I am creating a MCQ app using recylerview where I have questions, 4 radio button and submit buttons. My program also has correct answer when submit click radio button and click submit button and if answer is correct I change the correct radio button background with green and red for wrong answer.
Now problem is that there are multiple questions with multiple submit buttons when I click first question correct radio button it changes its background red, same for all questions but except for last.
For last questions it gives correct background for correct and incorrect answer
Gif of my problem: https://ibb.co/LzQSVNz
In gif in first question ww2 is correct, but code changed its color to red and 2nd questions which is last is giving correct results.
