java - 如何从回调函数返回某些内容给父函数

Question

这就是我要做的

UploadCompleteListener 是一个充当回调的自定义接口(interface)。

@Overrider
public Result doWork() {

        mUpLoadDataService.uploadInspectionData(new UpLoadDataService.UploadCompleteListener() {
            @Override
            public void uploadComplete() {
                    return Result.success(); //this is what I want to do
            }

            @Override
            public void uploadFailed(String reason) {
                return Result.failure(); //this is what I want to do
            }
        });

        return null;
    }

可能吗？

如果可能的话，请尽快回复。如果您需要，我可以提供更多详细信息。

** 这对我有用 **

 @NonNull
    @Override
    public Result doWork() {
        final Result[] result = new Result[1];
        mUpLoadDataService.uploadInspectionData(new UpLoadDataService.UploadCompleteListener() {
            @Override
            public void uploadComplete() {
                    result[0] = Result.success(); //this is what I want to do
            }

            @Override
            public void uploadFailed(String reason) {
                result[0] = Result.failure(); //this is what I want to do
            }
        });

        return result[0];
    }
