我尝试使用此link
解决我的问题更新 - 我发现挂起的意图的设置者有问题 - 每次我点击imageview-意图发送最后定义的小部件的极端细节 - 意味着在预先添加的小部件上定义的其他待处理意图由较新的小部件重新运行
我有一个应用程序小部件，显示用户选择的图片。（许多小部件 - 许多图片） 我的问题是：无论我在屏幕上显示哪个小部件 - 只有最后添加的小部件会更新： 这是我的代码

问题不在于您的configActivity，问题出在您的widgetProvider中。我遇到了与您相同的问题，但使用您指定的link解决了问题。您需要在 buildRemoteView 中的 configIntent 上设置“黑客”意图。

当我在2.2或2.3版本的模拟器上测试我的应用程序时，我遇到了同样的问题。在真实设备上，一切都应该正常。而且，在我的情况下，模拟器4.0正常工作。在任何情况下，我建议您在真实设备上进行测试。
