      }
   ]
}

我不知道如何解析这个 json ？它有项目的总数。谢谢。

这应该让你开始，你需要继续你的定义......

JSONObject rootObject = new JSONObject(inputString);
int totalCount = rootObject.getInt("TotalCount");
JSONArray items = rootObject.getJSONArray("Items");

JSONObject item = null;
JSONObject itemDetails = null;
int productID = 0;
String subtitle = null;

for(int i = 0; i < items.size(); i++) {
    item = items.getJSONObject(i);
    productId = item.getInt()"ProductId");
    itemDetails = item.getJSONObject("Product");
    subtitle = itemDetails.getString("Subtitle");
}
