Arraylistが同様のオブジェクトを格納する理由がわかりません。親切に私を助けてください。前もって感謝します。カーソルをループしたり、Arraylistに格納したりするロジックに問題があることはわかっています。配列リストは次のように定義されます。

public ArrayList<Object> results=new ArrayList<Object>();

public ArrayList<String> arrTemp=new ArrayList<String>();

以下は私のコードです：

db = getReadableDatabase();// /////--->Here database is opened
        cursor = db.rawQuery("Select symbol,date,open,high,Low,close from testTBL;", null);

        if (cursor.getCount() != 0) {

            while (cursor.moveToNext()) {

                arrTemp.clear();

                    arrTemp.add(cursor.getString(cursor.getColumnIndex("symbol")));
                    arrTemp.add(cursor.getString(cursor.getColumnIndex("date")));
                    arrTemp.add(cursor.getString(cursor.getColumnIndex("open")));
                    arrTemp.add(cursor.getString(cursor.getColumnIndex("high")));
                    arrTemp.add(cursor.getString(cursor.getColumnIndex("Low")));
                    arrTemp.add(cursor.getString(cursor.getColumnIndex("close")));

                Log.v("arrayTemp inside while loop", ""+arrTemp);

                results.add(arrTemp);
                Log.v("Results stored", ""+results);
            }

                Log.v("Final Results", ""+results);


            cursor.close();
        }

            db.close();

Logcatの出力は次のとおりです。

テーブル構造でPOJOクラスを作成してみませんか？好き

Class TestClass{
private String symbol;
private String date;
//etc
}

次に、このタイプのオブジェクトを含む配列リストを作成します。

public ArrayList<TestClass> results=new ArrayList<TestClass>();

この動作は、のコピーを保存しておらず、参照のみを保存しているために発生arrTempしresultsます。別々のリストではなく、常に同じオブジェクトを操作しています。arrTemp.clear()これで、whileループで呼び出されるたびに、に格納されている参照が実際にクリアされresultsます。次に、に新しい値を追加してからarrTemp、に別の参照を再度追加するとarrTemp、resultsの同じリストへの2つ（3、4 ...）の同一の参照が生成されresultsます。

簡単な解決策は、メンバー変数として宣言するのではなくarrTemp、次のようなwhileループ内で宣言することです。

while (cursor.moveToNext()) 
{
    ArrayList<String> arrTemp = new ArrayList<String>();

    //...
    // fill arrTemp
    //...

    results.add(arrTemp);
}
