如何从JSON数据解析日期和时间并设置提醒

Question

我有一个包含日期和时间信息的JSON对象，我想检索数据并根据日期/时间设置提醒。

{ “状态”：200， “消息”： “成功”， “结果”：[{ “Remainderid”： “1” “余数”： “生日”， “日期”：“2017-06 -13 10:00:00" }]}

而且我的代码

private void getReminder() { 
    String url = Urls.current_date_view + "&Userid=" + Model.getInstance().userid;// Model.getInstance().userid; 
    Log.e("RemindersUrl====>", "" + url); 
    AsyncHttpClient client = new AsyncHttpClient(); 
    client.get(getApplicationContext(), url, new AsyncHttpResponseHandler() { 
     @Override 
     public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) { 
      reminsList = new ArrayList<HashMap<String, String>>(); 
      reminsList.clear(); 
      try { 
       reminresponse = new JSONObject(new String(responseBody)); 
       if (reminresponse == null) { 
        Toast.makeText(getApplicationContext(), "Please Check Internet Connection", Toast.LENGTH_SHORT).show(); 
       } else { 
        /*{"status":200,"message":"Success","result":[{,"Remainderid":"1" 
         "Remainder":"Birthday","Date":"2017-06-13 10:00:00"}]}*/ 
        remind_status = reminresponse.optString("status"); 
        reminstatus_msg = reminresponse.optString("message"); 
        if (remind_status.equalsIgnoreCase("200")) { 
         JSONArray array = reminresponse.getJSONArray("result"); 
         for (int i = 0; i < array.length(); i++) { 
          JSONObject object = array.getJSONObject(i); 
          String mTime = "", mDate = ""; 
          String mIDs = object.getString("Remainderid"); 
          String mTitle = object.getString("Remainder"); 
          String curDate = object.getString("Date"); 


          Calendar calendars = Calendar.getInstance(); 
          Log.e("DATEANDmIDs====>", " " + mIDs + " "); 

          SimpleDateFormat f = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss"); 
          java.util.Date datemniles = f.parse(curDate); 
          calendars.setTime(datemniles); 
          mHour = calendars.get(Calendar.HOUR_OF_DAY); 
          mMinute = calendars.get(Calendar.MINUTE); 
          mYear = calendars.get(Calendar.YEAR); 
          mMonth = calendars.get(Calendar.MONTH); 
          mDay = calendars.get(Calendar.DATE); 

          mDate = mDay + "-" + mMonth + "-" + mYear; 
          mTime = mHour + ":" + mMinute; 

          mCalendar.set(Calendar.MONTH, mMonth); 
          mCalendar.set(Calendar.YEAR, mYear); 
          mCalendar.set(Calendar.DAY_OF_MONTH, mDay); 
          mCalendar.set(Calendar.HOUR_OF_DAY, mHour); 
          mCalendar.set(Calendar.MINUTE, mMinute); 
          mCalendar.set(Calendar.SECOND, mSec); 
          saveReminder(mIDs, mTitle, mTime, mDate); 

         } 
        } 
       } 
      } catch (JSONException e) { 
       e.printStackTrace(); 
      } catch (ParseException e) { 
       e.printStackTrace(); 
      } 
     } 

     @Override 
     public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) { 

     } 
    }); 
} 

SetRemainder代码

public void saveReminder(String mIDs, String mTitle, String mTime, String mDate) { 

    Intent intents=getIntent(); 
    int ID; 
    String reminder=""; 

    // Check repeat type 
    reminders = rb.getAllReminders(); 
    Log.e("remindersALL===>", "" + reminders); 
    if (reminders.isEmpty()) { 
    //AddSqliteDataBase 
     ID = rb.addReminder(new Reminder_set(Integer.parseInt(mIDs), mTitle, mDate, mTime)); 
     getAlarams(ID); 
    } else if (!reminders.isEmpty()) { 
     for (int i = 0; i < reminders.size(); i++) { 
      reminder = String.valueOf(reminders.get(i).getID()); 
     } 
     if (reminder.equalsIgnoreCase(mIDs+1)) { 
      Log.e("WorkEquals===>", "" + reminder); 
      getUpdates(String.valueOf(Integer.parseInt(mIDs)), mTitle, mDate, mTime); 
     } else { 
      ID = rb.addReminder(new Reminder_set(Integer.parseInt(mIDs), mTitle, mDate, mTime)); 
      Log.e("NotEqualsID===>", "" + reminder+"==="+mIDs+1); 
      getAlarams(ID); 
     } 


    } 
} 

private void getAlarams(int ID) { 
    Log.e("Alaram==>",""+"Workesd ==>" +ID); 
    new AlarmReceiver().setAlarm(getApplicationContext(), mCalendar, ID); 

} 

private void getUpdates(String mIDs, String mTitle, String mTime, String mDate) { 
    mReceivedReminder = rb.getReminder(Integer.parseInt(mIDs)); 
    mReceivedReminder.setID(Integer.parseInt(mIDs)); 
    mReceivedReminder.setTitle(mTitle); 
    mReceivedReminder.setDate(mDate); 
    mReceivedReminder.setTime(mTime); 
    rb.updateReminder(mReceivedReminder); 
} 

Answer 1

试试这个

创建一个JSON对象

JSONObject data = getJSONObject(response); 

为了得到一个特定的字符串

String date = data.getString("Remindercurdate"); 
String Reminder = data.getString("Reminder"); 

现在转换字符串中的日期这样

String mydate = date;// your date from json 
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'"); 
try { 
    Date Resultdate = format.parse(mydate); 
    Log.e("Date id ",""+Resultdate); 
    } catch (ParseException e) { 

    e.printStackTrace(); 
}
