How To Use Setonpreferencechangelistener For Quietlycoding Numberpicker?

I want to detect when the value from the NumberPicker is changed. I have this code on my PreferenceActivity: public class MainPrefs extends PreferenceActivity { @Override

Solution 2:

You have to call the listener yourself. Instead of notifyChanged(), try callChangeListener(val) as seen here:
