使用 GsonFormat 解析数组形式的 json 作者: Chuwen 时间: 2020-10-12 分类: Android,Java 评论 > 记下笔记，以访忘记 # 假设有以下数据 ``` [{ "CarId": 1, "Time": "2017-11-26 16:58:11", "Cost": 10 }, { "CarId": 1, "Time": "2017-11-26 16:58:19", "Cost": 20 }, { "CarId": 1, "Time": "2017-11-26 16:58:24", "Cost": 30 }, { "CarId": 1, "Time": "2017-11-26 16:58:28", "Cost": 40 }] ``` # 以下类 ``` public class GetCarAccountRecord { /** * CarId : 1 * Time : 2017-11-26 04:58:11 * Cost : 10 */ private int CarId; private String Time; private int Cost; public int getCarId() { return CarId; } public void setCarId(int CarId) { this.CarId = CarId; } public String getTime() { return Time; } public void setTime(String Time) { this.Time = Time; } public int getCost() { return Cost; } public void setCost(int Cost) { this.Cost = Cost; } } ``` # 使用 Gson 解析，然后遍历输出 ``` List<GetCarAccountRecord> list = new Gson().fromJson(jsonObject.optJSONArray("ROWS_DETAIL").toString(), new TypeToken<List<GetCarAccountRecord>>() {}.getType()); for (GetCarAccountRecord getCarAccountRecord : list) { Log.i("小车编号：", String.valueOf(getCarAccountRecord.getCarId())); Log.i("充值金额：", String.valueOf(getCarAccountRecord.getCost())); } ```
Android 使用 OkHttp 进行网络请求之 POST json数据 作者: Chuwen 时间: 2020-07-12 分类: Android 评论 # 相关代码 > 只是避免遗忘，然后记录下的，具体还是要自己去搜索 ``` OkHttpClient okHttpClient = new OkHttpClient(); //指定媒体类型 MediaType mediaType = MediaType.parse("application/json"); RequestBody requestBody = RequestBody.create(mediaType, json); Request request = new Request.Builder() .url(url) .post(requestBody) .build(); okHttpClient.newCall(request).enqueue(new Callback() { @Override public void onResponse(Call call, Response response) throws IOException { SetSuggesRes = response.body().string(); Log.d("请求成功", SetSuggesRes); /** * 在Ui线程更新UI */ runOnUiThread(new Runnable() { @Override public void run() { requestDialog.hide();//隐藏那个加载对话框 try { JSONObject resObj = new JSONObject(SetSuggesRes); if (resObj.getString("RESULT").equals("S")) { showNormalDialog("意见反馈", "意见反馈成功！", 1); } else { showNormalDialog("意见反馈", "意见反馈失败，原因：" + resObj.getString("ERRMSG").toString(), 2); } } catch (JSONException e) { e.printStackTrace(); showNormalDialog("意见反馈", "意见反馈失败，原因(远程服务器返回内容不符合预期)：\n" + e.getMessage().toString(), 2); } } }); } @Override public void onFailure(Call call, final IOException e) { Log.d("请求失败", e.getMessage().toString()); runOnUiThread(new Runnable() { @Override public void run() { requestDialog.hide(); showNormalDialog("意见反馈", "意见反馈失败了，原因：\n" + e.getMessage(), 2); } }); } }); ```
