You can use below code for this;

 holder.tvMoreInfo.setText(horizontalList.get(position));

        holder.tvMoreInfo.post(new Runnable() {
            @Override
            public void run() {
                int lineCount = holder.tvMoreInfo.getLineCount();
                if (lineCount<3)
                {

                }else
                {
                    makeTextViewResizable(holder.tvMoreInfo, 3, "...More", true);
                }
            }
        });



 public static void makeTextViewResizable(final TextView tv, final int maxLine, final String expandText, final boolean viewMore) {

    if (tv.getTag() == null) {
        tv.setTag(tv.getText());
    }
    ViewTreeObserver vto = tv.getViewTreeObserver();
    vto.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {

        @SuppressWarnings("deprecation")
        @Override
        public void onGlobalLayout() {
            String text;
            int lineEndIndex;
            ViewTreeObserver obs = tv.getViewTreeObserver();
            obs.removeGlobalOnLayoutListener(this);
            if (maxLine == 0) {
                lineEndIndex = tv.getLayout().getLineEnd(0);
                text = tv.getText().subSequence(0, lineEndIndex - expandText.length() + 1) + " " + "" + expandText + "";
            } else if (maxLine > 0 && tv.getLineCount() >= maxLine) {
                lineEndIndex = tv.getLayout().getLineEnd(maxLine - 1);
                text = tv.getText().subSequence(0, lineEndIndex - expandText.length() + 1) + " " + "" + expandText + "";
            } else {
                lineEndIndex = tv.getLayout().getLineEnd(tv.getLayout().getLineCount() - 1);
                text = tv.getText().subSequence(0, lineEndIndex) + " " + "" + expandText + "";
            }
            tv.setText(Html.fromHtml(text));
            tv.setMovementMethod(LinkMovementMethod.getInstance());

            tv.setText(
                    addClickablePartTextViewResizable(Html.fromHtml(tv.getText().toString()), tv, lineEndIndex, expandText,
                            viewMore), TextView.BufferType.SPANNABLE);
        }
    });
}

private static SpannableStringBuilder addClickablePartTextViewResizable(final Spanned strSpanned, final TextView tv,
                                                                        final int maxLine, final String spanableText, final boolean viewMore) {
    String str = strSpanned.toString();
    SpannableStringBuilder ssb = new SpannableStringBuilder(strSpanned);

    if (str.contains(spanableText)) {
        ssb.setSpan(new MySpannable(false) {

            @Override
            public void onClick(View widget) {
                tv.setLayoutParams(tv.getLayoutParams());
                tv.setText(tv.getTag().toString(), TextView.BufferType.SPANNABLE);
                tv.invalidate();
                if (viewMore) {
                    makeTextViewResizable(tv, -1, "...Less", false);
                } else {
                    makeTextViewResizable(tv, 3, "...More", true);
                }

            }
        }, str.indexOf(spanableText), str.indexOf(spanableText) + spanableText.length(), 0);

    }
    return ssb;
