In gridview how to show only one row visible at a time

Question

I am a newbie in android. The grid view of my application has ,any rows and 1 columns. I want this to fill the screen ,irrespective of the screen size of the device. My need is i want to show just one row at a time in the user screen.

There are multiple items but only one item(row) should be visible and the next item should only be visible while scrolling.

now follows a code block: My Xml Code userviewmain_packages.xml

   <LinearLayout
    android:id="@+id/rlklj"
    android:layout_width="fill_parent"
   android:layout_height="fill_parent"
   android:layout_marginLeft="0dp"
   android:layout_marginRight="0dp"
   android:layout_marginBottom="0dp"
   android:layout_marginTop="0dp"
   android:layout_centerInParent="true"
  >  
<GridView 
android:id="@+id/gridview5"
android:layout_width="fill_parent"
android:layout_height="fill_parent"


  android:numColumns="1"

  android:verticalSpacing="0dp"

   android:scrollbars="none"
   android:gravity="center" />

    </LinearLayout>
  </RelativeLayout> 



userviewmain_packages_row.xml       

   //  This is the design part(layout) of gridview

     <LinearLayout              
 android:layout_width="fill_parent"
