Question

Iam fresher in android I selected Start date and end date from datepicker based on that I need to insert dates between start date and end date into sqllite and then compare with current date and set reminder. Please let me know if you have solution

Answer 1

To get date from Date picker use this

DatePicker datePicker = (DatePicker) findViewById(R.id.datePicker1);
int day = datePicker.getDayOfMonth();
int month = datePicker.getMonth() + 1;
int year = datePicker.getYear();

Set the values to database

public  void onDateSet(DatePicker view,int year,int monthOfYear,int dayOfMonth){
            dateTime.set(year,monthOfYear,dayOfMonth);

   int year = year;   // Here you can get day,month and year.
   int month = monthOfYear;
   int day = dayOfMonth;

ContentValues values = new ContentValues()

values.put("Day",dayOfMonth);
values.put("Month",monthOfYear);
values.put("Year",year);

}

You can get the database tutorials from here, here and here

To get Current date

String currentDateTimeString = DateFormat.getDateTimeInstance().format(new Date());

To set a reminder
you can use the alaram manager to set the reminder the solution can be found here

EDIT 2

private class myReminderTask extends AsyncTask<Void, Void, Void>{
    ArrayList<String> list = new ArrayList<String>();
    @Override
    protected Void doInBackground(Void... params) {
        while(true)
        for(String s : list){
            Date d = //Make date from the string obtained from SQL
            d.toString().equals(DateFormat.getDateTimeInstance().format(new Date()));

            //Create an alaram or notification
        }

        return null;
    }

    @Override
    protected void onPreExecute() {

        Cursor c = null;
        c = db.rawQuery("select startDate,endDate from tablename" , null);

        if (cursor.getCount() != 0)
            {
                if (cursor.moveToFirst())
                {
                    do
                    {
                        list.add(cursor.getString(cursor.getColumnIndex("FirstDate")));
                        list.add(cursor.getString(cursor.getColumnIndex("LastDate")));
                    } while (cursor.moveToNext());
                }
                db.closeDatabase();
            }
            cursor.close();

        super.onPreExecute();
    }

}

Do the entire thing on AsyncTask (example here also )so that the main UI thread is not blocked, on pre execute code the database fetching and on do in background use the while loop so that it never ends

This is what i can give rest you do the work… and that’s all, rest you have to search and work out your way don’t expect me to make and give an entire project
