inThe ci-dessus JSON je veux analyser les valeurs des « options de produits » ... qui ne correspond pas tous les objets, j'ai essayé « optJSONArray » mais pas obtenir la solution, je l'ai essayé comme ci-dessous, qui est ne fonctionne pas, S'il vous plaît aidez-moi à résoudre ce .. main.jaa
try {
if (jsonStr != null) {
jsonObj = new JSONObject(jsonStr);
if (jsonObj.has("product")) {
subCategories = jsonObj.getJSONArray("product");
if (subCategories != null
&& subCategories.length() != 0) {
// looping through All Contacts
for (int i = 0; i < subCategories.length(); i++) {
JSONObject c = subCategories.getJSONObject(i);
sub_id = c.getString("id");
sub_name = c.getString("name");
thumb_image = c.getString("thumb_image");
big_image = c.getString("big_image");
resultArray.add(big_image);
if (c.has("product_options")) {
JSONArray product_optionsarray = c
.optJSONArray("product_options");
for (int j = 0; j < product_optionsarray
.length(); j++) {
JSONObject c1 = product_optionsarray
.optJSONObject(j);
if (c1.has("option_name"))
option_name = c1
.optString("option_name");
System.out
.println("::::::::::::::::Option name::::::"
+ option_name);
if (c1.has("option_value"))
option_value = c1
.optString("option_value");
System.out
.println("::::::::::::::::Optionvalue::::::"
+ option_value);
}
}
HashMap<String, String> subCategory = new HashMap<String, String>();
subCategory.put(Const.TAG_CATEGORY_ID, sub_id);
subCategory.put(Const.TAG_CATAEGORY_NAME,
sub_name);
subCategory.put(Const.TAG_THUMB_IMG,
thumb_image);
subCategory.put(Const.TAG_BIG_IMG, big_image);
subCategory.put(Const.TAG_OPTION_NAME,
option_name);
subCategory.put(Const.TAG_OPTION_VALUE,
option_value);
subCatList.add(subCategory);
}
}
