   .build().apply {
   	addShowMoreLess(textView = tv_first, text = tv_first.text, isContentExpanded = true)
        setListener(object : ShowMoreLess.OnShowMoreLessClickedListener {

             override fun onShowMoreClicked() {
             	//We can handle or save show more state
             }

             override fun onShowLessClicked() {
             	//We can handle or save show less state
             }
   	}
   )
}

Customization

You can customize things like bellow

1. Can change textLengthAndLengthType as

.textLengthAndLengthType(
     length = 100,//Length where to add show more text
     textLengthType = ShowMoreLess.TYPE_CHARACTER //textLengthType is TYPE_CHARACTER
)
    and
.textLengthAndLengthType(
     length = 5,//Line of text view where to add show more text
     textLengthType = ShowMoreLess.TYPE_LINE //textLengthType is TYPE_LINE
)

2. Can change show more and show less text label as

.showMoreLabel("read more")
.showLessLabel("read less")

3. Can change text color of Show more or Show less

.showMoreLabelColor(Color.parseColor("#ffffff"))
.showLessLabelColor(Color.parseColor("#ffffff"))

4. Can enable labelUnderLine easily as

.labelUnderLine(labelUnderLine = false)//true for underline and false for not underline

5. Can enable labelBold easily as

.labelBold(labelBold = false)//true for bold and false for normal

6. Can easily handle expand and collapse animation by

.expandAnimation(expandAnimation = true)//expandAnimation will affect both expand and collapse logic

7. Can handle textClickable except clicking more or less txt for expand and collapse

.textClickable(
     textClickableInExpand = true,//It will enable text clickable in expand mode
     textClickableInCollapse = true//It will enable text clickable in collapse mode
)

8. Can handle enableLinkify() will linkifies WEB_URLS, EMAIL_ADDRESSES, PHONE_NUMBERS and MAP_ADDRESSES

.enableLinkify(linkify = true)//If linkify = true then should disable point no 7.textClickable to work

9. addShowMoreLess() function will handle text expand or collapse state

addShowMoreLess(
     textView = tv_first, //It is a text view where we have to add read more or less
     text = tv_first.text, //String in textview
     isContentExpanded = true//Content expand or collapse history
)

10. At last setListener() function for callbacks

setListener(object : ShowMoreLess.OnShowMoreLessClickedListener {

     override fun onShowMoreClicked() {
     	//We can handle or save show more state
     	//This sate will send in no 7.addShowMoreLess() function of isContentExpanded = false / true
     }

     override fun onShowLessClicked() {
     	//We can handle or save show less state
     	//This sate will send in no 7.addShowMoreLess() function of isContentExpanded = false / true
     }
}
