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
public class TimeDifference {
int years;

Create Utils.java and add this
public static Date getDefaultDate(){
SimpleDateFormat f = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
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();

Can fragments retain the state of collected data of cardviews

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:

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();
}

Get the value of clicked Item of a custom listview?

I have created a Custom listview and set data by parsing a link and sorted them inside the list. Now when I am going to make a click and get the value of the individual object of a row I can't get the object of clicked row.

long id) {
EventParsingClass obj = (EventParsingClass) parent.getItemAtPosition(position);
Toast.makeText(getApplicationContext(), obj.getPlace_city() + "Clicked",Toast.LENGTH_LONG).show();
}
}
How can I proceed in these two scenarios?
EventParsingClass EPSP= ??? and
EPSP.getid= ??

fetch[0]="XXX"
fetch[1]="YYY"
fetch[2]="ZZZ"
lv.setOnItemClickListener(MainActivity.this);
public void onItemClick(AdapterView<?> parent, View view, int position,long id)
Toast.makeText(getApplicationContext(), fetch[position] + "Clicked",
Toast.LENGTH_LONG).show();
}
just declare fetch[position] to get the value of clicked item. hope this will give you some solution.

Use int position to find out values from your data list (array list or what ever you used).
lv.setOnItemClickListener(MainActivity.this);
public void onItemClick(AdapterView<?> parent, View view, int position,long id)
Toast.makeText(getApplicationContext(), EPSP.getid(position) + "Clicked",Toast.LENGTH_LONG).show();
}

EventItem item = (EventItem) parent.getItemAtPosition(position);
Now you have a hold of EventItem. So you can start using the get methods of your EventItem class in order to get whatever you want from it.

I got the solution:
EventParsingClass new_method(int value) {
int item_count = 0;
for (int i = 0; i < arrayOfEventDescription.size(); i++) {
ArrayList<EventParsingClass> Arraylist_for_loop = arrayOfEventDescription
.get(i);
item_count++;
for (int j = 0; j < Arraylist_for_loop.size(); j++) {
if (value == item_count) {
return Arraylist_for_loop.get(j);
}
item_count++;
}
}
return null;
}
And call it from here:
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
EventParsingClass newObject = new_method(arg2);
if (newObject == null) {
} else {
Log.d("Generated Value Id : ", "" + newObject.getId());
Toast.makeText(getApplicationContext(),
"Item Clicked" + arg2 + "-----" + newObject.getTitle(),
Toast.LENGTH_LONG).show();
}
}

Missing data in Section list view in Android?

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.
I am using the below code:

Android: Data in grid view appearing with delay

In my app, I have requirement of showing calendar. Since, calendar view is available from API level 11, so, I used grid view instead. Basically, I follwed this tutorial. Calendar is working, but data in Calendar in appearing with delay, means, when I click on button to display the calendar, it comes up after delay of around 5-10 seconds. I even tested with disabling the log, which I have put in the program, but it didn't made any difference. I am posting my code below.
Calendar Adapter
public class CalendarAdapter extends BaseAdapter //implements OnClickListener
{
static final int FIRST_DAY_OF_WEEK = 0; // Sunday = 0, Monday = 1
private Context mContext;
private Calendar month;

In my calendar, I have to highlight the dates which have some event. And, on click of highlighted date, it will show the list of events on that date. Every thing is working. except the calendar appears with delay even if I change month. I am not getting the cause.

One of the possible causes of the delay may be the call to Typeface.createFromAsset() which is called for every cell. The createFromAsset() method consumes a lot of resources.
To mitigate this, you could create a singleton class that retains the typeface used, so the font is not generated from the font file every time. Or you initialize it in onCreate() and pass it as an argument to the CalendarAdapter constructor and then use that instance in getView().
(To test this assumption comment the lines that sets the font to txtCurMonth TextView, and see if any difference)
