java - 如何找出这个ConcurrentModificationException崩溃的地方？

Question

我遇到了 ConcurrentModificationException 问题，并且无法弄清楚代码中发生这种情况的位置。调试给我的就是:

myApp [Android Application] 
DalvikVM[localhost:8631]    
    Thread [<1> main] (Suspended (exception ConcurrentModificationException))   
        ViewRoot.draw(boolean) line: 1631   
        ViewRoot.performTraversals() line: 1329 
        ViewRoot.handleMessage(Message) line: 1944  
        ViewRoot(Handler).dispatchMessage(Message) line: 99 
        Looper.loop() line: 126 
        ActivityThread.main(String[]) line: 3997    
        Method.invokeNative(Object, Object[], Class, Class[], Class, int, boolean) line: not available [native method]  
        Method.invoke(Object, Object...) line: 491  
        ZygoteInit$MethodAndArgsCaller.run() line: 841  
        ZygoteInit.main(String[]) line: 599 
        NativeStart.main(String[]) line: not available [native method]

ConcurrentModificationException 当您在迭代集合时修改集合时会发生。此时，仅搜索要更改集合的 foreach 循环可能会更容易。
