I have a JSONObject and an ArrayList from where i get the data, the data date string i get is yyyy/MM/dd 00:00:00, i only want to show the day of the month 1-31, how would i format that string to only show the day ?
I've tried to use SimpleDateFormat, but without any luck, maybe since I'm doing this inside a for loop ?
public void onResponse(String response) {
try {
//getting the whole json object from the response
JSONObject obj = new JSONObject(response);
ArrayList<ListModel> ListModelArrayList = new ArrayList<>();
JSONArray dataArray = obj.getJSONArray("events");
for (int i = 0; i < dataArray.length(); i++) {
ListModel List = new ListModel();
JSONObject dataobj = dataArray.getJSONObject(i);
List.setId(dataobj.getString("id"));
List.setInit_date(dataobj.getString("init_date"));
List.setEnd_date(dataobj.getString("end_date"));
List.setTitle(dataobj.getString("title"));
List.setDescription(dataobj.getString("description"));
List.setColor_code(dataobj.getString("color_code"));
List.setAll_day(dataobj.getString("all_day"));
ListModelArrayList.add(List);
}
for (int j = 0; j < ListModelArrayList.size(); j++) {
textViewDate.setText(textViewDate.getText() +
ListModelArrayList.get(j).getInit_Date() + "\n");
textViewEvent.setText(textViewEvent.getText() +
ListModelArrayList.get(j).getTitle() + "\n");
}
right now i am getting this format 2019-05-17 00:00:00, i want to display 17 only
You can alter SimpleDateFormat as you suggested and instead of putting the date directly in the for loop here :
textViewDate.setText(textViewDate.getText() +
ListModelArrayList.get(j).getInit_Date() + "\n");
You will do the following inside your loop :
String s = ListModelArrayList.get(j).getInit_Date();
SimpleDateFormat fmt = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss", Locale.ENGLISH);
Date date = null;
try {
date = fmt.parse(s);
SimpleDateFormat fmtOut = new SimpleDateFormat("dd", Locale.ENGLISH);
textViewDate.setText(textViewDate.getText() +
fmtOut.format(date) + "\n");
} catch (ParseException e) {
textViewDate.setText(textViewDate.getText() + "\n");
e.printStackTrace();
}
Which allows you to format the date according to the pattern you wish in this line :
SimpleDateFormat fmtOut = new SimpleDateFormat("dd", Locale.ENGLISH);
