Get particular key value from json in android (kotlin)

Question

I'm beginner in android (Kotlin).I am getting the Following json from the HTTP Response.

{
    "status": 1,
    "userDetails": [
        {
            "AL_ID": "2",
            "User_Id": "admin",
            "User_Password": "admin",
            "Created_Date": "2020-07-30 11:23:55"
        }
    ],
    "lastlogin": "2020-08-20 12:29:47"
}

I want to get status value from this json. How to get it.

Answer 1

You can use the built-in JSONObject and do something as shown below.

val json = JSONObject(jsonString) // String instance holding the above json
val status = json.getInt("status")

Having said that, I'd recommend you to take a look at Gson (for JSON serialization and deserialization) and Retrofit (an HTTP client for Android).
