我正在构建一个应用程序，它从Main Activity上的API返回Github用户列表，并在Detail User Activity上返回所选用户的详细信息。当我运行应用程序时，Main Activity使用RecyclerView显示列表，但当我按下其中一个用户时，我的应用程序移动到该Activity，但不会显示任何内容。同样在我的Logcat中，有一个错误说No adapters attached，skipping layout.即使我没有任何RecyclerView在我的详细活动.
下面是我的MainActivity：

package com.example.githubuser

import android.app.SearchManager
import android.content.Context
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.util.Log
import android.view.Menu

class MainActivity : AppCompatActivity() {

    private lateinit var binding: ActivityMainBinding
    private lateinit var mainViewModel: MainViewModel

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        binding = ActivityMainBinding.inflate(layoutInflater)
        setContentView(binding.root)

        val mainViewModel = ViewModelProvider(this, ViewModelProvider.NewInstanceFactory()).get(MainViewModel::class.java)
        mainViewModel.listUsers.observe(this) { listUsers ->
            val adapter = UsersAdapter(listUsers)
            binding.rvUsers.adapter = adapter
            val layoutManager = LinearLayoutManager(this)
            binding.rvUsers.layoutManager = layoutManager
        }

        mainViewModel.isLoading.observe(this) {
            showLoading(it)
        }

    }

    private fun showUsers(listUsers: List<ItemsItem>) {
        val adapter = UsersAdapter(listUsers)
        binding.rvUsers.adapter = adapter
        val layoutManager = LinearLayoutManager(this)
        binding.rvUsers.layoutManager = layoutManager
    }

    override fun onCreateOptionsMenu(menu: Menu): Boolean {
        val inflater = menuInflater
        inflater.inflate(R.menu.option_menu, menu)

        val searchManager = getSystemService(Context.SEARCH_SERVICE) as SearchManager
        val searchView = menu.findItem(R.id.search).actionView as SearchView

        searchView.setSearchableInfo(searchManager.getSearchableInfo(componentName))
        searchView.queryHint = resources.getString(R.string.search_hint)

        searchView.setOnQueryTextListener(object : SearchView.OnQueryTextListener {
            override fun onQueryTextSubmit(que: String): Boolean {
                showLoading(true)
                getUserSearchData(query = que)
                searchView.clearFocus()
                return true
            }
            override fun onQueryTextChange(newText: String): Boolean {
                return false
            }
        })
        return true
    }

    private fun getUserSearchData (query : String){
        ApiConfig.getApiService().getUsers(query = query).enqueue(object : Callback<GithubResponse>{
            override fun onResponse(
                call: Call<GithubResponse>,
                response: Response<GithubResponse>
            ) {
                showLoading(false)
                if (response.isSuccessful){
                    val filteredUsers = response.body()?.items?.filter { it.login.contains(query, true) }
                    showUsers(filteredUsers ?: emptyList())
                }else{
                    Log.e("MainViewModel", "onFailure: ${response.message()}")
                }
            }
            override fun onFailure(call: Call<GithubResponse>, t: Throwable) {
                showLoading(false)
                Log.d("TAG", "${t.message}")
            }
        })
    }

    private fun showLoading(isLoading: Boolean) {
        binding.progressBar.visibility = if (isLoading) View.VISIBLE else View.GONE
    }
}

下面是我的UsersAdapter：

package com.example.githubuser

import android.content.Intent

import android.widget.ImageView
import android.widget.TextView

class UsersAdapter(private var listUsers: List<ItemsItem>): RecyclerView.Adapter<UsersAdapter.MyViewHolder>() {

    companion object {
        const val EXTRA_USER = "user"
    }

    override fun onCreateViewHolder(viewGroup: ViewGroup, viewType: Int) =
        MyViewHolder(LayoutInflater.from(viewGroup.context).inflate(R.layout.item_users, viewGroup, false))

    override fun onBindViewHolder(myViewHolder: MyViewHolder, position: Int) {
        val user = listUsers[position]
        myViewHolder.tvUser.text = user.login
        Glide.with(myViewHolder.ivUser)
            .load(listUsers[position].avatarUrl)
            .into(myViewHolder.ivUser)

        myViewHolder.itemView.setOnClickListener {
            val intent = Intent(myViewHolder.itemView.context, DetailUserActivity::class.java)
            val userResponse = UserResponse(
                gistsUrl = "",
                reposUrl = "",
                followingUrl = "",
                createdAt = "",
                login = user.login,
                type = "",
                blog = "",
                subscriptionsUrl = "",
                updatedAt = "",
                siteAdmin = false,
                company = "",
                id = user.id,
                publicRepos = 0,

                url = "",
                receivedEventsUrl = "",
                followers = 0,
                avatarUrl = user.avatarUrl,
                eventsUrl = "",
                htmlUrl = "",
                following = 0,
                name = "",
                location = "",
                nodeId = ""
            )
            intent.putExtra(UsersAdapter.EXTRA_USER, userResponse)
            intent.putExtra("photo", user.avatarUrl)
            myViewHolder.itemView.context.startActivity(intent)
            }
        }

    override fun getItemCount() = listUsers.size

    class MyViewHolder(view: View) : RecyclerView.ViewHolder(view) {
        val tvUser: TextView = view.findViewById(R.id.tv_users)
        val ivUser: ImageView = view.findViewById(R.id.iv_users)
    }
}

下面是我的DetailUserActivity：

package com.example.githubuser

import DetailViewModel

import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.view.View
import android.widget.ImageView

import org.w3c.dom.Text

class DetailUserActivity : AppCompatActivity() {

    private lateinit var binding: ActivityMainBinding

    private lateinit var adapter: UsersAdapter

    companion object {
        const val EXTRA_NAME = "extra_name"
        const val EXTRA_USERNAME = "extra_username"
        const val EXTRA_FOLLOWERS = "extra_followers"
        const val EXTRA_FOLLOWING = "extra_following"
    }

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        binding = ActivityMainBinding.inflate(layoutInflater)
        setContentView(binding.root)
        val viewModel = ViewModelProvider(this)[DetailViewModel::class.java]
//        adapter = UsersAdapter(ItemsItem)

        val tv_name = findViewById<TextView>(R.id.name)
        val avatar_user = findViewById<ImageView>(R.id.userPhoto)
        val tv_username = findViewById<TextView>(R.id.username)
        val tv_followers = findViewById<TextView>(R.id.followers)
        val tv_following = findViewById<TextView>(R.id.following)

        val user = intent.getParcelableExtra<UserResponse>("user_key")

        val login = intent.getStringExtra(EXTRA_USERNAME)
        if (login != null) {
            viewModel.getDetailUser(login)
        }

        viewModel.userDetail.observe(this, Observer {
            if (user != null){
                showLoading(false)
                Glide.with(this)
                    .load(user.avatarUrl)
                    .into(avatar_user)
                tv_name.text = user.name
                tv_username.text = user.login

//                tv_location.text = user.location
                tv_followers.text = user.followers.toString()
                tv_following.text = user.following.toString()
            }
        })
    }
    private fun showLoading(isLoading: Boolean) {
        binding.progressBar.visibility = if (isLoading) View.VISIBLE else View.GONE
    }
}

我试着在其他问题上寻找这个特定的错误，但我似乎找不到答案。
