Changing XML R.layout on Run Time?

Hi Anddev Community,,

Is there a way to change the XML R.layout in Runtime?
The idea is if a user select a text in a list that text will be the name of the new pre-defined XML layout.

ie. R.layout.(//Text from List))

Thanks

Everything is possible...

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

 
private void setContentViewByName(String layoutName) {
 
        try {
 
                int layout = (Integer) R.layout.class.getDeclaredField(layoutName).get(null);
 
                setContentView(layout);
 
        }
 
        catch (Throwable t) {
 
                // Error getting specified layout
 
                // TODO Handle exception
 
        }
 
}
 
Parsed in 0.031 seconds,  using GeSHi 1.0.8.4

But, as you know what layouts are defined in your XML files there are more elegant (and a lot faster) ways to solve your problem. ;)

You can do it the "java" way, by coding the UI inside the .java file and not in the XML.
Then you could control how it would display under certain conditions/parameters.
