How to add timestamps to an adapter

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

Create Utils.java and add this
public static Date getDefaultDate(){

SimpleDateFormat dateFormatter = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
f.setTimeZone(TimeZone.getDefault());
Date nowDate = new Date();
try {
nowDate = dateFormatter.parse(f.format(new Date()));
}catch (ParseException e){
e.printStackTrace();
}
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();

Countdown Timer sometime, counts 2 seconds before the actual time

I have tried to make an countdown timer in a list veiw implementation. Each list item has a separate countdown timer that can be started or stopped. However I have noticed that if I add the first timer in list and set its time. When I start the timer it starts two seconds less than the actual time. e.g If I added a count down of 12 seconds. Then it will start counting from 10. But when the countdown is taking place and I add another new timer and set its time, it starts on the exact given time. The new counter starts at the wrong time only when either there is no other counter in the list or when all counters are already stopped and not counting down. Similarly it will only start the right time only when other timers are counting down. Would really appreciate if someone can help me figure out where is the problem. I have been looking at the code for days.
Here's my Adapter class
public class CustomAdapterCounter extends ArrayAdapter<CounterData> {

And here's my CounterData class

}
public void setCounterID(int id) {
this.id = id;
}
public int getCounterID() {
return this.id;
}
}
And I add the time from number pickers of Hour, Minute and Second.
case R.id.counterStartStopButton:
long hour = TimeUnit.HOURS.toMillis(numberPickerHour.getValue());
long minute = TimeUnit.MINUTES.toMillis(numberPickerMinute.getValue());
long second = TimeUnit.SECONDS.toMillis(numberPickerSecond.getValue());
// if(getListSharedPreferences()) {
if(getCounterIDSharedPreferences()) {
counterID = counterID + 1;
list.add(new CounterData(hour + minute + second, counterID));
saveCounterIDSharedPreferences(counterID);
}
else {
counterID = 1;
list.add(new CounterData(hour + minute + second, counterID));
saveCounterIDSharedPreferences(counterID);
}
UPDATE
Here's the shared preferences code
public void saveCounterIDSharedPreferences(int id) {
SharedPreferences sharedPreferences = this.getSharedPreferences("com.example.app", Context.MODE_PRIVATE);
sharedPreferences.edit().putInt("Counter ID123", id).commit();
}
public boolean getCounterIDSharedPreferences() {
SharedPreferences sharedPreferences = this.getSharedPreferences("com.example.app", Context.MODE_PRIVATE);
if (sharedPreferences.getInt("Counter ID123", -1) != -1) {
counterID = sharedPreferences.getInt("Counter ID123", -1);
return true;
}
else
return false;
}

What turned out to work for me was changing the timer task as following:
private void startUpdateTimer() {
Timer tmr = new Timer();
tmr.schedule(new TimerTask() {
#Override
public void run() {
mHandler.post(updateRemainingTimeRunnable);
}
}, 500, 500);
}

Try like this :
progressDialog = new ProgressDialog(getActivity());
And if you wish to customize your dialog and put self created Layout in it.
/**
* Created by vivek on 18/10/16.
*/
public class CustomDialog {
private static Dialog dialog;
private static Context context;
public CustomDialog(Context context) {
this.context = context;
}
/**
* Comman progress dialog ... initiates with this
*
* #param message
* #param title
*/
public static void showProgressDialog(Context context, String title, String message) {
if (dialog == null)
{
dialog = new Dialog(context);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.custom_loader);
dialog.setCancelable(false);
dialog.setCanceledOnTouchOutside(false);
dialog.show();
}
}
public static boolean isProgressDialogRunning() {
if (dialog != null && dialog.isShowing()) {
return true;
} else return false;
}
/**
* Dismiss comman progress dialog
*/
public static void dismissProgressDialog() {
if (dialog != null && dialog.isShowing()) {
dialog.dismiss();
dialog = null;
}
}
} // End of main class over here ...

Replace this:-
progressDialog = new ProgressDialog(getContext(), ProgressDialog.THEME_HOLO_LIGHT);
with
progressDialog = new ProgressDialog(getActivity());

May be. you are showing two progressdialog and both of that progressbar on screen.. but when you dismiss your progressbar at that time the previous one is override by other one before you dismiss first one .. so the firstone is always in screen. that's the issue.

I tried everything.But none of the answers solved the issue.However,i solved it by overriding onResume() method in the fragment.
Thanks All.

When I am going to incerase qty then below screen shows
when I am scrolled down and up then below screen shows

You are not setting the initial value of holder.tvQty in your onBindViewHolder method.
When you update the value of holder.tvQty in holder.btnPlus or holder.btnMinus listeners, you should save that value somewhere in your objSellerProductPOJO:
objSellerProductPOJO.setQty(final_str_qty)
Then under:
holder.tvPrice.setText(objSellerProductPOJO.getPrice());
add:
holder.tvQty.setText(objSellerProductPOJO.getQty());

You need to update the productListDetails variable on add or subtract after
holder.tvQty.setText(final_str_qty);
And notify the adapter using notifydatasetchange()

In your onClick() methods, replace the the position parameter of the onBindViewHolder() method with the getAdapterPosition().
Replace from
SellerProductPOJO objSellerProduct = productListDetails.get(position);
SellerProductPOJO objSellerProductDeduct = productListDetails.get(position);
to
SellerProductPOJO objSellerProduct = productListDetails.get(getAdapterPosition());
SellerProductPOJO objSellerProductDeduct = productListDetails.get(getAdapterPosition());

Check the concept of view tags, that will help you out. basically do a seekbar.setTag("UNIQUE ID FOR EVERY VIEW"); then while updating the seekbar use findViewWithTag("UNIQUE ID FOR PARTICULAR VIEW")
since you are fetching view by id it will only give the last view with that id.
