android - AppBarLayout.onCreateDrawableState 空指针异常 : Attempt to get length of null array

我们在三星 6.0.1 设备上遇到了太多此类崩溃。我们甚至得到了具有相同操作系统版本的相同设备，但仍然无法自行复制。我们收到其他膨胀异常，可能它们是相关的。

这个问题有解决方法吗？

支持库版本 - 24.2.1

这是完整的堆栈跟踪:

最佳答案

当 AppBarLayout 试图初始化它的滚动条时抛出这个异常 - 很可能你的 Activity 样式设置了默认的滚动条样式并且 AppBarLayout 继承了它。

最简单的解决方案是确保 AppBarLayout 永远不使用滚动条，只需按照以下步骤操作:

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:scrollbars="none">

    <!--YOUR LAYOUT-->

</android.support.design.widget.AppBarLayout>

我很确定我没有在 Android 项目中看到针对此问题的正确错误报告，所以我想是时候报告了。

编辑

我已经创建了示例应用程序来重现此问题 - 您可以找到它 here .当您在具有 API22 的设备上启动应用 issue-254934 - AppBarLayout 配置均有效，对于 API23 及更高版本，其中一个会导致与您在此处报告的完全相同的异常。

编辑

Issue-254923已经修复，错误修复将在未来的版本中发布
