How to Get JSON Array Within JSON Object?

Solution 1:

I guess this will help you.

JSONObject jsonObj = new JSONObject(jsonStr);

JSONArray ja_data = jsonObj.getJSONArray("data");
int length = jsonObj.length();
for(int i=0; i<length; i++) {
  JSONObject jsonObj = ja_data.getJSONObject(i);
  Toast.makeText(this, jsonObj.getString("Name"), Toast.LENGTH_LONG).show();

  // getting inner array Ingredients
  JSONArray ja = jsonObj.getJSONArray("Ingredients");
  int len = ja.length();

  ArrayList<String> Ingredients_names = new ArrayList<>();
  for(int j=0; j<len; j++) {
    JSONObject json = ja.getJSONObject(j);
    Ingredients_names.add(json.getString("name"));
  }
}

Solution 2:

Solved, use array list of string to get name from Ingredients. Use below code:

JSONObject jsonObj = new JSONObject(jsonStr);

//extracting data array from json string
JSONArray ja_data = jsonObj.getJSONArray("data");
int length = ja_data.length();

//loop to get all json objects from data json array
for(int i=0; i<length; i++){
    JSONObject jObj = ja_data.getJSONObject(i);
    Toast.makeText(this, jObj.getString("Name"), Toast.LENGTH_LONG).show();
    // getting inner array Ingredients
    JSONArray ja = jObj.getJSONArray("Ingredients");
    int len = ja.length();
    ArrayList<String> Ingredients_names = new ArrayList<>();
    for(int j=0; j<len; j++){
        JSONObject json = ja.getJSONObject(j);
        Ingredients_names.add(json.getString("name"));
    }
}

Solution 3:

JSONObject jsonObject =new JSONObject(jsonStr);
JSONArray jsonArray = jsonObject.getJSONArray("data");
for(int i=0;i<jsonArray.length;i++){
    JSONObject json = jsonArray.getJSONObject(i);
    String id = json.getString("id");
    String name=json.getString("name");
    JSONArray ingArray = json.getJSONArray("Ingredients") // here you are going   to get ingredients
    for(int j=0;j<ingArray.length;j++){
        JSONObject ingredObject= ingArray.getJSONObject(j);
        String ingName = ingredObject.getString("name");//so you are going to get   ingredient name
        Log.e("name",ingName); // you will get 
   }
}

Solution 4:

JSONObject jsonObj = new JSONObject(jsonString);

JSONArray jArray = jsonObj.getJSONArray("data");
int length = jArray.length();

   for(int i=0; i<length; i++)
      {
        JSONObject jObj = jArray.getJSONObject(i);
        String id = jObj.optString("id");
        String name=jObj.optString("name");

        JSONArray ingredientArray = jObj.getJSONArray("Ingredients");
        int size = ingredientArray.length();
        ArrayList<String> Ingredients = new ArrayList<>();

            for(int j=0; j<size; j++)
               {
                    JSONObject json = ja.getJSONObject(j);
                    Ingredients.add(json.optString("name"));
                }
