android - 二进制 XML 文件行 #45 : Error inflating class ImageButton onload but only on some devices

Question

我收到这个错误:

Binary XML file line #45: Error inflating class ImageButton

我只是不明白为什么。它只发生在某些设备上，而不是全部。在同一个模拟器上它与 api 21 一起工作，但是当使用 api 19 时它就崩溃了。我试图找到解决方案，例如更新工具、删除库和类似的东西，但没有用。我该如何解决这个问题？

Answer 1

要清除 ImageButton 的来源问题:

FloatingActionButton 类扩展了 ImageButton 类。

---

错误如下:

资源不是 Drawable。

因此，在您的某个 FloatingActionButton 中的某处，您使用了一个包含错误或实际上不是图像的可绘制对象。

检查一下。
