MainActivity必须声明为抽象或实现接口X

Question

I have the interface

public interface MyInterface {

    public void myTask (ServiceHandler.SongInfo[] songInfo);
}

I have the ServiceHandler.SongInfo class

public class SongInfo {
        public String wrapperType;
        public String kind;
        public Integer artistId;
        public Integer collectionId
        //etc
    }

I have the decleration

public class MainActivity extends AppCompatActivity implements MyInterface {

    //... Everything else 

    @Override 
    void myTask(SongInfo[] songInfo){

    }

 }

But I sill get the error unless I comment out this line in my interface

public interface MyInterface {

    //public void myTask (ServiceHandler.SongInfo[] songInfo);
}

What does it mean?

Answer 1

在实现参数songInfo[]更改为ServiceHandler.SongInfo[]
