Android Gridview - Linear layout_height being ignored

Question

According to the accepted answer to this question GridView row height, if you...

"Set your LinearLayouts to be some specific height, and the rows will all be that height."

This does not appear to work in my case. I have a layout file for each row as so:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" 
    android:layout_width="wrap_content"
    android:layout_height="200dp"
    android:layout_gravity="center_horizontal">

    <ImageView 
        android:id="@+id/theimage"
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" 
        android:layout_gravity="center_horizontal"
        android:background="#ffff0000" />

    <TextView 
        android:id="@+id/thename"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" 
        android:layout_gravity="center_horizontal"
        android:gravity="center"
        style="?icontext" 
        android:background="#ff00ff00"/>

</LinearLayout>

And these are contained within a Gridview defined as so:

<GridView android:id="@+id/gridview" 
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" 
        android:numColumns="auto_fit" 
        android:columnWidth="100dp"
        android:background="@color/background" 
        android:verticalSpacing="1dp"
        android:horizontalSpacing="5dp" />

This ignores the 'android:layout_height="200dp"' and instead sets the row height to the cell's content.

What's worse is that when my TextView wraps onto a second line, that second line is obscured by the next row of cells.

What am I missing?

The problem is solved in the following question: Layout problem with button margin

android:layout_* attributes are LayoutParams and belong to the parent view. So they will be ignored if you don't specify any parent.
