RecyclerView catch catch onItemClickListener

I have 2 RecyclerViews that uses the same XML file to inflate views through the adapter.
One RecyclerView does catch clicks while the other doesn't.
The first RecyclerView is on another fragment and the code is similar to the second RecyclerView.
I have tried a lot of changes to the XML file(MaterialCardView) such as removing clickable attribute or changing the layout_weight to be 1 on the card but all of them didn't work.
Also, I can't understand why it would work only on 1 with the same settings on the other.
Here is the code for the second part which is not working:
Fragment - section of matter
list = view.findViewById(R.id.user_display_details_rv); //Getting the RecyclerView
list.setHasFixedSize(true);
int numOfColumns = 2;
list.setLayoutManager(new GridLayoutManager(getContext(), numOfColumns,GridLayoutManager.VERTICAL,false));
adapter = new UserDisplayDetailsAdapter(viewModel,getLayoutInflater());
list.setAdapter(adapter);
list.addItemDecoration(new RecyclerView.ItemDecoration() {
#Override
public void getItemOffsets(#NonNull Rect outRect, #NonNull View view, #NonNull RecyclerView parent, #NonNull RecyclerView.State state) {
outRect.set(5,20,5,20);
}
});
adapter.setOnItemClickListener((v,pos)->{
String pollId = Objects.requireNonNull(viewModel.getUserFilledPolls().get(pos).getPollId());
Navigation.findNavController(v).navigate(FragmentUserDisplayDetailsDirections.actionFragmentUserDisplayDetailsToFragmentOtherUserPoll(pollId,userId));
});
Adapter
public class UserDisplayDetailsAdapter extends RecyclerView.Adapter<UserDisplayDetailsHolder> {
UserDisplayDetailsViewModel viewModel;
LayoutInflater layoutInflater;
OnItemClickListener onItemClickListener;
public UserDisplayDetailsAdapter(UserDisplayDetailsViewModel viewModel, LayoutInflater layoutInflater) {
this.viewModel = viewModel;
this.layoutInflater = layoutInflater;
}
#NonNull
#Override
public UserDisplayDetailsHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
LayoutInflater inflater = (LayoutInflater) MyApplication.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.poll_list_square,parent,false);
return new UserDisplayDetailsHolder(view,onItemClickListener);
}
#Override
public void onBindViewHolder(#NonNull UserDisplayDetailsHolder holder, int position) {
Poll poll = Objects.requireNonNull(viewModel.getUserFilledPolls().get(position));
holder.bind(poll);
}
#Override
public int getItemCount() {
if(viewModel.getUserFilledPolls() == null){
return 0;
}
return viewModel.getUserFilledPolls().size();
}
public void setOnItemClickListener(OnItemClickListener listener){
this.onItemClickListener = listener;
}
}
Holder
public class UserDisplayDetailsHolder extends RecyclerView.ViewHolder {
MaterialTextView pollsName;
ShapeableImageView icon;
public UserDisplayDetailsHolder(#NonNull View itemView, OnItemClickListener onItemClickListener) {
super(itemView);
pollsName = itemView.findViewById(R.id.homescr_poll_pollName);
icon=itemView.findViewById(R.id.homescr_poll_icon);
itemView.setOnClickListener(v->{
int pos = getAdapterPosition();
onItemClickListener.onItemClick(v,pos);
});
}
public void bind(Poll poll) {
pollsName.setText(poll.getPollName());
}
}

How to align item vertically in a layout?

I try to dynamically populate a list and I have been following this question but for a reason my items aren't one under each other but one next to each others.
This is how I populate it using java:
public View onCreateView(#NonNull final LayoutInflater inflater,
final ViewGroup container, Bundle savedInstanceState) {
root = inflater.inflate(R.layout.fragment_detail_apero, container, false);
TextView name = (TextView)root.findViewById(R.id.name_apero);
name.setText(detailApero.getName());
TextView date = (TextView)root.findViewById(R.id.date_apero);
date.setText(detailApero.getDate());
LinearLayout ll = (LinearLayout)root.findViewById(R.id.vertical_layout_ingredient);
LinearLayout a = new LinearLayout(root.getContext());
a.setOrientation(LinearLayout.HORIZONTAL);
for(int i = 0; i < 20; i++)
{
Button b = new Button(root.getContext());
b.setText("Button "+i);
a.addView(b);
}
ll.addView(a);
and finally the xml structure:

I don't understand why they aren't coming one under each other, how can I do that ?

Recycleview custom layout constraint are changing for each inflated view causing problems

I have a recyclerview that inflates data fetched from json.
The issue I am facing are design issues - sometimes the text is aligned correctly and the image is shown and sometimes the text is too long, causing what I think is for the image not to be shown.
here is my XML:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.constraint.ConstraintLayout
android:layout_width="395dp"
android:layout_height="170dp"
android:layout_marginStart="8dp"
android:layout_marginTop="8dp"
android:layout_marginEnd="8dp"
android:background="#335634"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
<de.hdodenhof.circleimageview.CircleImageView
android:id="#+id/heroImage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="8dp"
android:src="#mipmap/ic_launcher"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="#+id/heroTitle"
android:layout_width="200dp"
android:layout_height="wrap_content"
android:layout_marginTop="16dp"
android:layout_marginEnd="16dp"
android:autoSizeMaxTextSize="25dp"
android:autoSizeMinTextSize="15dp"
android:text="Hero Title"
android:textSize="25dp"
android:textStyle="bold"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="#+id/heroDescription"
android:layout_width="200dp"
android:breakStrategy="simple"
android:layout_height="wrap_content"
android:layout_marginStart="36dp"
android:layout_marginTop="24dp"
android:layout_marginEnd="16dp"
android:autoSizeMaxTextSize="25dp"
android:autoSizeMinTextSize="15dp"
android:text="TextView"
android:textAlignment="center"
android:textSize="18dp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toEndOf="#+id/heroImage"
app:layout_constraintTop_toBottomOf="#+id/heroTitle" />
</android.support.constraint.ConstraintLayout>
</android.support.constraint.ConstraintLayout>
and here is my adapter:
public class HeroesAdapter extends RecyclerView.Adapter<HeroesAdapter.HeroesViewHolder> {
private List<Hero> heroList;
public HeroesAdapter(List<Hero> heroList) {
this.heroList = heroList;
}
#NonNull
#Override
public HeroesViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View rowView = LayoutInflater.from(parent.getContext()).inflate(R.layout.hero_cell, parent, false);
return new HeroesViewHolder(rowView);
}
#Override
public void onBindViewHolder(#NonNull HeroesViewHolder holder, int position) {
Hero currentHero = heroList.get(position);
String str = String.join(",", currentHero.abilities);
holder.heroTitle.setText(currentHero.title);
holder.heroAbilties.setText(str);
Picasso.get().load(currentHero.image).resize(500,500).into(holder.heroesImage);
}
#Override
public int getItemCount() {
return heroList.size();
}
public static class HeroesViewHolder extends RecyclerView.ViewHolder {
ImageView heroesImage;
TextView heroTitle;
TextView heroAbilties;
public HeroesViewHolder(#NonNull View itemView) {
super(itemView);
heroesImage = itemView.findViewById(R.id.heroImage);
heroTitle = itemView.findViewById(R.id.heroTitle);
heroAbilties = itemView.findViewById(R.id.heroDescription);
}
}
}
This is the result I am getting and this is the wanted result.
the issues I am facing are:
making each row have a clean design and act the same for all.
images are sometimes shown, sometimes not.
bottom view is "half in screen" and half out of screen.

By using LinearLayout you can design your hero_cell that will give you the desirable output. as I do it for now.
<?xml version="1.0" encoding="utf-8"?>

According to your expectation, you should use card-view and I've updated the layout. Please check

NestedScrollView not scrolling in recyclerView generated data

I'm using a NestedScrollView in a CardView that's generated in a RecyclerView. I can't get the scrolling to work - there seems to be sporadic moments when I can scroll through the list in the top item but no other scrolls seem to work. Cheers!
This is the layout of the cardView that's generated in the RecyclerView:

card_recyclerView.setLayoutManager(card_layoutManger);
card_adapter = new checkout_card_Adapter(cardPurchasesDataSet, card_totalPrice, card_extras, card_more, merchants);

}
}
}

As per your screen shot how do you expect it to scroll the inner view while it showing all the views? it will only scroll on small devices where your all textview won't be able to display. Can you please post a proper screenshot of this view from app.

ListView with databindings view tag isn't correct on view:null

I have a simple Adapter but always get the same error
view tag isn't correct on view:null
On my Activity I'm initializing the adapter as follows:
binding = DataBindingUtil.setContentView(this, R.layout.activity_main);
OptionsAdapter adapter = new OptionsAdapter(Option.defaultOptions());
binding.listView.setAdapter(adapter);
Here's my adapter
public class OptionsAdapter extends BaseAdapter {
private ObservableArrayList<Option> list;
public OptionsAdapter(ObservableArrayList<Option> list) {
this.list = list;
}
#Override
public int getCount() {
return list.size();
}
#Override
public Option getItem(int position) {
return list.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ItemBinding binding;
if (convertView == null) {
binding = DataBindingUtil.inflate(LayoutInflater.from(parent.getContext()), R.layout.item_layout, null, false);
convertView = binding.getRoot();
convertView.setTag(binding);
} else {
binding = (ItemBinding) convertView.getTag();
}
return convertView;
}
}
