按上面这个提示去查询你的错误 --------------------编程问答-------------------- 空指针异常,可能你的引用的对象是NULL,而你却NULL.方法名了,具易做图置查找按楼上两位说的就可 --------------------编程问答-------------------- Failed to execute runnable (java.lang.NullPointerException)关键是这句， --------------------编程问答-------------------- 这是Eclipse内部包的错误，楼主可以找到相应的包进行替换。 --------------------编程问答-------------------- 哦 记得了 有替换了一个jar包 。谢谢 --------------------编程问答--------------------
替换的什么包啊？ --------------------编程问答--------------------
