GridView auto fit images

Experiment with the GridView attributes, specifically android:numColumns="auto_fit" and android:stretchMode. The following works for me:

<GridView 
    android:id="@+id/myGrid"
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:padding="10dp"
    android:verticalSpacing="10dp"
    android:horizontalSpacing="10dp"
    android:numColumns="auto_fit"
    android:columnWidth="60dp"
    android:stretchMode="columnWidth"    
    android:gravity="center"
/>
