と私のメインの活動に：私は、データベースクラスを持っている私のようにエラーを取得しています
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
try {
DBHandler db = new DBHandler(this);
// Inserting Account/Rows
Log.d("Insert: ", "Inserting ..");
db.addAccount(new Account(1, "Admin", "[email protected]", "admin", 23, "Type 1","Male", 180, 70));
// Reading all accounts
Log.d("Reading: ", "Reading all accounts..");
List<Account> accounts = db.getAllAccounts();
for (Account account : accounts) {
String log = "Id: " + account.getId() + " ,Name: " + account.getNameAndSurname();
// Writing accounts to log
Log.d("Account: : ", log);
}
TextView tx = (TextView) findViewById(R.id.txt);
tx.setText(db.getAccount(1).getNameAndSurname());
} catch (Exception e) {
String log = e.toString();
Log.d("ERROR: ", e.toString());
}
}
}
。
テーブルアカウントは性別
= 23パスワード性別=男性TypeOfDiabetes =タイプ1のid = 1 [email protected] NameAndSurname =管理体重= 70身長= 180年齢を挿入するエラー=管理者
という名前の列がありませんと
いいえ、そのようなコラム：パスワード
あなたは最高です！ –
