问题描述

The method xxx of type new xxxx must override 的问题

The method isViewFromObject(View Object) of type new PagerAdapter(){} must override or implement a supertype method

网上说的方法： 一、

因为你的Compiler 是jdk1.5，只要把它改为 1.6
方法：
1. window ->preferences... -> java -> Compiler
2. Compiler compliance level : 6.0
二、 把项目的JRE变成6.0的
项目右键->build path->configure build path->java Compiler(左边那排中) ->在右边的Compiler compliance level 修改版本为6.0

试过了没有作用。

}

解决方案

竟然自己解决了，虽然不知道原因，哈哈哈！！谁能给解释下；
public boolean isViewFromObject(View view Object object)

{

        return view == object;      }              改成                 public boolean isViewFromObject(android.view.View view Object object)      {          return view == object;      }  

就可以了，我是先删除原来的override按提示自动添加未重写的方法，系统自动写出来的。

解决方案二：
The method of type must override a superclass method 相关问题
The method execute() of type XXXX must override or implement a supertype method
The method of type must override a superclass method 解决

解决方案三：
制定是jdk版本的问题，要不就是工具的问题，实在不行就把注解删了呗。

解决方案四：
奇怪的是其他几个函数也是override，怎么就不报错，就isViewFromObject这个函数报错，删掉不行，父类的抽象函数必须要重写，删掉一样会报错的。
