Answer 1

• Use android:src instead of android:background.
• Add android:adjustViewBounds="true"

Sets a drawable as the content of this ImageView.

Finally

<ImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@mipmap/background"
        android:scaleType="fitXY"
        android:adjustViewBounds="true" />
