浮动操作按钮导致错误并导致应用程序崩溃 [英] Floating Action Button causing error and crashing application

问题描述

使用浮动操作按钮时，我的Android应用程序崩溃并抛出错误。当我删除它时，我的应用程序运行成功，但如果可以，我宁愿使用浮动操作按钮。

When using the floating action button, my Android application crashes and throws an error. When I remove it, my application runs successfully, but I'd rather use the floating action button if I can.

这是我的完整错误日志：

This is my complete error log:

推荐答案

确保你是USI ng AppCompatActivity 而不是活动和AppCompat主题。

Make sure you are using AppCompatActivity instead of Activity, and AppCompat theme.

<style name="Base.AppTheme" parent="Theme.AppCompat.Light.NoActionBar">

如果您使用任何属性，例如 backgroundTint 或者对于FAB， borderWidth ，请确保使用 app 命名空间。

If you are using any attributes like backgroundTint or borderWidth for the FAB, make sure you are using app namespace.

app:backgroundTint="@color/accent_color"
app:borderWidth="0dp"
