# 学习RxJava+Retrofit+OkHttp框架的demo #
|
||
|
||
## 说明 ##
|
||
> 1.使用MVP架构
|
||
>
|
||
> 2.使用RxJava+Retrofit+OkHttp框架
|
||
|
||
## 使用解析 ##
|
||
> (1).ui --> UI层与Presenter层
|
||
>
|
||
> 1)*Activity -->activity
|
||
> I*View -->activity与presenter的交互接口
|
||
> *Presenter -->presenter
|
||
>
|
||
> 2).ui.base -->VP层super
|
||
> 2.1)BaseActivity -->所有activity super,里面包含加载框
|
||
> 2.2)BasePresenter -->所有presenter super,初始化View和Context
|
||
> 2.3)MvpActivty -->继承自BaseActivity,实例化presenter
|
||
>
|
||
> (2).model --> model层
|
||
>
|
||
> 1) BaseModel -->super model. 所有modelImpl的继承父类
|
||
>
|
||
> 2) model 接口 -->网络请求方法
|
||
> (3).bean --> 实体，包含普通bean,数据库entity、返回结果Result等
|
||

|
||
> (4).sys --> 系统（全局）级的处理
|
||

|
||
> (5).utils --> 工具包
|
||
|
||
## 使用步骤 ##
|
||
1.创建activity继承MvpActivity
|
||
> (1). ceatePresenter()实例化presenter
|
||
|
||
```
|
||
@Override
|
||
protected MainPresenter ceatePresenter() {
|
||
return new MainPresenter(subscription);
|
||
}
|
||
```
|
||
> (2). onInitLayoutBefore()加载layout
|
||
|
||
```
|
||
@Override
|
||
protected void onInitLayoutBefore() {
|
||
loadUI(this, R.layout.activity_main);
|
||
}
|
||
```
|
||
> (3). activity中onInitLayoutAfter()之后调用objBeanPresenter.*()方法
|
||
|
||
```
|
||
@Override
|
||
protected void onInitLayoutAfter() {
|
||
showLoadingDialog();//显示加载框
|
||
objBeanPresenter.loadInit();//到presenter去处理逻辑（加载数据）
|
||
}
|
||
```
|
||
> (4).请求结果（更改UI）数据和隐藏加载框的处理放回UI(activity)处理，通过presenter调用I*View接口实现回调
|
||
|
||
```
|
||
@Override
|
||
public void updateInit(String resultStr) {
|
||
hideLoadingDialog();
|
||
pptIcoListAll.setText(resultStr);
|
||
}
|
||
```
|
||
2.presenter
|
||
> (1).调用model请求数据
|
||
|
||
```
|
||
public void loadInit() {
|
||
/***
|
||
* 请求第一种方式
|
||
*/
|
||
subscription = PptIcoImpl.getPptIco()//获取PptIco model实例
|
||
.listALL()//请方法
|
||
.subscribeOn(Schedulers.io())
|
||
.observeOn(AndroidSchedulers.mainThread())
|
||
.subscribe(getInitObservable(ResultPptIcoGsonFormat.class));
|
||
//观察者模式订阅(创建观察者 (返回数据类型 ))
|
||
}
|
||
```
|
||
> (2).创建观察者级回调处理
|
||
|
||
```
|
||
private <S> BaseObserver getInitObservable(final Class<S> resultDataClass) {
|
||
return new BaseObserver<ResultData<S>>(new BaseObserver.HttpCallBack<ResultData<S>>() {
|
||
@Override
|
||
public void onComplete(int code, ResultData<S> resultDataClass) {
|
||
onComplete4Init(code, resultDataClass);//okHttp请求网络之后回调
|
||
}
|
||
});
|
||
}
|
||
```
|
||
> (3).回调处理 *ps:根据自己的逻辑处理*
|
||
|
||
```
|
||
private <S> void onComplete4Init(int code, ResultData<S> resultDataClass) {
|
||
String resultStr = "";
|
||
switch (code) {
|
||
case 200://请求成功
|
||
Gson gson = new GsonBuilder().setPrettyPrinting().create();
|
||
String json = gson.toJson(resultDataClass.toString());
|
||
System.out.println(json);
|
||
Log.e("resule", json);
|
||
resultStr = json;
|
||
break;
|
||
case 500://请求失败
|
||
T.showShort(getContext(), getContext().getString(R.string.error_code_500));
|
||
break;
|
||
}
|
||
//返回到UI的处理 *ps: 更改UI数据通过view回调到UI(activity)*
|
||
IMainView view = getView();
|
||
if (view != null) {
|
||
view.updateInit(resultStr);
|
||
}
|
||
}
|
||
``` |
