如何扩展 Retrofit 2.0 调用? [英] How can I extend a Retrofit 2.0 Call?

问题描述

我想实现这样的目标:

MyCall<MyResponse> call = service.login(loginRequest);

call.enqueue(
    new Runnable() {
        @Override
        public void run() {
            // onResponse
            }
        }, new Runnable() {
            @Override
            public void run() {
                // onFailure
            }
    });

这样当我必须拨打电话时，我不需要解析每个回调中的响应，并且代码更轻巧且可重用.

so that when I have to make a call I don't need to parse the response in each callback and the code is a little lighter and reusable.

我尝试了此代码段中的代码，但出现错误:

I tried the code from this snippet but I get the error:

无法为 XXXX 创建呼叫适配器.

我错过了什么?

推荐答案

我没有扩展 Call 但我扩展了 Callback，这也有助于使 代码更轻巧且可重用.

I did not extend Call but I extend Callback, it's also help to make the code is a little lighter and reusable.

public abstract class CustomCallback<T> implements Callback<T> {

    @Override
    public void onResponse(final Response<T> response, Retrofit retrofit) {
        Runnable runnable = new Runnable() {
            @Override
            public void run() {
                onRequestSuccess(response);
            }
        };
        runnable.run();
    }

    @Override
    public void onFailure(final Throwable t) {
        Runnable runnable = new Runnable() {
            @Override
            public void run() {
                onRequestFail(t);
            }
        };
        runnable.run();

    }

    public abstract void onRequestSuccess(Response<T> response);

    public abstract void onRequestFail(Throwable t);

}

然后当你调用 enqueue() 时:

call.enqueue(new CustomCallback<YourObject>() {
            @Override
            public void onRequestSuccess(final Response<YourObject> response)
            {
            }

            @Override
            public void onRequestFail(final Throwable t) {

            }
        });
