Supprimer la marge en fragment

Question

J'utilise un RecyclerView dans un fragment. Je veux que le fragment corresponde au parent en largeur et en hauteur. Mais ceci est ma sortie.

Il y a que l'espace étant laissé autour du fragment. Je veux éliminer cela. J'ai tout essayé, c'est-à-dire, fausse le troisième paramètre, en utilisant le conteneur parent, en changeant LayoutParams en match_parent mais rien n'a fonctionné.

Mon code: -

fragment.xml

<?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" 
android:id="@+id/RLGEVENT" 
android:background="@color/white"> 

<android.support.design.widget.FloatingActionButton 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_gravity="bottom" 
    android:clickable="true" 
    android:layout_marginLeft="16dp" 
    android:layout_marginBottom="16dp" 
    android:layout_marginRight="16dp" 
    android:layout_alignParentBottom="true" 
    android:layout_alignParentEnd="true" 
    android:src="@drawable/postbutton" 
    android:id="@+id/floatingButton" /> 

<android.support.v7.widget.RecyclerView 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:id="@+id/listView" 
    android:layout_alignParentTop="true" 
    android:layout_alignParentLeft="true" 
    android:layout_alignParentRight="true" 

    /> 

Fragment

@Override 
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { 


    view = inflater.inflate(R.layout.activity_gevent_main, container, false); 

    RelativeLayout rl = (RelativeLayout) view.findViewById(R.id.RLGEVENT); 
    rl.setLayoutParams(new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT)); 
    rl.invalidate(); 

    //code   

    return view; 
}
