Cannot select previously selected RadioButton after reset

Question

I have a set of three RadioGroups each consisting of three RadioButtons. And a reset Button that sets all RadioButtons in all Groups to false (setChecked(false)).

Reset works fine (all RadioButtons are unchecked) except that after a reset, in each RadioGroup, only those two buttons can be checked that where not checked at the moment that the reset buton was clicked. Only after doing that all three buttons in the group can be checked again just like before.

I tried to add setFocusable(true) and setClickable(true) during reset but that doesn't make a difference. What else then focus or clickability may cause this and how to solve?

I target Android API 7.

Answer 1

found it here:

android radiobutton check after clearing check issue

Should have used radioGroup.clearCheck() instead of radioButton.setChecked(false) for each seperate Button.

Answer 2

RadioButton group enforces this rule: only one option selected at any time. You should't uncheck all or check more than one. CheckBox is designed for such use.
