  android:textColor="@color/black"

  app:expandBtnText="확장"
  app:btnColor="@color/purple_500"
  app:btnSize="15sp"
  app:colMaxLines="2"
  app:originalText="원하는 텍스트를 넣어주세요 :)"
  />

collapseBtnText

ReadMoreView 내에 표시되는 '축소' 기능 버튼의 String을 정의합니다. 단, 빈 String 을 입력하는 경우 표시되지 않습니다. 기본값은 '닫기' 입니다.

  app:collapseBtnText="축소"

expandBtnText

ReadMoreView 내에 표시되는 '확장' 기능 버튼의 String을 정의합니다. 단, 빈 String 을 입력하는 경우 표시되지 않습니다. 기본값은 '기더보기' 입니다.

  app:expandBtnText="확장"

btnColor

ReadMoreView 내에 표시되는 '축소', '확장' 기능 버튼의 color를 정의합니다. 기본값은 Color.Black 입니다.

  app:btnColor="@color/black"

btnSize

ReadMoreView 내에 표시되는 '축소', '확장' 기능 버튼의 size를 정의합니다.

  app:btnSize="15sp"

colMaxLines

ReadMoreView 축소 상태시 최대 라인 수를 정의합니다. 기본값은 Int.MAX_VALUE 입니다.

  app:colMaxLines="2"

originalText

ReadMoreView 에 표시될 String 전문을 정의합니다. collapse 상태인 경우 colMaxLines 속성 값에 따라 최대 라인 수 만큼만 표시됩니다. expanded 상태인 경우 String 전문이 표시됩니다.

  app:originalText="원하는 텍스트를 넣어주세요 :)"

클래스 필드 및 메서드

originalText

ReadMoreView 에 표시될 String 전문을 정의합니다. xml 속성 originalText 와 동일합니다.

  readMoreView.originalText = "원하는 텍스트를 넣어주세요 :)"

isExpanded

ReadMoreView 의 '확장' 상태 여부를 반환합니다. (Boolean)

  readMoreView.isExpanded == true

isCollapsed

ReadMoreView 의 '축소' 상태 여부를 반환합니다. (Boolean)

  readMoreView.isCollapsed == true

expand()

ReadMoreView 의 상태를 '확장' 으로 변경합니다. 이미 확장 상태인 경우 동작하지 않습니다.

  readMoreView.expand()

collapse()

ReadMoreView 의 상태를 '축소' 로 변경합니다. 이미 축소 상태인 경우 동작하지 않습니다.

  readMoreView.collapse()

toggle()

ReadMoreView 의 상태를 '반전' 시킵니다.

  readMoreView.toggle()

setStateChangedListener(listener: ((isExpanded: Boolean) -> Unit)?)

ReadMoreView 의 확장/축소 상태 변경 callback 을 설정합니다. callback 함수는 확장 상태는 true, 축소 상태로 변경되는 경우 false 가 인자로 인입됩니다.

  readMoreView.setStateChangedLisftener { isExpanded ->
    if (isExpanded) {
      // 필요한 동작
    }
  }

setExpandableChangedListener(listener: ((isExpandable: Boolean) -> Unit?))

ReadMoreView 가 조건을 만족하여 확장/축소 가능 여부 변경 callback 을 설정합니다. 원본 String(originalText) 가 View 의 너비에 맞춰 표현될때, 최대 라인 수 (colMaxLines) 를 넘어서는 경우 callback 함수의 인자로 true 가 인입됩니다.

  readMoreView.setExpandableChangedListener { isExpandable ->
    if (isExpandable) {
      // 필요한 동작
    }
  }
