Question

I have a couple of CheckBoxPreferences set up, my preference class extends PreferenceActivity and implements OnSharedPreferenceChangeListener
This is what I’m using to respond to people checking/unchecking the CheckBoxPreferences:

public void onSharedPreferenceChanged(SharedPreferences P, String K) {
    if (K.equals(CheckBoxPref_KEY_HERE)) {
        MyClass.BooleanVariable = P.getBoolean("CheckBoxPref_KEY_HERE", true);
    }
}

As far as I can tell, the onSharedPreferenceChanged method above is never even getting called?

Answer 1

checkBoxPreference = (CheckBoxPreference) this.findPreference("CheckBoxPref_KEY_HERE");

checkBoxPreference.setOnPreferenceChangeListener(new OnPreferenceChangeListener() {
    @Override
    public boolean onPreferenceChange(Preference preference, Object newValue) {
            // do your work here
            return true;
        }
    });
