如何使用刷新按钮正确更新主屏幕小工具？(Android - Kotlin)

class MyWidgetProvider : AppWidgetProvider() {

    companion object {
        const val REFRESH_ACTION = "com.example.mywidget.REFRESH_ACTION"
    }

    override fun onUpdate(
        context: Context,
        appWidgetManager: AppWidgetManager,
        appWidgetIds: IntArray
    ) {
        // 更新小工具的视图
        // ...
    }

    override fun onReceive(context: Context, intent: Intent) {
        super.onReceive(context, intent)

        if (intent.action == REFRESH_ACTION) {
            // 处理刷新按钮点击事件
            // 更新小工具的数据和视图
            // ...
        }
    }
}

class MyWidgetProvider : AppWidgetProvider() {

    companion object {
        const val REFRESH_ACTION = "com.example.mywidget.REFRESH_ACTION"
    }

    override fun onUpdate(
        context: Context,
        appWidgetManager: AppWidgetManager,
        appWidgetIds: IntArray
    ) {
        // 更新小工具的视图
        // ...

        val refreshButtonIntent = Intent(context, MyWidgetProvider::class.java)
            .apply { action = REFRESH_ACTION }

        val refreshButtonPendingIntent = PendingIntent.getBroadcast(
            context,
            0,
            refreshButtonIntent,
            PendingIntent.FLAG_UPDATE_CURRENT
        )

        val views = RemoteViews(context.packageName, R.layout.my_widget_layout)
        views.setOnClickPendingIntent(R.id.refresh_button, refreshButtonPendingIntent)

        appWidgetManager.updateAppWidget(appWidgetIds, views)
    }

    override fun onReceive(context: Context, intent: Intent) {
        super.onReceive(context, intent)

        if (intent.action == REFRESH_ACTION) {
            // 处理刷新按钮点击事件
            // 更新小工具的数据和视图
            // ...
        }
    }
