如何从recylerview到新片段从项目导航

Question

有人可以帮助我弄清楚我应该如何从循环系统的项目导航到此重新碎片吗？我想使用github api将这些内容显示在repofragment中。

我想单击“回收器”视图项目中的redoname。使用OnClickListener，我希望打开一个新的片段（repofoffragment），其中包含RecyClerview的单击项目的信息。

我正在进行存储库搜索，并希望在单击存储库时显示信息。下面的代码表示我尝试做的事情。 感谢您的帮助！

这是我的repositoryRecyclerAdapter：

class RepositoryRecyclerAdapter(repos: List<RepositoriesResponse>): RecyclerView.Adapter<SearchPlaceHolder>(){

private var repoList = repos
var navc: NavController?= null


override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): SearchPlaceHolder {
    val inflatedView = LayoutInflater.from(parent.getContext()).inflate(R.layout.pravokutnik, parent, false);
    return SearchPlaceHolder(inflatedView)
}

override fun onBindViewHolder(holder: SearchPlaceHolder, position: Int) {
    val repo = repoList[position]
    holder.bindRepo(repo)

   
    holder.itemView.setOnClickListener(object: View.OnClickListener{
        override fun onClick(v: View){
            navc?.navigate(R.id.action_searchFragment_to_repoFragment)
            }
        })
    

}

override fun getItemCount() = repoList.size

}

这是我的搜索范围：

class SearchFragment : BaseFragment<SearchViewModel, FragmentSearchBinding, SearchRepository>() {

private lateinit var mContext: Context
private var reposList = ArrayList<RepositoriesResponse>().toList()
private lateinit var adapterRepo: RepositoryRecyclerAdapter
private lateinit var linearLayoutManagerDistance: LinearLayoutManager




val args: SearchFragmentArgs by navArgs()

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    super.onViewCreated(view, savedInstanceState)
    mContext = this.requireContext()

    linearLayoutManagerDistance = LinearLayoutManager(mContext)
    linearLayoutManagerDistance.orientation = LinearLayoutManager.VERTICAL
    binding.repositoriesList.layoutManager = linearLayoutManagerDistance


    

    val query = args.query

    val apiInterface = RepositoryApi.create().getRepositoriesByQuery(query)

    



    apiInterface.enqueue( object : Callback<QueryResponse> {
        override fun onResponse(call: Call<QueryResponse>?, response: Response<QueryResponse>?) {
            if(response?.body() != null){
                reposList = response.body()!!.items
                adapterRepo = RepositoryRecyclerAdapter(reposList)
                binding.repositoriesList.adapter = adapterRepo

            }

        }

        override fun onFailure(call: Call<QueryResponse>?, t: Throwable?) {
            Toast.makeText(mContext, t.toString(), Toast.LENGTH_LONG).show()
        }


    })




}




override fun getViewModel() = SearchViewModel::class.java

override fun getFragmentBinding(
    inflater: LayoutInflater,
    container: ViewGroup?
) = FragmentSearchBinding.inflate(inflater, container, false)

override fun getFragmentRepository()=
    SearchRepository()

}

homefragment：

class HomeFragment : BaseFragment<HomeViewModel, FragmentHomeBinding, SearchRepository>() {


override fun onCreateView(
    inflater: LayoutInflater, container: ViewGroup?,
    savedInstanceState: Bundle?
): View? {
    return inflater.inflate(R.layout.fragment_home, container, false)
}

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

    var mySearchView = view.findViewById<SearchView>(R.id.search_view)
    var navc = Navigation.findNavController(view)

    mySearchView.setIconifiedByDefault(true);
    mySearchView.setOnQueryTextListener(object : SearchView.OnQueryTextListener {
        override fun onQueryTextSubmit(query: String): Boolean {
            val action = HomeFragmentDirections.actionHomeFragmentToSearchFragment2(query)
            navc?.navigate(action)
            return false
        }

        override fun onQueryTextChange(newText: String?): Boolean {
            return false
        }
    })

}

override fun getViewModel() = HomeViewModel::class.java

override fun getFragmentBinding(
    inflater: LayoutInflater,
    container: ViewGroup?
) = FragmentHomeBinding.inflate(inflater, container, false)

override fun getFragmentRepository()=
    SearchRepository()

}

repoffragment：

class RepoFragment : BaseFragment<RepoViewModel, FragmentRepoBinding, SearchRepository>(){

override fun onCreateView(
    inflater: LayoutInflater, container: ViewGroup?,
    savedInstanceState: Bundle?
): View? {
    return inflater.inflate(R.layout.fragment_repo, container, false)
}

override fun getViewModel() = RepoViewModel::class.java


override fun getFragmentBinding(
    inflater: LayoutInflater,
                                container: ViewGroup?
) = FragmentRepoBinding.inflate(inflater, container, false)


override fun getFragmentRepository() = SearchRepository()

}

另外，我在尝试运行此代码时会遇到错误； AndroidStudio说，我在夸大折线的布局时犯了一个错误。
