RecyclerView empty after data update

I am developing Android app which obtains information about restaurants from server and shows them in RecyclerView. When first package of information is obtained from server, everything works as expected, but, when I change search criteria and request new package of information from server, RecyclerView becomes blank. I used Toasts to debug what is coming from server and I am convinced that data is properly formatted. Also, variables that are used for accepting the data are also properly handled in code, according to my observations. Do you maybe know why my RecyclerView is empty when second package of data should be shown? Here is the code.

Add this lines after getting new data
myAdapter.notifyDataSetChanged()

Your Adapter Already set with RecyclerView in OnCreate Method.
so when'er you click on findRestaurantButton you just get Resturent data from server but collected data not pass in adapter so thats why to getting blank adapter..
Just put this line in your onResponse after set data in array..
myAdapter.notifyDataSetChanged()

I found out where is the mistake. If you take a look at the section where overriding of back button click is happening, I by mistake set to GONE recyclerView itself:
restaurantsRecyclerView.setVisibility(View.GONE);
instead of LinearLayout in which recyclerView is contained. Desired action was:
restaurantListLayout.setVisibility(View.GONE);
P.S. Everything works without calling notifyDataSetChanged(), I just create a new instance of myAdapater each time when I receive new data. I hope Garbage Collector is doing its job :)
Thanks everyone on help!

EDIT 2, I fixed the problem, I just put the bundle in both onCreate and onMenuItemSelected

case R.id.itemStats:
selectedFragment = new FragmentDashboard();
ArrayList<AppListModel> arrayList = new ArrayList<>(list.size());
arrayList.addAll(list);
Bundle bundle = new Bundle();
bundle.putInt("totalUsage", totalUsage);
bundle.putParcelableArrayList("arrayList", arrayList);
selectedFragment.setArguments(bundle);
break;
case R.id.itemDashboard:
selectedFragment = new FragmentDashboard();
break;
In this part of your code you instantiate FragmentDashboard in two case statement which in second one you did not pass any bundle as arguments and because this you get error when you call getArguments().get... in it.

You only set the arguments on your FragmentStats instance. Other fragments such as the FragmentDashboard seen in the stacktrace don't have arguments set, and getArguments() returns null.
If you want the same arguments to be applied to all fragments, move the Bundle setup and setArguments() after the switch-case. (And maybe add a default case too so selectedFragment won't ever be null.)

How to add new feed to recycleview at same time without scroll or refresh the view?

I have an activity in which I have used Recycle View to show all items as a list. On same activity I have given functionality to add new item. Everything is working fine. Items are adding in my database and its showing in list. I have added pagination on Recycle View it is also working fine. What I want that when user add new item at the same time when new data added to database but it is not updating in list. When user press back and again come on activity after that it is showing in list. I want to add add new item at same time without scroll the list or without go back.

You have to notifiy dataset changed on listview when new feed is added so there are two things you can do :
Create a new TimeLineItem item when new feed is entered and add new item to it like this :
`
item.setStatus("New Status");
item.setProfilePic("New Profile Pic");
item.setTimeStamp("New TimeStamp");
item.setIsLike("True");
item.setTotalLikes("1000");
item.setTotalComment("2");
`
and then use timeLineItems.add(item) to add new item to ArrayList and call adapter.notifyDataSetChanged(); to get it in view .
2. Again create volley request and it will do it automatically but this is slower then above example.
If you have any query please ask .

You have to set this new list to the adapter.
You can create a setDataSet() method in your adapter and call it before notifydatasetchanged
Add below method in adapter
public void setDataSet(List<TimeLineItem> timeLineItems) {
this.timeLineItems = timeLineItems;
}
and call it before notifydatasetChanged like this:
adapter.setDataSet(timeLineItems);
adapter.notifyDataSetChanged();

Following is the code to display my List ITEMS. I wanted my 5th row item i.e UPI to be enabled copying when long pressed on it. How do I do this? Please edit my code for the same to happen.

Change in layout file: add the below property to your TextView:
android:textIsSelectable="true"
OR
In your Java class write this line to set it programatically:
myTextView.setTextIsSelectable(true);
Copy text:
tv.setOnLongClickListener(new View.OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
ClipboardManager clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
ClipData clip = ClipData.newPlainText("", tv.getText());
clipboard.setPrimaryClip(clip);
Toast.makeText(context, "Copied to clipboard", Toast.LENGTH_SHORT).show();
return true;
}
});
Make sure you have imported android.content.ClipboardManager and NOT android.text.ClipboardManager.

In your row_layout for your ListView, just add the property android:textIsSelectable to the TextView on which you want copying to be allowed.

How to pass checkbox values to an ACTION_SEND

I'm trying to do my first app, I'm self-taught in Java and I started 2 month ago so please forgive my errors.
I want to pass the CheckBoxes values to an email text but I think I need to refresh "something" before sending the email because the values are always false..and I don't know how can I do.
Here is the code:
public class Appuntamento extends Activity{
String paziente;
#Override
protected void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.appuntamento);
//riceviamo id e lo mettiamo come nome utente
final EditText nomePaziente = (EditText)findViewById(R.id.nomePaziente);
Bundle dati = this.getIntent().getExtras();
nomePaziente.setText(dati.getString("id"));
final String id = dati.getString("id");
EditText noteAppuntamento = (EditText)findViewById(R.id.noteAppuntamento);
final String note = noteAppuntamento.getText().toString();
final CheckBox lunedi = (CheckBox) findViewById(R.id.checkboxLunedi);
final boolean lun = lunedi.isSelected();
final CheckBox martedi = (CheckBox) findViewById(R.id.checkboxMartedì);
final boolean mar = martedi.isSelected();
final CheckBox mercoledi = (CheckBox) findViewById(R.id.checkboxMercoledi);
final boolean mer = mercoledi.isSelected();
final CheckBox giovedi = (CheckBox) findViewById(R.id.checkboxGiovedi);
final boolean giov = giovedi.isSelected();
final CheckBox venerdi = (CheckBox) findViewById(R.id.checkboxVenerdi);
final boolean ven = venerdi.isSelected();
StringBuilder testoMail = new StringBuilder();
if (lun ){
testoMail.append("Lunedì");
} else if (mar){
testoMail.append("Martedì");
}else if (mer) {
testoMail.append("Mercoledì");
} else if (giov) {
testoMail.append("Giovedì");
} else if (ven) {
testoMail.append("Venerdì");
}
final String giorni = testoMail.toString();
Button richiestaAppuntamento = (Button)findViewById(R.id.btnRichiestaAppuntamento);
richiestaAppuntamento.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent mail = new Intent(Intent.ACTION_SEND);
mail.setType("message/rfc822");
mail.putExtra(Intent.EXTRA_SUBJECT, "Richiesta appuntamento");
mail.putExtra(Intent.EXTRA_TEXT, "Nome paziente: " + id + " " + giorni + " " + "Note: " + note);
mail.putExtra(Intent.EXTRA_EMAIL, new String[] {"dottcastellitto#gmail.com"});
startActivity(mail);
}
});
}
}

two way you can do this one
like
public class Appuntamento extends Activity
{
String paziente;
boolean lun,mar ,mer,giov,ven;
#Override
protected void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.appuntamento);
//riceviamo id e lo mettiamo come nome utente
final EditText nomePaziente = (EditText)findViewById(R.id.nomePaziente);
Bundle dati = this.getIntent().getExtras();
nomePaziente.setText(dati.getString("id"));
final String id = dati.getString("id");
EditText noteAppuntamento = (EditText)findViewById(R.id.noteAppuntamento);
final String note = noteAppuntamento.getText().toString();
final CheckBox lunedi = (CheckBox) findViewById(R.id.checkboxLunedi);
final CheckBox martedi = (CheckBox) findViewById(R.id.checkboxMartedì);
final CheckBox mercoledi =(CheckBox)findViewById(R.id.checkboxMercoledi);
final CheckBox giovedi = (CheckBox) findViewById(R.id.checkboxGiovedi);
final CheckBox venerdi = (CheckBox) findViewById(R.id.checkboxVenerdi);
Button richiestaAppuntamento = (Button) findViewById(R.id.btnRichiestaAppuntamento);
richiestaAppuntamento.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
ven = venerdi.isChecked();
lun = lunedi.isChecked();
mar = martedi.isChecked();
mer = mercoledi.isChecked();
giov = giovedi.isChecked();
StringBuilder testoMail = new StringBuilder();
//your code this is fine if only one selected item info or data you want to send in mail
if (lun ){
testoMail.append("Lunedì");
} else if (mar){
testoMail.append("Martedì");
}else if (mer) {
testoMail.append("Mercoledì");
} else if (giov) {
testoMail.append("Giovedì");
} else if (ven) {
testoMail.append("Venerdì");
}
// if you want all then comment above code and uncomment below code
/*
if (lun ){
testoMail.append("Lunedì");
}
if (mar){
testoMail.append("Martedì");
}
if (mer) {
testoMail.append("Mercoledì");
}
if (giov) {
testoMail.append("Giovedì");
}
if (ven) {
testoMail.append("Venerdì");
}
*/
String giorni = testoMail.toString();
Intent mail = new Intent(Intent.ACTION_SEND);
mail.setType("message/rfc822");
mail.putExtra(Intent.EXTRA_SUBJECT, "Richiesta appuntamento");
