It sounds like you're trying to dynamically inflate an xml layout and
run dynamic code.
XML Layout:
Android doesn't support the use of dynamic xml layouts:
“The view hierarchy inflation (and many other things that use XML
resources) relies on
the preprocessing performed by the resource compiler when
building the application.
They can not be used with plain XML files.
It would certainly be nice to be able to inflate from raw XML
files, but there is no
plan to do this any time soon due to the effort involved and that
it is questionable
whether the performance would be acceptable.”
Code:
Android is using compiled java. As it is not an interpreted language
you will not be able to use approaches available in other languages
e.g. Javascript's exec()
I've spent a fair bit of time looking at this problem myself and
basically the most viable solution is to come up with your own
simplified subset of layout commands and use these to dynamically add
views to a placeholder. As for the running of code again you need to
come up with a simplified set of changes you might want to make on the
fly e.g. what method to call onClick for button X.
I have considered writing a generic reusable solution to this very
problem but I think the subset of language components for both views
and code would be hard to define for unknown applications.
