Android Retrofit和Rxjava的網(wǎng)絡請求

去年的時候好多公司就已經(jīng)使用Rxjava和Retrofit了，最近自自己學習了一下，感覺真的是很好用，讓自己的網(wǎng)絡請求變得更簡單了，而且封裝性極強。

首先做一下準備工作，導入需要引用的文件

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'

網(wǎng)絡請求的地址：https://api.douban.com/v2/movie/top250?start=0&count=10

添加網(wǎng)絡請求權限

首先看一下Retrofit的使用基本用法

創(chuàng)建一個接口類MovieService 對網(wǎng)絡接口進行請求這里寫代碼片

構建網(wǎng)絡請求

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());

}

});

現(xiàn)在看看我們的布局文件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">

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="獲取數(shù)據(jù)"

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"/>

接下來就看看怎么樣和RxJava的完美結合了。

首先改造一下MovieService這個接口

public interface MovieService {

@GET("top250")

Observable getTopMovie(@Query("start")int start, @Query("count")int count);

}

然后看一下我們需要創(chuàng)建一個HttpMethods關于一個http的請求方法

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;

//私有化構造方法

private HttpMethods(){

//手動創(chuàng)建一個okhttpClient并設置超時時間

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);

}

//在訪問httpmethods時候創(chuàng)建單例

private static class SingletonHolder{

private static final HttpMethods INSTANCE=new HttpMethods();

}

//獲取單例

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，很簡單，我們的結合之路已經(jīng)完成，另附源代碼
