json-deserialization

问题 So I have a JSON string where I just want to read a specific value. How do I just pick " Read me please! " from string below? var readString = /*Read me please!*/ JSON string: "{\"aString\":\"Read me please!\"}" For better understanding, how do I do the same here? (just " Read me please! "): "{\"Result\": { \"aString\":\"Read me please!\", \"anotherString\":\"Dont read me!\" } }" If both alternative have different solution I would like to know both. PS: I do not wish to save the value into

问题 I am trying to decode data from a Firebase DataSnapshot so that it can be decoded using JSONDecoder. I can decode this data fine when I use a URL to access it with a network request (obtaining a Data object). However, I want to use the Firebase API to directly obtain the data, using observeSingleEvent as described on this page. But, when I do this, I cannot seem to convert the result into a Data object, which I need to use JSONDecoder. Is it possible to do the new style of JSON decoding with

问题 The result variable contains corrected parsed JSON. But after deserialization List contains correct amount of items but all of them are empty. How to fix it? Gson gson = new Gson(); List<UnitView> unitViews = new ArrayList<UnitView>(); // https://stackoverflow.com/questions/5554217/google-gson-deserialize-listclass-object-generic-type Type typeToken = new TypeToken<List<UnitView>>() { }.getType(); unitViews = gson.fromJson(result,typeToken); Even if I do like UnitView[] unitViews = gson
