Android RecyclerView not showing the right xml -

i'm trying use recyclerview show horizontal list of contacts. spend hours find error , don't understand why keep happening. application tinder-like.

my row item :

<?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="80dp"     android:layout_height="80dp"     xmlns:tool="http://schemas.android.com/tools"     android:background="@color/white"     android:layout_margin="8dp">      <textview         android:id="@+id/tv_conversation_name"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:layout_gravity="center_horizontal"         android:layout_alignparentbottom="true"         android:textalignment="center"         android:textcolor="@color/black"         android:textsize="4pt"         tool:text="name name"/>      <imageview         android:id="@+id/iv_conversation_avatar"         android:layout_width="match_parent"         android:layout_height="match_parent"         android:scaletype="centercrop"         android:layout_margin="2dp"         android:src="@drawable/photo1"         android:layout_above="@id/tv_conversation_name"/> </relativelayout> 

this happen

i did layout 1 in other fragment

my adapter :

public class conversationadapter extends recyclerview.adapter<conversationadapter.conversationviewholder>{     private list<conversation> conversationlist = new arraylist<>();      public class conversationviewholder extends recyclerview.viewholder {         public textview title;         public imageview avatar;          conversationviewholder(view view) {             super(view);             title = (textview) view.findviewbyid(r.id.tv_conversation_name);             avatar = (imageview) view.findviewbyid(r.id.iv_conversation_avatar);         }     }      public conversationadapter(list<conversation> conversationlist) {         this.conversationlist = conversationlist;     }      @override     public conversationviewholder oncreateviewholder(viewgroup parent, int viewtype) {         view itemview = layoutinflater.from(parent.getcontext()).inflate(r.layout.item_conversation, parent, false);         return new conversationviewholder(itemview);     }      @override     public void onbindviewholder(conversationviewholder holder, int position) {         conversation conversation = conversationlist.get(position);         holder.title.settext(conversation.getname());          byte[] decodedbytearray = android.util.base64.decode(conversation.getimage(), base64.default);         holder.avatar.setimagebitmap(bitmapfactory.decodebytearray(decodedbytearray, 0, decodedbytearray.length));     }      @override     public int getitemcount() {         return conversationlist.size();     } } 

how configure recyclerview :

conversationadapter = new conversationadapter(conversationlist); recyclerview.layoutmanager mlayoutmanagerhorizontal = new linearlayoutmanager(getactivity().getapplicationcontext(),linearlayoutmanager.horizontal, false); rvconversation.setlayoutmanager(mlayoutmanagerhorizontal); rvconversation.setitemanimator(new defaultitemanimator()); rvconversation.setadapter(conversationadapter); 

it looks width , height of relativelayout in row item file 80dp, don't think want here. try setting these values "match_parent", this:

<?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" xmlns:tool="http://schemas.android.com/tools" android:background="@color/white" android:layout_margin="8dp"> 

or use "wrap_content", depending on trying achieve.
