android - Moshi HashMap deserializer

Question

I don't know if it is possible to deserialise arrays into hashMap i have got json :

"additionalProperties": [
{
  "$type": "Tfl.Api.Presentation.Entities.AdditionalProperties, Tfl.Api.Presentation.Entities",
  "category": "Description",
  "key": "TerminalName",
  "sourceSystemKey": "BikePoints",
  "value": "200017",
  "modified": "2016-05-19T12:02:39.82"
}
........
]

and for that json i have got list :

private List<AdditionalProperties> additionalProperties;

everything works perfect but how store that json in HashMap where Key is "key" (TerminalName)"

private HashMap<String,AdditionalProperties> additionalProperties;

Answer 1

Moshi supports fields declared as Map but not as HashMap. This way Moshi can use a different implementation of Map that’s more appropriate than HashMap for decoded JSON. If you change your field’s type to Map<String,AdditionalProperties> it should work.
