在带有角度的NS 5应用程序中，我正在使用特定于平台的css文件根据运行它的设备对应用程序进行样式设置。我有4个档案-
phone.android.css, phone.ios.css, tablet.android.css and tablet.ios.css存储在app文件夹中。
当我使用
tns run ios
我发现该应用程序运行并且样式正确应用。但是当我使用
tns run ios --bundle。
完全不应用css样式。
关于如何在特定平台的css文件中获取css样式以正确应用的任何建议。升级到NS 5和Nativescript-dev-webpack 0.17.0之前，即使使用bundle标志，所有样式都可以正常工作

答案 0 :(得分：0)
您应导入文件名中未指定平台的样式。
例如导入phone.css而不是phone.ios.css等。
在构建过程中，.ios / .android将自动添加，具体取决于您要构建的平台。
尽管您的帖子内容不清楚，但在您的评论中您提到了导入phone.ios.css，由于您的iOS应用正确加载了样式，因此问题得到了进一步的确认，而问题仅在于Android。
关于包-这是由于webpack最有可能在构建过程中使用，以上内容应为您解决。
P.S。 OP已经有将近一年的时间了，很可能找到了解决方案-但问题尚未得到解答。
OP，下次找到解决方案时，如果您自行发布解决方案:)
