浮动操作按钮导致错误并导致应用程序崩溃

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。

这是我的完整错误日志：

Answer 1

确保您使用的是AppCompatActivity而不是Activity和AppCompat主题。

如果要为FAB使用任何属性（如backgroundTint或borderWidth ，请确保使用的是app namespace。

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

Answer 2

我面临同样的问题。 检查build.gradle应用程序中appcompat和design库的版本是否相同。 或者至少设计库的版本不比appcompat的版本旧。

例如：

 compile 'com.android.support:appcompat-v7:24.2.1' compile 'com.android.support:design:24.2.1' 

Answer 3

这个对我有用

 compile 'com.android.support:appcompat-v7:25.0.0' compile 'com.android.support:design:25.0.0'
