how to use one preference activity for multiple instances of the widgets?

I am working on an android home screen app widget.

i am trying to add preferences to the widget. i can put multiple widgets. but i want to configure it with preferences using shared preference created dynamically.

how can i load the preference from the resource file which fetches the value from the sharedpreference and also updates it?

any suggestion?

The key to the problem is to somehow use the setting saved by PreferenceActivity as reference and create your own setting. Below is what I used to achieve having multiple setting for multiple instances of app widget with single PreferenceActivity.

private void onExitPreferenceActivity(Context context, int appWidgetId) {
    // Load the user selected settings saved by PreferenceActivity
    final String SETTING_PREFIX = "COLOR";
    final SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(context);
    final String colorSetting = prefs.getString(SETTING_PREFIX, "");
    // Save the setting of the current widget with widget ID as the postfix
    final SharedPreferences.Editor prefEditor = prefs.edit();
    prefEditor.putString(SETTING_PREFIX + String.valueOf(appWidgetId), colorSetting);
    prefEditor.commit();
}

private void onLoadingWidgetSetting(Context context, int appWidgetId) {
    // Load the setting of a particular widget given a widget ID
    final String SETTING_PREFIX = "COLOR";
    final SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(context);
    final String colorSetting = prefs.getString(SETTING_PREFIX + String.valueOf(appWidgetId), "");
    // Use the loaded setting
    // ....
}
