Question

我在Fragment中使用RecyclerView。我希望片段在宽度和高度上匹配父级。但这是我的输出。

片段周围留有空间。我想消除它。我已经尝试了所有的东西，即使用父容器使第三个参数为false，将LayoutParams更改为match_parent但没有任何效果。

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;
}
