how to set spinner textview I want a separate textview to show if the text in the spinner is clicked?

There are three buttons namely spinner,spinner2,spinner3 and next button there is sumbit button. sumbit button is clicked then show should be displayed in the TEXTVIEW.

spinner:DD

Spinner:mm

spinner:yyy

I want it in calendar format

TextView textView = (TextView) findViewById(R.id.textView2);

    String [] values =
        {"1","2","3","4","5","6","7","8","9","10","11","12","13","14","15","16","17","18","19","20","21","22","23","24","25","26","27","28","29","30","31"};
String [] values2 =
        {"1","2","3","4","5","6","7","8","9","10","11","12"};
String [] values3 =
        {"2023"};
Spinner dd = (Spinner) findViewById(R.id.spinner);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, values);
adapter.setDropDownViewResource(android.R.layout.simple_dropdown_item_1line);
dd.setAdapter(adapter);

Spinner mm = (Spinner) findViewById(R.id.spinner2);
ArrayAdapter<String> adapter2 = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, values2);
adapter2.setDropDownViewResource(android.R.layout.simple_dropdown_item_1line);
mm.setAdapter(adapter2);

Spinner yyyy = (Spinner) findViewById(R.id.spinner3);
ArrayAdapter<String> adapter3 = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, values3);
adapter3.setDropDownViewResource(android.R.layout.simple_dropdown_item_1line);
yyyy.setAdapter(adapter3);

Button sumbit= (Button) findViewById(R.id.sumbit);

TextView textView = (TextView) findViewById(R.id.textView2);

Solution

A) using array

 Spinner spinner = findViewById(R.id.spinner); //day spinner.
      ArrayList<String> arrayListdays = new ArrayList<>();
      arrayListdays.add("1","2","3","4","5","6","7","8","9","10","11","12","13","14","15","16","17","18","19","20","21","22","23","24","25","26","27","28","29","30","31");
      ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this,                         android.R.layout.simple_spinner_item, arrayListdays);
      arrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
      spinner.setAdapter(arrayAdapter);

similarly for month and year,

then button click,

btnGet.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    tvw.setText(spinner.getSelectedItem().toString()+"-"+spinner1.getSelectedItem().toString()+"-"+spinner2.getSelectedItem().toString());
                }
            });

B) using spinner alternatively, try like below,

1). for spinner like date for day,month, year use below xml, in datepicker use property android:datePickerMode="spinner" like below.

<DatePicker
    android:id="@+id/datePicker1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:datePickerMode="spinner"
    android:calendarViewShown="false"/>

2). on button click you need value in textview for this,

public class MainActivity extends AppCompatActivity {
    DatePicker picker;
    Button btnGet;
    TextView tvw;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        tvw=(TextView)findViewById(R.id.textView1);
        picker=(DatePicker)findViewById(R.id.datePicker1);
        btnGet=(Button)findViewById(R.id.button1);
        btnGet.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                tvw.setText("Selected Date: "+ picker.getDayOfMonth()+"/"+ (picker.getMonth() + 1)+"/"+picker.getYear());
            }
        });
    }
}

if still have issue, please comment.
