采集接口有两种toArray方法。第一个对象[]toArray（）返回集合中的所有元素，并将它们存储在Object[]类型的数组中。第二个，T[]toArray（T[]a），如果集合元素足够大，则将其存储在方法的参数中，否则，它将通过在数组上的运行时反射来分配适当大小的数组。您的代码相当于以下代码： `

要修复它，只需使用邹祖建议的toArray（T[]a）版本的toArray。

。滑动（apoints.toArray（新点[apoint.size（）]），5）@ZouZou谢谢你……这很有效@Zouzu如果我不想用jsonString.length（）而是想用jsonObj传递一个数组的实际内容…这将在数组中获取数组…我该怎么做？我不确定我是否理解您想要实现的目标。你能说得更准确些吗？或者问一个新问题，这会更好：）@ZouZou语句“getUiDevice（）.swipe（（Point[]）apoints.toArray（），5）；”只获取字符串的总长度，但我希望传递每个坐标，以便所有坐标都通过swipe方法
