这是我的代码，有两个错误啊

第一个那个上面告诉我说是

Multiple markers at this line

- The method setOnCheckedChangeListener(CompoundButton.OnCheckedChangeListener) in the 

type CompoundButton is not applicable for the arguments (new RadioGroup.OnCheckedChangeListener(){})

- The type new RadioGroup.OnCheckedChangeListener(){} must implement the inherited abstract 

method RadioGroup.OnCheckedChangeListener.onCheckedChanged(RadioGroup, int)

第二个是

The method onCheckedChanged(CompoundButton, boolean) of type new RadioGroup.OnCheckedChangeListener()

 {} must override or implement a supertype method

我也倒了包了，我是看着老师的代码写的，这个怎么改，求大神！！
