Consider moving the layout for the line into a separate file:
<!-- horizontal_line.xml -->
<?xml version="1.0" encoding="utf-8"?>
<View
style="@style/HorizontalLine" />
... referencing a custom style definition:
<!-- styles.xml -->
<style name="HorizontalLine">
<item name="android:layout_width">fill_parent</item>
<item name="android:layout_height">@dimen/horizontal_line_height</item>
<item name="android:background">@color/horizontal_line_fill_color</item>
<item name="android:layout_marginTop">@dimen/large_spacer</item>
<item name="android:layout_marginBottom">@dimen/large_spacer</item>
</style>
... and then you can include
it in your layout:
<RelativeLayout
android:id="@+id/widget38"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_x="108px"
android:layout_y="87px" >
<include
android:id="@+id/horizontal_line"
layout="@layout/horizontal_line" />
<ImageView
android:id="@+id/widget39"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/horizontal_line"
android:layout_alignParentTop="true"
android:layout_alignParentRight="true" />
</RelativeLayout>
