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。

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