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
