RadioGroup doesn't transfer data or open the next Activity

22 views Asked by At

I'm trying to make a questionaire app on Android Studio but the app closes whenever I press the proceed button on the first question page.

I used a RadioGroup for each question and each RadioButton contains a number that will be transferred to the next Activity. At the end of the questionaire, it will show a result based on the number that was calculated from the answers.

This is what I did but I feel like I'm missing something. Can anyone help me or even simplified the code? Thank you!
