android - Android 部分 ListView 中缺少数据？

Question

我正在使用 Android 中的部分 ListView 来根据日期显示调用详细信息。指在特定日期下的通话详情号码。但是，当我在同一日期接到 2 个电话时，仅最后一个日期可见，列表不显示该日期的其余电话。

不同日期的通话显示正确，但同一日期的通话显示不正确，仅显示最后一次通话。

我正在使用下面的代码:

public String response = "{ \"Message\":\"Success\", "
        + "\"Data\":[ { \"ACCOUNT\":\"000014532497\", "

SectionListExampleActivity 是我的主类，我在其中从 JSON Web 服务获得响应。在 getJSONResposne 方法中，我调用了 EntryAdaptor。

每个标题的 SECTION HEADER 和 ITEM ENTRY 有两个单独的 geter setter 类。

public class SectionListExampleActivity extends Activity implements OnClickListener, OnItemSelectedListener, IServerResponse {
    /** Called when the activity is first created. */

    private ArrayList<Item> items = new ArrayList<Item>();
    boolean firstTime = true;

    private Spinner _spinner=null;
    private ArrayAdapter _amountAdaptor = null;
    private ArrayList<String> _monthList =new ArrayList<String>();
    private ListView _list=null;

    private Button _monthButton=null;
    private ImageButton _backImageButton=null;
    private ImageButton _headerImageButton=null;
    private String _token;
    private String _account;
    private Point p=null;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.account_history);

        String response = this.getIntent().getExtras().getString("history_resp");
        _token = Constant.AUTH_TOKEN;
        _account = Constant.ACCOUNT_NUM;

        _list = (ListView)findViewById(R.id.listview);
        getJSON_Response(response,Constant.PID_ACCOUNT_HISTORY);

        EntryAdapter adapter = new EntryAdapter(this, items);

        _list.setAdapter(adapter);

        _monthList.add("Months");
        _monthList.add("January");
        _monthList.add("February");
        _monthList.add("March");
        _monthList.add("April");
        _monthList.add("May");
        _monthList.add("June");
        _monthList.add("July");
        _monthList.add("August");
        _monthList.add("September");
        _monthList.add("October");
