In fact, this XML file seems like itemrenderer In Flex or itemtemplate in Asp.net, the content is as follows:

<? XML version = "1.0" encoding = "UTF-8"?>
<Textview Android: text = "textview01" Android: Id = "@ + ID/textview01"
Android: layout_width = "fill_parent" Android: layout_height = "wrap_content"
