I have a preference activity that has a language as ListPreference which displays the available language list. I can fill the list when onCreate is called, but I want to fill the list when the user clicks on it.

this is the java code : 

public class SettingsActivity extends PreferenceActivity implements OnPreferenceClickListener {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        try {
            addPreferencesFromResource(R.xml.settings);
        } catch (Exception e) {

        }

    }

    @Override
    public boolean onPreferenceClick(Preference preference) {

        if((preference instanceof ListPreference) && (preference.getKey().equals("language"))){
            ListPreference lp = (ListPreference)preference;
            CharSequence[] entries = { "English", "French" };
            CharSequence[] entryValues = {"1" , "2"};
            lp.setEntries(entries);
            lp.setDefaultValue("1");
            lp.setEntryValues(entryValues);
            return true;
        }
        return false;

    }
}

and this is the settings.xml (preference) :

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen
  xmlns:android="http://schemas.android.com/apk/res/android">
    <PreferenceCategory android:title="General Settings">
        <CheckBoxPreference android:key="enabled"  android:title="Application Status" android:summary="Enable or disable the application" />
         <ListPreference 
         android:key="language" 
         android:title="Language"
         android:dialogTitle="Application language" 
         android:summary="Select the Application language"
         />
    </PreferenceCategory>
</PreferenceScreen>

I searched but found no result! An exception occurs every time I click on that list.
