User RelativeLayout. Here is an example which places a TextView on Top of an ImageView and centers the text on the image.

<RelativeLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">
    <ImageView
        android:layout_width="wrap_content"
        android:id="@+id/MyImage"
        android:adjustViewBounds="true"
        android:layout_height="wrap_content"/>
    <TextView
        android:id="@+id/TextOnImage"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerVertical="true"
        android:layout_centerHorizontal="true"/>
</RelativeLayout>

A relativeLayout will solve your problem, because it allows you to define the position of every child element independantly from each other. Just use margin and paddings to adjust the exact layout you want.
