Android studio 动画选择器在视图初始化时导致崩溃

我的目标是创建一个自定义开关，包括选中和未选中状态之间的动画转换

我很容易获得一个默认状态，我的开关在这两种状态下看起来都和预期的一样，当状态改变时，它会改变它的外观

当我附加动画选择器而不是常规选择器时，会出现问题

我遇到了这样一个错误：

android.view.InflateException:二进制XML文件行#10:二进制XML 文件行#10:膨胀类android.widget.Switch时出错

原因：android.content.res.Resources$NotFoundException:文件 res/drawable/switch\u track\u animation\u unchecked\u checked.xml from 可提取资源ID#0x7f060072 位于android.content.res.Resources.loadDrawableForCookie（Resources.java:2640）

原因：android.content.res.Resources$NotFoundException:文件 可绘制资源中的res/drawable/switch\u track\u animated\u selector.xml ID#0x7f060070

我可以保证我正确地使用了这些可抽取的东西等

我经历了无效缓存和重新启动，清理构建，重建等，但它不会工作

查看示例

<Switch
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:thumb="@drawable/switch_thumb_selector"
            android:track="@drawable/switch_track_animated_selector"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintBottom_toBottomOf="parent"
            android:checked="true"
            android:id="@+id/switch2"/>

我希望此视图能够加载，并且不会在视图初始化时抛出错误。

您的问题是

切换\u跟踪\u动画\u未选中\u已选中。xml

和

切换\u跟踪\u动画\u已选中\u未选中。xml

是动画的

矢量可绘制文件

，并且这些动画状态是静态的

矢量可绘制文件

状态。您正在尝试设置

ShapeDrawable

的动画，而不是

VectorDrawable

，我认为这就是导致异常的原因

---

您需要将

开关打开.xml

和

开关关闭.xml

替换为

…

实现，以便在

中为它们设置动画，虽然我不确定它是否真的能够实现您在此处尝试实现的目标。
您的切换轨道动画选择器似乎没有没有任何id的默认状态。您可以尝试添加此状态。这在类似的情况下帮助了我
嘿，谢谢你的回复。我在使用vector drawables时也遇到了同样的问题。我将更新我的问题，以便您可以看到这些向量。但这没用。
