推荐答案

给你.

我设置了 4 个单选按钮供用户点击.

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

你一定是在radioGroup中定义的吧?

You must have defined them in radioGroup,right?

然后您可以在 RadioGroup 中进行迭代以将名称设置为 RadioButton或者您可以通过索引获取 RadioButton 并为其设置名称.

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));
        }
