Answer 1

For the sample code, use this for a layout of 1 answer:

<FrameLayout
    android:id="@+id/answer_section"
    android:layout_width="100dp"
    android:layout_height="100dp">

    <ImageView
        android:id="@+id/answer_background"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@drawable/house_img"/>

    <ImageView
        android:id="@+id/answer_check"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@drawable/check_img"/>
</FrameLayout>

You use 2 different ImageView for 2 images so they can work separately, like doing animation, show/hide with conditions...
