How can I check toggle buttons group?

Issue

I have a question related to material toggle buttons group. How can I check is any of toggle buttons in group selected? If any of buttons in group is selected then button 'Next' will be active, else button 'Next' will be inactive. Should I check each toggle button or there is a way to check group of toggle buttons?

Solution

You can use the method getCheckedButtonIds() to get all selected buttons.

To check if no buttons are selected you can use:

if (group.checkedButtonIds.isEmpty()){
    //...
}
