我找不出爲什麼我的json解析不起作用。這裏是我正在使用的Api。另外的鏈接完整JSON輸出http://api.openweathermap.org/data/2.5/forecast/daily?zip=85008&amode=json&units=metric&cnt=7&APPID=3c6fee6e3e8b5764212701d9535a36d5無法正確解析Json使用翻新

我想從每天的最小和最大的臨時工。這是我的代碼。拋出的異常是期望的BEGIN_OBJECT,但在第1行第190列有NUMBER。任何幫助表示感謝,謝謝!

可以請您分享一下WeatherAPI嗎? – VVB
我認爲把temp當做散列表示在list1類中是不對的,它應該是一個單獨的對象'Temps temp;',因爲在json中它是每個列表項的1個'temp' – Yazan
就是這樣!謝謝雅贊 –
