如何向小部件传递参数？

我正在开发一个小部件，我在这里有一个基本问题。

当用户单击小部件时。它将进入配置页面。我这里使用PendingIntent。

    Intent intent = new Intent(this, MyConfig.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);

    views.setOnClickPendingIntent(R.id.MyWidget, pendingIntent);

然后在配置页面上，我在这里有一些业务逻辑，我想将结果（对象）传递回更新小部件。

我使用下面的代码强制更新小部件，

AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(MyConfig.this);
int[] appWidgetIds = appWidgetManager.getAppWidgetIds(new ComponentName(MyConfig.this, MyActivity.class));
if (appWidgetIds.length > 0) {
    new MyActivity().onUpdate(MyConfig.this, appWidgetManager, appWidgetIds)
};

如何执行此操作？我应该将 Object 参数放在哪里，以便可以在 MyActivity 类上访问它？

谢谢

I'm developing a widget and I have basic question here.

When user click on the widget. It will go to config page. I use PendingIntent here.

    Intent intent = new Intent(this, MyConfig.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);

    views.setOnClickPendingIntent(R.id.MyWidget, pendingIntent);

On the config page then, I have some business logic here and I want to pass the result which is Object back to update widget.

I use codes below to force an update to widget

AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(MyConfig.this);
int[] appWidgetIds = appWidgetManager.getAppWidgetIds(new ComponentName(MyConfig.this, MyActivity.class));
if (appWidgetIds.length > 0) {
    new MyActivity().onUpdate(MyConfig.this, appWidgetManager, appWidgetIds)
};

How is the appropriate technique to do it?
Where I should put the Object parameter so I can access it on MyActivity class?

Thanks
