推荐答案
将您的jsonobect更改为sl_summ，例如
Change your jsonobect for sl_summ like this
JsonObject json = new JsonObject(response);
if(json.has("sl_summ"){
JSONObject sl_jObj = new JSONObject(json.getString("sl_summ"));
}
这篇关于Json错误:java.lang.String类型的值sl_summ无法转换为JSON OBJECT的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
