在OnbindViewHolder中膨胀视图

Question

I am trying to inflate the custom layout inside the OnBindViewHolder of recyclerview. I could inflate the layout and add the view with for loop successfully to the LinearLayout which is the viewgroup of recyclerview's item, but I cannot set the values to the TextViews of the inflated layout. Here is what I tried so far.Any small hint would be helpful.

@Override
public void onBindViewHolder(ParentViewHolder holder, int position) {

    holder.title.setText(dataModels.get(position).getTopic());

    listModels = dataModels.get(position).getBreakingAndLatestNewsListModels();

    View.OnClickListener myListener = new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            String tag = (String) v.getTag();
            Toast.makeText(context, listModels.get(Integer.parseInt(tag)).getTitle(), Toast.LENGTH_SHORT).show();
        }
    };

    for (int i = 0; i < listModels.size(); i++) {
        View v = inflater.inflate(R.layout.news_content_layout, holder.containerLayout, false);
        v.setTag(i + "");
        holder.containerLayout.addView(v);
        v.setOnClickListener(myListener);

        TextView titleTextView = (TextView) v.findViewById(R.id.news_title_text_view);
        titleTextView.setText("jst testing");

    }


}

The alternate way I tried this too, but again there is another ploblem in expanding and collapsing the toolbar

Answer 1

I would read up on Expand a RecyclerView . There is an SO post @ Expandable list with RecyclerView? .

I don't know much about it. The idea is you want to expand/collapse from the top items in RecyclerView. The webpage above uses animation for expanding/collapsing of items.

Answer 2

If you want a vericlally scroll recycler view inside a recycler view item then it is not possible as i know, Because there will be a scrolling conflict and app going to crash in that case, You can use Horizontally scrolled recycler view inside a vertically scrolled recycler view. I suggest you to go for Linear Layout if you want to achieve the behavior which you are trying to implement.
