删除片段中的边距

Question

我在片段中使用RecyclerView。我想要片段在宽度和高度上匹配父项。但这是我的输出。

周围有一个片段被留下了空间。我想消除这一点。我尝试了一切，即使用父容器将第三个参数设置为false，将LayoutParams更改为match_parent，但没有任何工作。

我的代码： -

fragment.xml之

<?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" 

    /> 

片段

@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; 
}

的填充应该在content_start
