我正在尝试膨胀并将我的数据绑定(bind)到我的 ViewHolder。每当我绑定(bind)时我都会遇到这个错误:

我以前从未遇到过这个错误。关于此的信息也不多。发生这种情况的任何原因？

编辑

我认为问题出在这段代码上:

public class ProfileAdapter extends RecyclerView.Adapter<TypedHolder>
{
    public static final int TYPE_HEADER = 0;
    public static final int TYPE_MAP = 1;

    private List<GeoMap> mGeoMaps = new ArrayList<>();
    private Context mContext;
    private User mCurrentUser;

    private ProfileHeaderHolderInterface mProfileHeaderHolder;
    private DownloadedMapHolderInterface mDownloadedMapHolder;

    private ProfileHeaderHolderInterface.Listener mProfileHeaderHolderInterfaceListener;
    private DownloadedMapHolderInterface.Listener mDownloadedMapHolderInterfaceListener;

    private ProfileHeaderHolderInterface.OnBind mProfileHeaderHolderInterfaceOnBind;
    private DownloadedMapHolderInterface.OnBind mDownloadedMapHolderInterfaceOnBind;


    public ProfileAdapter(Context context)
    {
        mContext = context;

        mProfileHeaderHolder = new ProfileHeaderHolder(mContext);
        mDownloadedMapHolder = new DownloadedMapHolder(mContext);
    }

    public void setContent(List<GeoMap> map, User user)
    {
        if(map == null)
            return;

        mGeoMaps.clear();
        mGeoMaps.addAll(map);

        mCurrentUser = user;
    }

    public ProfileHeaderHolderInterface getProfileHeaderView()
    {
        return mProfileHeaderHolder;
    }

    @Override
    public TypedHolder onCreateViewHolder(ViewGroup parent, int viewType)
    {
        LayoutInflater inflater = LayoutInflater.from(mContext);

        switch(viewType)
        {
            case TYPE_HEADER:
                return mProfileHeaderHolder.createHolder(parent);
            case TYPE_MAP:
            {
                View view = inflater.inflate(R.layout.listitem_offline_map, parent, false);
                DownloadedMapHolder.ViewHolder holder = new DownloadedMapHolder.ViewHolder(view);
                // return mDownloadedMapHolder.createHolder(parent);
                return holder;
            }
        }

        return new TypedHolder(new View(mContext), -1);
    }

    @Override
    public int getItemViewType(int position)
    {
        if(position == 0)
            return TYPE_HEADER;

        return TYPE_MAP;
    }

    @Override
    public void onBindViewHolder(TypedHolder holder, int position)
    {
        switch(holder.getType())
        {
            case ProfileAdapter.TYPE_HEADER:
                if(mProfileHeaderHolderInterfaceListener != null)
                    mProfileHeaderHolderInterfaceOnBind.onBind(holder, mCurrentUser);
                break;

            case ProfileAdapter.TYPE_MAP:
                {
                    GeoMap geoMap = mGeoMaps.isEmpty()? null : mGeoMaps.get(position - 1);

                    //if (mDownloadedMapHolderInterfaceListener != null)
                    //    mDownloadedMapHolderInterfaceOnBind.onBind(holder, geoMap, position - 1);

                    DownloadedMapHolder.ViewHolder downloadedMapHolder = (DownloadedMapHolder.ViewHolder) holder;
                    downloadedMapHolder.mTextViewLocation.setText(geoMap.getMapLocation());
                    downloadedMapHolder.mTextViewLocation.setText(geoMap.getDateString());
                }
                break;
        }
    }

    @Override
    public int getItemCount()
    {
        return mGeoMaps.isEmpty()? 1 : mGeoMaps.size() + 1;
    }

    public void setProfileHeaderHolderInterfaceListener(ProfileHeaderHolderInterface.Listener listener)
    {
        mProfileHeaderHolderInterfaceListener = listener;
        mProfileHeaderHolder.setProfileHeaderHolderInterfaceListener(listener);
    }

    public void setDownloadedMapHolderInterfaceListener(DownloadedMapHolderInterface.Listener listener)
    {
        mDownloadedMapHolderInterfaceListener = listener;
        mDownloadedMapHolder.setDownloadedMapHolderInterfaceListener(listener);
    }

    public void setProfileHeaderHolderInterfaceOnBind(ProfileHeaderHolderInterface.OnBind onBind)
    {
        mProfileHeaderHolderInterfaceOnBind = onBind;
    }

    public void setDownloadedMapHolderInterfaceOnBind(DownloadedMapHolderInterface.OnBind onBind)
    {
        mDownloadedMapHolderInterfaceOnBind = onBind;
    }
}

这个问题非常令人沮丧。在我只用一些必需品剥离我的适配器后，我能够弄清楚它是在这条线上出现的:

@Override
public int getItemViewType(int position)
{
    if(position == 0)
        return TYPE_HEADER;

    else if(position > 0 && position < mGeoMaps.size())
        return TYPE_MAP;
    else
    {
        Log.i(ShoreLeaveApplication.TAG, "CANNOT BIND on TYPE -1!!!!");
        return -1;
    }
}

我试图创建一个非常简单的回收器 View ，其中有一个添加记事卡始终作为我列表的顶部和第一个元素(类似于 FB)。剩下的只是 map 选择。这会导致我的 onCreateViewHolder 收到无效的 id 并膨胀错误的布局。当它到达最后一项时会发生这种情况。这是我匆忙写的蹩脚代码并用这个替换它:

@Override
public int getItemViewType(int position)
{
    if(position == 0) // first item is always the header
        return TYPE_HEADER;

    // the rest is a normal item
    return TYPE_MAP;
}

现在可以了。

谢谢!
