Drawing Line: shape vs View?

[Kelly Powell]

In Android, one can draw a line using shape or View. Assuming that I am using the code below, which is better in terms of efficiency, etc if I am planning to reuse the line in other Activities? Why?

Using shape: (Will then be use as a background for a certain text.)
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"> <item> <shape> <solid android:color="#000000" /> </shape> </item> <item android:top="1dip"> <shape> <solid android:color="#FFFFFF" /> </shape> </item> </layer-list>
Using View: (Will then be placed on top of a certain text.)
<View android:layout_width="match_parent" android:layout_height="1dip" android:background="#000000"/>
