Try this

public ArrayList<groups> fetchByTodayDate()
{
SQLiteDatabase db = this.getReadableDatabase();
ArrayList<groups> all = new ArrayList<>();

String selectQuery = "SELECT * FROM " + DatabaseHelper.TABLE;

Cursor cursor = db.rawQuery(selectQuery,null);

cursor.moveToFirst ();

while (!cursor.isAfterLast())
{
all.add(new groups (
cursor.getString(cursor.getColumnIndex(DatabaseHelper.TEXTMSG)),
cursor.getString(cursor.getColumnIndex(DatabaseHelper._ID))
));

cursor.moveToNext ();
}

cursor.close();
db.close();

return all;
}
