Java 获取接口实现内部的自实例

我是java/android新手

我有一个服务类，它有两个方法。。。。准备并执行

这两个都是异步调用，所以我要做的是，调用prepare并等待prepareFinished，我正在听。。。。当prepare方法完成时，对于同一个服务实例，我想调用execute方法

请按照我下面的尝试：

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();
}

我怎样才能做到呢

Tks.

使实例成为最终实例：

final MyService instance = services[idx];

您可以在prepareFinished内调用instance.execute。

将实例设为final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()
        }
    });
}

这种方法有什么问题

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

       instance.execute();
    }
});
