可能的重复：
来自匿名内部类的外部类的关键字？< /a>

我需要访问匿名内部类中外部类的实例并执行类似的操作。谁能澄清这是否正确？

public class ClassA{

ClassA refernceOfClassA = this;  

    public void m(){
       //Do something
    }
    Runnable target = new Runnable(){
       public void run(){
           //Code goes here using the refernceOfClassA
           refernceOfClassA.m();      
       }
    };
}

keyword for the outer class from an anonymous inner class?

I need to access the instance of the outer class within the anonymous inner class and did something like this. Can anyone clarify whether this is correct or not?

public class ClassA{

ClassA refernceOfClassA = this;  

    public void m(){
       //Do something
    }
    Runnable target = new Runnable(){
       public void run(){
           //Code goes here using the refernceOfClassA
           refernceOfClassA.m();      
       }
    };
}

您应该能够从内部类调用方法m()。

public class ClassA{    
    public void m(){
       //Do something
    }
    Runnable target = new Runnable(){
       public void run(){
           //Code goes here using the refernceOfClassA
           m();      
       }
    };
}

You should be able to just call the method m() from the inner class.

public class ClassA{    
    public void m(){
       //Do something
    }
    Runnable target = new Runnable(){
       public void run(){
           //Code goes here using the refernceOfClassA
           m();      
       }
    };
}
