【问题描述】：

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的工作，并且 错误消息说 - StringtoReal.invalidReal(string.boolean)line:63 在这里，我正在尝试添加 3 个文本视图的值，并在另一个文本视图中使用复选框上的勾号显示它们的总数

【问题讨论】：

请停止重复同样的问题。对于同一个问题，您已经有 2 个问题未解决。使用这些，并开始提供您被要求的信息。您正在发送垃圾邮件。我问过你 3 次 - 你试图添加的文本视图中的三个值是什么。为什么这么难理解？

【参考方案1】：

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

在设备上，您可以在某些手机上使用开发者选项来启用可见信号，表明您可能在前台工作过多。在我的 Galaxy Nexus 上，我可以导航到设置 > 开发人员选项 > 启用严格模式。选中该框会导致任何应用程序周围出现红色边框，当它导致出现您从 logcat 发布的消息时。

消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。唯一知道的方法是设备测试。
