Android: View 层次结构中的重复 ID

Question

我有一个问题，来自市场的报告 - 应用程序严重崩溃，告诉我:

java.lang.RuntimeException: Unable to start activity ComponentInfo{com....android/com....android.activities....}: java.lang.IllegalArgumentException: Wrong state class, expecting View State but received class android.widget.ProgressBar$SavedState instead. This usually happens when two views of different type have the same id in the same hierarchy. This view's id is id/0x2. Make sure other views do not use the same id.

所以我知道这通常意味着它所说的 - 我在某个地方有重复 ID 的 View 。这很好，但让我担心的是，我认为重复的 id View 来 self 集成的某些 ad 网络。我试图在包含每个广告的 View 上使用 try/catch 来控制崩溃，但未能捕获它。

所以我的下一个想法是，广告 View 在这方面仍然有一些作用，但崩溃发生在另一个(我自己的) View 上，它具有相同的 ID。问题是，我不知道那个 View 是什么以及在哪里搜索它。你有什么想法可以是 id 0x2 的 View 吗？ (还有 0x3 - 也有很多关于该 ID 的报告)？您是否遇到过与广告网络相关的类似崩溃？

对此真的很沮丧。任何帮助表示赞赏!

谢谢，丹

从一个 fragment 切换到另一个包含相同 progressBar id 的 fragment 时遇到了这个问题。将 ID 更改为不同的 ID，问题就解决了。
