即使我每次都在循環中初始化一個新對象，arraylist仍然會自我覆蓋自身。在循環內部，我能夠驗證檢索到的數據是正確的，但是當我在外面打印列表時，它只顯示覆蓋列表中其他元素的最後一個對象。對象列表自動覆蓋
public ArrayList<CODTripsDetails> getCODTrips()
{ SQLiteDatabase db = this.getReadableDatabase();
String[] projection = {
KEY_COD_CUST_NAME,
KEY_COD_DEL_FARE,
KEY_COD_DEL_ADDR,
KEY_COD_PICKDROP_DIST,
KEY_COD_PICKUP_ADDR,
KEY_COD_TIMESTAMP,
KEY_COD_ORDER_ID
};
Cursor cursor = db.query(TABLE_COD_DETAILS,projection,
null, null, null, null, null);
if (cursor != null)
cursor.moveToFirst();
assert cursor != null;
ArrayList<CODTripsDetails> array=new ArrayList<CODTripsDetails>();
while (!cursor.isAfterLast()) {
CODTripsDetails details=new CODTripsDetails();
details.setName(cursor.getString(0));
details.setdelFare(cursor.getString(1));
details.setdelAddr(cursor.getString(2));
details.setpickUpDropDist(cursor.getString(3));
details.setpickUpAddr(cursor.getString(4));
details.settimestamp(cursor.getString(5));
details.setorderid(cursor.getString(6));
Log.v("sql","sql=" +cursor.getString(3));
array.add(details);
cursor.moveToNext();
}
cursor.close();
db.close();
Log.v("sql","sql1="+array.get(0).getpickUpAddr());
Log.v("sql","sql1="+array.get(1).getpickUpAddr());
return array;
}
在此先感謝。
更新代碼：
這是我的檢索和添加數據的寫入整個mysqlitehelper類。
