title: delete spacing between rows in Gridview
body: <p>I am using Gridview to put the images inside it, I split one image into small pieces of equal length and width e.g number of column=4 and number of rows=4
  then I put the pieces in ArrayList
  when I put the number of column equal count of pieces e.g 4 I get more space between the rows but when I put the number of column equal 2 I don't get more space and it is ok.
  what I should do to put the number of column as I split it e.g 4 in the example and not 2 !</p>
  
  <p>Note: the width of large image before the split equal width of screen.</p>
  
  <pre><code>this is my grid view 
  
  &lt;GridView 
            android:id="@+id/vincentgridview"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:horizontalSpacing="5dp" 
            android:verticalSpacing="5dp"
            android:adjustViewBounds="true"
  
            android:stretchMode="columnWidth"
            android:layout_marginTop="30dp"              &gt;
  </code></pre>
