Android ImageView: Fit Width

I ended up using this code:

<ImageView 
                android:id="@+id/background"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:adjustViewBounds="true"
                android:scaleType="centerCrop"
                android:src="https://stackoverflow.com/questions/12059328/@drawable/name"
            />

Make sure you set the image using src instead of background.
