本文实例为大家分享了rxjava retrofit实现购物车展示的具体代码，供大家参考，具体内容如下
先给大家展示一下效果图
框架结构：
1.项目框架：mvp，图片加载用fresco，网络请求用okhttp+retrofit实现（自己封装，加单例模式），
2.完成购物车数据添加（如果接口无数据，可用接口工具添加数据），
3.自定义view实现加减按钮，每次点击加减，item中的总数及总价要做出相应的改变。
4.当数量为1时，点击减号，数量不变，吐司提示用户最小数量为1。
5.底部总数及总价为所有item项中的总价及总数，每个item中数量价格的更改，底部总价总数要与之联动
6.实现单选反选全选功能，首次进入默认全选，item未选中时总数及总价不计入底部数据，改变选中状态时，底部总数及总价能做出正确修改
7.点击删除按钮，删除item，底部总数及总价能做出正确修改，接口数据删除。
添加所需要的依赖和联网权限
compile 'com.squareup.retrofit2:retrofit:2.0.0-beta4'//retrofit2所需要的包 compile 'com.squareup.retrofit2:converter-gson:2.0.0-beta4'//converterfactory的gson依赖包 compile 'com.squareup.retrofit2:converter-scalars:2.0.0-beta4'//converterfactory的string依赖包 compile 'io.reactivex.rxjava2:rxjava:2.1.3' compile 'io.reactivex.rxjava2:rxandroid:2.0.1' compile 'com.squareup.retrofit2:adapter-rxjava2:2.3.0' compile 'de.greenrobot:eventbus:3.0.0-beta1' compile 'com.facebook.fresco:fresco:0.11.0'
<uses-permission android:name="android.permission.internet" />
在使用mvp模式前先分包
net包
api
我要评论
public class api {
public static string host="http://120.27.23.105/product/";
}
serviceapi
public interface serviceapi {
@get("getproductdetail")
flowable<xqbean> getxq(@query("pid")int pid, @query("source")string str);
@get("addcart")
flowable<addcart> getmsg(@query("uid")int uid, @query("pid")int pid, @query("source")string str);
@get("getcarts")
flowable<cartbean> getcart(@query("uid")int uid, @query("source")string str);
}
成功的接口
public interface onnetlisenter<t> {
void success(t t);
}
retrofit的封装
public class retrofithepler {
public static okhttpclient okhttpclient;
public static serviceapi serviceapi;
/**
* 优先执行
*/
static {
getokhttpclient();
}
public static okhttpclient getokhttpclient(){
if(okhttpclient==null){
synchronized (okhttpclient.class){
if(okhttpclient==null){
okhttpclient=new okhttpclient();
}
}
}
return okhttpclient;
}
public static serviceapi getserviceapi(){
if(serviceapi==null){
synchronized (okhttpclient.class){
if(serviceapi==null){
serviceapi=oncreate(serviceapi.class,api.host);
}
}
}
return serviceapi;
}
public static <t> t oncreate(class<t>tclass,string url){
retrofit retrofit = new retrofit.builder()
.baseurl(url)
.addconverterfactory(gsonconverterfactory.create())
.client(okhttpclient)
.addcalladapterfactory(rxjava2calladapterfactory.create())
//.addcalladapterfactory(rxjava2calladapterfactory.create())
