Json解析之-実際開発中の特殊需要処理(手動解析-JSONObjectとJSONArrayで処理する)

どのJsonデータに対してもこの生の方法で解析できます.http://blog.csdn.net/jason_996/article/details/78039153)
使用(org.json.JSONArrayとorg.json.JSONObjectのバッグ):
1、{}に会ったら、JSONObjectで処理します.
2、[]が配列を表し、JSONArrayで処理されます.
以下はJsonデータです.

private String jsonString = "{\"Members\":{\"Owner\":{\"ID\":\"26\",\"LoginName\":\"gm1\",\"Name\":\"   A\",\"Email\":\"[email protected]\"},\"Host\":{\"ID\":\"29\",\"LoginName\":\"gm3\",\"Name\":\"   C\",\"Email\":\"\"},\"Recorder\":{\"ID\":\"26\",\"LoginName\":\"gm1\",\"Name\":\"   A\",\"Email\":\"[email protected]\"},\"Members\":[{\"ID\":\"26\",\"LoginName\":\"gm1\",\"Name\":\"   A\",\"Email\":\"[email protected]\"},{\"ID\":\"28\",\"LoginName\":\"gm2\",\"Name\":\"   B\",\"Email\":\"[email protected]\"},{\"ID\":\"29\",\"LoginName\":\"gm3\",\"Name\":\"   C\",\"Email\":\"\"}],\"Attendance\":[{\"ID\":\"29\",\"LoginName\":\"gm3\",\"Name\":\"   C\",\"Email\":\"\"}],\"Absence\":[{\"LoginName\":\"gm1\",\"Name\":\"   A\",\"Email\":\"[email protected]\"},{\"LoginName\":\"gm2\",\"Name\":\"   B\",\"Email\":\"[email protected]\"}]},\"Room\":{\"MeetingID\":\"6fa7eef5-6735-4fb1-a992-8088250be948\",\"MeetingRoomID\":\"2ebbe73b-bee4-4a9e-81c9-f8ffc6ca1149\",\"Address\":\"   -302   \",\"Date\":\"2017-09-14\",\"Text\":\"2017-09-14 14:00-15:00\",\"Value\":\"[14:00][14:30]\"},\"Attachments\":{\"Items\":[{\"Actor\":\"   A\",\"File\":\"1503808491.zip\",\"Url\":\"http://aaa.com/tory/MeetAttents/808491.zip\",\"Time\":\"2017-09-14 15:23\"}]},\"ID\":\"6fa7eef5-735-4f1-a992-8088250be948\",\"Type\":\"      \",\"Title\":\"   8888\",\"Address\":\"   -302   \",\"Time\":\"2017-09-14 14:00-15:00\",\"Note\":\"     \",\"Status\":\"   \",\"Author\":\"   A\",\"CreatedTime\":\"2017-09-14 14:48\",\"QrCode\":\"eyJ0eXBlIjozLCJpZCI6IjZmYThOTkyLTgwODgCx5YOP5ZyoODg4OCJ9\",\"Action\":\"[VIEW][RECORDER]\"}";
    

解析コード:(同じクラスではないものだけを解析して、残りの勉強中に完成します.)

private void parseJsonTwo() {
        String parseStringTwo = "  ：
";
        JSONObject jsonObject = null;
        try {
            jsonObject = new JSONObject(jsonString);
            //  
            String action = jsonObject.optString("Action");
            String id = jsonObject.optString("ID");
            String type = jsonObject.optString("Type");
            String title = jsonObject.optString("Title");
            String address = jsonObject.optString("Address");
            parseStringTwo += "Action:" + action + "
ID:" + id + "
Type:" + type + "
Title:" + title + "
Address:" + address + "
";
            //  ， Attachments  
            JSONObject attachments = jsonObject.getJSONObject("Attachments");
            JSONArray items = attachments.getJSONArray("Items");
            for (int i = 0; i < items.length(); i++) {
                JSONObject item = items.getJSONObject(i);
                String actor = item.optString("Actor");
                String file = item.optString("File");
                parseStringTwo += "Attachments--:
" + "Actor:" + actor + "
File:" + file + "
";
            }
            //  ， Members--Members  
            JSONObject membersObj = jsonObject.getJSONObject("Members");
            JSONArray membersArr = membersObj.getJSONArray("Members");
            for (int ii = 0; ii < membersArr.length(); ii++) {
                JSONObject membersItemObj = membersArr.getJSONObject(ii);
                String email = membersItemObj.optString("Email");
                String loginName = membersItemObj.optString("LoginName");
                String name = membersItemObj.optString("Name");
                parseStringTwo += "Members--Members:
" + "Email:" + email + "
LoginName:" + loginName + "
Name" + name + "
";
            }
        } catch (JSONException e) {
            e.printStackTrace();
        }
        tv.setText(parseStringTwo);
    }

出力結果:
