Android RecyclerView addition & removal of items

I have done something similar.In your MyAdapter:

public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{    public CardView mCardView;    public TextView mTextViewTitle;    public TextView mTextViewContent;    public ImageView mImageViewContentPic;    public ImageView imgViewRemoveIcon;    public ViewHolder(View v) {        super(v);        mCardView = (CardView) v.findViewById(R.id.card_view);        mTextViewTitle = (TextView) v.findViewById(R.id.item_title);        mTextViewContent = (TextView) v.findViewById(R.id.item_content);        mImageViewContentPic = (ImageView) v.findViewById(R.id.item_content_pic);        //......        imgViewRemoveIcon = (ImageView) v.findViewById(R.id.remove_icon);        mTextViewContent.setOnClickListener(this);        imgViewRemoveIcon.setOnClickListener(this);        v.setOnClickListener(this);        mTextViewContent.setOnLongClickListener(new View.OnLongClickListener() {            @Override            public boolean onLongClick(View view) {                if (mItemClickListener != null) {                    mItemClickListener.onItemClick(view, getPosition());                }                return false;            }        });    }    @Override    public void onClick(View v) {        //Log.d("View: ", v.toString());        //Toast.makeText(v.getContext(), mTextViewTitle.getText() + " position = " + getPosition(), Toast.LENGTH_SHORT).show();        if(v.equals(imgViewRemoveIcon)){            removeAt(getPosition());        }else if (mItemClickListener != null) {            mItemClickListener.onItemClick(v, getPosition());        }    }}public void setOnItemClickListener(final OnItemClickListener mItemClickListener) {    this.mItemClickListener = mItemClickListener;}public void removeAt(int position) {    mDataset.remove(position);    notifyItemRemoved(position);    notifyItemRangeChanged(position, mDataSet.size());}

Hope this helps.

Edit:

getPosition() is deprecated now, use getAdapterPosition() instead.

first of all, item should be removed from the list!

  mDataSet.remove(getAdapterPosition());

then:

  notifyItemRemoved(getAdapterPosition());  notifyItemRangeChanged(getAdapterPosition(),mDataSet.size());

if still item not removed use this magic method :)

private void deleteItem(int position) {        mDataSet.remove(position);        notifyItemRemoved(position);        notifyItemRangeChanged(position, mDataSet.size());        holder.itemView.setVisibility(View.GONE);}

Kotlin version

private fun deleteItem(position: Int) {    mDataSet.removeAt(position)    notifyItemRemoved(position)    notifyItemRangeChanged(position, mDataSet.size)    holder.itemView.visibility = View.GONE}
