Java 如何修复API版本23的androidx中的FloatingActionButton充气错误？

我正在使用androidx创建一个基本目录应用程序。使用floatingAction按钮添加条目。 该应用程序在模拟器上运行得非常完美，但在我的手机上运行时，它会显示android.view.InflateException

错误-

我提到了很多解决方案，其中大部分都谈到了将android:backgroundTint更改为app:backgroundTint，正如您所看到的，我甚至没有使用它

已解决：只需将我的drawable ic_plus_white.xml从drawable-v-24文件夹移动到drawable文件夹。解决了这个问题

请确保您的应用程序或活动主题继承以下主题之一：

• 主题。材料组件
• Theme.MaterialComponents.NoActionBar
• 主题。材料组件。灯光
• Theme.MaterialComponents.Light.NoActionBar
• Theme.MaterialComponents.Light.DarkActionBar
• Theme.MaterialComponents.DayNight
• Theme.MaterialComponents.DayNight.NoActionBar
• Theme.MaterialComponents.DayNight.DarkActionBar

您的

可绘图/ic\u plus\u white

似乎不是有效的可绘图文件。请验证它的内容。

您遇到的问题位于启动活动XML的第26行。如果您能向我们展示该文件，我们可能会有所帮助。

我已经用我的

style.xml

更新了这个问题，我想我也已经更新了。那

drawable/ic\u plus\u white

呢？你也能分享一下吗？是的，好的，我会用它更新问题的？但我不知道这是否是一个错误的原因，因为它只是一个矢量资源。你能尝试添加一个不同的可绘制文件吗？如果可行的话，可能不是矢量可绘制文件？因为这个错误似乎与你的矢量绘制有关。谢谢你解决了这个问题！！我的drawable在drawable-v-24文件夹中，我将其移动到drawable文件夹中。工作起来很有魅力！感谢再次发布ActionButton xml是我的

main\u活动中第26行的xml代码。xml

您刚刚保存了我的一天：）
