是否有某种方式,通过'方式',我的意思是使用rx运算符,转换每个HashMap值(将hashmap键设置为值字段)并进入新的Hashmap或ArrList?
Observable<HashMap<String,Allergy>> observable = MyREST.getsAllergiesApi().getAllAllergiesRx();
observable
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.unsubscribeOn(Schedulers.io())
.subscribe(new Subscriber<HashMap<String, Allergy>>() {
@Override
public void onCompleted() {
Log.i(TAG,"onCompleted");
}
@Override
public void onError(Throwable e) {
Log.i(TAG,"onError");
}
@Override
public void onNext(HashMap<String, Allergy> allergies) {
mView.displayAllergies(allergies);
Log.i(TAG,"onNeXt");
}
});

您可以在map
中使用任何经典转换,也可以展平,映射和收集值。
Observable<Map<String, Allergy>> source = ...
source.map(map -> {
HashMap<Allergy, Allergy> newMap = new HashMap<>();
for (Allergy a : map.values()) {
newMap.put(a, a);
}
return newMap;
})
.subscribe(...)
source.flatMapIterable(map -> map.values())
.toMap(v -> v)
.subscribe(...)
