Question

I have three radiobuttons in a radiogroup. How can I tell Java to do a different thing depending on which button is selected? I have the group and all of the buttons declared:

final RadioGroup size = (RadioGroup)findViewById(R.id.RGSize);
        final RadioButton small = (RadioButton)findViewById(R.id.RBS);
        final RadioButton medium = (RadioButton)findViewById(R.id.RBM);
        final RadioButton large = (RadioButton)findViewById(R.id.RBL);

I know I would say something like this:

if (size.getCheckedRadioButtonId().equals(small){

} else{

}

But equals is not the correct syntax… How can I ask java which button is selected?

Answer 1

Try:

if (size.getCheckedRadioButtonId() == small.getId()){
 ....
}
else if(size.getCheckedRadioButtonId() == medium.getId()){
 ....
}
