activity在 Runnable 中如何工作我的 Android 表格未显示

我正在使用JSoup来解析一个网站(我不得不将其设置为使用明文请求，因为不支持HTTPS).它是在Runnable，以避免阻塞网络主线程.但是，当我运行我的代码时，它似乎不显示.我怀疑它与activity有关(因为我在设置它时遇到了问题)，并且我使用的是内部类，但没有返回任何错误或警告.我做错了什么？

package com.example.investmenthuntermobile


import android.os.Bundle
import android.util.Log
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import android.widget.TableRow
import android.widget.TextView
import androidx.fragment.app.Fragment
import com.example.investmenthuntermobile.databinding.InsiderFragmentBinding
import org.jsoup.Jsoup


class InsiderFragment : Fragment() {

    private lateinit var binding: InsiderFragmentBinding


    override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View {
        binding = InsiderFragmentBinding.inflate(layoutInflater)
        return binding.root
    }

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)

        setupData()

    }

    private fun setupData() {
        val thread = Thread(Task()).start()
    }


    inner class Task() : Runnable {

        override fun run() {
            val doc = Jsoup.connect("http://openinsider.com/search?q=GME").get()
            val table = doc.select(".tinytable")
            // Get the table header cells
            val tableHeaderRow = TableRow(activity)
            tableHeaderRow.isClickable = true
            table.select("thead").select("tr").forEach {row ->
                row.getElementsByTag("th").forEach { cell ->
                Log.d("CELL text", cell.text())
                val textView = TextView(activity)
                textView.text = cell.text()
                tableHeaderRow.addView(textView)

                }
            }
            // Get the table body cells
            table.select("tbody").select("tr").forEach {row ->
                val tableRow = TableRow(requireActivity())
                tableRow.isClickable = true

                row.getElementsByTag("td").forEach { cell ->
                    val textView = TextView(activity)
                    textView.text = cell.text()
                    tableRow.addView(textView)
                }
            }
        }

    }

}
