Background Images in Android ListView are not Showing Up

Question

I have a custom ListView and adapter, and this is the code for my listview_item.xml:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" >

    <ImageView
        android:id="@+id/background"
        android:layout_width="fill_parent"
        android:layout_height="match_parent"
        android:scaleType="centerCrop" />

    <TextView
        android:id="@+id/title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_marginLeft="17.0dip"
        android:fontFamily="sans-serif-condensed"
        android:paddingTop="17.0dip"
        android:textColor="@color/white"
        android:textSize="24.0dip" />

    <TextView
        android:id="@+id/description"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_below="@id/title"
        android:layout_marginLeft="18.0dip"
        android:layout_marginTop="-3.0dip"
        android:fontFamily="sans-serif-condensed"
        android:textColor="#ffaaaaaa"
        android:textSize="13.0dip" />

    <Button
        android:id="@+id/btnRanks"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_centerVertical="true"
        android:focusable="false"
        android:focusableInTouchMode="false"
        android:text="Ranks" >
    </Button>

</RelativeLayout>

I want to set an image as the background of each list item, but when I call imageView.setImageDrawable(drawable);, I get a listview that looks like this: . You can see that the image fills the entire width of the listview, but not the height. How do I get the image to fill the listview's height as well?

By the way, this is the intended background image:

Answer 1

In your ImageView, instead of

android:layout_height="match_parent"

use

android:layout_height="wrap_content"

I'd also remove the attribute

android:scaleType="centerCrop"
