Give Permission in android Manifest file. :

My code is below:

  calendarView.setOnDateChangeListener(new CalendarView.OnDateChangeListener() {

            @Override

            public void onSelectedDayChange(@NonNull CalendarView calendarView, int i, int i1, int i2) {

                String date =(i2 + "/" + (i1 + 1) + "/" + i);

                showAlertDialog(date);



            }

        });



    }



    public void showAlertDialog(final String dateString1) {





        LayoutInflater inflater = this.getLayoutInflater();

        final View dialogView = inflater.inflate(R.layout.alert_dialog_item, null);





        final EditText etTitle = (EditText) dialogView.findViewById(R.id.etTitle);

        final EditText etEvent = (EditText) dialogView.findViewById(R.id.etEvent);



        final EditText etEventDate = (EditText) dialogView.findViewById(R.id.etStartDate);



        //final EditText etTime = (EditText) dialogView.findViewById(R.id.etTime);



        final EditText etEndDate = (EditText) dialogView.findViewById(R.id.etEndDate);



        Calendar cal = Calendar.getInstance();



        long date1 = cal.getTimeInMillis();

        SimpleDateFormat dateFormat = new SimpleDateFormat("MMM dd yyyy, HH:mm a");

        String dateString = dateFormat.format(date1);



        etEventDate.setText(dateString);



        long date2 = cal.getTimeInMillis() + 1000 * 60 * 60;

        String endDate = dateFormat.format(date2);

        etEndDate.setText(endDate);





        final AlertDialog.Builder builder = new AlertDialog.Builder(this);

        builder.setView(dialogView);

        builder.setTitle("Add Event");

        builder.setPositiveButton("ADD", new DialogInterface.OnClickListener() {

            @Override

            public void onClick(DialogInterface dialogInterface, int i) {



                String title = etTitle.getText().toString();

                String eventDescription = etEvent.getText().toString();

                String startDate = etEventDate.getText().toString();

                    cv = new ContentValues();

                    cv.put(CalendarContract.Events.DTSTART, startDate);

                    cv.put(CalendarContract.Events.DTEND, endDate);

                    cv.put(CalendarContract.Events.TITLE, title);

                    Uri uri = cr.insert(CalendarContract.Events.CONTENT_URI, cv);



                    if (ActivityCompat.checkSelfPermission(Event.this, Manifest.permission.READ_CALENDAR) != PackageManager.PERMISSION_GRANTED

                            && ActivityCompat.checkSelfPermission(Event.this, Manifest.permission.WRITE_CALENDAR) == PackageManager.PERMISSION_GRANTED){



                       // ContentResolver contentResolver = getContentResolver();

                        //ContentValues contentValues = new ContentValues();





                        long eventID = Long.parseLong(uri.getLastPathSegment());



                        Toast.makeText(Event.this, (int) eventID, Toast.LENGTH_SHORT).show();



                    }

            public void onClick(DialogInterface dialogInterface, int i) {

                builder.setCancelable(true);

            }

        });



        builder.show();



    }



    @Override

    public void onRequestPermissionsResult(int requestCode, String permissions, int grantResults) {





        switch (requestCode) {

                    Toast.makeText(this, " Permission is Granted", Toast.LENGTH_SHORT).show();



                } else {

                    //code for deny

                }
