                    String value = jsonArray.get(j).toString();
                    idList.add(value);
                }
                //关联id
                map.put("list", idList);
            });
            map.put("withRole",withRole);

 

java string转换数组

java文件转json字符串数组中 java json转成数组_i++

import org.json.JSONArray;
JSONArray param;
param = new JSONArray(withRole);
            String[] withRoleArr = new String[param.length()];
            //关联模板的id集合
            for (int i = 0; i < withRoleArr.length; i++) {
                withRoleArr[i] = param.get(i).toString();
                withRoleList.add(withRoleArr[i]);
            }
