问题在于API未被命中的条件总是位于其他条件。我无法获得成功的数据。我说对了
数组中的数据，但API可能无法获取数组的字符串值
我正在遇到其他情况。
请帮我解决这个问题，我认为问题出在参数
{ JSONObject jo = new JSONObject();
try {
Collection<JSONObject> items = new ArrayList<JSONObject>();
for (int i = 0; i < 1; i++) {
JSONObject item1 = new JSONObject();
item1.put("product_id", product_id);
if ("1".equals(getIntent().getStringExtra("catId"))) {
Log.d("Marked", "marked");
item1.put("quantity", String.valueOf(quant));
item1.put("cardId", String.valueOf(cardId));
} else {
item1.put("quantity", countText.getText().toString());
item1.put("cardId", String.valueOf(50));
Log.d("poker", "poker");
}
item1.put("price", money.getText().toString());
items.add(item1);
}
jo.put("cart_data", new JSONArray(items));
Log.d("jsonmaidata", new JSONArray(items).toString());
System.out.println(jo.toString());
} catch (Exception e) {
e.printStackTrace();
}
Log.d("checkJO", String.valueOf(jo));
Log.d("mobile", session.getUserDetails().get(SessionManagement.KEY_MOBILE));
add_cart(String.valueOf(jo), new CallBack() {

这2种方法将帮助您将jsonarray转换为String并将字符串转换回jsonArray
public static String jsonArrToString(JsonArray arr) {
Gson gson = new Gson();
Type type = new TypeToken<JsonArray>() {
}.getType();
String json = gson.toJson(arr, type);
return json;
}
public static String[] stringToJsonArray(String json) {
Gson gson = new Gson();
Type type = new TypeToken<String[]>() {
}.getType();
JsonArray arr = gson.fromJson(json, type);
return arr;
}
