Retrofit + rxjava 使用案例

配置:

 retrofit 到 rxjava 转化库

compile 'io.reactivex:rxandroid:1.9.0'
compile 'io.reactivex:rxjava:1.9.0'
compile 'com.squareup.retrofit2:adapter-rxjava:2.0.0'

Retrofit 配置:
Retrofit retrofit = new Retrofit.Builder().baseUrl(BASE_URL).client(client)
                .addConverterFactory(GsonConverterFactory.create())
                .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
                .build();

案例1: 与Retrofit 配合使用

//接口:    
@FormUrlEncoded @POST("userv2/login") Observable<Base<User>> login(@Field("mobile") String mobile,@Field("password") String password,@Field("deviceType") String deviceType);
使用:
RestClient.getApiService().login(phone, encryptPassword,"0").subscribeOn(Schedulers.io()).observeOn(AndroidSchedulers.mainThread()) .subscribe(new Subscriber<Base<User>>() { @Override public void onCompleted() { } @Override public void onError(Throwable e) { } @Override public void onNext(Base<User> userBase) { } });

案例2: 搜索框搜索相关列表,自动延迟400ms, 

//搜索并回显
mSearchResultsSubject = PublishSubject.create(); mTextWatchSubscription = mSearchResultsSubject .debounce(400, TimeUnit.MILLISECONDS) .observeOn(Schedulers.io()) .map(new Func1<String, List<String>>() { @Override public List<String> call(String s) { return mRestClient.searchForCity(s); } }) .observeOn(AndroidSchedulers.mainThread()) .subscribe(new Observer<List<String>>() { @Override public void onCompleted() { } @Override public void onError(Throwable e) { } @Override public void onNext(List<String> cities) { handleSearchResults(cities); } });
// 文本框自动输入 mSearchInput.addTextChangedListener(new TextWatcher() { @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { } @Override public void onTextChanged(CharSequence s, int start, int before, int count) { mSearchResultsSubject.onNext(s.toString()); } @Override public void afterTextChanged(Editable s) { } });  

案例3:发送验证码后,倒计时功能

final long count = TOTAL_TIME / 1000;
        Observable.interval(0, 1, TimeUnit.SECONDS)//设置0延迟,每隔一秒发送一条数据
                .take((int) (count + 1)) //设置总共发送的次数
                .map(new Func1<Long, Long>() { //将数值倒置
                    @Override
                    public Long call(Long aLong) {
                        return count - aLong; //
                    }
                })
                .subscribeOn(Schedulers.computation())
                // doOnSubscribe 执行线程由下游逻辑最近的 subscribeOn() 控制,下游没有 subscribeOn() 则跟Subscriber 在同一线程执行
                //执行计时任务前先将 button 设置为不可点击
                .doOnSubscribe(new Action0() {
                    @Override
                    public void call() {
                        mStart.setEnabled(false);//在发送数据的时候设置为不能点击
                        mStart.setBackgroundColor(Color.GRAY);//背景色设为灰色
                    }
                })
                .observeOn(AndroidSchedulers.mainThread())//操作UI主要在UI线程
                .subscribe(new Subscriber<Long>() {
                    @Override
                    public void onCompleted() {
                        mTvValue.setText(getResources().getString(R.string.done));
                        mStart.setEnabled(true);
                        mStart.setBackgroundColor(Color.parseColor("#f97e7e"));
                    }

                    @Override
                    public void onError(Throwable e) {
                        e.printStackTrace();
                    }

                    @Override
                    public void onNext(Long aLong) { //接收到一条就是会操作一次UI
                        String value = String.valueOf(aLong);
                        mTvValue.setText(value);
                    }
                });
