我的 list_item 文件有一个 ImageView:

我该怎么办？！

如您在最后几行错误中所见：
Caused by: java.lang.UnsupportedOperationException: Can't convert to dimension: type=0x12
您似乎输入了一些您必须输入的维度。
并作为属性 android:baseline:
的文档
The offset of the baseline within this view. May be a dimension value,
which is a floating point number appended with a unit such as
"14.5sp". Available units are: px (pixels), dp (density-independent
pixels), sp (scaled pixels based on preferred font size), in (inches),
and mm (millimeters).
但是您使用了字符串作为基线值。
在 drawable 中复制图像文件时，您可以选择同时复制 drawable 和 drawable-24。确保将两者都复制，然后尝试 运行.
我的应用程序遇到了同样的问题，但最终我解决了它。
只需将您的图像文件放在 ic_launcher_background.xml 文件中而不是 ic_launcher_foreground.xml file.Hope 中，它会有所帮助。
