Answer 1

if I understand you correctly, your challenge is querying the SQLite db, group the records into dates, and display them in sections in the view.

Take a look at this:

public String formatDate(long dateTime) {
    String formatedDate;
    Calendar calendar = Calendar.getInstance();
    calendar.setTimeInMillis(dateTime);
    Date mDate = calendar.getTime();
    SimpleDateFormat sdf;
    sdf = new SimpleDateFormat("EEEE dd EEEE", new Locale("en"));
    formatedDate = sdf.format(mDate);
    return formatedDate;
} 

SQLiteDatabase db = this.getReadableDatabase(); 
//select companies, order record by date-time created desc (or asc)
Cursor cursor = db.query(Company.TABLE_NAME, null, null,
        null, null, null, DatabaseHelper.KEY_CREATED_AT + " DESC", null);
String day="";
ArrayList childList= new ArrayList();
int index = 0;
ArrayList sectionHeaders = new ArrayList<>();
if (cursor.moveToFirst()){
      //assign the formatted current date to a variable

     day = formatDate(cursor.getString(cursor.getColumnIndex(DatabaseHelper.KEY_CREATED_AT)));
     String current_day = formatDate(cursor.getString(cursor.getColumnIndex(DatabaseHelper.KEY_CREATED_AT)));
     while(cursor.moveToNext()){
          current_day = formatDate(cursor.getString(cursor.getColumnIndex(DatabaseHelper.KEY_CREATED_AT)));
          childList.add(new Company(cursor.getColumnIndex(DatabaseHelper.KEY_COMPANY_NAME), getFromatDate(cursor.getString(cursor.getColumnIndex(DatabaseHelper.KEY_CREATED_AT))));
          //compare with day var
          if(!day.equals(current_day)) {
             //We are beginning a new day, so add the previous days company to the sectioned list
             sectionHeaders.add(new CompanySectionHeader(new ArrayList(childList), day, ++index));
             day=current_day; //this is 
             childList.clear();
          }
      }
}
cursor.close();
db.close();
//attach sectionHeaders to view here

I hope it helps.
