如果你分析下面的代码，你会看到有4个函数被多次调用（pushNextEntityUpdatedRows，pushNextUpdatedRow，pushNextEntityCreatedRows，pushNextCreatedRow），这不是一个BUG，这就是我如何设计我的代码来工作。你应该知道的是我有一个扩展 SQLiteOpenHelper 的类（DataAccess），我只将该类实例化一次。每次调用函数 pushNextEntityUpdatedRows 和 pushNextEntityCreatedRows 时，都会在我的DataAccess类实例中执行rawQuery。我从不关闭连接，我只关闭Cursor对象实例。我不知道造成这个 StackOverflowError 的原因是什么。我也不知道为什么它总是在145次调用之后发生。我该如何解决？谢谢你的到来。
堆栈跟踪告诉我：

答案 0 :(得分：2)
看起来你有一个循环或递归函数，它没有到达循环/函数的中断/结束。大多数情况下，当您使用if语句检查递归函数的结尾时，它实际上永远不会更改if语句的条件。在某些时候，你的计算机没有足够的“思考空间”进一步沿着兔子洞走下去。 （因为每次迭代占据整个空间的某个部分，以简单的方式说出来。显然，在145次迭代中，你已达到极限）
没有我们在这里无法帮助您的代码，如何添加示例代码？
