How to allign 2x2 radio buttons into a group in android

Question

I'm new to android please let me know what I have made wrong, I have added a radio group and next added Gridlayout to align radio buttons in 2x2 form of matrix, it aligned good, but problem is that it is not deselecting previously selected options when I select any radio button. How can I achieve this ?

All radio buttons are getting selected. None of them are deselecting upon changing selection of radio button. Please suggest me any approach.

Thanks

RadioGroup is basically a LinearLayout within which you can align your RadioButtons. It's not like a generic layout that can store anything (GridLayout in your example) and it will handle any RadioButtons that you will put down in the hierarchy.

TLDR: RadioGroup lets you align your RadioButtons horizontally or vertically - it's a LinearLayout.

The thing you need to do is described in this question.
