остановить и отпустить exoplayer из окна просмотра 2

Question

Я использую Exoplayer с ViewPager2.

Домашний фрагмент. java

public class HomeFragment extends Fragment {


    View view;

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

        view= inflater.inflate(R.layout.fragment_home, container, false);

     

        ViewPager2 verticalViewPager = view.findViewById(R.id.vPager);
     
        verticalViewPager.setOrientation(ViewPager2.ORIENTATION_VERTICAL);

        ArrayList<VideoDataModel> dataset = new ArrayList<VideoDataModel>();
        VideoDataModel videoData = new VideoDataModel();
        videoData.setId("1");
        videoData.setUrl("https://cdn.videvo.net/videvo_files/video/free/2019-02/small_watermarked/181004_10_LABORATORIES-SCIENCE_22_preview.webm");
        videoData.setUserid("112800058400468785815");
        videoData.setDescription("Video 1");
        dataset.add(videoData);

        VideoDataModel videoData1 = new VideoDataModel();
        videoData1.setId("2");
        videoData1.setUrl("https://cdn.videvo.net/videvo_files/video/premium/video0122/small_watermarked/100a%20Factory_preview.webm");
        videoData1.setUserid("112800058400468785815");
        videoData1.setDescription("Video 2");
        dataset.add(videoData1);




        ViewPagerAdapter viewPagerAdapter = new ViewPagerAdapter(view.getContext(),dataset);
        verticalViewPager.setAdapter(viewPagerAdapter);


        return  view;

    }





    @Override
    public void onResume() {
        super.onResume();


        BottomNavigationView bottomNavigationView = ((MainActivity) getActivity()).findViewById(R.id.bottom_navigation);
        bottomNavigationView.setBackground( new ColorDrawable(getResources().getColor(android.R.color.black)));
        bottomNavigationView.setItemTextColor(ColorStateList.valueOf(Color.WHITE));
        bottomNavigationView.setItemIconTintList(ColorStateList.valueOf(Color.WHITE));
    }
}

Я хочу отпустить и остановить проигрыватель как Я пролистываю страницу. Только на текущей странице должен быть запущен exoplayer. Запуск всего плеера приводит к проблемам с производительностью. Я попытался использовать метод onViewDetachedFromWindow, чтобы освободить проигрыватель, но если я проведу пальцем назад, мой проигрыватель не будет воспроизводиться ...

Answer 1

ViewPager имеет обратный вызов функции, которые могут быть полезны в вашем случае

• onPageScrolled() - срабатывает при возникновении события прокрутки для текущей страницы
• onPageSelected() - Запускается, когда выбирается новая страница
• onPageScrollStateChanged() - Запускается, когда изменяется состояние прокрутки

Возможно, вы могли бы остановить старую при выборе новой страницы exoplayer и запускаем новый

Answer 2

переопределить следующие методы из вашего ViewpagerAdapter. java класс

и функция просмотра класса, как показано ниже

  @Override
public void onViewDetachedFromWindow(@NonNull VideoPlayerViewHolder holder) {
    super.onViewDetachedFromWindow(holder);
    holder.pausePlayer();
    holder.releasePlayer();
}

@Override
public void onViewAttachedToWindow(@NonNull VideoPlayerViewHolder holder) {
    super.onViewAttachedToWindow(holder);
    holder.startPlayer();
}

Функции ViewHolder

public void startPlayer() {
    player.setPlayWhenReady(true);
    player.getPlaybackState();
}

public void pausePlayer() {
    player.setPlayWhenReady(false);
    player.getPlaybackState();
}

 public void releasePlayer() {
    player.setPlayWhenReady(false);
    player.release();
    player.stop(true);
}

Сообщите мне если есть ошибка ..?

Answer 3

снова инициализируйте игрока во фрагменте окна просмотра при возобновлении, потому что вы освободили поверхность игрока.
