我有以下响应...从这个响应中我正在解析bulkprice数组及其对象，现在我正在尝试的是我需要将所有minqty值存储在一个数组列表中并希望将所有这些值转换为Integer..但是我无法理解..
{"status":"success","clientproduct":[{"pid":"4","name":"kangan pair","unitprice":"1500","boxqty":"1","bulkprice":[{"minqty":"10","price":"1500"},{"minqty":"15","price":"1470"},{"minqty":"20","price":"1460"}]}]}

试试这个：
ArrayList<Integer> minqtyList = new ArrayList<Integer>();
JSONArray array = ck.getJSONArray(BULKPRICE_LIST);
for (int i = 0; i < array.length(); i++) {
JSONObject row = array.getJSONObject(i);
int minqty = row.getInt("minqty");
minqtyList.add(minqty);
}
在您的代码中，您需要像这样编辑这部分：
bulkprice = ck.getJSONArray(BULKPRICE_LIST);
allqtys=new ArrayList<String>(); // initialisation must be outside the loop
for (int b=0 ; b < bulkprice.length(); b++){
jo = bulkprice.getJSONObject(b);
minimum_qty=jo.getString("minqty");
allqtys.add(minimum_qty);
System.out.println("All MinQuantitiy"+minimum_qty);
System.out.println("MinQuantitiy"+minimum_qty);
pricess=jo.getString("price");// here you'll get only the last value. otherwise you need to use a list, like you did with "minqty"
System.out.println("Box price "+pricess);
}
我建议您使用 JSONArray 来存储 json 值并迭代它们：
String strJSON = ""; // your string goes here
List<int> minqtys = new ArrayList<int>();
JsonReader rdr = Json.createReader(new StringReader(strJSON)) {
JsonObject obj = rdr.readObject();
JsonArray results = obj.getJsonArray("bulkprice");
for (JsonObject result : results.getValuesAs(JsonObject.class)) {
int minqty = Integer.parseInt(result.getString("minqty"));
minqtys.add(minqty);
}
});
您可以通过使用Gson轻松实现这一点。
示例：
List<CustomObject> myList = gson.fromJson(br, new
TypeToken<List<CustomObject>>(){}.getType());
使用此代码..
String json="{\"status\":\"success\",\"clientproduct\":[{\"pid\":\"4\",\"name\":\"kangan pair\",\"unitprice\":\"1500\",\"boxqty\":\"1\",\"bulkprice\":[{\"minqty\":\"10\",\"price\":\"1500\"},{\"minqty\":\"15\",\"price\":\"1470\"},{\"minqty\":\"20\",\"price\":\"1460\"}]}]}";
String json1="{\"status\":\"success\",\"clientproduct\":[{\"pid\":\"4\",\"name\":\"kangan pair\",\"unitprice\":\"1500\",\"boxqty\":\"1\",\"bulkprice\":[{\"minqty\":\"10\",\"price\":\"1500\"},{\"minqty\":\"15\",\"price\":\"1470\"},{\"minqty\":\"20\",\"price\":\"1460\"}]},{\"pid\":\"6\",\"name\":\"Mala\",\"unitprice\":\"1500\",\"boxqty\":\"1\",\"bulkprice\":\"\"}]}";
JSONObject jsonobj;
List<HashMap<String,String>> minqty_list=new ArrayList<HashMap<String,String>>();
try {
jsonobj = new JSONObject(json1);
JSONArray client_product=jsonobj.getJSONArray("clientproduct");
for(int i=0;i<client_product.length();i++)
{
JSONObject client_prod=client_product.getJSONObject(i);
try
{
JSONArray bulkprice=client_prod.getJSONArray("bulkprice");
for(int j=0;j<bulkprice.length();j++)
{
HashMap<String, String> hs=new HashMap<String, String>();
hs.put("bulk",bulkprice.getJSONObject(j).getString("minqty"));
minqty_list.add(hs);
}
}catch(JSONException e)
{
e.printStackTrace();
}
}
System.out.println(minqty_list.toString());
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
在上面的代码中将其更改为
JSONArray bulkprice=client_prod.getJSONArray("bulkprice");
for(int j=0;j<bulkprice.length();j++)
{
minqty_list.add(Integer.parseInt(bulkprice.getJSONObject(j).getString("minqty")));
}
到此
try
{
JSONArray bulkprice=client_prod.getJSONArray("bulkprice");
for(int j=0;j<bulkprice.length();j++)
{
HashMap<String, String> hs=new HashMap<String, String>();
hs.put("bulk",bulkprice.getJSONObject(j).getString("minqty"));
minqty_list.add(hs);
}
}catch(JSONException e)
{
e.printStackTrace();
}
有趣的 loadFontsFromJson(context: Context): ArrayList { val 字体列表 = ArrayList() val json: 字符串 尝试 { val inputStream = context.assets.open("font_list.json") val 大小 = inputStream.available() val 缓冲区 = ByteArray(大小) 输入流.read(缓冲区) 输入流.close() json = kotlin.String() val jsonObject = JSONObject(json) val fontArray = jsonObject.getJSONArray("fontList") for (i in 0 直到 fontArray.length()) { val 字体 = fontArray.getString(i) 字体列表.add(字体) } } catch (e: IOException) { e.printStackTrace() } catch (e: JSONException) { e.printStackTrace() } 返回字体列表 }
