今天就跟大家聊聊有关如何在Android中利用Retrofit与Rxjava实现网络请求,可能很多人都不太了解,为了让大家更加了解,小编给大家总结了以下内容,希望大家根据这篇文章可以有所收获。
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
package ledon.com.retrofitdemo; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.support.v7.widget.LinearLayoutManager; import android.support.v7.widget.RecyclerView; import android.widget.Button; import android.widget.ListView; import android.widget.RelativeLayout; import android.widget.Toast; import java.util.List; import butterknife.Bind; import butterknife.ButterKnife; import butterknife.OnClick; import ledon.com.retrofitdemo.adapter.MovieAdapter; import ledon.com.retrofitdemo.api.HttpMethods; import rx.Subscriber; public class MainActivity extends AppCompatActivity { @Bind(R.id.click_me_BN) Button clickMeBN; @Bind(R.id.result_TV) ListView resultTV; @Bind(R.id.activity_main) RelativeLayout activityMain; private Subscriber<MovieBean> subscriber; private List<MovieBean.SubjectsBean> list; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); ButterKnife.bind(this); //resultTV.setAdapter(); } //进行网络请求 private void getMovie() { subscriber = 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) { // List<MovieBean.SubjectsBean> subjects = movieBean.getSubjects(); list=movieBean.getSubjects(); MovieAdapter movieAdapter=new MovieAdapter(MainActivity.this,list); resultTV.setAdapter(movieAdapter); //resultTV.setText(movieBean.getTitle()); } }; HttpMethods.getInstance().getTopMovie(subscriber, 0, 10); /* 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()); } });*/ } @OnClick(R.id.click_me_BN) public void onClick() { getMovie(); } }
package ledon.com.retrofitdemo; import java.util.List; /** * Created by Administrator on 2017/3/9. */ public class MovieBean { /** * count : 10 * start : 0 * total : 250 * subjects :
