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

i'm using recyclerview , i'm trying make 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; 

i fixed problem:

1- screen size (width).

2- make viewholder width same screen size.

below code if 1 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));
