I am trying to make a Chat bubble and I need to insert the timestamps in each bubble, I have my adapter to insert the messages but I do not know how to add the timestamps, someone could tell me how to do it.
Here the MainActivity code:
public class MainActivity extends AppCompatActivity {
private ListView listView;
private View btnSend;
private EditText editText;
boolean myMessage = true;
private List<ChatBubble> ChatBubbles;
private ArrayAdapter<ChatBubble> adapter;
private TextView dateTimeTx;
private TextView dateTimeRx;
private String dateTime;
private String timestamp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ChatBubbles = new ArrayList<>();
listView = (ListView) findViewById(R.id.list_msg);
btnSend = findViewById(R.id.btn_chat_send);
editText = (EditText) findViewById(R.id.msg_type);
//set ListView adapter first
adapter = new MessageAdapter(this, R.layout.tx_chat_bubble, ChatBubbles);
listView.setAdapter(adapter);
//event for button SEND
btnSend.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (editText.getText().toString().trim().equals("")) {
Toast.makeText(MainActivity.this, "Please input some text...", Toast.LENGTH_SHORT).show();
} else {
//add message to list
ChatBubble ChatBubble = new ChatBubble(editText.getText().toString(), myMessage, timestamp.toString() );
ChatBubbles.add(ChatBubble);
adapter.notifyDataSetChanged();
editText.setText("");
if (myMessage) {
myMessage = false;
} else {
myMessage = true;
}
}
}
});
}
}
But I have a error in :
ChatBubble ChatBubble = new ChatBubble(editText.getText().toString(), myMessage, timestamp.toString() );
Here mi Adapter code:
public class MessageAdapter extends ArrayAdapter<ChatBubble> {
private Activity activity;
private List<ChatBubble> messages;
private String dateTime;
private SimpleDateFormat simpleDateFormat ;
public MessageAdapter(Activity context, int resource, List<ChatBubble> objects) {
super(context, resource, objects);
this.activity = context;
this.messages = objects;
String isoDatePattern = "dd/MM/yyyy HH:mm";
simpleDateFormat = new SimpleDateFormat(isoDatePattern);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
LayoutInflater inflater = (LayoutInflater) activity.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
int layoutResource = 0; // determined by view type
ChatBubble ChatBubble = getItem(position);
int viewType = getItemViewType(position);
if (ChatBubble.myMessage()) {
layoutResource = R.layout.tx_chat_bubble;
} else {
layoutResource = R.layout.rx_chat_bubble;
}
if (convertView != null) {
holder = (ViewHolder) convertView.getTag();
} else {
convertView = inflater.inflate(layoutResource, parent, false);
holder = new ViewHolder(convertView);
convertView.setTag(holder);
}
//set message content
holder.msg.setText(ChatBubble.getContent());
holder.dateTimeTx.setText(ChatBubble.getTimestamp());
return convertView;
}
#Override
public int getViewTypeCount() {
return 2;
}
#Override
public int getItemViewType(int position) {
return position % 2;
}
private class ViewHolder {
private TextView msg;
private TextView dateTimeTx;
public ViewHolder(View v) {
msg = (TextView) v.findViewById(R.id.txt_msg);
dateTimeTx = (TextView) v.findViewById(R.id.time_msg);
}
}
private String readFechaActual(long timestamp){
return simpleDateFormat.format(new Date(timestamp));
}
}
But I have another error in:
holder.dateTimeTx.setText(ChatBubble.getTimestamp());
Here is the ChatBubble class:
public class ChatBubble {
private String content;
private boolean myMessage;
private long timestamp;
public ChatBubble(String content, boolean myMessage, long timestamp) {
this.content = content;
this.myMessage = myMessage;
this.timestamp = timestamp;
}
public String getContent() {
return content;
}
public boolean myMessage() {
return myMessage;
}
public long getTimestamp() {
return timestamp;
}
}
Create single (to avoid unused resource requirements) SimpleDateFormat in an adapter constructor:
private SimpleDateFormat simpleDateFormat ;
public MessageAdapter(Activity context, int resource, List<ChatBubble> objects) {
super(context, resource, objects);
this.activity = context;
this.messages = objects;
String isoDatePattern = "dd/MM/yyyy HH:mm";
simpleDateFormat = new SimpleDateFormat(isoDatePattern);
}
Update the helper method to return formatted date string:
private String readFechaActual(long timestamp){
return simpleDateFormat.format(new Date(timestamp));
}
}
Use it in getView:
//set message content
holder.msg.setText(ChatBubble.getContent());
holder.dateTimeTx.setText("" + ChatBubble.getTimestamp()); // <--- ADD HERE
The adapter only connects View and Model, but actual data keeps in model, so you should change the BubbleChat class and add timestamp field:
public class ChatBubble {
private String content;
private boolean myMessage;
private long timestamp;
public ChatBubble(String content, boolean myMessage, long timestamp) {
this.content = content;
this.myMessage = myMessage;
this.timestamp = timestamp;
}
public String getContent() {
return content;
}
public boolean myMessage() {
return myMessage;
}
public long getTimestamp() {
return timestamp;
}
}
You should set the time in getView, same way you set the bubble's message.
You already have the field in the ViewHolder.
Also, ChatBubble ChatBubble = getItem(position); should be ChatBubble chatBubble = getItem(position);
And please use RecyclerView
Create a model

return nowDate;
}
public static Date newDate(String timeStamp){
Date OurDate = null;
try{
SimpleDateFormat formatter = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
formatter.setTimeZone(TimeZone.getTimeZone("UTC"));
Date value = formatter.parse(timeStamp);
SimpleDateFormat dateFormatter = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
dateFormatter.setTimeZone(TimeZone.getDefault());
String n = dateFormatter.format(value);
OurDate = dateFormatter.parse(n);
}catch (ParseException e){
e.printStackTrace();
}
return OurDate;
}
For pass date into Adapter
TimeDifference now = new TimeDifference(mContext,Utils.getDefaultDate(),Utils.newDate("Your current time");
Toast.makeText(context, "Posted by "+now.getDifferenceString(), Toast.LENGTH_SHORT).show();

In one of my applications I am trying to use recyclerview to display content. My content would be like chat history(it may be a single line text or multiple lines text).To implement this I have used recyclerview with Textview height as wrap_content to adjust the height based on the content. For the first time it is loading fine. But when I do scroll up and down I am getting some extra white space for some of the items. (I strongly suspect this extra space is for earlier item height).
Ex: I have a recyclerview list having 1,2,3,4,5.. lines text in each row. When I do scroll up down continuously I am getting row/item height is changing like 1 line text item got 5 lines text space and 5 lines text item got 1 line text.
Please find my adapter code below.

Thanks in Advance.
For sorting you need to Collection.sort method of Java and also you need to implement comparable interface for define your comparison.
CartItemoriginal implements Comparable {
public int compareTo(Object obj) { } }
Updated
public class CartItemoriginal implements Comparable<CartItemoriginal > {
private Float val;
private String id;
public CartItemoriginal (Float val, String id){
this.val = val;
this.id = id;
}
#Override
public int compareTo(ToSort f) {
if (val.floatValue() > f.val.floatValue()) {
return 1;
}
else if (val.floatValue() < f.val.floatValue()) {
return -1;
}
else {
return 0;
}
}
#Override
public String toString(){
return this.id;
}
}
and use
Collections.sort(sortList);
Before I change my design of my android application, I was wondering if I can retain the state of my fragment including all data collected when it is recreated. In my fragment i have an async task that collects the proper data usinf json and it publishes them to diffeerent cardviews. Here is my code:
LatestEventsFragment.java
public class LatestEventsFragment extends Fragment {
RecyclerView recyclerView;
RecyclerView.Adapter adapter;

ProgressDialog progressDialog;
#Nullable
#Override

LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getActivity());
recyclerView = (RecyclerView)view.findViewById(R.id.events_recycler);
linearLayoutManager.setOrientation(LinearLayoutManager.VERTICAL);
recyclerView.setLayoutManager(linearLayoutManager);
recyclerView.setHasFixedSize(true);
adapter = new EventsRecyclerAdapter(arrayList);
recyclerView.setAdapter(adapter);
EventsAsyncTask eventsAsyncTask = new EventsAsyncTask();
eventsAsyncTask.execute();
return view;
}
class EventsAsyncTask extends AsyncTask<String, Event, String> {
#Override
protected void onPreExecute() {
progressDialog = new ProgressDialog(getActivity());
progressDialog.setTitle("Please wait...");
progressDialog.setMessage("Loading");
progressDialog.setIndeterminate(true);
progressDialog.setCancelable(false);
progressDialog.show();
}
#Override
protected void onPostExecute(String s) {
progressDialog.dismiss();
}
#Override

adapter.notifyDataSetChanged();

You can use onSaveInstanceState inside your Fragment to save your data, then check the savedInstanceState variable inside onCreateView to see if it has data. If it does, just retrieve the data to recreate your view.
Inside Fragment:
#Override
public void onSaveInstanceState(Bundle savedInstanceState) {
// Always call the superclass so it can save the view hierarchy state
super.onSaveInstanceState(savedInstanceState);
if(mDataToSave != null) {
savedInstanceState.putString("myData", mDataToSave);
}
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View rootView = inflater.inflate(R.layout.fragment_main, container, false);
if(savedInstanceState != null){
String restoredData = (String)savedInstanceState.getString("myData");
//do something with restoredData
}
return rootView;
}
Just remember to change the put and get: savedInstanceState.putString() to savedInstanceState.put<WhateverYourDataTypeIs>()
If you're adding your Fragment through a Fragment Transaction in your Main Activity, make sure to only add it if the Main Activity's savedInstanceState is null. That way you won't replace the Fragment if it's already been added.
Inside Activity (if you have a Fragment Transaction):
if(savedInstanceState == null) {
Fragment newFragment = new MyFragment();
//add main fragment to fragment frame
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().add(R.id.fragment_container, newFragment).commit();
}
i working baseadapter.
i have two datetimeformat 09/01/2014 and 09/10/2014.i checked days between there datetimes
public String getDateDiffString(Date dateOne, Date dateTwo)
{
long timeOne = dateOne.getTime();
long timeTwo = dateTwo.getTime();
long oneDay = 1000 * 60 * 60 * 24;
long delta = (timeTwo - timeOne) / oneDay;
if (delta > 0) {
for (int i = 0; i < delta; i++) {
}
return String.valueOf(delta) ;
}
else {
delta *= -1;
return String.valueOf(delta);
}
}
and also i wrote funtciton to change there datetimes format 09/01/2014 i changed it 1 Sep
public static String dateFormatterforLukka(String inputDate,int lenght) {
String inputFormat = "MM/dd/yyyy";
String outputFormat = String.valueOf(lenght)+"MMM";
Date parsed = null;
String outputDate = "";
try {
SimpleDateFormat df_input = new SimpleDateFormat(inputFormat,
new Locale("en", "US"));
SimpleDateFormat df_output = new SimpleDateFormat(outputFormat,
new Locale("en", "US"));
parsed = df_input.parse(inputDate);
outputDate = df_output.format(parsed);
Log.wtf("outputDate", outputDate);
} catch (Exception e) {
outputDate = inputDate;
}
return outputDate;
}
now i want to add my datetimes in listview like this .betweeen days there two datetimes . 1 Sep,2 Sep etc...

when i run my app only 8 sep added always in my listview ,but i loged and in log i have
different result, meybe listview did not updated
what am i doing wrong? if anyone knows solution please help me
Create a methord in adapter class
public void setdata(ArrayList<CinemaInfoModel> hollitems_temp) {
this.hollitems=hollitems_temp;
}
for (int l = 0; l < abc; l++) {
String ab = dateFormatterforLukka(timeJsonArray
.getJSONObject(k).getString("start_time"),l++);
Log.wtf("timeeeeeeeee", ab);
cinemaTime.setStartTime(ab);
cinemaTime.setEndTime(_s1);
cinemaTimesArray.add(cinemaTime);
}
after this loop i am assuming that cinematimesarray is of type CinemaInfoModel
youradapter.setdata(cinemaTimesArray);
youradapter.notifyDataSetChanged();
put debugger in your getview methord and check;
I am working with Section list view in Android to show Call details according to date.
Means under a particular date number of call details. But when I get 2 calls under the same date, the last date is visible only and the list does not show the rest of the calls of that date.
Calls under different dates are shown correctly but calls under same date are not shown correctly, only the last call is shown.
