我有一个复杂的应用程序，当点击按钮触发两个视图通过FadeIn-和TranslateX-动画出现时出现此错误。视图已在之前加载并且也已插入到布局中（作为不可见）。在运行应用程序时，我点击按钮，出现错误。
这是堆栈跟踪：

关于这一点的奇怪之处在于，此错误的出现在很大程度上取决于构建的代码库。如果我注释掉一行（例如，只有一个视图被动画化，或方法调用其中一个视图），它就不会发生。例如。我不久前偶然发现了这个错误，改变了布局，它不再发生了，现在又回来了。此外，它似乎依赖于设备！？它出现在模拟器中，但现在它只出现在我的Samsung S5设备上（API 21，Forms 2.3.3-pre4）。但是如果发生错误，则每次都会发生相同的操作（首先点击相同的按钮）。
据我所知，SetTranslationZ负责在其父级中设置视图的深度索引。但是我并没有故意改变这一点。
有人能指出我可以尝试的其他方向吗？视图是否可以处理，同时仍然在父母的RelativeLayout中但是不可见？
