Title Body

I want to get value of a checkboxpreference. which method is suitable for listen to preference? And what's real difference between OnPreferenceChangeListener and OnSharedPreferenceChangeListener ?! UPDATE Why onSharedPreferenceChanged not called? public class Setting extends PreferenceActivity implements OnSharedPreferenceChangeListener // ,OnPreferenceChangeListener { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); addPreferencesFromResource(R.xml.preferences);// deprecated warning } @Override public void onSharedPreferenceChanged( SharedPreferences sharedPreferences, String key) {// DO Stuff } @Override protected void onResume() { super.onResume(); // getPreferenceScreen().getSharedPreferences().registerOnSharedPreferenceChangeListener(this); // PreferenceManager.getDefaultSharedPreferences(this).registerOnSharedPreferenceChangeListener(this); this.getSharedPreferences("myPrefDB", MODE_PRIVATE) .registerOnSharedPreferenceChangeListener(this); } @Override protected void onPause() { super.onPause(); // getPreferenceScreen().getSharedPreferences().unregisterOnSharedPreferenceChangeListener(this); // PreferenceManager.getDefaultSharedPreferences(this).unregisterOnSharedPreferenceChangeListener(this); this.getSharedPreferences("myPrefDB", MODE_PRIVATE) .unregisterOnSharedPreferenceChangeListener(this); } }
