我的 Android 应用程序运行良好，直到我在 XML 布局中使用滚动视图和子容器进行更改，线性布局下有许多控件。此特定布局不再运行，并导致应用程序停止工作。此外，IDE 有时会说标记不是 Android 资源中的有效元素。但是，当我更新 IDE 时，它得到了修复。但是现在，这种带有计算的特定布局不起作用。什么可能是这个问题的解决方案。我真的真的需要尽快完成这个应用程序。：| 只有这个布局不起作用......
我打算再次创建一个新项目，然后复制粘贴 XML 布局，这可以解决我的问题吗？除此之外，我之前此布局正常工作的所有备份文件都不再工作了。我很难对付这个。
我正在使用 INTELLIJ LEDA 社区版 IDE。任何帮助，将不胜感激！这是 XML：
