我使用改造2来获取JSON Array
并且我想创建新的ManagerListAdapter
(它是RecyclerView
的适配器)并传递ArrayList
(我从JSON获得) )在构造函数中。
目前我在onResponse
成功获得此列表。
但这是另一个主题。
将它转移到主线程的最佳方法是什么? 也许我需要使用RxJava和RxAndroid?
private void initRecyclerView() {
RecyclerView managersRecyclerView = (RecyclerView) view.findViewById(R.id.managersRecyclerView);
managersRecyclerView.setLayoutManager(new LinearLayoutManager(getContext()));
managersRecyclerView.setAdapter(new ManagerListAdapter(getManagers()));
// getRemoteManagers();
}
private void getRemoteManagers() {
ApiObject client = ServiceGenerator.createService(ApiObject.class);
Call<List<ManagerDTO>> call = client.getManagers();
call.enqueue(new Callback<List<ManagerDTO>>() {
@Override
public void onResponse(Call<List<ManagerDTO>> call, Response<List<ManagerDTO>> response) {
if (response.isSuccessful()) {
List<ManagerDTO> managers = response.body(); //I want to add this List in RecyclerAdapter
sortManagers(managers);
}
}
@Override
public void onFailure(Call<List<ManagerDTO>> call, Throwable t) {
}
});
}
private List<ManagerDTO> getManagers() {
//It's for test.
List<ManagerDTO> managers = new ArrayList<>();
managers.add(new ManagerDTO("Alex Pavlov", 100));
managers.add(new ManagerDTO("Ivan Pavlov", 95));
managers.add(new ManagerDTO("Petr Pavlov", 99));
managers.add(new ManagerDTO("Stepan Pavlov", 100));
managers.add(new ManagerDTO("Azik Pavlov", 100));
managers.add(new ManagerDTO("Azik Myand", 100));
managers.add(new ManagerDTO("Azik Specca", 50));
managers.add(new ManagerDTO("Azik Kane", 0));
managers.add(new ManagerDTO("Azik McDonald", 99));
managers.add(new ManagerDTO("Azik Jagr", 1));
sortManagers(managers);
return managers;
}
答案 0 :(得分:0)
我们可以将RxJava
和RxAndroid
与Retrifit2
一起使用。
<强> ServiceGenerator:强>
private static Retrofit.Builder builder =
new Retrofit.Builder()
.addCallAdapterFactory(RxJavaCallAdapterFactory.createWithScheduler(Schedulers.io()))
.baseUrl(Const.URL.UrlService)
.addConverterFactory(JacksonConverterFactory.create());
public static <S> S createService(Class<S> serviceClass) {
Retrofit retrofit = builder.build();
return retrofit.create(serviceClass);
}
}

ApiObject service = ServiceGenerator.createService(ApiObject.class);
Observable<List<ManagerDTO>> observManagers = service.getManagers();
observManagers
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())

//Copy to db
RealmHelper helper = new RealmHelper(context);
helper.copyToRealmOrUpdate(managers);
Log.e("RealmCopy", "it's ok");
}
});
