ListView滾動後出錯

我有一個ListView用於在我的應用程序中顯示一些問題。當我ListView顯示，在第一次使用前我把它的滾動，一切看起來正常，直到我向下滾動，在我ListView向上滾動，在列表中的一些觀點從我ListView是如下改變：ListView滾動後出錯

1. ListView before Scroll

ListView before Scroll

2.ListView After Fisrt Scroll

ListView After Fisrt Scroll

3. ListView After next Scroll

ListView After next Scroll

我不知道這是爲什麼發生在我ListView，我已經搜查了許多解決方案，但似乎沒有真正幫助我，這是我的代碼來調用我的適配器：

@Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
      Bundle savedInstanceState) { 
     // Inisialisasi layout utama 
    kuisioner = inflater.inflate(R.layout.new_quisioner, container, false); 
    //ListView 
    list_tt = (ListView)kuisioner.findViewById(R.id.list_tt); 
    //list 
    listQuisioner = new ArrayList<ModelListQues>(); 
    lisLabelQues = new ArrayList<ModelLabelQues>(); 
    me=((ModelESPAJ)getActivity().getApplication()); 
    helper=new DBSpaj(getActivity()); 
    onLoadList(); 
    Adapter_Quisioner adapter_Quisioner = new Adapter_Quisioner(getActivity(), listQuisioner, lisLabelQues); 
    if(list_tt.getCount()!=listQuisioner.size()){ 
    list_tt.setAdapter(adapter_Quisioner); 
    } 
    return kuisioner; 
    }

此代碼爲集我的適配器：

public class Adapter_Quisioner extends BaseAdapter{ 
    Context context; 
    int count; 
    ArrayList <ModelListQues>listQuisioner; 
    ArrayList <ModelLabelQues>lisLabelQues; 

    public Adapter_Quisioner(Context context, ArrayList <ModelListQues>listQuisioner, ArrayList <ModelLabelQues>lisLabelQues){ 
     this.context = context; 
     this.listQuisioner = listQuisioner; 
     this.lisLabelQues = lisLabelQues; 
     this.count=listQuisioner.size(); 
    } 

    @Override 
    public int getCount() { 

     return count; 
    } 
    @Override 
    public int getViewTypeCount() { 
     return count; 
    } 

    @Override

    } 

}

那麼我的代碼有什麼問題嗎？我希望有人能幫助我。謝謝。

其中之一，你沒有正確使用ViewHolder模式。你應該在ViewHolder中執行findViewById（），而不是在適配器的getView（）方法中執行。除此之外，您只是因視圖回收問題而苦惱......請參閱下面的答案。 – 2014-10-03 02:49:58

if(view == null){ 

## don't make any view GONE here 

}else{ 

} 
## Play with visibility or GONE for every view here.This will solve your problem 

holder.option_label_y_tt3.setVisibility(View.GONE); 
holder.option_label_y_tt2.setVisibility(View.GONE); 
holder.option_label_y_tt1.setVisibility(View.GONE); and more... 

Then rest of your code
