RecyclerView item width layout_width=“match_parent” does not match parent

Question

I'm using RecyclerView and I'm trying to make the width item of RecyclerView match_parent since I'm using

LinearLayoutManager.HORIZONTAL

 <android.support.v7.widget.RecyclerView
            android:id="@+id/listOffersHits"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

custom_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:card_view="http://schemas.android.com/apk/res-auto"
    android:id="@+id/card_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="center"
    android:layout_weight="1"
    android:layout_margin="2dp"
    card_view:cardCornerRadius="2dp">
    <ImageView
        android:id="@+id/offerImage"
        android:layout_width="match_parent"
        android:layout_height="match_parent"

        android:background="@drawable/item_selector"
        android:scaleType="fitXY"
        android:src="@drawable/offer"
        />

</android.support.v7.widget.CardView>

LayoutManager

   LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getActivity(),LinearLayoutManager.HORIZONTAL, false);
    listOffersHits.setLayoutManager(linearLayoutManager);

ViewHolder

View view= LayoutInflater.from(parent.getContext())
                .inflate(R.layout.custom_layout, parent, false);
        ViewOffersHolder viewHolder=new ViewOffersHolder(view);
        return viewHolder;

Answer 1

Calling to GridLayoutManager instead of LinearLayoutManager and put one column is most simple

From your xml:

<androidx.recyclerview.widget.RecyclerView
        app:layoutManager="androidx.recyclerview.widget.GridLayoutManager"
        app:spanCount="1"
...

Or from Kotlin:

recyclerView.layoutManager = GridLayoutManager(this,1)

Or from Java:

recyclerView.setLayoutManager(new GridLayoutManager (this, 1);

Answer 2

I fixed the problem:

1- Get the screen size (width).

2- make the ViewHolder width same as screen size.

Below my code if any one need it.

WindowManager windowManager = (WindowManager)context.getSystemService(Context.WINDOW_SERVICE);
        int width = windowManager.getDefaultDisplay().getWidth();
        int height = windowManager.getDefaultDisplay().getHeight();
        view.setLayoutParams(new RecyclerView.LayoutParams(width, RecyclerView.LayoutParams.MATCH_PARENT));
