Question

我将ActionBarSherlock集成到我的Android应用程序中。它主要运作良好，有一个严重的例外......

当专门在API级别10（对应于Android 2.3.3）上运行时，并且仅在该版本上运行时，当用户在两个特定活动之间导航时，会发生StackOverflowError（如下所示）。调用堆栈显示此错误完全在Android框架内发生，与我的自定义代码无关。

我知道它与ActionBarSherlock相关的唯一原因是，如果我将我的更改恢复到活动类，以便它们再次从标准Activity基类继承而不是SherlockActivity，则会发生错误，并恢复为非-Sherlock主题。

Answer 1

我很快就连续两次调用invalidateOptionsMenu()时遇到了类似的错误（在onResume中，然后在onPrepareOptionsMenu中）。

一旦我从onPrepareOptionsMenu中删除了invalidateOptionsMenu()来电，问题就消失了。也许这不是你情况下发生的事情，但我想我会把它作为一种可能的解决方案。

Answer 2

Android 2.x上的UI线程堆栈大小小于Android 4.x.这意味着旧版本更容易出现StackOverflowErrors。这解释了为什么您只能在旧版本中体验到这一点。

ABS的问题在于它会自动为您的布局添加一些嵌套视图（包含操作栏的主要布局）。您可以使用层次结构查看器来查看这些额外的视图。

如果您已经有一个包含许多嵌套视图的深层布局，那么添加ABS可能会添加额外的视图来填充您的堆栈。

我建议您简化布局并删除一些额外的视图。有关如何在Android开发人员博客中优化布局的一些提示（由Romain Guy提供）。如果你保存大约2-3个视图，它应该补偿ABS添加的内容，你应该没问题。
