Reading Selected Date without DatePickeView in android studio

I am Parvanshu Sharma and I am a beginner to programming, I am making an application in which
I have done that on button click a date Picker dialog will appear and the button text will be set to the selected by the user, Currently there are 3 buttons for this and I even have a realtime database for uploading this date on Firebase, but now I am having problems in getting the every unique date and uploading it, I am not able to get the selected date.
And as my every stackoverflow question has-
MainActivity.java (Its too big so I haven't shown imports)
public class MainActivity extends AppCompatActivity implements DatePickerDialog.OnDateSetListener, AdapterView.OnItemSelectedListener {
String CurrentDateString;
TextView mainDate;
Integer OrderQuantity = 3;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button SelectDate1 = findViewById(R.id.SelectDateButton1);
Button SelectDate2 = findViewById(R.id.SelectDateButton2);
Button SelectDate3 = findViewById(R.id.SelectDateButton3);
SelectDate1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
DialogFragment datePicker = new DatePickerFragment();
datePicker.show(getSupportFragmentManager(), "Pick item order date");
mainDate = SelectDate1;
}
});
SelectDate2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
DialogFragment datePicker = new DatePickerFragment();
datePicker.show(getSupportFragmentManager(), "Pick item order date");
mainDate = SelectDate2;
}
});
SelectDate3.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
DialogFragment datePicker = new DatePickerFragment();
datePicker.show(getSupportFragmentManager(), "Pick item order date");
mainDate = SelectDate3;

and I have one more class for creating DatePickerDialog,
the source from where I learnt and implemented that how to make DatePickerDialog is Here
which goes here- (DatePickerFragment.java)
public class DatePickerFragment extends DialogFragment {
#NonNull
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Calendar c = Calendar.getInstance();
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH);
int day = c.get(Calendar.DAY_OF_MONTH);
return new DatePickerDialog(getActivity(), (DatePickerDialog.OnDateSetListener) getActivity(), year, month, day);
}
}

Tried using an interface. You will have all 3 dates in your main activity, now you can do whatever with them
public class DatePickerFragment extends DialogFragment {
private static applyDate mInterface;
private static int buttonNumberHere;
public interface applyDate {
void setDate(int selectedYear, int selectedMonth, int selectedDay, int buttonNumber);
}
public static DatePickerFragment newInstance(int buttonNumber, applyDate context)
{
DatePickerFragment fragment = new DatePickerFragment();
mInterface = ((applyDate) context);
buttonNumberHere = buttonNumber;
return fragment;
}
#NonNull
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Calendar c = Calendar.getInstance();
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH);
int day = c.get(Calendar.DAY_OF_MONTH);
return new DatePickerDialog(getContext(), datePickerListener, year, month, day);
}
private DatePickerDialog.OnDateSetListener datePickerListener = new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int selectedYear,
int selectedMonth, int selectedDay) {
mInterface.setDate(selectedYear, selectedMonth, selectedDay, buttonNumberHere);
}
};

Recyclerview is Scrolling when media Player is playing. How can i fix it?

I'm developing a ChatApp with the function of Audio Messages. The Recording and playing of this Audio Messages are working very well, but if i click on Play Button the Recyclerview is scrolling up. Anyone have an idea?
Sorry for my bad english, i'm from Germany ;)

Country code is not getting from country code picker in Android

I am developing an signup activity in android app. I want show the country telephone code(get the country from device). It may show the list of countries containing with flag, country telephone code, country name. I get the code of country code picker from https://github.com/mukeshsolanki/country-picker-android . It contain the complete code. I want to set the default country is in the phone.
TelephonyManager tm = (TelephonyManager)this.getSystemService(this.TELEPHONY_SERVICE);
String countryCodeValue = tm.getNetworkCountryIso();
System.out.println("country = "+country);
When i using this code i get the country code "in". But i want to display telephone code and flag, name. When i open the screen. I want to display it automatically.

String locale = context.getResources().getConfiguration().locale.getCountry();

You can use this library
Click here
by then you can do this
new DialogPlusBuilder().blurBackground()
.buildCountriesListDialog(true,new DialogPlus.CountriesDialogListener() {
#Override
public void onItemClicked(CountryDataModel countryDataModel, DialogPlus dialogPlus) {
super.onItemClicked(countryDataModel, dialogPlus);
Toast.makeText(MainActivity.this,countryDataModel.getName()+ countryDataModel.getPhone_code(), Toast.LENGTH_SHORT).show();
}
})
.show(this.getSupportFragmentManager(), "Countries List Dialog");

On click of correct icon if the edit text is empty a validation needs perform and show a toast message.

You need to use this check and print your toast in else part and your implementation in if part -
if (edittext.getText().length() > 0) {
// perform action here
} else {
// show toast here if edittext is empty
}
Hope it may be of help to you.

I am new over...
My question is: how to obtain the data from the edittext in fragments? I have really tried everything I have been seeking and no result.
Here is the code:

I don't know what I am doing wrong. I need to get access to those EditText in order to user them and add the user to the SQLite DB but, as the EditText are in the Fragment, I cannot access them directly from the RegisterUser class.
Any ideas on how to solve this? I shall be really and deeply thankful.
Thanks in advance.

Try doing like this,
TextInputLayout FlayoutBirthday= (TextInputLayout) v.findViewById(R.id.flayout_birthday);
EditText i_lname = FlayoutBirthday.getEditText();
