如何从 listview getview 方法中的 POJO 类中删除对象

Question

在我的列表视图中，当用户单击复选框时，我有复选框，然后值将添加到数组列表（POJO 类）中，问题是当用户取消选中复选框时，必须立即从列表中删除值它没有发生，请建议我

这是我的适配器类

public class MyComposeListItemAdapter extends ArrayAdapter {

public Context mContext;
int row;
public List<MyComposeObject> arrayList;     
public ImageLoader imageLoader;     
private static LayoutInflater inflater=null;    

public static List<SelectedFriendsObject> selectedfriends = new ArrayList<SelectedFriendsObject>();
SelectedFriendsObject friendsObject=new SelectedFriendsObject();

public MyComposeListItemAdapter(Context context, int resource) {
    super(context, resource);
    // TODO Auto-generated constructor stub

    this.mContext = context;
    this.row = resource;
    arrayList = (ArrayList<MyComposeObject>) Woosuite_Login.composeObjectslist;
//  System.out.println("arrayList2"+arrayList.size());      
    imageLoader=new ImageLoader(context);       

}   
@Override
public Context getContext() {
    // TODO Auto-generated method stub
    return mContext;
}
@Override
public int getCount() {
    // TODO Auto-generated method stub
    return arrayList.size();
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub
    ViewHolder holder;

    if (convertView == null) {
        LayoutInflater inflater = (LayoutInflater) mContext
                .getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
        convertView = inflater.inflate(row, null);
        holder = new ViewHolder();
        convertView.setTag(holder);
    } else
        holder = (ViewHolder) convertView.getTag();

    holder.checkBox=(CheckBox) convertView.findViewById(R.id.checkBox666);

        holder.checkBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {

            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                // TODO Auto-generated method stub

                if(isChecked){                                                                  
                    itemChecked.set(position, true);

                        friendsObject.setProfile_type(arrayList.get(position).getCom_profileType());
                        friendsObject.setSelected_id(arrayList.get(position).getCom_profileId());
                        selectedfriends.add(friendsObject);

                }else{

                    // when ever control comes here i need to remove the values contained in that list, 

                }
            }
        });     

    return convertView;
}

private static class ViewHolder {
    CheckBox checkBox;
}

}

在 holder.checkBox.setOnCheckedChangeListener 的 else 部分，您可以从 arraylist 中删除该项目，然后使用。

adapterObj.notifyDataSetChanged();
