Answer 1

You Should do this in onBindViewHolder() method (using RecyclerView)

class YourAdapter

String searchString="";

@Override
    public void onBindViewHolder(AllMessageAdapter.DataObjectHolder holder, final int position) {

        holder.message.setText(mDataset.get(position).Message);

        AllMessageList.Message message=mDataset.get(position);

        String name = message.Message.toLowerCase(Locale.getDefault());

        if (name.contains(searchString)) {

            int startPos = name.indexOf(searchString);
            int endPos = startPos + searchString.length();

            Spannable spanString = Spannable.Factory.getInstance().newSpannable(holder.message.getText());
            spanString.setSpan(new ForegroundColorSpan(Color.RED), startPos, endPos, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

            holder.message.setText(spanString);
        }

    }

Your Filter(in Adapter)

public void setFilter(ArrayList countryModels,String searchString) {
        this.searchString=searchString;
        mDataset = new ArrayList<>();
        mDataset.addAll(countryModels);
        notifyDataSetChanged();
    }
