从嵌套的RecyclerView获取Clicked View和位置

Question

我试图在recyclerview中显示meesages。

消息2

attachement-1

Messge-3（没有附件）

如果行有附件，我会创建一个新的Recyclerview。点击监听器不适用于RecyclerView ，侦听器适用于除RecyclerView之外的所有其他视图元素。< / p>

MsgCursorAdapter

    }

 public static class ViewHolder_Type1 extends RecyclerView.ViewHolder  implements View.OnClickListener{

        public TextView mymessageTextView, mytimeTextView;
        public RecyclerView attachments_list;
        public ViewHolder_Type1(View v) {
            super(v);

  public static class ViewHolder_Type2 extends RecyclerView.ViewHolder implements View.OnClickListener {
        public TextView messageTextView, timeTextView;
        public RecyclerView attachments_list;

    {
        public void itemClicked(View v, int position);

    }

PostAttachmentAdapter

public class PostAttachmentAdapter扩展了RecyclerView.Adapter {

private Context mContext;
private ArrayList<PostAttachment> mAttachmentsArray;
private String postCloumnid;
public PostAttachmentAdapter(ArrayList<PostAttachment> attachmentsArray,Context context,String postColumnId)
{
    this.mContext=context;
    this.mAttachmentsArray=attachmentsArray;
    this.postCloumnid=postColumnId;

}

@Override
public PostAttachmentAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    final View itemLayoutView = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.post_attachment_image,null);

    final ViewHolder viewHolder = new ViewHolder(itemLayoutView);
    return viewHolder;
}

@Override
public void onBindViewHolder(ViewHolder holder, int position) {
    File f = new File(mAttachmentsArray.get(position).getFileName());
    String filename = "Thumb_"+f.getName();
    if (FileUtility.getMimeType(filename).startsWith("image/")) {
        String targetPath= Util.getAttachmentPathForUser(Integer.toString(CurrentUser.getInstance().getId()),postCloumnid, filename);

        File thumb=new File(targetPath);
        if (thumb.exists()) {
            Bitmap myBitmap = BitmapFactory.decodeFile(targetPath);
            myBitmap = Bitmap.createScaledBitmap(myBitmap,250,250,true);
            myBitmap= ImageUtility.fastblur(myBitmap,0.4f,7);
            holder.imgViewIcon.setImageBitmap(myBitmap);
        }
        else {
            holder.imgViewIcon.setImageResource(R.drawable.ic_photo_black_48dp);
        }
    }
    else {
        holder.imgViewIcon.setImageResource(R.drawable.ic_insert_drive_file_black_48dp);
    }

}

@Override
public int getItemCount() {
    return mAttachmentsArray.size();
}


public static class ViewHolder extends RecyclerView.ViewHolder {

    public TextView txtViewTitle;
    public ImageView imgViewIcon;

    public ViewHolder(View itemLayoutView) {
        super(itemLayoutView);
        imgViewIcon = (ImageView) itemLayoutView.findViewById(R.id.post_attachment);
    }

}
