Android学习笔记--RetrofitCallback封装

RetrofitCallback

 call.enqueue(new Callback<TngouNewsModel>() {            @Override            public void onResponse(Call<TngouNewsModel> call, Response<TngouNewsModel> response) {            }            @Override            public void onFailure(Call<TngouNewsModel> call, Throwable t) {            }        });

一个标准Callback是这样的，在实际开发中我们还是要在onResponse加额外逻辑代码判断是否成功返回，于是有了以下的封装。

public abstract class RetrofitCallback<M> implements Callback<M> {    public abstract void onSuccess(M model);    public abstract void onFailure(int code, String msg);    public abstract void onThrowable(Throwable t);    public abstract void onFinish();    @Override    public void onResponse(Call<M> call, Response<M> response) {        if (response.isSuccessful()) {            onSuccess(response.body());        } else {            onFailure(response.code(), response.errorBody().toString());        }        onFinish();    }    @Override    public void onFailure(Call<M> call, Throwable t) {        onThrowable(t);        onFinish();    }}

在onResponse加了判断是否成功返回。我们把它用到我们的工程上

 call.enqueue(new RetrofitCallback<TngouNewsModel>() {            @Override            public void onSuccess(TngouNewsModel model) {            }            @Override            public void onFailure(int code, String msg) {            }            @Override            public void onThrowable(Throwable t) {            }            @Override            public void onFinish() {            }        });

回调一目了然了。
