Answer 1

To insert a new row into sqlite , you can use an object of ContentValues class . See below the example (Let's consider that name, mobile , password and type are the key attribute and login is the name of the table ):

    ContentValues values = new ContentValues();
    values.put("name", nameValue);
    values.put("mobile", mobileValue);
    values.put("password", passwordValue);
    values.put("type", typeValue);

    long id = db.insert("login", null, values);
