我在Android开发中作为编码员开始我的旅程。如果错误太简单，请原谅。 我正在面对我正在创建的SQLite数据库的问题，我无法解决它。

这是我尝试创建数据库并将数据添加到数据库表时出现的错误。 我运行的代码如下：
MedicineSQLiteHelper mMedicineSQLiteHelper = new MedicineSQLiteHelper(this);
SQLiteDatabase db = mMedicineSQLiteHelper.getWritableDatabase();
ContentValues values = new ContentValues();
values.put(MedEntry.COLUMN_MED_NAME, medicamentName);
values.put(MedEntry.COLUMN_DOSAGE, dosage);
values.put(MedEntry.COLUMN_ICON_ID, icon);
values.put(MedEntry.COLUMN_NUMBER_OF_HOURS, Integer.parseInt(numberOfHours));
values.put(MedEntry.COLUMN_HOURS_DAYS, hourDaySpinnerContent);
values.put(MedEntry.COLUMN_HOURS, hourSelected);
values.put(MedEntry.COLUMN_MINUTES, minuteSelected);
values.put(MedEntry.COLUMN_DAY, day);
values.put(MedEntry.COLUMN_MONTH, month);
values.put(MedEntry.COLUMN_YEAR, year);
long newRowId = db.insert(MedEntry.TABLE_NAME, null, values);
MedicineSQLiteHelper类如下：
public class MedicineSQLiteHelper extends SQLiteOpenHelper {
private static final String DB_NAME = "medicine.db";
private static final int DB_VERSION = 1;
public MedicineSQLiteHelper(Context context) {
super(context, DB_NAME, null, DB_VERSION);
}
@Override
public void onCreate(SQLiteDatabase db) {
String SQL_CREATE_MEDS_TALBE = "CREATE TABLE IF NOT EXISTS " + MedEntry.TABLE_NAME + " ( "
+ MedEntry._ID + " INTEGER PRIMARY KEY, "
+ MedEntry.COLUMN_MED_NAME + " TEXT ,"
+ MedEntry.COLUMN_DOSAGE + " TEXT ,"
+ MedEntry.COLUMN_ICON_ID + " INTEGER ,"
+ MedEntry.COLUMN_NUMBER_OF_HOURS + " INTEGER ,"
+ MedEntry.COLUMN_HOURS_DAYS + " TEXT ,"
+ MedEntry.COLUMN_HOURS + " INTEGER ,"
+ MedEntry.COLUMN_MINUTES + " INTEGER ,"
+ MedEntry.COLUMN_DAY + " INTEGER ,"
+ MedEntry.COLUMN_MONTH + " INTEGER ,"
+ MedEntry.COLUMN_YEAR + " INTEGER );";
db.execSQL(SQL_CREATE_MEDS_TALBE);
onCreate(db);
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
onUpgrade(db, oldVersion, newVersion);
}
我的理解告诉我这是一个与未关闭游标有关的问题？
我希望我已经添加了所有必要的信息，如果有人为我提供了一些代码向我解释错误，我将非常感谢！ ：）
