Answer 1

您可以引用单选按钮组并使用 getCheckedRadioButtonId () 获取选中的单选按钮 ID。看这里

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

然后当你需要获取选中的单选选项时。

int id = radioGroup.getCheckedRadioButtonId();
if (id == -1){
    //no item selected
}
else{
    if (id == R.id.radio_button1){
        //Do something with the button
    }
}

对于单选按钮，首先更改您的按钮 ID。您对所有按钮使用相同的 ID (radioButton1)
