我通过JSONString
获得了以下HTTP Request
。我想要来自这个String的所有amount
值。
到目前为止我试过这个:
try {
// Getting JSON Array
JSONArray spritPriceArr = jObj.getJSONArray("spritPrice");
int spritPriceArrLength = spritPriceArr.length();
for(int i=0; i < spritPriceArrLength; i++ ){
JSONObject c = spritPriceArr.getJSONObject(i);
String amount = c.getString("amount");
System.out.println(amount);
}
} catch (JSONException e) {
e.printStackTrace();
}
这适用于第一个spritPrice Array
。但是,我怎样才能获得另一个amounts
的{{1}}?
我真的不知道如何实现这一目标。任何人都可以帮助我。
这是我的完整JSON字符串的链接:>>This<<

这样可行。
try{
JSONArray json = new JSONArray(str);
for(int i = 0; i< json.length();i++)
{
JSONObject c1 = (JSONObject) json.get(i);
JSONArray spritPrice = c1.getJSONArray("spritPrice");
for (int j = 0; j < spritPrice.length(); j++)
{
JSONObject c2 = (JSONObject) spritPrice.get(j);
String amount = c2.getString("amount");
System.out.println(amount);
}
}}catch (JSONException e){
e.printStackTrace();}

不仅仅是使用String,还可以使用ArrayList或List并添加每个价格。
像这样,
ArrayList<String> prices=new ArrayList<String>
在循环中写下面的代码。
String amount = c.getString("amount");
prices.add(amount);
您可以询问是否有任何进一步的疑问:)
答案 2 :(得分:0)
这是我从jsonarray获取字符串的方法,尝试这样做:
try {
JSONArray spritPriceArr = jObj.getJSONArray("spritPrice");
int spritPriceArrLength = spritPriceArr.length();
String[] StringofAmount = new Strng[spritPriceArrLength]
for(int i=0; i < spritPriceArrLength; i++ ){
JSONObject c = spritPriceArr.getJSONObject(i);
StringofAmount[i] = c.optString("amount");
}
} catch (JSONException e) {
e.printStackTrace();
}
答案 3 :(得分:0)
试试这个,
// ArrayList<String> amountList=new ArrayList<String>();
String amount=null;
try {
// Getting JSON Array
String your_json_response;
JSONArray responseArray = new JSONArray(your_json_response);
for(int j=0;j<responseArray.length();j++)
{
JSONArray spritPrice=responseArray.getJSONObject(i).JSONArray("spritPrice");
int spritPrice= spritPrice.length();
for(int i=0; i < spritPrice; i++ ){
JSONObject c = spritPrice.getJSONObject(i);
amount = c.getString("amount");
// amountList.add(amount);
System.out.println(amount);
if(amount!=null)
break;
}
if(amount!=null)
break;
}
} catch (JSONException e) {
e.printStackTrace();
}

这可能对你有帮助......
private ArrayList<String> arrayList = new ArrayList<String>();
public void loadAmountFrom(String jsonArrayString) {
try {
JSONArray jsonArray = new JSONArray(jsonArrayString);
loadAmountFromJsonArray(jsonArray);
} catch (Exception e) {
// TODO: handle exception
}
}
private void loadAmountFromJsonArray(JSONArray jsonArray) {
try {
for (int i = 0; i < jsonArray.length(); i++) {
Object object = jsonArray.get(i);
if (object instanceof JSONArray) {
loadAmountFromJsonArray(jsonArray);
} else if (object instanceof JSONObject) {
JSONObject jsonObject = (JSONObject) object;
loadAmount(jsonObject);
}
}
} catch (Exception e) {
// TODO: handle exception
}
}
private void loadAmount(JSONObject jsonObject) {
try {
Iterator<String> iterator = jsonObject.keys();
while(iterator.hasNext()) {
String key = (String) iterator.next();
if(key.equals("amount")) {
Object object = jsonObject.get(key);
arrayList.add(object.toString());
} else {
Object object = jsonObject.get(key);
if(object instanceof JSONArray) {
loadAmountFromJsonArray((JSONArray) object);
} else if(object instanceof JSONObject) {
loadAmount((JSONObject) object);
}
}
}
} catch (Exception e) {
// TODO: handle exception
}
}
只需将String响应传递给loadAmountFrom(String)方法......

您的数组spritPrice
长度为1:
"spritPrice":[
{
"amount":"1.329",
"datAnounce":"2013-11-27 13:05:07",
"errorItems":[
],
"errorCode":0,
"datValid":1385553907000,
"spritId":"DIE"
}
],
您的根元素必须是JSONArray
,而不是JSONObject
。
一个很好的链接:http://jsonformatter.curiousconcept.com/
它表明您的JSON是一个数组。
