视图的高度与父级RelativeLayout的高度不同

Question

I'm trying to achieve the layout on the right of the image below. What I am currently getting is on the left.

Here is my layout:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    >

    <ImageView
        android:id="@+id/garment_grid_item_image"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" 
        android:background="@drawable/gridview_image_placeholder"
        android:contentDescription="@string/blank"
        android:scaleType="centerCrop"
        />

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/garment_grid_item_on_loan"
        android:src="@drawable/icon_borrowed"
        android:contentDescription="@string/blank"
        android:layout_alignParentTop="true"
        android:layout_alignParentRight="true"
        android:visibility="gone"
        />

    <View
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" 
        android:background="@drawable/item_border"
        />

</RelativeLayout>

@drawable/item_border (lime green is just to highlight the transparent areas):

The RelativeLayout is used as an item template for a GridView . garment_grid_item_image is being populated in code. garment_grid_item_on_loan is the purple triangle in the top right whose visibility is controlled in code.

The View at the bottom uses a 9 patch and it is the one I'm having trouble with. I want it to be as tall as the parent RelativeLayout but neither match_parent or fill_parent work. What can I do to get it to work?

I've just tried your layout with some similar images and it works fine when set as the root element in an Activity.

It could be to do with your RelativeLayout having wrap_content as its size, with the child Views not specifying a size to wrap. Try specifying a fixed size just to see if the problem goes away, then go from there.
