How to Extract Names from a JSONArray in Android JSON Parsing?

Parsing JSONArrays in Android

When encountering JSON data that starts with a JSONArray, understanding the parsing process can be crucial. Here's how to approach the provided JSON to extract the "name" values:

You've correctly identified the JSONArray as "abridged_cast." However, your code is currently attempting to retrieve the "characters" data instead.

To get the names, we need to iterate over the JSONArray and extract the "name" field from each JSON object. Here's the fixed code snippet:

try {
    //JSON is the JSON code provided in the question

    JSONObject jsonResponse = new JSONObject(JSON);
    JSONArray cast = jsonResponse.getJSONArray("abridged_cast");
    List<String> allNames = new ArrayList<>();

    for (int i = 0; i < cast.length(); i++) {
        JSONObject actor = cast.getJSONObject(i);
        String name = actor.getString("name");
        allNames.add(name);
    }

    // Now you have the list of all names in allNames

} catch (JSONException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
Copy after login

The code iterates over the "abridged_cast" JSONArray, retrieves each JSON object, and extracts the "name" string. These names are stored in the allNames list, resulting in the string value: "Jeff Bridges,Charles Grodin,Jessica Lange,John Randolph,Rene Auberjonois."
