How to add multiple values inside 1 list view and style it approriatle

I want to be able to add multiple values on a list but properly style the list view.
For example right now the list view will look like this:
namepostcodedate
which is because of the following code
ListArray.add(jobs.get(finalJ).customer.getName() + job.getPostcode() + job.getDate());
The way that I am currently adding the values in the ListArray doesn't seem ideal but I am not sure if there is another way to do this and display the list formated?
This is my list_item file
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="fill_parent"

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;
}
});
ArrayAdapter<CharSequence> FoodAdapter = ArrayAdapter.createFromResource(this, R.array.FoodList, android.R.layout.simple_spinner_item);
FoodAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
Spinner SelectItem1 = findViewById(R.id.SelectItem1);
SelectItem1.setAdapter(FoodAdapter);
SelectItem1.setOnItemSelectedListener(this);
Spinner SelectItem2 = findViewById(R.id.SelectItem2);
SelectItem2.setAdapter(FoodAdapter);
SelectItem2.setOnItemSelectedListener(this);
Spinner SelectItem3 = findViewById(R.id.SelectItem3);

Quantity1.setAdapter(QuantityAdapter);
Quantity1.setOnItemSelectedListener(this);
Spinner Quantity2 = findViewById(R.id.SelectQuantity2);
Quantity2.setAdapter(QuantityAdapter);
Quantity2.setOnItemSelectedListener(this);
Spinner Quantity3 = findViewById(R.id.SelectQuantity3);
Quantity3.setAdapter(QuantityAdapter);
Quantity3.setOnItemSelectedListener(this);
Button DoneButton = findViewById(R.id.DoneButton);
EditText PersonName = findViewById(R.id.PersonName);
EditText PersonPhone = findViewById(R.id.PersonPhone);
EditText PersonAddress = findViewById(R.id.PersonAddress);
FirebaseDatabase database = FirebaseDatabase.getInstance();
DoneButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
DatabaseReference Name = database.getReference(PersonPhone.getText().toString() + "/Name");
Name.setValue(PersonName.getText().toString());
DatabaseReference Phone = database.getReference(PersonPhone.getText().toString() + "/Phone");
Phone.setValue(PersonPhone.getText().toString());
DatabaseReference Address = database.getReference(PersonPhone.getText().toString() + "/Address");
Address.setValue(PersonAddress.getText().toString());
if (Quantity1.getSelectedItem().toString().equals("0")) {
OrderQuantity -= 1;
}
if (Quantity2.getSelectedItem().toString().equals("0")) {
OrderQuantity -= 1;
}
if (Quantity3.getSelectedItem().toString().equals("0")) {
OrderQuantity -= 1;
}
DatabaseReference OrderQuantities = database.getReference(PersonPhone.getText().toString()+"/OrderQuantity");
OrderQuantities.setValue(OrderQuantity);
if (Quantity1.getSelectedItem().toString() != "0") {
//I want some solution HERE
}
}
});
}
#Override
public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
Calendar c = Calendar.getInstance();
c.set(Calendar.YEAR, year);

c.set(Calendar.DAY_OF_MONTH, dayOfMonth);
SimpleDateFormat format = new SimpleDateFormat("dd-MM-yyyy");

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);

Now, the cursor isn't empty but the listview is not displayed by the listview adapter.
Can someone point out the error in the code??

Please use this.
#Override
public int getCount() {
//here too;
return depart.lenght;
}
#Override
public Object getItem(int i) {
//there is error: repalce return null; with
return depart[i];
}
#Override
public long getItemId(int i) {
//change this too
return depart[i].getId();
}

I can see 2 reasons that this may happen:
You arrays are not filled with data/or filled with empty data and that the reason they are not presented. (less likely because you would receive a null pointer exception when you try to access a null location in the array)
Your row layout doesn't show data parameters. (I will be
on this reason, please show you row layout XML(listview_items.xml) so that we could check
it)
Check: Make a check and print to the log all the data from 6 the arrays for every row before you set the data in the getView method.

getCount(), getItem() and getItemId() are not set properly.
getCount() should return the number of items in the arraylist;
getItem() should return the item at the given position from the arraylist;
getItemId() should return the internal id of the item if it has one, or the position of the item in the array or an hash number of the item.

For call button in listview you can add call button icon in listview's row file like below:-
<Button
android:id="#+id/buttonCall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Call" />
Then in activity, you can write below code in on click of call button to call functionality in android:-
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("phone number"));
startActivity(callIntent);
phone number in above code is a string var in which you can add number which you want to call.
I hope it will help you.

Why the listview got extra space? Even i chg the padding in xml file it wont change. It happen when i add much id in viewholder. That means if in viewholder only gt 4 id the listview did not have extra space in the bottom of every item. How to do the spacing divided equally? Anyone help pls. Thanks.

Change height of listView to wrap_content.
