JSON Array Parsing in Android
When faced with parsing a JSON array in Android, it's essential to differentiate it from its counterpart, the JSON object. Unlike JSON objects, which are represented as key-value pairs, JSON arrays are an ordered collection of values.
Example JSON Array:
[{"name":"name1","url":"url1"},{"name":"name2","url":"url2"},...]
Parsing a JSON Array:
To parse a JSON array, utilize the following steps:
Create a new JSONArray object using the JSON string:
JSONArray jsonarray = new JSONArray(jsonStr);
Iterate through the array elements using a loop:
for (int i = 0; i < jsonarray.length(); i++) { // Get the current element as a `JSONObject` JSONObject jsonobject = jsonarray.getJSONObject(i); // Extract values from the `JSONObject` String name = jsonobject.getString("name"); String url = jsonobject.getString("url"); }
By following these steps, you can effortlessly parse JSON array data in your Android applications.
