在我的应用程序中，用户可以使用不同的帐户登录，而我想基于该帐户显示不同的数据，但是还存在一种状态，即用户尚未登录任何帐户。所以我想显示两种不同的布局。第一个包含帐户数据，第二个显示我的登录活动的按钮。我尝试切换按钮的可见性，但是当用户登录小部件时不会更新。
我的小部件的xml：
<?xml version="1.0" encoding="utf-8"?>
<appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android"
android:initialKeyguardLayout="@layout/updating_chart_widget_iot"
android:initialLayout="@layout/updating_chart_widget_iot"
android:minHeight="250dp"
android:minWidth="250dp"
android:previewImage="@drawable/chart_widget_preview"
android:resizeMode="vertical"
android:updatePeriodMillis="60000"
android:widgetCategory="home_screen">
</appwidget-provider>
这是我的窗口小部件提供程序的代码： 请告诉我我正在做哪一部分...

您可以强制主屏幕小部件的所有实例刷新如下：
{{1}}
我看不到登录和注销代码，但是可能只是在会话状态更改时调用updateWidgets（）的情况。
