android - StackOverflowError，我不知道为什么

Question

我在 Android 4.0.3 上遇到过一次特定用户报告的以下崩溃。我在堆栈区中看不到对我的代码的引用，我想知道是否有人对可能导致此问题的原因有任何想法？

显然，不是最高优先级，因为它只被报告过一次，但我还是想了解一下。我无法在 4.0.2 上重现(我无法运行 4.0.3 模拟器)。

谢谢，

这是我主要 Activity 的 XML(使用 DrawerLayout 的那个)。 Lint 没有报告任何重要的事情，我在这里也没有看到明显的问题。

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

Answer 1

确定您有嵌套布局，所以您会收到此错误。 See this question .

此外还有layoutopt修复分层布局问题，但现在已替换为 lint在 SDK 工具修订版 16 之后。

所以使用lint

which can help you to easily identify and correct problems with the structural quality of your code as well as it checks your Android project source files for potential bugs and optimization improvements for correctness,
