Android 如何启用和禁用每个列表项上的图像按钮单击“惰性适配器”

在ListView中选择项目时出现问题，单击每个列表项目上我试图启用的按钮。按钮我想使选择模式单一，即使在xml中实现选择模式单一。它允许我选择多个ImageButton。我想在这里实现的是，一次只有用户可以选择一个ListView项目，但在这里ImageButton保持单击状态以进行ListView的多个选择。 有人能帮我解决这个问题吗

public class LazyAdapter extends BaseAdapter{

private Activity activity;
private String[] data;
private String[] imageNames;
private String[] creatives;
private static LayoutInflater inflater=null;
public ImageLoader imageLoader; 
public String assetId;
public LinearLayout creativeSaveChanges,cancelCreative;

public LazyAdapter(Activity a, String[] imageurl,String[] names,String[] creativeId) {
    activity = a;
    data=imageurl;
    imageNames = names;
    creatives = creativeId;
    inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    imageLoader=new ImageLoader(activity.getApplicationContext());
}

public int getCount() {
    return data.length;
}

public Object getItem(int position) {
    return position;
}

public long getItemId(int position) {
    return position;
}

public View getView(final int position, View convertView, ViewGroup parent) {
    View vi=convertView;
    if(convertView==null)
        vi = inflater.inflate(R.layout.boards_creative_custom_listview, null);

    cancelCreative = (LinearLayout)vi. findViewById(R.id.cancelCreative);
    creativeSaveChanges = (LinearLayout)vi. findViewById(R.id.creativeSaveChanges);


    TextView text=(TextView)vi.findViewById(R.id.specialTxtFridaySpecialTroopsList);;
    ImageView image=(ImageView)vi.findViewById(R.id.imageboardsCreativeList);
    final ImageButton selectbutton = (ImageButton) vi.findViewById(R.id.imageButtonRefreshListCreative);
    text.setText(imageNames[position]);
    imageLoader.DisplayImage(data[position], image);

     vi.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub


            selectbutton.setBackgroundResource(R.drawable.rightblue);
             assetId = creatives[position];
            Log.e("creatives", assetId);

              for (int i = 0; i <creatives.length; i++) {
               if(i == position){
                    Log.e("creatives.length", i+" ,"+position+"");
               }else if(i != position){
                    selectbutton.setVisibility(View.GONE);
                    Log.e("creatives.length", i+" and "+position+"");
               }
            }
        }
    });

    return vi;
}


}

我找到了答案，我想感谢shaiful回答的以下链接帮助我找到了答案。

image.setenablefalse或image.setenabletrueNope不能以这种方式工作，因为我们正在尝试单击每个列表项。假设我单击了列表项1按钮应启用，单击列表项2时，项目1按钮应禁用，并在项目2中启用。单击列表视图项时使用值true或false单击使用notifidatachange更新您的列表视图更改可能是其逻辑井其惰性适配器配合，无法调用项单击。我们可以在vi.onclicklistener.com中实现的唯一一件事是向延迟适配器传递一个参数集，如true或false数组，并在单击listview并重新加载listview时更新其值
