我想在两个以上的函数中访问后期初始化变量我该如何使用它？实际上，当请求接受或拒绝时，我想从 recyclerview 中删除该项目
1.这是我的片段类
lateinit var adapterPendingRequest: FriendsPendingRequestAdapter
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
floatingActionButton = view.findViewById(R.id.addFriendFloatingButton)
recyclerPendingRequest = view.pendingRequestsRecyclerId
recyclerPendingRequest.layoutManager = LinearLayoutManager(requireContext())
recyclerViewFriendList = view.friendListRecyclerView
recyclerViewFriendList.layoutManager = LinearLayoutManager(requireContext())
adapterPendingRequest = FriendsPendingRequestAdapter(activity!!)
floatingActionButton.setOnClickListener {
findNavController().navigate(R.id.action_friendListFragmentId_to_searchFriendFragment)
}
actionMoreButton = view.moreMenuOptionId
actionMoreButton.setOnClickListener {
showPopup()
}
//Get FriendRequest Function
getFriendRequest()
//FriendList
addedFriendsList()
Log.e("size", modelPendingRequest.size.toString())
}
2.这个适配器在getFriendRequest函数中工作正常 这是我从recyclerview中的服务器获取列表并接受或拒绝请求但项目没有在按钮单击时删除的函数
private fun getFriendRequest() {
val getHttpRequest = HttpRequest()
Log.e("ResponseText","Inside fun")
getHttpRequest.setOnResponseListener { getRequestResponse ->
Log.e("ResponseText", getRequestResponse.text)
Log.e("get ResponseCode", getRequestResponse.code.toString())
if (getRequestResponse.code == HttpResponse.HTTP_OK) {
Log.e("get in ResponseCode", getRequestResponse.code.toString())
val jsonArray = getRequestResponse.toJSONArray()
modelPendingRequest.clear()
for (i in 0 until jsonArray!!.length()) {
val jsonObject = jsonArray.getJSONObject(i)
val getRequestUserName = jsonObject.getString("username")
val getRequestImage = jsonObject.getString("image")
val getRequestFirstName = jsonObject.getString("first_name")
val getRequestLastName = jsonObject.getString("last_name")
modelPendingRequest.add(SearchUserModel(getRequestUserName,getRequestImage,getRequestFirstName,getRequestLastName))
//adapter to set all data in recyclerview
adapterPendingRequest.setData(modelPendingRequest)
recyclerPendingRequest.adapter = adapterPendingRequest
Log.e("sizes", modelPendingRequest.size.toString())
appGlobals.saveString("requestUser", getRequestUserName)
}
} else if (getRequestResponse.code != HttpResponse.HTTP_OK) {
Toast.makeText(requireContext(), getRequestResponse.text, Toast.LENGTH_SHORT).show()
}
}
getHttpRequest.setOnErrorListener {
Log.e("Get Request Error", it.toString())
}
val token = appGlobals.getValueString("userToken")
Log.e("requestToken", token.toString())
val headers = HttpHeaders("Authorization", "Token $token")
getHttpRequest.get(AppGlobals.GET_FRIEND_REQUEST_API, headers)
Log.e("ResponseText","end of fun")
}}
3. 但不在这里
fun acceptRequest(position: Int) {
val acceptHttRequest = HttpRequest()
val jsonObject = JSONObject()
acceptHttRequest.setOnResponseListener { acceptResponse ->
Log.e("accept ResponseText", acceptResponse.text)
Log.e("accept ResponseCode", acceptResponse.code.toString())
if (acceptResponse.code == HttpResponse.HTTP_OK) {
Log.e("accept ResponseCode", acceptResponse.code.toString())
Log.e("sizes", modelPendingRequest.size.toString())
adapterPendingRequest.removePosition(position)
}
}
acceptHttRequest.setOnErrorListener {
Log.e("Accept Request Error", it.toString())
}
val userName = appGlobals.getValueString("requestUser")
Log.e("Accept Request", "$userName")
try {
jsonObject.put("username", userName)
} catch (e: JSONException) {
Log.e("Accept Request Error", "Error here")
}
val token = appGlobals.getValueString("userToken")
val headers = HttpHeaders("Authorization", "Token $token")
acceptHttRequest.post(AppGlobals.ACCEPT_FRIEND_REQUEST_API, jsonObject, headers)
}
这是适配器类
Class FriendsPendingRequestAdapter(activity: Activity): RecyclerView.Adapter<FriendsPendingRequestAdapter.RequestViewHolder>() {
private var data = ArrayList<SearchUserModel>()
private val requestActivity = activity
private val friendListFragment = FriendListFragment()
var removedPosition : Int ? = null
class RequestViewHolder(requestView: View): RecyclerView.ViewHolder(requestView) {
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): RequestViewHolder {
val view = LayoutInflater.from(parent.context).inflate(R.layout.friend_pending_request_list, parent, false)
return RequestViewHolder(view)
}
override fun onBindViewHolder(holder: RequestViewHolder, position: Int) {
val pendingRequest = data[position]
holder.itemView.friendRequestNameId.text = "${pendingRequest.firstName} ${pendingRequest.lastName}"
Log.e("Request Name", pendingRequest.firstName)
Glide.with(requestActivity)
.load("${AppGlobals.SERVER}${pendingRequest.image}")
.into(holder.itemView.friendRequestImageId)
holder.itemView.confirmRequestButtonId.setOnClickListener {
requestActivity.let { friendListFragment.acceptRequest(position)
// data.removeAt(position)
removedPosition = position
notifyDataSetChanged()}
}
holder.itemView.cancelRequestButtonId.setOnClickListener {
requestActivity.let {friendListFragment.declineRequest(position)
// data.removeAt(position)
removedPosition = position
notifyDataSetChanged()}
}
}
override fun getItemCount(): Int {
return data.size
}
fun setData(tasks: ArrayList<SearchUserModel>) {
this.data = tasks
notifyDataSetChanged()
}
fun removePosition(position: Int): Int? {
data.removeAt(position)
notifyDataSetChanged()
return removedPosition
}
