如何在不同的按钮点击时连接到不同的 API？

Question

** 我已经在这些 6 个项目上放置了按钮，现在我只需要当用户点击按钮时，它必须连接到 API 获取并显示内容。同样地，单击其他所有按钮都应连接到各自的 API。现在创建新活动和新适配器对于每个项目都是冗余代码，请告诉我如何正确实现这一点 **

home fragment

class Homefragment : Fragment() {

 lateinit var buttondept:Button

override fun onCreateView(
    inflater: LayoutInflater, container: ViewGroup?,
    savedInstanceState: Bundle?
): View? {
    // 加载该片段的布局
    val view= inflater.inflate(R.layout.fragment_homefragment, container, false)
       buttondept=view.findViewById(R.id.btnDept)
       buttondept.setOnClickListener {
           val intent=Intent(context,descactivity::class.java)
           intent.putExtra("option","department")
           startActivity(intent)
       }

    return view

}

}

desc activity

class descactivity : AppCompatActivity() {
lateinit var recyclerDashBoard: RecyclerView
lateinit var layoutmanager: RecyclerView.LayoutManager

lateinit var recyclerAdapter:Horizontal_RecyclerView
lateinit var progressLayout: RelativeLayout
lateinit var progressBar: ProgressBar
lateinit var button: Button
override fun onCreate(savedInstanceState: Bundle?) {

    recyclerDashBoard = findViewById(R.id.recyclerDashboard)

    progressBar = findViewById(R.id.progressbar)

    progressLayout = findViewById(R.id.progresslayout)
    progressLayout.visibility = View.VISIBLE

         val intent=getIntent()
         val selectionOption= intent.getStringExtra("option")

                        val success = it.getBoolean("success")
                        if (success) {
