You need to get the radio button at that index, then get the value of the text of that button. Try this code below.
您需要获取该索引处的单选按钮，然后获取该按钮文本的值。试试下面的这段代码。
if(rg1.getCheckedRadioButtonId()!=-1){
int id= rg1.getCheckedRadioButtonId();
View radioButton = rg1.findViewById(id);
int radioId = radioGroup.indexOfChild(radioButton);
RadioButton btn = (RadioButton) rg1.getChildAt(radioId);
String selection = (String) btn.getText();
}

rb1=(RadioButton)findViewById(rg1.getCheckedRadioButtonId());
Now you can use rb1.getText()to get the text on the Radiobutton that is checked
