Radio Button listener on animation ends

I need to know when animation ends if user select a RadioButton from a Radiogroup.

My Case: I have a viewPager with questions when user answers at my question then move to the next position (question).

Sample code:

 @Override
public void onCheckedChanged(RadioGroup group, @IdRes int checkedId) {
    RadioButton checkedRadioButton = (RadioButton) group.findViewById(checkedId);
    viewPagerHelper.goToNext();
    Log.e("CardAdapter", "Text :" + checkedRadioButton.getText());
}

thanks
