                android:layout_gravity="fill|center" android:numColumns="auto_fit"
                android:layout_marginBottom="0dp" android:layout_width="wrap_content"
                android:layout_height="wrap_content"></GridView>
        </ScrollView>
    </RelativeLayout>

Answer 1

Correct your scroll view width and height as:

  <ScrollView android:layout_height="fill_parent"
            android:layout_width="fill_parent" android:id="@+id/scrollView1"
            android:layout_alignParentTop="true" android:layout_alignParentLeft="true">

Otherwise remove the ScrollView, just give GridView inside the RelativeLayout.

Answer 2

You should not put a gridview (as well as a listview) inside a scrollview. In your case it seems superfluous, because the gridview will provide the scrolling for itself.
