我在字符串变量中有Json对象。

有人可以告诉我如何在价格中访问“price_currency”吗？

 JSONObject json = new JSONObject(output);
           String sc = json.get("styles").toString();

我使用上面的方法获得了样式，

之后我使用下面的代码获得了样式。风格在风格内。

JSONObject json1 = new JSONObject(sc);
               String sc1 = json1.get("style").toString();

现在我想在价格中获得“price_currency”？我该怎么做？

Answer 1

您的价格在array范围内。您必须先通过索引

访问数组中的元素

JSONObject outputJson = new JSONObject(output);
JSONObject style = outputJson.getJsonObject("styles").getJsonArray("style").getJsonObject(0);
JSONObject price = style.getJsonArray("prices").getJsonObject(0);
String currency = price.getString("price_currency");

修改

JSONArray实施List<JSONObject>，您可以这样做：

for (JSONObject price : style.getJsonArray("prices")) { String currency = price.getString("price_currency"); }

从java中的Json Object获取值
