打开带有来自 attr 的颜色的新回收器视图时，应用程序崩溃

编程问答 2022-05-27

问题描述

我有 2 个活动 MainActivity 来展示一些书籍和 ViewMoreActivity 来展示更多书籍，MainActivity 完美打开而 ViewMoreActivity 打开时崩溃但是当我改变 {{ 1}} 为 textColor 形式 textView 到 android:textColor="?attr/text_color android:textColor="#000" 工作完美，那么我如何解决错误使用 ViewMoreActivity。

我遇到的错误

解决方法

如果 text_color 是您的 colors.xml 的一部分，请尝试使用 android:textColor = "@color/text_color" 而不是 android:textColor="?attr/text_color
