Android 如何将温度值(从服务)检索到AppWidgetProvider
大家好,我是android小部件的新手,我搜索了一个示例来检索appwidget提供的温度(它在服务中),但我并没有弄清楚这一点。因此,我启动了一项服务来获取温度细节 这是我的服务(这里我得到了临时值)需要知道我想如何将此详细信息传递给AppWidgetProviderAndroid 如何将温度值(从服务)检索到AppWidgetProvider,android,android-widget,android-service,Android,Android Widget,Android Service,大家好,我是android小部件的新手,我搜索了一个示例来检索appwidget提供的温度(它在服务中),但我并没有弄清楚这一点。因此,我启动了一项服务来获取温度细节 这是我的服务(这里我得到了临时值)需要知道我想如何将此详细信息传递给AppWidgetProvider class MainService extends Service { private SharedPreferences sharedPref; private static final String Sync
