I am working on a quiz app, and ran into a basic problem, I want to implement a checkbox where if both answers are correct, the score should get updated, I don't know where to place the code in java
Basically this is how the app should work, total questions 5, each carrying 2 marks, three mcq in which one is correct , 4th question both answers are correct , so we add checkbox ,each checkbox carries one mark,then the editText field so that user can add his own comments, after all the questions are answered by user , then and only then , after clicking on the submit button , Score should be presented to user! Thankyou
MainActivity.java file here
