移动到 Android Design Support v23 后，TabLayout 样式不能解析 @dimen/tab_max_width 的问题。

Question

在升级到Android Design Support v23.0.0之后，Android Studio无法构建一个之前使用Android Design Support v22.2.1正常构建的项目：

没有找到与给定名称匹配的资源（在“tabMaxWidth”处的值为“@dimen/tab_max_width”）。

发生了什么？

请确保将 compileSdkVersion 和 targetSdkVersion 设置为 23。 - Moinkhan

简而言之：你可能只需要在这些值前添加“design_”。

很高兴你问了，帅哥。v23.0.0已更改了一堆值，以下是v22.2.1的旧值：

在我的项目中使用“design_”前缀可以解决问题，但是我会收到以下警告信息： “@dimen/design_snackbar_extra_spacing_horizontal”资源在com.android.support：design中被标记为私有。不应引用私有资源；它们可能不在所有地方都存在，即使存在，也可能会在无声无息的情况下消失。”我猜解决这个问题的正确方法是将这些值复制到我的项目中，或者您还有其他解决方案吗？ - Tormod

是的，最好将它们复制进去。我遇到了这个问题，因为继承的代码，并没有研究这些值被引用的原理，看起来是不合理的。 - straya
