How do i use default android resources in my layout xml?

[brnak]

There are loads of default resources in android. I want to use the \[code\]android.R.string.cancel\[/code\] and \[code\]android.R.string.ok\[/code\].I can do this in code easily enough\[code\]getString(android.R.string.cancel)\[/code\]but how do do it in the layout.xml\[code\]@string/cancel\[/code\]Tried a few things\[code\]@android.R.string/[email protected]/cancel\[/code\]but these do not work. I'm sure I have seen this on dev tutorials, but can't find it all now.
