Android Question No resource identifier found for attribute errors

[gadgetmonster]

Hi,

I have just tried to compile a project that I haven't opened in a few months and am getting the following errors:

Generating R file.                     
Error
res\layout\widget_actions_4x1_layout.xml:2: error: No resource identifier found for attribute 'layout_width' in package 'android'
res\layout\widget_actions_4x1_layout.xml:2: error: No resource identifier found for attribute 'layout_height' in package 'android'

Any ideas?

I guess that this layout file is read-only. What is the content of this file?
