推荐答案

在这里你去。

我已经设置了4个单选按钮，用户点击。

I have set up 4 radio buttons for the user to click.

您必须radioGroup中定义了它们，对吧？

You must have defined them in radioGroup,right?

然后就可以在RadioGroup中重复，以名称设置为单选按钮
或者你可以通过索引和集名称获得单选它。

Then you can iterate in RadioGroup to set names to RadioButton or you can get RadioButton by index and set name to it.

RadioGroup radioGroup = (RadioGroup)findViewById(R.id.group);

    for (int i = 0; i < radioGroup .getChildCount(); i++) {
            ((RadioButton) radioGroup.getChildAt(i)).setText(String.valueOf(i));
        }
