I don't know if this is of any help, but since myself, I couldn't put
all linked RadioButtons inside a single RadioGroup element, but
instead, due to how the layout was implemeted, were separated here and
there, I wrote this class:
public class SeparatedRadioGroup
implements CompoundButton.OnCheckedChangeListener {
private final List<RadioButton> buttons = new
ArrayList<RadioButton>();
public void addButton(RadioButton button) {
if (buttons.isEmpty()) {
button.setChecked(true);
}
buttons.add(button);
button.setOnCheckedChangeListener(this);
}
public void onCheckedChanged(CompoundButton button, boolean state) {
if (!state) {
return;
}
for (RadioButton btn : buttons) {
if (btn != button) {
btn.setChecked(false);
}
}
}
}
So you can use it instead of using a RadioGroup, if nothing else
helps.
