Question

我有7个问题（7个RadioGroup），每个问题有3个答案（总共21个答案）。我的问题是我的观点错误地提交了。当我检查所有答案A时，提交的分数是18，而不是21。同样，当我检查所有答案B时，分数是12，答案C - 分数6.我不明白为什么，以及如何解决它

这是我的布局：

Answer 1

您尚未使用ids onRadioButtonClicked，answerA1和answerB1

将onClick answerC1分配给第一个RadioGroup

在您的布局中，检查第一个RadioButton的{{1}}。前三个答案在其布局中缺少行RadioGroup。比较

android:onClick="onRadioButtonClicked"

带

<RadioButton
            android:id="@+id/answerA1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginBottom="8dp"
            android:paddingLeft="8dp"
            android:paddingRight="8dp"
            android:fontFamily="monospace"
            android:text="@string/a1"
            android:textSize="13sp"
