在接口实现中获取自我实例

Question

我是java/android新手。

我有有2种方法的服务类....准备（）和执行（）..

都是异步调用，所以我要做的就是，准备调用（）和等待prepareFinished我听....当准备方法结束时，用于相同的服务实例我想调用execute（）方法.....

按照下面我尝试：

for(int idx = 0; idx < services.length; idx++) 
{ 
    MyService instance = services[idx]; 
    instance.setDataReadListener(new AsyncDataReadListener() { 
     @Override 
     public void prepareFinished(ServiceInfo info) { 

      //I would like to get the self instannce here to call another 
         //method after been prepared. something like::: sender.execute() 

     } 
    }); 
} 

//In a button click I call above, for each service its prepared I would like another method of the same service instance to be called: 
for(int idx = 0; idx < services.length; idx++) 
{ 
    MyService instance = services[idx]; 
    //async call 
    instance.prepare(); 
} 

我该如何实现它？

Tks。

Answer 1

制作实例决赛：

final MyService instance = services[idx]; 

，并且可以调用instance.execute()内prepareFinished。

Answer 2

让instancefinal并直接引用它：

for(int idx = 0; idx < services.length; idx++) 
{ 
    final MyService instance = services[idx]; 
    instance.setDataReadListener(new AsyncDataReadListener() { 
     @Override 
     public void prepareFinished(ServiceInfo info) { 
      instance.execute() 
     } 
    }); 
} 

Answer 3

有什么不对这种做法？

final MyService instance = services[idx]; 
instance.setDataReadListener(new AsyncDataReadListener() { 
    @Override 
    public void prepareFinished(ServiceInfo info) { 

     instance.execute(); 
    } 
});
