RecyclerView 在每个元素之间放置了一个可怕的空间

Question

嗨，你好吗？有人能帮我吗？

我想显示一个 RecyclerView 并让项目一个接一个地显示。

但我不明白为什么在每个元素之间以可怕的方式显示一个可怕的空间，就像你在这张图片中看到的那样。

我想显示没有空白的回收站视图的所有元素。

这是我使用的 xml

卡片视图

感谢任何建议或建议

Answer 1

我在 1 年前遇到了这个错误。 尝试将android:layout_height="match_parent" 更改为android:layout_height="wrap_content"

Answer 2

我遇到了类似的问题，RelativeLayout 作为recyclerview 中每一行的根元素。我建议将视图布局更改为RelativeLayout。

要解决此问题，请找到包含每一行的 XML 文件，并确保根元素的高度为 wrap_content NOT match_parent。
