save و load اطلاعات در داخل گوشی اندروید توسط کد نویسی؟

شما باید از SQLite استفاده کنی، فکر کنم فصل 14

اینها هم کد مربوط به آموزش مهندس آقاجانی:

INSERT INTO person (person_name,person_family,person_age) VALUES ('Hossein','Kurd',26)

SELECT * FROM person WHERE person_age > 10

DELETE FROM person WHERE person_name LIKE '%Name%'

UPDATE person SET person_name='New Name' WHERE person_age>7

ContentValues cv = new ContentValues();
cv.put("fldConent", txtDescAE.getText().toString());
G.db.update(note.nameOfTable, cv, "id=" + txtIDAE.getText().toString(), null);
