进度条不隐藏是当数据在片段中的recyclerview中加载时

Question

我创建了一个接口并扩展到类

class MoviesandTv(override var mprogressdialog: Dialog) : Fragment() , CDialogs {
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
    val view: View = inflater.inflate(R.layout.moviesandtv, container, false)
    setHasOptionsMenu(true)
    mlinearLayoutManagerrr = LinearLayoutManager(activity)
    mlinearLayoutManagerrr!!.reverseLayout = true
    mlinearLayoutManagerrr!!.stackFromEnd = true
    rc_listing_movies_tv = view.rc_list_movies_tv
    showCustomProgressDialog()
    showdata_movies()

    return view
}

并在加载数据时在 onbinderview 上隐藏我的对话框

fun showdata_movies(){

    optionsss = FirebaseRecyclerOptions.Builder<Data>().setQuery(db_movies, Data::class.java).build()

    mfirebaseRecyclerAdapterrr = object : FirebaseRecyclerAdapter<Data, ViewHolder_Movies_TV>(optionsss!!) {
        override fun onBindViewHolder(viewHoldermovies: ViewHolder_Movies_TV, i: Int, model: Data) {
            hideCustomProgressDialog()
            viewHoldermovies.setDetails(activity, model.movie_title, model.review, model.date)

但只是显示对话框，并没有在onbenderview中隐藏它

我实现的方法是

override  fun showCustomProgressDialog() {
    mprogressdialog = context.let { Dialog(it!!) }
    mprogressdialog.setContentView(R.layout.custom_dialog)
    mprogressdialog.show() }


override fun hideCustomProgressDialog() {
    mprogressdialog!!.dismiss()
}

因为您使用的是FirebaseRecyclerAdapter，所以您可以选择覆盖以下方法并隐藏ProgressBar，如以下代码行所示：

@Override
public void onDataChanged() {
    if (progressBar != null) {
        progressBar.setVisibility(View.GONE);
    }
}
