注意:我的应用程序在旧设备 android 5 上运行良好。但是我在新版本中遇到了这个问题。现在我添加了登录和微调器的代码...... 我认为这可能是图像密度像素的问题。或者将东西放置在错误的位置。我需要专家的时间。请解决我的问题。

最佳答案
Caused by: android.content.res.Resources$NotFoundException:
Drawable android:color/highlighted_text_materialwith resource ID #0x1060118
这是一个NotFoundException，这意味着它在此路径中找不到任何此类颜色文件:
res/color/highlighted_text_material.xml
您可能应该更改此设置。
此外，我刚刚发现 Spinner 还存在另一个问题:
Caused by: android.view.InflateException: Binary XML file line #98: Binary XML file line #98: Error inflating class Spinner
我对这部分表示怀疑:
android:popupBackground="?android:attr/textColorHighlightInverse"
尝试将颜色更改为非私有(private)资源。
另一个问题是:
<item> tag requires a 'drawable' attribute or child tag defining a drawable
将其内容添加到您的drawable文件中:需要一个“drawable”属性或定义drawable的子标签
关于android - 二进制 XML 文件行 #19 : <item> tag requires a 'drawable' attribute or child tag defining a drawable，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/52580657/
