Question

我有一个ListView用于在我的申请中显示一些问题。在我滚动之前第一次显示ListView时，一切看起来都是正确的，直到我向下滚动并向上滚动ListView，我的ListView列表中的几个视图如下所示：

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

我不知道为什么会发生这种情况ListView，我搜索了很多解决方案，但它似乎并没有真正帮助我，这是我调用我的适配器的代码：

@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;
    }

此代码用于设置我的适配器：

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
    public Object getItem(int position) {

        return listQuisioner.get(position);
    }

    @Override
    public long getItemId(int arg0) {

        return 0;
    }

    @Override

}

我的代码中有什么问题吗？我希望有人可以帮助我。谢谢。

Answer 1

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

滚动后的ListView错误
