Java 基础语法 Intent intent = new Intent(this,NoticeActivity.class); intent.putExtra

转json

ArrayList list = (ArrayList) JSON.parse(CommomDataManager.getAlipay_account());
        for (int i = 0;i < list.size();i++ ) {
            Map map = (Map) list.get(i);
            

        }

 

跳转取值

//上个界面跳转
 Intent intent = new Intent(this,NoticeActivity.class);
                    intent.putExtra("shouldRepayAmount",String.valueOf(info.totalRepayAmount));
                    startActivity(intent);



//下个界面取值
 shouldRepayAmount = getIntent().getStringExtra("shouldRepayAmount");

FastJson 转数组嵌套字典的字符串

JSONArray list = JSONObject.parseArray(CommomDataManager.getAlipay_account());
        for (int i = 0;i < list.size();i++ ) {
            Map map = (Map) list.get(i);
            map.get("name");
}
