安卓kotlin做一个意向。小部件配置类内的ACTION_SEND

我有以下配置类 MyWidgetConfigureActivity 对于小部件,但我需要确保如果 "text/plain" 类型 Intent.ACTION_SEND 如下所示,它可以做与我在上做的相同的事情 MyWidgetConfigureActivity 到 onClickListener 以添加小部件。

我也试着把同样的代码放在main中,它目前工作的地方,但作为appWidgetId,它给了我0。

你能帮我一把吗?

        val intent = intent
        val action = intent.action
        val type = intent.type

        if (Intent.ACTION_SEND == action && type != null) {
            if ("text/plain" == type) {
                val widgetText = intent.getStringExtra(Intent.EXTRA_TEXT)
                ...call function
            }
        }
