Android – Stretch image in ImageView

I have an ImageView that has its height and width set to "fill_parent" with a Relative Layout that has the same values set.Set Image scaleType="fitXY"

Here The XML layout:

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


<ImageView
    android:id="@+id/imageView1"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:scaleType="fitXY"
    android:src="@drawable/background_image" />


</RelativeLayout>

Fits the width and height but the image is stretched.
