在android中使用picasso将多张图片同时显示到网格视图中

implementation 'com.squareup.picasso:picasso:2.71828'

<GridView
    android:id="@+id/gridView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:numColumns="3"
    android:verticalSpacing="4dp"
    android:horizontalSpacing="4dp"
    android:stretchMode="columnWidth"
    android:gravity="center"/>
