Upload 문장선택

• 선택한 감정에 대한 3가지 문장을 보여주는 뷰. 해당 날짜와 앞서 선택한 감정을 보여줌.

• Recycler 뷰를 사용한 버튼 구현

recycler뷰의 아이템으로 들어갈 xml, adapter, ViewHolder,data

data파일

data class UploadSentenceData(
        val author:String,
        val book:String,
        val publisher:String,
        val sentence:String
)

adapter

class UploadSentenceAdapter (private val context: Context) : RecyclerView.Adapter<UploadSentenceViewHolder>(){
    var data= mutableListOf<UploadSentenceData>()
    private lateinit var binding: ActivityUploadSentenceBinding//뷰바인딩

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): UploadSentenceViewHolder {
        var view=LayoutInflater.from(context).inflate(R.layout.layout_select_sentence_card,parent,false)
        return UploadSentenceViewHolder(view)
    }

    override fun getItemCount(): Int {
        return data.size //ppt에서 :Int =data.size랑 같은 의미. 줄일수 있음.
    }
    override fun onBindViewHolder(holder: UploadSentenceViewHolder, position: Int) {
        holder.onBind(data[position])
        holder.itemView.setOnClickListener{
            itemClickListener.onClickItem(it,position)
        }
    }

    //클릭리스너 선언
    private lateinit var itemClickListener: ItemClickListener

    //클릭리스너 등록 메소드
    fun setItemClickListener(itemClickListener: ItemClickListener) {
        this.itemClickListener = itemClickListener
    }
}

ViewHolder

class UploadSentenceViewHolder (itemView:View):RecyclerView.ViewHolder(itemView){//val,var하면 선언과 동시에 초기화.

    private val author:TextView=itemView.findViewById(R.id.tv_author)
    private val book:TextView=itemView.findViewById(R.id.tv_book)
    private val publisher:TextView=itemView.findViewById(R.id.tv_publisher)
    private val sentence:TextView=itemView.findViewById(R.id.tv_sentence)
    private val cardview:ConstraintLayout=itemView.findViewById(R.id.cardview)

    fun onBind(data: UploadSentenceData) {//sampledata.kt가 객체로 들어오게됨.
        author.text = data.author
        book.text = data.book
        publisher.text = data.publisher
        sentence.text = data.sentence
    }

}

• Lottie 사용

build.gradle

dependencies {
  implementation 'com.airbnb.android:lottie:$lottieVersion'
}

xml

<com.airbnb.lottie.LottieAnimationView
    android:id="@+id/lottie"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:adjustViewBounds="true"
    android:scaleType="centerCrop"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    app:lottie_autoPlay="true"
    app:lottie_fileName="UploadSentenceCircle.json"
    app:lottie_loop="false" />

• Companion 을 사용해 UploadSentence에서 UploadSentence, Feeling 모두 종료

  UploadFeeling.kt

  companion object {
      var activity : Activity? = null
  }
  

  UploadSentence.kt

  //X 버튼
  binding.imgClose.setOnClickListener {
      //Upload 들어오기 전화면 보여주기
      UploadFeelingActivity.activity?.finish()
      finish()
  }
