从Calenderview添加事件，并与Android设备Calander同步添加事件

Question

我必须创建calendarview和Add事件。此添加事件与Android设备日历同步。意思是，使用Android设备日历中的CalendarView Show添加事件。如何在Android设备日历中显示此事件。

如何进行此活动15分钟前发出提醒。

我在清单文件中提到了权限：

<uses-permission android:name="android.permission.READ_CALENDAR"/>
    <uses-permission android:name="android.permission.WRITE_CALENDAR"/>

下面的代码为“读取和写入日历”权限提供了错误。

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);

        }
    });

    permission();
}

public void showAlertDialog(final String date){


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


   // eventDate.setText((new StringBuilder().append(day).append("/").append(month+1).append("/").append(year)));

    etEventDate.setText(date);

    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 event = etEvent.getText().toString();
            String date = etEventDate.getText().toString();
            String time = etTime.getText().toString();

            calendarEvent(title, event,date,time);
            try {
                String eventUriString = "content://com.android.calendar/events";
                ContentValues eventValues = new ContentValues();
                eventValues.put("calendar_id", 1); // id, We need to choose from
                // our mobile for primary its 1
                eventValues.put("title", title);
                eventValues.put("description", event);


                //long endDate = Long.parseLong(date + 1000 * 10 * 10); // For next 10min
                eventValues.put("dtstart", date);

                eventValues.put("time", time);

                eventValues.put("eventTimezone", "UTC/GMT +5:30");

                eventValues.put("hasAlarm", 1); // 0 for false, 1 for true

                uri = getApplicationContext()
                        .getContentResolver()
                        .insert(Uri.parse(eventUriString), eventValues);
               long  eventID = Long.parseLong(uri.getLastPathSegment());
            } catch (Exception ex) {

                ex.printStackTrace();
            }

        }
    });

    builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialogInterface, int i) {
            builder.setCancelable(true);
        }
    });

    builder.show();
