GridView with incomplete row number does not scroll

Question

I have a problem with mine GridView, when it gets an incomplete line number of a line, it no longer scrolls. My elements are dynamic, which are set by the server, I have 3 columns, and if the number of elements is GridViewmore than enough to include scrolling, and if the row element is 3, it works fine. For example (9 points):

But if in the third line there are only 1 or 2 elements / s, it no longer scrolls (7 or 8 elements):

This caused me a headache more than the excitement of mine GridViewin the layout:

<GridView
    android:id="@+id/gridView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:background="@color/white"
    android:listSelector="@android:color/transparent"
    android:numColumns="3"
    android:stretchMode="columnWidth" >
</GridView>

My activity is nothing special, just the announcement and configuration of its adapter. Did I miss something? I tried to add verticalSpacingand paddingseparately, but nothing has changed.
