Logcat说 - 应用程序可能在其主线程上做了太多工作并且错误消息说 - StringtoReal.invalidReal(string.boolean)行:63

Question

每当我在模拟器中运行我的应用程序时,Logcat说 - 应用程序可能在其主线程上做了太多工作并且错误消息说 - StringtoReal.invalidReal(string.boolean)行:63这里,我试图添加3个textviews的值并使用checbox上的tick显示他们在另一个textview中的总数

我会忽略这一点.您看到的消息在手机上很重要,但在模拟器中却不重要.模拟器非常慢.您所做的一切都不是资源,因此您的应用程序应该在设备上名义上执行.

在设备上,您可以在某些手机上使用开发人员选项来启用可见信号,使您可能在前台进行过多工作.在我的Galaxy Nexus上,我可以导航到设置>开发者选项>启用严格模式.检查该框会导致红色边框在任何应用程序周围闪烁,因为它会导致出现类似于从logcat发布的消息.

删除警告的解决方案是线程,但我觉得您可能正在努力解决非问题.唯一可以知道的是设备测试.
