为您的所有RadioGroup
rg1.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
// TODO Auto-generated method stub
int childCount=group.getChildCount();
for (int i=0;i<childCount;i++){
RadioButton r_btn = (RadioButton) group.getChildAt(i);
if (r_btn.getId() == checkedId) {
// do your stuf here
sum1=i+1; // since position is from 0.
}
}
}
});
rg2.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
// TODO Auto-generated method stub
int childCount=group.getChildCount();
for (int i=0;i<childCount;i++){
RadioButton r_btn = (RadioButton) group.getChildAt(i);
if (r_btn.getId() == checkedId) {
// do your stuf here
sum2=i+1; // since position is from 0.
}
}
}
});
hitung.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
total.setText(""+sum1+sum2);
}
});

您可以引用无线电组，并使用getCheckedRadioButtonId ()获取已选中的单选按钮ID。看看这里
RadioGroup radioGroup = findViewById(R.id.radio_group);
然后当你需要获得所选的无线电选项时。
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 ..您使用相同的ID（radioButton1）为您所有按钮的
