【问题描述】：

我有一个带有 2 个元素的回收站视图。我想添加 2 个按钮来做不同的事情（取决于回收站视图的哪个元素。怎么可能做到这一点？我的元素是 textviews

SettingsActiv.kt

class SettingsActiv : AppCompatActivity() 

    override fun onCreate(savedInstanceState: Bundle?) 
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_settings)

        val arrow_backBtn = findViewById(R.id.settingsToolbarBtn) as Button
        arrow_backBtn.setOnClickListener
            startActivity(Intent(this, MainActivity::class.java))
        

        val linearLayout  = findViewById(R.id.constr) as LinearLayout
        val recyclerView =  RecyclerView(this)
        val series = ArrayList<SeriesModel>()
        recyclerView.layoutParams = LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT)
        series.add(SeriesModel("Unit of length","Meter"))
        series.add(SeriesModel("Unit of temperature","Celcius"))
        val adapter = MyAdapter(series)
        recyclerView.setHasFixedSize(true)
        recyclerView.layoutManager = LinearLayoutManager(this, LinearLayout.VERTICAL, false)
        recyclerView.adapter = adapter
        linearLayout.addView(recyclerView,1)

MyAdapter.kt

class MyAdapter(private val seriesList: ArrayList<SeriesModel>) : RecyclerView.Adapter<MyAdapter.MyViewHolder>() 


    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MyAdapter.MyViewHolder 
        val v = LayoutInflater.from(parent.context).inflate(R.layout.activity_settings_child, parent, false)
        return MyViewHolder(v)
    

    override fun onBindViewHolder(holder: MyViewHolder, position: Int) 
        holder.textViewName.text = seriesList[position].name
        holder.textViewNameDesc.text = seriesList[position].desc

    

    override fun getItemCount(): Int 
        return seriesList.size
    

    class MyViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) 
        val textViewName = itemView.findViewById(R.id.name) as TextView
        val textViewNameDesc = itemView.findViewById(R.id.desc) as TextView

    

【参考方案1】：

试试这个

 override fun onBindViewHolder(holder: MyViewHolder, position: Int) 
        holder.textViewName.text = seriesList[position].name
        holder.textViewNameDesc.text = seriesList[position].desc

        holder.textViewName.setOnClickListener 
            Toast.makeText(context,"clicked",Toast.LENGTH_SHORT).show()
