Oh, yeah I can do that. I can do manual check and target specifically radio
buttons I need with switch.
What I"m trying to do is target specific instances of RadioButton class in
this case based on my XML input I got from CMS and the choices users set in
it. For example what radio buttons will show and which ones wont'.
I"m trying to make 1 simply method that will look like this:
private void turnRadiosOnOff(int radioButtonID){
// and then I would target a specific radio button based on the ID
passed into this method like this:
RadioButton radioInstance = getRadioChild("_radio"+id);
}
So in my layout I would have all radio buttons defined but code would hide
them all with GONE and then I would just reveal the ones they selected in
the XML file by using this one simple method above by passing a simple ID.
Hope that make sense.
