如何在 android Kotlin 中創建合並適配器 class

我有兩個 class 一個 class 包含 header 其他 class 包含圖像卡 如何在 kotlin 中創建合並適配器 class

電影卡適配器

class MovieCardAdapter (private var image:IntArray):RecyclerView.Adapter<MovieCardAdapter.CardViewHolder>(){


override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): CardViewHolder {
    val itemView = LayoutInflater.from(parent.context).inflate(R.layout.movie_cardview,parent,false)

    return CardViewHolder(itemView)
}

override fun onBindViewHolder(holder: CardViewHolder, position: Int) {
    holder.movieImage.setImageResource(image[position])
    holder.movieImage.setOnClickListener { view ->
        val intent = Intent(view.context, MovieDetailsActivity::class.java)
        intent.putExtra("samples",image[position] )
        view.context.startActivity(intent)
    }
}

override fun getItemCount(): Int {
    return image.size
}

class CardViewHolder(itemView: View) :RecyclerView.ViewHolder(itemView){
    val movieImage : ImageView = itemView.findViewById(R.id.movieImage)
    val numberOfTrailer : TextView = itemView.findViewById(R.id.number_of_trailer)
} }

Header 適配器

class HeaderAdapter(private var section:String): RecyclerView.Adapter<HeaderAdapter.HeaderViewHolder>(){
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): HeaderViewHolder {
    val view = LayoutInflater.from(parent.context)
        .inflate(R.layout.headerview, parent, false)
    return HeaderViewHolder(view)
}

override fun onBindViewHolder(holder: HeaderViewHolder, position: Int) {
    holder.headerTxt.text = section
    holder.headerLayout.setOnClickListener { view ->
        val intent = Intent(view.context, GridLayoutDisplayActivity::class.java)
        intent.putExtra("samples", section )
        view.context.startActivity(intent)
    }
}

override fun getItemCount() = 1

class HeaderViewHolder(view: View) : RecyclerView.ViewHolder(view){
     val headerTxt: TextView = itemView.findViewById(R.id.headerTxt)
     val headerLayout: View = itemView.findViewById(R.id.section_click)
} }

分段

val movieCardAdapter = MovieCardAdapter(image)
    val headerAdapter = HeaderAdapter("On Web")
    binding.imageCardRecycleview.adapter = headerAdapter

Answer 1

您可以在此處使用 ConcatAdapter。 您可以查看我的回購作為示例。

Answer 2

其他解決方案：

您可以通過在一項活動中聲明 2 個適配器來簡單地執行此操作。

將兩個recyclerview放在嵌套scrollview中。 並通過添加此代碼（對於兩個recylerview ）停止recyclerview滾動。

val myLinearLayoutManager = object : LinearLayoutManager(this) {
    override fun canScrollVertically(): Boolean {
        return false
    }
}

recyclerview !!.layoutManager = myLinearLayoutManager
