Dynamic RadioGroup

Question

I have a RadioGroup that will have various numbers of children based on other factors. What I basically want to do is something like what you do with a RecyclerView, but I would be adding or removing RadioButtons from a RadioGroup instead of some other layout. Is there any good way to do this, or do I need to do it manually?

Hello,​

Welcome to our Microsoft Q&A platform!

but I would be adding or removing RadioButtons from a RadioGroup instead of some other layout. Is there any good way to do this, or do I need to do it manually?

I think need to do it manually with background code.

Firstly, we need to add the RadioGroup in the xml or background code. then add the RadioButtons at the runtime with background code(based on other factors). Because RadioGroup do not have adapter like RecyclerView. I add and remove RadioButton like following code.

   rg = FindViewById<RadioGroup>(Resource.Id.radioGroup1);  
                Button button1 = FindViewById<Button>(Resource.Id.button1);  
                rb = new RadioButton[5];  
                rg.Orientation = Orientation.Horizontal;//or RadioGroup.VERTICAL  
               for (int i = 0; i < 5; i++)  
               {  
                   rb[i] = new RadioButton(this);  
                   rg.AddView(rb[i]); //the RadioButtons are added to the radioGroup   
                   rb[i].Text = "Test";  
               }  
     
     
             //Or remove the RadioButtons   
     
             rg.RemoveView(rb[i]);//now the RadioButtons are in the RadioGroup
