please give me some idea what to do and how to do

i guess, you should replace
msgList = MsgJSONParser.parseData(response);
MsgAdapter adapter = new MsgAdapter(ListMessage.this, msgList);
with
msgList = MsgJSONParser.parseData(response);
ArrayList<Msg_data> userList=new ArrayList();
for (int i=0;i<msgList.size();i++){
if (!userList.contains(msgList.get(i)))
userList.add(msgList.get(i));
else {
int index=userList.indexOf(msgList.get(i));
if (userList.get(index).compareTo(msgList.get(i))>0)
userList.add(msgList.get(i));
}
}
MsgAdapter adapter = new MsgAdapter(ListMessage.this, userList);`
and implement Comparable and override equals method in your Msg_data class
public class Msg_data implements Comparable {
public int id;
public String user_id;
public String user_name;
public String message;
public String is_read;
public String image_link;
public String created_at;
public String from;
public String to;
public String getFrom() {
return from;
}
public void setFrom(String from) {
this.from = from;
}
public String getTo() {
return to;
}
public void setTo(String to) {
this.to = to;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUser_id() {
return user_id;
}
public void setUser_id(String user_id) {
this.user_id = user_id;
}
public String getUser_name() {
return user_name;
}
public void setUser_name(String user_name) {
this.user_name = user_name;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public String getIs_read() {
return is_read;
}
public void setIs_read(String is_read) {
this.is_read = is_read;
}
public String getImage_link() {
return image_link;
}
public void setImage_link(String image_link) {
this.image_link = image_link;
}
public String getCreated_at() {
return created_at;
}
public void setCreated_at(String created_at) {
this.created_at = created_at;
}
public Msg_data() {
}
public Msg_data(int id) {
this.id = id;
}
#Override
public boolean equals(Object obj) {
try
{
return (this.getUser_id().equals(( (Msg_data)obj).getUser_id()));
}
catch(NullPointerException e){
return false;
}
}
#Override
public int compareTo(#NonNull Object o) {
SimpleDateFormat simpleDateFormat=new SimpleDateFormat("your pattern here");
try {
Date date=simpleDateFormat.parse(created_at);
Date dateOtherObject=simpleDateFormat.parse(((Msg_data)o).getCreated_at());
return date.compareTo(dateOtherObject);
}
catch (ParseException e){
return -1;
}
}
something like this:) Dont forget replace simple date format in compare method

Recyclerview sort by time ascending

I have a recyclerview that display news.
News is composed by name_news,image_news,time_news.
I am getting the data from mysqldatabse.
This is my adapter class:
public class PostAdapter2 extends RecyclerView.Adapter<PostAdapter2.ViewHolder>{
public Context c;
public FragmentManager mContext;
public ArrayList<News_data> original_items = new ArrayList<>();
public ArrayList<News_data> filtered_items = new ArrayList<>();

this.original_items = postList;
this.filtered_items = postList;
}
public PostAdapter2(FragmentManager mContext, ArrayList<Simplenews_data> postList) {

this.original_items2 = postList;
this.filtered_items2 = postList;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

}
#Override
public void onBindViewHolder(ViewHolder holder, final int position) {

}
I am using a PHP interface to add news.
The getTime_simplenews() contains the news sumbmitted time format as : 14:00
So i want to display the immediate news in Top of recyclerview not under the previous news.
Thanks a lot.
UPDATED :
public class Simplenews_data {
int id_simplenews;
String name_simplenews,image_simplenews,desc_simplenews,time_simplenews,date_simplenews;
public String getDate_simplenews() {

}
public void setDate_simplenews(String date_simplenews) {
this.date_simplenews = date_simplenews;
}
public String getTime_simplenews() {
return time_simplenews;
}
public void setTime_simplenews(String time_simplenews) {
this.time_simplenews = time_simplenews;
}
public int getId_simplenews() {
return id_simplenews;
}
public void setId_simplenews(int id_simplenews) {
this.id_simplenews = id_simplenews;
}
public String getName_simplenews() {
return name_simplenews;
}
public void setName_simplenews(String name_simplenews) {
this.name_simplenews = name_simplenews;
}
public String getImage_simplenews() {
return image_simplenews;
}
public void setImage_simplenews(String image_simplenews) {
this.image_simplenews = image_simplenews;
}
public String getDesc_simplenews() {
return desc_simplenews;
}
public void setDesc_simplenews(String desc_simplenews) {
this.desc_simplenews = desc_simplenews;
}
Fragment Code:
public void parseJson2(String response) {
try {
JSONArray array = new JSONArray(response);
JSONObject jsonObject = null;
post_array2.clear();
Simplenews_data p;
for (int i = 0; i < array.length(); i++) {

int id_simplenews = jsonObject.getInt("id_simplenews");
String name_simplenews = jsonObject.getString("name_simplenews");

I have updated your model class and implemented Comparable to it
public class Simplenews_data implements Comparable<Simplenews_data> {
int id_simplenews;
String name_simplenews,image_simplenews,desc_simplenews,time_simplenews,date_simplenews;
public String getDate_simplenews() {

}
public void setDate_simplenews(String date_simplenews) {
this.date_simplenews = date_simplenews;
}
public String getTime_simplenews() {
return time_simplenews;
}
public void setTime_simplenews(String time_simplenews) {
this.time_simplenews = time_simplenews;
}
public int getId_simplenews() {
return id_simplenews;
}
public void setId_simplenews(int id_simplenews) {
this.id_simplenews = id_simplenews;
}
public String getName_simplenews() {
return name_simplenews;
}
public void setName_simplenews(String name_simplenews) {
this.name_simplenews = name_simplenews;
}
public String getImage_simplenews() {
return image_simplenews;
}
public void setImage_simplenews(String image_simplenews) {
this.image_simplenews = image_simplenews;
}
public String getDesc_simplenews() {
return desc_simplenews;
}
public void setDesc_simplenews(String desc_simplenews) {
this.desc_simplenews = desc_simplenews;
}
#Override
public int compareTo(MyObject o) {
Date newDate = formatDateTime(o.getTime_simplenews(), "HH:mm", "YYYY-MM-DD HH:mm");
Date inputDate = formatDateTime(getTime_simplenews(), "HH:mm", "YYYY-MM-DD HH:mm");
return inputDate.compareTo(newDate);
}
public Date formatDateTime(String date, String fromFormat, String toFormat) {
Date d = null;
try {
d = new SimpleDateFormat(fromFormat, Locale.US).parse(date);
} catch (ParseException e) {
e.printStackTrace();
}
return new SimpleDateFormat(toFormat, Locale.US).parse(d);
}
}
Sort the list using below code
Collections.sort(yourList);

Struggling to get data from a rss file into an array list in android

I am creating a app that requires information that is in an rss file (will eventually be an actual feed but it doesn't exist yet) to be put into a recycler view, with each separate card showing only a snippet of information and when the user clicks onto the card it opens into another activity to show all the info. However I am not sure how to access the local file as I would an actual live feed. Any help would be much appreciated.
My rss file is in xml format and called dummy_RSS.rss.
I have a class to specify the the strings needed
public class EventViewDetails {
private String title;
private String location;
private String locLat;
private String locLong;
private String date;
private String timeStart;
private String timeFinish;
private String desc;
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getLocation() {

}
public void setLocation(String location) {

}
public String getLocLat() {

}
public void setTimeStart(String timeStart) {
this.timeStart = timeStart;
}
public String getTimeFinish() {

this.timeFinish = timeFinish;
}
public String getDesc() {
return desc;
}
public void setDesc(String desc) {
this.desc = desc;

}
I have a class to parse the data from the feed into the above strings
public class ParseEventDetails {

private ArrayList<EventViewDetails> events;
public ParseEventDetails(String xmlData) {
data = xmlData;
events = new ArrayList<EventViewDetails>();

int type = xpp.getEventType();
while (type != XmlPullParser.END_DOCUMENT) {
String tagName = xpp.getName();
if (type == XmlPullParser.START_TAG) {

I have the adapter for the recycler view
public class EventCalenderAdapter extends RecyclerView.Adapter<EventCalenderAdapter.ViewHolder> {

CardView cardView;
TextView titleView;
public ViewHolder(CardView card) {
super(card);
cardView = card;
titleView = (TextView) card.findViewById(R.id.text1);
}
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int i) {
CardView v = (CardView) LayoutInflater.from(parent.getContext()).inflate(R.layout.event_task, parent, false);
return new ViewHolder(v);
}
#Override
public void onBindViewHolder(ViewHolder viewHolder, final int i) {
final Context context = viewHolder.titleView.getContext();
viewHolder.titleView.setText(xmlData[i]);
viewHolder.cardView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
((OnEventView) context).eventView(i);
}
});
}
#Override
public int getItemCount() {
return xmlData.length;
}
}
and I have my fragment
public class EventCalenderFragment extends Fragment {
RecyclerView recyclerView;
EventCalenderAdapter adapter;
public EventCalenderFragment() {
// Required empty public constructor
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
adapter = new EventCalenderAdapter();
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
final View v = inflater.inflate(R.layout.fragment_event_calender, container, false);
recyclerView = (RecyclerView) v.findViewById(R.id.recycler);
recyclerView.setAdapter(adapter);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
return v;
}
}
As I have said I'm not sure how to access the local file or where to put the initial access.

you must change access configuration in your phpmyadmin configuration to "allow any" and then the url will be something like that : localhost/your_php_project_name/your_php_file
note that the file your_php_file must return xml data or file

I want to pass hashmap from custom arrayadapter to activity?

I want to pass HashMap or ArrayList Object from Custom ArrayAdapter to activity which fills the ListView.I want to send checked records recordId field.I m new To Android.Any Suggestion Plz

Pass the adapter a reference to the activity. Then provide a method in the activity that the adapter can call.
In adapter:
private MyActivity activity;
public void setActivity(MyActivity activity) {
this.activity = activity;
}
In Activity:
// create adapter
adapter.setActvity(this);
In adapter (when you want to pass parameters back to activity):
activity.setHashMap(mymap);

My CustomAdapter Class::
class SearchResultAdapter extends ArrayAdapter{
Context context;
int layoutResourceId;
private ArrayList<SearchResultModel> results;
public SearchResultAdapter(Context context, int layoutResourceId, ArrayList<SearchResultModel> results) {
super(context, layoutResourceId, results);
this.layoutResourceId = layoutResourceId;
this.context = context;
this.results = results;
}
#Override
public View getView(int position, View convertView, ViewGroup parent)
{
View row = convertView;
SearchResultHolder holder=null;
if(row == null)
{

row = vi.inflate(R.layout.listitemrow, null);
holder = new SearchResultHolder();
holder.jobdetails = (TextView)row.findViewById(R.id.jobdetails);
row.setTag(holder);
}
else
{
holder = (SearchResultHolder)row.getTag();
}
SearchResultModel model = results.get(position);
if (model != null)
{
row.setId(Integer.parseInt(model.getjob_id()));
String result=
"<font color=#5D2E8C>"+model.getjob_title()+"</font><br>" +
"<font color=#737373>"+model.getpost_date()+"</font><br>"+model.getuser_name()+"<br>" +
"<font color=#3C5A98>"+model.getsalary()+" Rs (Per Annum)</font><br>"+
