android retrofit和rxjava的网络请求
去年的时候好多公司就已经使用rxjava和retrofit了，最近自自己学习了一下，感觉真的是很好用，让自己的网络请求变得更简单了，而且封装性极强。
首先做一下准备工作，导入需要引用的文件
compile 'com.android.support:appcompat-v7:25.1.0' testcompile 'junit:junit:4.12' compile 'io.reactivex:rxjava:1.1.0' compile 'io.reactivex:rxandroid:1.1.0' compile 'com.squareup.retrofit2:retrofit:2.0.0-beta4' compile 'com.squareup.retrofit2:converter-gson:2.0.0-beta4' compile 'com.squareup.retrofit2:adapter-rxjava:2.0.0-beta4' compile 'com.google.code.gson:gson:2.6.2' compile 'com.jakewharton:butterknife:7.0.1' compile 'com.android.support:recyclerview-v7:25.1.0'
网络请求的地址：https://api.douban.com/v2/movie/top250?start=0&count=10
添加网络请求权限
<uses-permission android:name="android.permission.internet"/>
首先看一下retrofit的使用基本用法
创建一个接口类movieservice 对网络接口进行请求这里写代码片
构建网络请求
public interface movieservice {
@get("top250")
call<moviebean> gettopmovie(@query("start")int start, @query("count")int count);
}
string baseurl="https://api.douban.com/v2/movie/";
retrofit retrofit = new retrofit.builder()
.baseurl(baseurl)
.addconverterfactory(gsonconverterfactory.create())
.addcalladapterfactory(rxjavacalladapterfactory.create())
.build();
movieservice service = retrofit.create(movieservice.class);
service.gettopmovie(0,10)
.subscribeon(schedulers.io())
.observeon(androidschedulers.mainthread())
.subscribe(new subscriber<moviebean>() {
@override
public void oncompleted() {
toast.maketext(mainactivity.this, "get top movie completed", toast.length_short).show();
}
@override
public void onerror(throwable e) {
resulttv.settext(e.getmessage());
}
@override
public void onnext(moviebean moviebean) {
resulttv.settext(moviebean.gettitle());
}
});
call<moviebean> call = service.gettopmovie(0, 10);
call.enqueue(new callback<moviebean>() {
@override
public void onresponse(call<moviebean> call, response<moviebean> response) {
moviebean body = response.body();
resulttv.settext(response.body().gettitle());
system.out.println("成功"+response.body().getcount());
}
@override
public void onfailure(call<moviebean> call, throwable t) {
resulttv.settext(t.getmessage());
}
});
现在看看我们的布局文件mainactivity的xml
<?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_main" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="ledon.com.retrofitdemo.mainactivity"> <button android:id="@+id/click_me_bn" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignparentbottom="true" android:padding="5dp" android:text="获取数据" android:textsize="16sp"/> <listview android:id="@+id/result_tv" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_above="@id/click_me_bn" android:textsize="16sp"/> </relativelayout>
接下来就看看怎么样和rxjava的完美结合了。
首先改造一下movieservice这个接口
public interface movieservice {
@get("top250")
observable<moviebean> gettopmovie(@query("start")int start, @query("count")int count);
}
然后看一下我们需要创建一个httpmethods关于一个http的请求方法
package ledon.com.retrofitdemo.api;
import java.util.list;
import java.util.concurrent.timeunit;
import javax.security.auth.subject;
import ledon.com.retrofitdemo.moviebean;
import okhttp3.okhttpclient;
import retrofit2.retrofit;
import retrofit2.adapter.rxjava.rxjavacalladapterfactory;
import retrofit2.converter.gson.gsonconverterfactory;
import rx.subscriber;
import rx.android.schedulers.androidschedulers;
import rx.functions.func1;
import rx.schedulers.schedulers;
/**
* created by administrator on 2017/3/9.
*/
public class httpmethods {
public static final string base_url="https://api.douban.com/v2/movie/";
private static final int default_timeout=5;
private retrofit retrofit;
private movieservice movieservice;
//私有化构造方法
private httpmethods(){
//手动创建一个okhttpclient并设置超时时间
okhttpclient.builder builder = new okhttpclient.builder();
builder.connecttimeout(default_timeout, timeunit.seconds);
retrofit=new retrofit.builder()
.client(builder.build())
.addconverterfactory(gsonconverterfactory.create())
.addcalladapterfactory(rxjavacalladapterfactory.create())
.baseurl(base_url)
.build();
movieservice = retrofit.create(movieservice.class);
}
//在访问httpmethods时候创建单例
private static class singletonholder{
private static final httpmethods instance=new httpmethods();
}
//获取单例
public static httpmethods getinstance(){
return singletonholder.instance;
}
public void gettopmovie(subscriber<moviebean>subscriber, int start, int count){
movieservice.gettopmovie(start, count)
.subscribeon(schedulers.io())
.unsubscribeon(schedulers.io())
.observeon(androidschedulers.mainthread())
.subscribe(subscriber);
}
}
so，很简单，我们的结合之路已经完成，另附源代码
