Может кто-нибудь взглянуть на мой код здесь.Я пытаюсь сохранить некоторые данные из моего основного макета, используя метод onClick.здесь приведены коды для моего метода onClick
private OnClickListener bNextListener = new OnClickListener() {
public void onClick(View v) {
name=txt1.getText().toString();
email=txt2.getText().toString();
date = txtv.getText().toString();
gender = b4.getText().toString();
dbHelper.addProfiles(name, date, email, gender);
};
Каждый раз, когда я запускаю свое приложение, оно падает, потому что не удается сохранить данные метода addProfiles в моем классе dbHelper.Вот мой открытый класс класса dbHelper. SqlHelper extends SQLiteOpenHelper {public static final String DATABASE_PATH = "/data/data/com.and.profile/databases/";public static final String DATABASE_NAME = "profiledatabase.db";private static final int DATABASE_VERSION = 2;
public static final String PROFILES_TABLE = "profiles";
public static final String COLUMN_PROFILE_ID = "profile_id";
public static final String COLUMN_NAME = "name";
public static final String COLUMN_BIRTHDAY = "birthday";
public static final String COLUMN_EMAIL = "email";
public static final String COLUMN_GENDER = "gender";
public static final String INTERESTS_TABLE = "interests";
public static final String COLUMN_ID = "_id";
public static final String COLUMN_TITLE = "title";
public static final String COLUMN_SELECTED = "selected";
private static final String CREATE_TABLE_1 =
" create table " + PROFILES_TABLE +
" (" + COLUMN_PROFILE_ID + " integer primary key autoincrement," +
COLUMN_NAME + " name text not null, "+
COLUMN_BIRTHDAY +" birthday date not null, " +
COLUMN_EMAIL + "email text not null, " +

private static final String CREATE_TABLE_2 =

COLUMN_SELECTED +" selected integer);";

this.getWritableDatabase();
copyDBFromResource();

Я буду очень рад, если эксперты предоставят вам быструю помощь.Кстати, я использую файл базы данных в папке активов, если это необходимо.
