Java 如何在Android中获得截击JSONArray

我是JSONArray排球队的新手。我无法在txtress中setText，因为我总是在onErrorResponse中遇到此错误

这是我的日志猫

…com.example.simplevolley.simplevolley W/System.err:org.json.JSONException:Value[{“com_branch_id”：7，“com_branch_commid”：1，“com_branch_name”：“JT Temerloh”，“com_branch_manager”：“Tn Hj Ahmad Bin Hj Mohd Sidin”，“com_branch addr”：“58号，Jalan Ibrahim（jl n Masjid Abu Bakar）”，“com_branch_region”：“Temerloh”，“com_branch_state”：“PAHANG”，“通信分公司国家”：“马来西亚”，“通信分公司邮政编码”：“28000”，“通信分公司电子邮件”：tmlh@juaratravel.com.my“，”com_branch_license“：null，“com_branch_phoneNum:”09-2965625“，”com_branch_fax“：null，“com_branch_fb”：null“，”com_branch_ig“：null}，{”com_branch id“：9，“com_branch_commid”：1，“com_branch_name:”JT Nibong Tebal“，”com_branch_经理“：”Pejabat Penang“，”通信分公司地址：“第10号，廷卡特Atas，Jln Pekaka 1，Tmn Pekaka”，“通信分公司地区”：“尼邦特巴尔”，“通信分公司州”：“槟榔屿”，“通信分公司国家”：“马来西亚”，“通信分公司邮政编码”：“14300”，“通信分公司电子邮件”：pen@juaratravel.com.my“，”com_branch_license“：null，“com_branch_phoneNum”：“05-7171877”，“com_branch_传真”：“057161877”，“com_branch_fb”“：null，“com\u branch\u ig”：null}

我想读这JSON行，但因为它是以JSONArray开头的，所以我很困惑

{
"res": true,
"datas": [
    {
        "com_branch_id": 7,
        "com_branch_comId": 1,
        "com_branch_name": "JT Temerloh",
        "com_branch_manager": "Tn Hj Ahmad Bin Hj Mohd Sidin",
        "com_branch_addr": "No.58, Jalan Ibrahim (Jln Masjid Abu Bakar)",
        "com_branch_region": "Temerloh",
        "com_branch_state": "PAHANG",

        "com_branch_licence": null,
        "com_branch_phoneNum": "09-2965625",
        "com_branch_fax": null,

    },
    {

        "com_branch_comId": 1,
        "com_branch_name": "JT Nibong Tebal",
        "com_branch_manager": "Pejabat Penang",
        "com_branch_addr": "No. 10, Tingkat Atas, Jln Pekaka 1, Tmn Pekaka,",
        "com_branch_region": "Nibong Tebal",
        "com_branch_state": "PULAU PINANG",
        "com_branch_country": "MALAYSIA",
        "com_branch_poscode": "14300",
        "com_branch_email": "pen@juaratravel.com.my",
        "com_branch_licence": null,
        "com_branch_phoneNum": "05-7171877",
        "com_branch_fax": "057161877",
        "com_branch_fb": null,
        "com_branch_ig": null
    },]}

我需要获取所有数据值。这是我的代码

 private void makeJsonArrayRequest() {
    showpDialog();

    JsonArrayRequest req = new JsonArrayRequest(urlJsonArry,
            new Response.Listener<JSONArray>() {
                @Override
                public void onResponse(JSONArray response) {
                    Log.d("res", response.toString());

                    try {


                        jsonResponse = "";
                        for (int i = 0; i < response.length(); i++) {


                            JSONObject branchi = (JSONObject) response.get(i);
                            JSONObject branch = branchi.getJSONObject("datas");


                            Integer com_branch_id = Integer.valueOf(branch.getString("com_branch_id"));
                            Integer com_branch_comId = Integer.valueOf(branch.getString("com_branch_comId"));

                            String com_branch_fax = branch.getString("datas.com_branch_fax");
                            String com_branch_fb = branch.getString("datas.com_branch_fb");
                            String com_branch_ig = branch.getString("datas.com_branch_ig");


                            jsonResponse = "";
                            jsonResponse += "Branch name: " + com_branch_id + "\n\n";

                        }

                        txtResponse.setText(jsonResponse);

                    } catch (JSONException e) {

@凌驾
公共void onResponse（JSONArray响应）{
Log.d（“res”，response.toString（））；
试一试{
jsonResponse=“”；
对于（int i=0；i

我试着跟随其他人

        public void onResponse(JSONObject response) {

            String message = "";
            if (response != null) {
                message = response.toString();
                Post post = null;
                Gson gson = new Gson();
                post = gson.fromJson(response.toString(), Post.class);

            } else {
                message = "Response is null";

            }
        }

 JSONObject json = new JSONObject(response);

    JSONArray jsonarray = json.getJSONArray("datas");

    for (int i = 0; i < jsonarray.length(); i++) {
         JSONObject c = jsonarray.getJSONObject(i);

         //here you get by json key
         String id = c.getString("com_branch_id");

    }
