ConstraintLayout, RadioGroup and two columns of RadioButton

阅读更多关于 ConstraintLayout, RadioGroup and two columns of RadioButton

问题 I have a ConstraintLayout as a root Layout and it's fine. However I now have a RadioGroup where I have to make two columns of RadioButtons within it. Since ConstraintLayout is about getting the rid of Nested Layouts, I thought it would be fine placing those RadioButtons in the RadioGroup and place them appropriately. Turns out having a ConstraintLayout as a Root layout, Containing the RadioGroup, doesn't seem to change anything. But maybe I'm wrong. How would you guys achieve having two rows

Android: custom layout for Radio Group

阅读更多关于 Android: custom layout for Radio Group

I'm trying to create a 2x2 array of radio buttons, but I don't know how to customize layout other than horizontal or vertical. Any ideas? I've only gotten A B C D and A B C D but I want to have A B C D EDIT: I resolved this issue. For anyone wondering, I set up two individual radio groups (i.e. one with AB and one with CD). I set onClickListener() for each RadioButton, and used clearCheck() on the second RadioGroup when a button in the first RadioGroup was clicked, and vice versa. You can easily do it by including two LinearLayout into your RadioGroup with a orientation="horizontal" .
