listview-Android ListView重復加載的問題

Android ListView重復加載的問題

我建立一個 ListViewView，並重寫了自己的 adapter（繼承BaseAdapter）,數據源是一個ArrayList.
，ArrayList裡的數據是 1,2,3。當我初始化 ListView時，顯示的是 1,2,3。
以上看起來非常正常，但當我按 後退鍵，然後重新 進入 ListView的時候，詭異的事情就發生了。。
當我第二次進入 ListView的時候，屏幕上顯示的 數據 成了 1,2,3, 1,2,3 .
然後我按下 後退鍵，再進入 ListView， 屏幕上的 數據 成了 1,2,3, 1,2,3 ,1,2,3

如此循環往復。。總之，每次進入ListView，都得重新讀取ArrayList的數據。請問是什麼原因導致的呢？
以下是adapter源碼
public class chatListAdapter extends BaseAdapter{

private Context context;                        //運行上下文   
private List<Map<String, Object>> listItems;    //聯系人信息集合   
private LayoutInflater listContainer;           //視圖容器   
private boolean[] hasChecked;                   //記錄聯系人選中狀態   
public final class ListItemView{                //自定義控件集合     


        public TextView RemoteAudio;
        public TextView LocalAudio;
        public TextView RemoteId;     
        public TextView LocalId;
        public TextView MessageType;

        public ImageView RemoteImage;
        public ImageView LocalImage;
        public TextView RemoteSay;
        public TextView LocalSay;

 }     
public chatListAdapter(Context context, List<Map<String, Object>> listItems) {   
    Log.v("construtor", "constructor11");
    this.context = context;            
    listContainer = LayoutInflater.from(context);   //創建視圖容器並設置上下文   
    this.listItems = listItems;   
    hasChecked = new boolean[getCount()];

最佳回答：

看你數據源的ArrayList，是不是靜態變量，而且每次初始化的時候都沒有clear。
