Android小部件列表视图项目单击不工作（小部件通过服务更新）
拜托，我有点困在这里了。我正在使用一个用于间隔重复的AlarmManager，使用后台服务（而不是使用“onUpdate”方法）更新我的小部件。一切似乎都很正常，ListView填充数据，但由于某些原因，单击ListView上的项时没有启动PendingEvent上的活动集 更新： 我认为代码可以正常工作。在其他设备上进行了测试，效果良好（摩托罗拉和HTC）。但由于某些原因，它在我的三星Galaxy S5上不起作用 下面是代码 WidgetService.javaAndroid小部件列表视图项目单击不工作（小部件通过服务更新）,android,android-listview,android-pendingintent,android-appwidget,remoteview,Android,Android Listview,Android Pendingintent,Android Appwidget,Remoteview,拜托，我有点困在这里了。我正在使用一个用于间隔重复的AlarmManager，使用后台服务（而不是使用“onUpdate”方法）更新我的小部件。一切似乎都很正常，ListView填充数据，但由于某些原因，单击ListView上的项时没有启动PendingEvent上的活动集 更新： 我认为代码可以正常工作。在其他设备上进行了测试，效果良好（摩托罗拉和HTC）。但由于某些原因，它在我的三星Galaxy S5上不起作用 下面是代码 WidgetService.java public class Wi
