设置gridview的属性中的子布局文件里面，加上android:gravity="center"

<RelativeLayout xmlns:android="

    <GridView
        android:id="@+id/grid_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_centerInParent="true"
        android:background="#f0f0f0"
        android:horizontalSpacing="4dp"
        android:numColumns="3"
        android:verticalSpacing="4dip">
 
    </GridView>
 
</RelativeLayout>
 
 
<?xml version="1.0" encoding="utf-8"?>
 
<RelativeLayout xmlns:android="

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#ffffff">
 
    <ImageView
