Android Recyclerview items in ConstraintLayout doesn't display

Android Recyclerview items in ConstraintLayout doesn't display - android

I have a Constraint Layout which has RecyclerViews and some TextViews.All of the Recyclerview's visibility has been to set to 'gone' except last one.I have set that RecyclerView's width and height to match_constraint.The orientation of RecyclerView is Horizontal. The items are also have Constraint Layout as their parent. At runtime the items are not displayed.

}
}
HomeActivity.java:
recomm_recycler.setLayoutManager(new LinearLayoutManager(HomeActivity.this,LinearLayout.HORIZONTAL,false));
recomm_recycler.setAdapter(new HomeRecommendedProductsAdapter());

The textview with id "recomm_prdct_itemdesc" cannot have the height set to matchconstraint as it does not have a reference view to match its constraint like the width which can be matched to imageview with id "recomm_prdct_img". It should be set to wrapcontent.

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 not repeat recycle view inside nested layout?

I am trying to create a nested recycle view. So far i have a parent recycle view and under this i have a child recycle view. The problem that i am having is my child recycle view continues to be recycled with my parent recycle view. I do not want this i would like the child recycle view to only be recycled once. Does any one know how to go about fixing this. I understand this might sound a little confusing, but an example of what i want is instagram news feed. The top of the app have circle image views with your followers stories which can be swiped and the bottom have the news feed itself, in my case my app loads the user stories continuously under the news feed as i continue to scroll users stories are being continuously recycled under the news feed post.

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: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.

ViewFlipper outAnimation is not working

I want to continuously show different text on text view which animates from left to right, waits on the center of the screen for 3 sec and animates outside of the screen and replaced by a new text which animates from left to right
I have included a textview inside a viewflipper.

public void updateText(String[] strings) {

}
}
I guess the outanimation does not work as the textview length changes and I want to animate the constraint layout according to the textview height.
Not sure if this is the right reason.
The outAnimation of the view flipper does not work.

That's not how ViewFlipper works . the View flipper will only animate the view added to it .
Here's an example :
<ViewFlipper
android:id="#+id/viewFlipper"

The textview with id "recomm_prdct_itemdesc" cannot have the height set to matchconstraint as it does not have a reference view to match its constraint like the width which can be matched to imageview with id "recomm_prdct_img". It should be set to wrapcontent.
