本文只做简单步骤以作记录.
1.添加依赖
// RxJava2.0
compile 'io.reactivex.rxjava2:rxjava:2.0.1'
compile 'io.reactivex.rxjava2:rxandroid:2.0.1'
// Retrofit
compile 'com.squareup.retrofit2:retrofit:2.3.0'
compile 'com.google.code.gson:gson:2.2.4'
compile 'com.squareup.retrofit2:converter-gson:2.3.0'// retrofit+gson
compile 'com.squareup.retrofit2:adapter-rxjava2:2.3.0' // Rxjava与Retrofit结合使用必须添加这个依赖
2.创建Builder,配置信息
Retrofit.Builder builder = new Retrofit.Builder();
builder.baseUrl(Api.SERVER_IP);
builder.addConverterFactory(GsonConverterFactory.create());
//设置Adapter
//不设置这个会报错:Could not locate call adapter for io.reactivex.Observable<retrofit2.Response<type··>>
builder.addCallAdapterFactory(RxJava2CallAdapterFactory.create());
3.构建Retrofit对象
Retrofit retrofit = builder.build();
4.配置参数和链接
public interface ApiInfo{
@POST(Api.GetCarBrand)
Observable<BrandResponse> getCarBrand();// 这里类型为Observable,泛型为JavaBean
}
5.发起请求
ApiInfo api = retrofit.create(ApiInfo.class);
Observable<BrandResponse> observable = api.getCarBrand();
observable.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Observer<BrandResponse>() {
@Override
public void onSubscribe(Disposable d) {
progressBar.setVisibility(View.VISIBLE);
}
@Override
public void onNext(BrandResponse brand) {
Log.e("ende","onNext:"+brand.toString());
}
@Override
public void onError(Throwable e) {
progressBar.setVisibility(View.GONE);
Log.e("ende","onError:"+e.toString());
}
@Override
public void onComplete() {
progressBar.setVisibility(View.GONE);
Toast.makeText(TowActivity.this,"请求完成",Toast.LENGTH_SHORT).show();
}
});
6.请求结果
onNext:BrandResponse{msg='', status=0, success=true, data=[DataBean{carBrandNm='宝马', carBrandNo='10'}, DataBean{carBrandNm='奔驰', carBrandNo='11'}, DataBean{carBrandNm='长城', carBrandNo='12'}]}
