Answer 1

Use the android:numColumns="2" in your GridView widget

<?xml version="1.0" encoding="utf-8"?>
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/grid"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:numColumns="2"
    android:verticalSpacing="10dp"
    android:horizontalSpacing="10dp"
    android:scrollbarStyle="outsideOverlay"
    android:verticalScrollbarPosition="right"
    android:scrollbars="vertical">
</GridView>

Answer 2

you can also set number of columns by programmatically in a GridView in following way:-

 gridview.setNumColumns(n);

where 'n' is the number of columns.
