我的目标是创建一个自定义开关，其中包括选中状态和未选中状态之间的动画过渡。
我很容易地达到了默认状态，并且在这两种状态下我的开关都像预期的那样，并且在其状态改变时它也改变了外观。
当我附加动画选择器而不是常规选择器时，就会出现问题。
我遇到这样的错误：
android.view.InflateException：二进制XML文件行＃10：二进制XML 文件行＃10：错误夸大类android.widget.Switch
原因：android.content.res.Resources $ NotFoundException：文件 的res / drawable / switch_track_animation_unchecked_checked.xml来自 可绘制资源ID＃0x7f060072 在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_track_animated_selector.xml ID＃0x7f060070
我可以确保可以正确访问那些可绘制对象等。
我经历了无效的缓存，然后重新启动，清理构建，重新构建等，但是它不起作用。

我也检查了上面的方法，使用矢量可绘制而不是形状，结果也一样。 向量的例子

我希望此视图能够加载，并且不会在视图init上引发错误。
答案 0 :(得分：0)
您的问题是switch_track_animation_unchecked_checked.xml和switch_track_animation_checked_unchecked.xml是动画VectorDrawables的动画，并且这些动画使静态VectorDrawable处于动画状态。我想您是在为ShapeDrawable而不是VectorDrawable设置动画，这就是导致异常的原因。
您需要将switch_bckg_on.xml和switch_bckg_off.xml替换为<vector>...</vector>的实现，以在<animated-vector>...</animated-vector>块内对其进行动画处理。
或者，您可以用StateListAnimator代替AnimatedVectorDrawables，尽管我不确定这样做是否能够真正实现您想要的目标。

似乎您的 switch_track_animated_selector 没有一些没有任何 id 的默认状态。您可以尝试添加此状态。这在类似情况下帮助了我
