Programatically changing the orientation of buttons within a RadioGroup

[Greum]

I have a constraint layout with a RadioGroup consisting of 3 RadioButtons which will usually be displayed horizontally. Under certain circumstances I want the buttons to be displayed vertically.

I have the following code:

RadioGroup rg = findViewById(R.id.radioGroup);
rg.setOrientation(ConstraintLayout.VERTICAL);

which gives Cannot resolve symbol on VERTICAL.

I'm not sure how to resolve this. Can anyone help, please?

VERTICAL isn't a property of ConstraintLayout - looks like it's a property of ConstraintLayout.LayoutParams https://developer.android.com/reference/android/support/constraint/ConstraintLayout.LayoutParams

Not something I've messed with much, but I would try using ConstraintLayout.LayoutParams.VERTICAL

Thanks. I thought it must be something like that but couldn't find an answer. However when I try that I get a message

Must be one of: LinearLayout.HORIZONTAL, LinearLayout.VERTICAL

so I'm guessing it can't be done using constraint layout

Sure but as I said

which will usually be displayed horizontally. Under certain circumstances I want the buttons to be displayed vertically

which is why I need to do it programatically
