RadioGroup | The missing iOS radio buttons group | Navigation library

I have programmatically added several RadioButtons to a pre-existing RadioGroup. The buttons themselves are there and are clickable, but their texts just won't appear. I have set their texts using the setText method, and by using Toast and RadioButton's getText method, I was able to confirm that all of the buttons do possess the texts they should have - they just don't display them.

I have made sure to set their alpha to 1, the text size to 20sp, their visibility to View.Visible, and I tried changing the text color and the background color several times to contrasting colors, but the text still didn't appear.

Can someone please help me figure out how to make the text appear?

The Java code:

I have a quiz page, where every time 3 questions will load one by one and on submit next 3 questions will load. On click of previous user can change his/her answer selected before clicking the submit button. But in the code the previous button is not functioning properly. After 5-6 click on previous button the user is redirected to next page. User can go on next page only after completing the quiz. but this is not happening. please help me out to figure out what is wrong in the code.

Here is a basic 9 radio buttons question in Shiny:

Is it possible to format these same 9 options into two labelled groups, with the second group occupying two columns?

I've written and optimized a Shiny app, and now I'm struggling with the IT section of the organization where I work to have it published on their servers. Currently, they are claiming that the app is not W3C compliant, which is true, according to the W3C validator.

The errors I'm trying to solve, with no success, are:

• Bad value “complementary” for attribute “role” on element “form”.

• The value of the “for” attribute of the “label” element must be the ID of a non-hidden form control.

Such errors can be seen also in very minimal shiny apps, like:

How can I use this to change the profile of a Turtle using Radio buttons? So when user selects a radio button different text should be displayed in the TextView. How can I set these objects? Currently there is no output displaying when the radio button is clicked. So I would like to get the details of the turtle from the object and set it.

I am using the following script (jsfiddle) to convert dropdown list to button selection. But it displays the text of the button from the value of the option.

Is there a way to change the text displayed for each button, without changing the value of the button? Like giving it an id (getElementById) or something? So the new buttons are like: Option 1, Option 2.. etc.

Current code:

I'm learning react and I am stuck. I am trying to share a form between Edit and Create components. I am having a really hard time figuring out what I am doing wrong to initialize the values of the checked property for the radio group. After the page loads I can toggle the radio buttons. Initially, however, neither is checked.

I'm starting to think I am setting up my checked property incorrectly on the form.

Edit component (forms parent component) :

I attempting to set a default checked box (value 100) if no button has been selected by the user/ or if the user does not explicitly select a checkbox. Please see my current implementation:
