lineCount in recyclerView example

[eggham0518]

It's working well.

   `   TextView   tv_content = holder.tv_content;

       tv_content.setText(strContent);

         tv_content.post(new Runnable() {
            @Override
            public void run() {
                int lineCount = tv_content.getLineCount();

                if (lineCount < 4) {
                    return;
                }

                int start = tv_content.getLayout().getLineStart(0);
                int end = tv_content.getLayout().getLineEnd(2);

                int lmitLength;
                
                try {
                    lmitLength = strContent.substring(start, end).length() - 2;
                } catch (Exception e) {
                    return;
                }
                
                if (lmitLength < 0) {
                    return;
                }
                
                CustomReadMoreOption readMoreOption = new CustomReadMoreOption.Builder(mContext)
                        .textLength(lmitLength, ReadMoreOption.TYPE_CHARACTER)
                        .moreLabel("more")
                        .lessLabel("less")
                        .build();

                readMoreOption.addReadMoreTo(tv_content, strContent);

            }
        });``
