我的应用程序不会编译,当它抛出错误时,我的所有资源文件都消失了

Question

出于某种原因,当我尝试编译我的android工作室项目时,它一直说我的图像"默认"无效.它没有任何意义,因为在XML文件中,当您将视图更改为视图的设计模式时,它不会显示任何问题.编译完成后,Gradle会抛出一个问题而我所有的"R" 变成未找到的符号.也就是说,当我喜欢R.id.textview时,我所有的R都变红了,我无法改变它.

我的错误:

Error:error: invalid symbol: 'default'
Error:Execution failed for task ':app:processDebugResources'.

修复它,问题是我用图像命名为Default,这在android中是不允许的.这会搞砸我的Resources类.
