!=0) {
TimeStamp = new String[jsonArray.length()];
for(int i=0;i<jsonArray.length();i++){
JSONObject jsonObject = jsonArray.getJSONObject(i);
TimeStamp[i] = jsonObject.getString("TimeStamp1");
int ij = TimeStamp[i].indexOf('T');
String s = TimeStamp[i].substring(0,ij-1);
String s2 = TimeStamp[i].substring(ij+1,TimeStamp[i].length()-1);
sb.append(s+"\n"+s2+"\n");
String mod = s+"\n"+s2+"\n";
dataset.add(new DataEntryModel(1,mod,10,1));
}
CustomAdapter myAdapter = new CustomAdapter(dataset);
recyclerView.setAdapter(myAdapter);
resultView.setText(sb.toString());
}else{
}
}catch (Exception e){
sb.append(e.toString());
resultView.setText(sb.toString());
}
As you can see from the screenshot for some reason the recycler view is not displaying the full string. I displayed the string in a textview above the button. That seems to be working fine. What is causing the recycler view to not render the items properly. If I try to render s2 first then the time until the the second : is displayed.

The adapter for the recycler view is
public class CustomAdapter extends RecyclerView.Adapter<CustomAdapter.MyViewHolder> {
ArrayList<DataEntryModel> dataSet;
CardView cards;
public class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
TextView UserName, TimeStamp;
public MyViewHolder(View itemView){
super(itemView);
this.UserName = (TextView)itemView.findViewById(R.id.userName);
TimeStamp = (TextView)itemView.findViewById(R.id.timestamp_of_user);
cards = (CardView)itemView.findViewById(R.id.card_view);
}
#Override
public void onClick(View view) {
}
}
public CustomAdapter(ArrayList<DataEntryModel> data){
dataSet = data;
}
#Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.card_fragment,parent,false);
MyViewHolder myViewHolder = new MyViewHolder(view);
return myViewHolder;
}
#Override
public void onBindViewHolder(MyViewHolder holder, int position) {
TextView userName = holder.UserName;
TextView TimeStamp = holder.TimeStamp;
userName.setText(SingletonDataClass.SharedPrefsUserNameForSession);
TimeStamp.setText(dataSet.get(position).getTimeStamp());
}
#Override
public int getItemCount() {
return dataSet.size();
}
}
What is the reason for this odd behavior of the recycler view? How can I fix this problem?
