RHttp 是基于 RxJava2 + Retrofit2 + OkHttp3 + RxLifecycle2 框架整合封装的网络请求框架
- 基本的get、post、put、delete、4种请求
- 单/多文件上传
- 断点续传下载
- 基本回调包含 onSuccess、onError、onCancel、onProgress（上传/下载）
- 支持自定义Callback
- 支持https
- 支持tag取消，也可取消全部
- 支持链式调用
- 支持表单格式，String，json格式数据提交请求
RHttp 很屌吗？算不上，基本满足应用开发的所有需求，代码很简洁，体积小，功能齐全。这就够了
- 基于主流网络框架 Retrofit2 + OkHttp3 作为底层框架
- 使用 RxJava2 处理异步事件，线程间切换逻辑
- 使用 RxLifecycle2 管理生命周期，再也不用担心 RxJava 使用不当造成内存泄漏
- 基础网络请求，数据转换为 String 并提供 onConvert 方法提供开发者自定义转化数据
- 上传带进度回调，多文件情况下，可以区分当前文件下标
- 断点续传大文件，多种下载状态满足不同下载需求
new RHttp.Builder()
.post() //请求方式
.apiUrl("user/login") //接口地址
.addParameter(parameter) //参数
.addHeader(header) //请求头
.lifecycle(this) //自动管理生命周期，可以不传，如果未及时取消RxJava可能内存泄漏
.build()
.request(new HttpCallback<UserBean>() {
@Override
public UserBean onConvert(String data) {
/*数据解析转换*/
//String 转为 Response（自定义）
Response response = new Gson().fromJson(data, Response.class);
// Response 转为 JavaBean（目标对象）
UserBean userBean = new Gson().fromJson(response.getResult(), UserBean.class);
return userBean;
}
@Override
public void onSuccess(UserBean value) {
//do sth.
}
@Override
public void onError(int code, String desc) {
//do sth.
}
@Override
public void onCancel() {
//do sth.
}
});
MVP 是 MVC 框架的升级版本，通过 Presenter 桥梁连接 View 和 Model，使得模块之间更好的解耦

P[] getPresenterArray() 返回 Presenter 数组，可用于一个Activity 对应多个 Presenter 问题
