How to deserialize a list using GSON or another JSON library in Java?
(4 answers)
Closed 6 years ago.
Hi i serialized a list List<Show> list; to pass it through an intent using
String listSerializedToJson = new Gson().toJson(mShowAdapter.getList());
Now In the other activity I got the json like this:
String listSerializedToJson = getIntent().getExtras().getString("LIST_OF_OBJECTS");
How do I transform it back into a List<Show> list;?
Type listType = new TypeToken<ArrayList<Show>>(){}.getType();
List<Show> yourClassList = new Gson().fromJson(listSerializedToJson , listType);

Deserialization of generic collections with Gson

Closed 4 years ago.
I have this JSON string:
[
{
"k":"number",
"v":"055 543 8679\n"
},
{
"k":"hours",
"v":"8:00AM - 9:00PM"
}
]
And I'm trying to parse it using Gson:
val customFields = Gson().fromJson(food.customFields, ArrayList<CustomField>()::class.java)
But somehow when I view it in breakpoint mode, it is parsed as a LinkedTreeMap
try thisval customFields = new Gson().fromJson(food.customFields, CustomField.class);

How to parse this with no any object name
There are different methods to parse json object
Simple way
JSONObject myJson = new JSONObject(yourJsonString);
String quote = myJson. getString("quote");
String author = myJson. getString("author");
Another and recomented way is parse json using Gson
For this you can refer below links
How to parse json parsing Using GSON in android
https://www.journaldev.com/2321/gson-example-tutorial-parse-json
How to do it ?
If you meet {} in your code , you can use JSONObject to parse it .
If you meet [] in your code , you can use JSONArray to parse it .
And if you meet [] in your code , you can use for loop to get value in it .
And you should use try catch in your code .
Try this .
try {
JSONObject jsonObject = new JSONObject(response);
String author = jsonObject.getString("author");
String quote = jsonObject.getString("quote");
} catch (JSONException e) {
e.printStackTrace();
}
This is absolutely normal json.
JSONObject json = new JSONObject(your_json);
String quote = json.getString("quote");
String author = json.getString("author");

I have a string builder in Android which is filled with data from a database, and I want to display that data using a list view. For that I want to covert string builder into an array of strings. Can somebody help me in this conversion, or suggest to me some other technique.
Here you can find Link
tempArray = sb.toString().split("ABCABC"); will split the string and return an array of strings for each line.
Try this :
String sbString = sb.ToString();
String[] ary = "abc".split("TABTAB");
