Do the following:

@Override
public boolean onPreferenceChange(Preference preference, Object newValue) {
    if (newValue instanceof Boolean) {
        boolean isChecked = (boolean) newValue;
        // do whatever you want to do with this
    }
    return true;
}});

instanceof Boolean actually is not required, as newValue will be Boolean. But it is just to make sure that nothing bad can ever happen.

Use the newValue parameter that is passed to your changeListener.
