在下面的代码中，单选按钮值没有保存到数据库中。当我调试时它显示为空。

是否有必要为单选按钮设置文本或使用文本视图名称？我们可以保存单选按钮的值。

这是我的布局设计：

像这样更改您的代码并查看调试到appointment_rb和customer_appointment值。

RadioButton appointment_rb = (RadioButton) findViewById(customer_appointment1.getCheckedRadioButtonId());
String customer_appointment = (String) appointment_rb.getText();

null 在哪里进行？

    <RadioButton
                  android:id="@+id/radioButton2"
                  android:layout_width="wrap_content"
                  android:layout_height="wrap_content" 
                  android:layout_marginLeft="40dp"/>

我没有看到这个按钮的文字。如果它将被选中，则文本将为空。

并且可能是用户没有选择任何按钮？

附言

next.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
        case R.id.next:

switch 没用，'v' 总是'next'

UPD

使用以下方法获取选中的单选按钮 ID，如果返回 -1，则表示用户没有选择任何单选按钮。

 radioGroup.getCheckedRadioButtonId(); // it will return unique ID of checked radio button or -1 on empty selection.

在此处查看文档 >> getCheckedRadioButtonID();

最后，这个字符串

setContentView(R.layout.feedback2);

为了什么？尝试评论它。
