试试这个,
public JSONObject (Map copyFrom)
通过复制给定映射中的所有名称/值映射来创建一个新的 JSONObject.
Creates a new JSONObject by copying all name/value mappings from the given map.
参数copyFrom 一个映射,其键是 String 类型,其值是受支持的类型.
Parameters copyFrom a map whose keys are of type String and whose values are of supported types.
投掷如果地图的任何键为空,则为 NullPointerException.
Throws NullPointerException if any of the map's keys are null.
基本用法:
JSONObject obj=new JSONObject(yourmap);
从 JSONObject 中获取 json 数组
JSONArray array=new JSONArray(obj.toString());
(如果发现异常,则您可以更改为@krb686 在评论中提及的内容)
(If found Exception then You can change as mention in comment by @krb686)
JSONArray array=new JSONArray("["+obj.toString()+"]");
