Android Retrofit和Rxjava的网络请求

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

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 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() {

@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 call = service.getTopMovie(0, 10);

call.enqueue(new Callback() {

@Override

public void onResponse(Call call, Response response) {

MovieBean body = response.body();

resultTV.setText(response.body().getTitle());

System.out.println("成功"+response.body().getCount());

}

@Override

public void onFailure(Call call, Throwable t) {

resultTV.setText(t.getMessage());

}

});

现在看看我们的布局文件MainActivity的xml

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">

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">

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"/>

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"/>

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"/>

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 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(Subscribersubscriber, 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
