如何为布尔变量创建一个侦听器？

Question

我希望视频在屏幕向上滚动时停止播放。 我为此使用addOnScrollListener。

  public boolean scrolldurum;

      rv.addOnScrollListener(new RecyclerView.OnScrollListener() {
                @Override
                public void onScrollStateChanged(@NonNull RecyclerView recyclerView, int  newState) {
                   // mScrollState = scrollState;
                    if(newState == RecyclerView.SCROLL_STATE_IDLE  ) {
                        Toast.makeText(getActivity(),"scrol stop",Toast.LENGTH_SHORT).show();
                        scrolldurum = false;
                        Log.e("scrolldurumburcu", String.valueOf(scrolldurum));


                    }
                    if(newState == RecyclerView.SCROLL_STATE_DRAGGING  ) {
                        Toast.makeText(getActivity(),"scrol START",Toast.LENGTH_SHORT).show();
                        scrolldurum = true;
                        Log.e("scrolldurumburcu", String.valueOf(scrolldurum));


                }
                    super.onScrollStateChanged(recyclerView, newState);
            }
        });

我的布尔变量在屏幕滚动时为true，在停止时为false。 但是视频停止代码仅在onBindViewHolder中有效。

    @Override
        public void onBindViewHolder(final KelimelerAdapterx.CardTasarimTutucu holder, int position) {
            final Kelimeler kelime = kelimelerListe.get(position);

            holder.textViewIngilizce.setText(kelime.getAkis());
            holder.textViewTurkce.setText(kelime.getLikebtn());


if (scrolldurum = true){
    Log.e("xaxaxaxax", String.valueOf(scrolldurum));
    holder.videoView.pause();


}
            if (scrolldurum = false){
                Log.e("xaxaxaxax", String.valueOf(scrolldurum));

            }
            holder.videoView.setErrorTracker(new SimpleVideoView.VideoPlaybackErrorTracker() {
                @Override
                public void onPlaybackError(Exception e) {
                    e.printStackTrace();
                    //   Snackbar.make(holder.videoView, "Uh oh, error playing!", Snackbar.LENGTH_INDEFINITE).show();
                    holder.videoView.start("https://goldgym.pro/imga/"+holder.textViewTurkce.getText().toString());
                    holder. videoView.setOnClickListener(new View.OnClickListener() {
                        @Override
                        public void onClick(View view) {
                            if ( holder.videoView.isPlaying()) {
                                holder.videoView.pause();

                            }
                            else{
                                holder.videoView.play();
                            }


                        }
                    });
                }
            });

          holder.videoView.start("https://goldgym.pro/imga/"+holder.textViewTurkce.getText().toString());


            holder. videoView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {



                    if ( holder.videoView.isPlaying()) {
                        Log.e("scrolldurumburcussss", String.valueOf(scrolldurum));

                        holder.videoView.pause();
                    } else {
                        holder.videoView.play();

                    }

                }

            });

        }

我的布尔变量需要一个侦听器。 我怎样才能做到这一点。 如果您想查看我的完整代码。 https://gist.github.com/prensmiskin/161741f6e497a9d624258bedbddfd9d8
