好吧,我决定只使用pagertitlestrip。我假设我正在使用的支持库不包含 pagertabstrip。我不知道如何解决这个问题,因为我认为我已经正确更新了所有内容。编辑:这不再存在了吗?当我将 PagerTabStrip 更改为 PagerTitleStrip 时,一切正常,但我无法与预期的标题进行交互,因为这就是我想使用 PagerTabStrip 的原因。
我已经回到基础来找到问题的根源。我开始了一个导入 ABS 的新项目。我设置了一个非常简单的 pagerAdapter 和一个简单的片段。我使用了一本公共书籍中的一个例子,但我仍然遇到同样的错误。未找到类异常。找不到 PagerTabStrip。每次发布的堆栈都会出现相同的错误。如果我删除 PagerTabStrip,那么一切正常。

任何帮助都是极好的。我不确定在哪里可以解决这个问题。我觉得我错过了一些非常基本的东西,它阻止在支持库中找到 PagerTabStrip。
