I\'m new with android and java, so sorry if it\'s a too basic question but I\'ve tried to find a solution in the forums and google and I couldn\'t.
I have 24 buttons
The approach is misguided to begin with. If you want to associate a piece of arbitrary data (e. g. a string) with a view, that's what tag is for. The ID is numeric and it better stay that way.
EDIT much later: the OP's issue was a case of an XY problem. That said, the question title alone is a legitimate question in its own right.
