从单选按钮提交值
Posted

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了从单选按钮提交值相关的知识，希望对你有一定的参考价值。
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：

答案
你没有使用ids onRadioButtonClicked，answerA1和answerB1将onClick answerC1分配给第一个RadioGroup
在你的布局中，检查RadioButton的第一个RadioGroup。前三个答案在布局中缺少android:onClick="onRadioButtonClicked"线。相比
<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"
tools:targetApi="jelly_bean" />
同
<RadioButton
android:id="@+id/answerA2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="8dp"
android:fontFamily="monospace"
android:paddingLeft="8dp"
android:paddingRight="8dp"
android:onClick="onRadioButtonClicked"
android:text="@string/a2"
android:textSize="13sp"
tools:targetApi="jelly_bean" />
