How can I extract date from CalendarView and display selected date?

Currently I am using code below and I can get current date to be dispalyed in Text field. However I have no idea how to display selected date.

I also used DatePicker and it displays selected date fine, however I would prefer CalendarView. Thanks

Calendar c = Calendar.getInstance();
        SimpleDateFormat ss = new SimpleDateFormat("dd-MM-yyyy");
        Date date = new Date();
        String currentdate= ss.format(date);
        TextView editText = (TextView) this.findViewById(R.id.textfield1);
        editText.setText(currentdate);

Simple Kotlin code to get selected date from CalenderView:

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <CalendarView
        android:id="@+id/calendar_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <Button
        android:id="@+id/button"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Toast Selected Date" />

</LinearLayout>

MainActivity.kt

import android.os.Bundle
import android.text.format.DateFormat
import android.util.Log
import android.widget.CalendarView
import android.widget.Toast
import androidx.appcompat.app.AppCompatActivity
import com.example.testandcheck.databinding.ActivityMainBinding
import java.util.*

class MainActivity : AppCompatActivity() {

private lateinit var binding: ActivityMainBinding   // Binding object for ViewBinding.

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    binding = ActivityMainBinding.inflate(layoutInflater)
    setContentView(binding.root)

    // Set date change listener on calenderView.
    // Callback notified when user select a date from CalenderView on UI.
    binding.calendarView.setOnDateChangeListener { calView: CalendarView, year: Int, month: Int, dayOfMonth: Int ->

        // Create calender object with which will have system date time.
        val calender: Calendar = Calendar.getInstance()

        // Set attributes in calender object as per selected date.
        calender.set(year, month, dayOfMonth)

        // Now set calenderView with this calender object to highlight selected date on UI.
        calView.setDate(calender.timeInMillis, true, true)
        Log.d("SelectedDate", "$dayOfMonth/${month + 1}/$year")
    }

    // Example button to show get selected date from CalenderView and show in Toast.
    binding.button.setOnClickListener {

        // Fetch long milliseconds from calenderView.
        val dateMillis: Long = binding.calendarView.date

        // Create Date object from milliseconds.
        val date: Date = Date(dateMillis)

        // Get Date values and created formatted string date to show in Toast.
        val selectedDayOfWeek = DateFormat.format("EEEE", date) as String // Monday
        val selectedDay = DateFormat.format("dd", date) as String // 05
        val selectedMonthString = DateFormat.format("MMM", date) as String // Jul
        val selectedMonthNumber = DateFormat.format("MM", date) as String // 6 --> Month Code as Jan = 0 till Dec = 11.
        val selectedYear = DateFormat.format("yyyy", date) as String // 2021

        val strFormattedSelectedDate = "$selectedDay-${selectedMonthNumber + 1}-$selectedYear ($selectedDayOfWeek)"
        Toast.makeText(applicationContext, "Selected Date = $strFormattedSelectedDate", Toast.LENGTH_SHORT).show()
    }
}

}

Note: Once you select any date on CalenderView it will just highlight that day but not select. Due to this reason you will always get system's current date-time when you call calendarView.date (kotlin) or calenderView.getDate() (Java). So you have to implement the setOnDateChangeListener. Upon receiving callback, you have to programmatically set the new Date object as shown.

Hope it helps...... Happy Coding...... :)

Calendar c = Calendar.getInstance();
    SimpleDateFormat ss = new SimpleDateFormat("dd-MM-yyyy");
    Date date = new Date();

    TextView editText = (TextView) this.findViewById(R.id.textfield1);
    editText.setText(currentdate);

above one is ur code try below code

CalendarView cv = (CalendarView)findViewById(R.id.cv1);
Calendar c = Calendar.getInstance();
    SimpleDateFormat ss = new SimpleDateFormat("dd-MM-yyyy");
    Date date = new Date(cv);
    String currentdate= ss.format(date);
    TextView editText = (TextView) this.findViewById(R.id.textfield1);
    editText.setText(currentdate);

CalendarView view = new CalendarView(this);
setContentView(view);

view.setOnDateChangeListener(new OnDateChangeListener() {

    @Override
    public void onSelectedDayChange(CalendarView arg0, int year, int month,
        int date) {
        Toast.makeText(getApplicationContext(),date+ "/"+month+"/"+year,4000).show();
    }
});

CalendarView view = new CalendarView(this);
setContentView(view);

view.setOnDateChangeListener(new OnDateChangeListener() {

    @Override
    public void onSelectedDayChange(CalendarView arg0, int year, int month,
        int date) {
        Toast.makeText(getApplicationContext(),date+ "/"+month+"/"+year,4000).show();
    }
});

This will display the user selected date.

in onCreate : 

 CalendarView v = new CalendarView( this );
 v.setOnDateChangeListener( new CalendarView.OnDateChangeListener() {
    public void onSelectedDayChange(CalendarView view, int year, int month, int dayOfMonth) {
       this.calendar = new GregorianCalendar( year, month, dayOfMonth );
    }//met
 });

Calendar c = Calendar.getInstance();

Calendar is different from CalendarView. CalendarView is a descendant of View so it has many event handlers, like an onClickListener. Perhaps this is what you are trying to find?
