Ich möchte @ erstellViewPager (Inhaber) inRecyclerView Wenn ich es erstelle und einen Pager für die Bildlaufansicht in einer Reihe anlege, dann scrolle ichRecyclerViewund ein Element, das die Komponente wiederverwendet.

Mein Code:

        rcv = (RecyclerView) findViewById(R.id.rcv);
        llom = new LinearLayoutManager(this);
        rcv.setLayoutManager(llom);
        adapter = new MainActivityAdapter(this, hashMap);
        rcv.setAdapter(adapter);

    }
}

MainActivityAdapter

public class MainActivityAdapter extends RecyclerView.Adapter {
    private Context context;
    private static final int TEST = 0;
    private HashMap<Integer, List<String>> hashMap;

    public MainActivityAdapter(Context context, HashMap<Integer, List<String>> hashMap) {
        this.context = context;
        this.hashMap = hashMap;

    }

    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        return new VpListItem(new ViewPagerListItem(context));


    }

    @Override
    public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
        ((VpListItem) holder).fillData(hashMap.get(position), position);

    }

    @Override
    public int getItemCount() {
        return hashMap.size();
    }


    public static class VpListItem extends RecyclerView.ViewHolder {
        private ViewPagerListItem otherArticlesListItem;

        public VpListItem(ViewPagerListItem itemView) {
            super(itemView);
            this.otherArticlesListItem = itemView;
        }

        public void fillData(List<String> list, int position) {
            otherArticlesListItem.fillData(list, position);

        }


    }
}

ViewPagerListItem

public class ViewPagerListItem extends RelativeLayout {
    private Context context;
    private WrapContentViewPager vp;
    private ViewPagerAdapter adapter;
    private List<String> list = new ArrayList<>();


    public ViewPagerListItem(Context context) {
        super(context);
        this.context = context;
        setupView();
    }

    public ViewPagerListItem(Context context, AttributeSet attrs) {
        super(context, attrs);
        this.context = context;
        setupView();
    }

    public ViewPagerListItem(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        this.context = context;
        setupView();
    }

    private void setupView() {
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View view = inflater.inflate(R.layout.vp_list_item, this, true);
        vp = (WrapContentViewPager) view.findViewById(R.id.vp);
        adapter = new ViewPagerAdapter(context, list);
        vp.setAdapter(adapter);


    }

    public void fillData(List<String> list, int id) {
        vp.setId(id);
        this.list.addAll(list);
        adapter.notifyDataSetChanged();


    }
}

ViewPagerAdapter

public class ViewPagerAdapter extends PagerAdapter {
    private Context context;
    private List<String> list;


    public ViewPagerAdapter(Context context, List<String> list) {
        this.context = context;
        this.list = list;


    }

    @Override
    public int getCount() {
        return list.size();
    }

    @Override
    public int getItemPosition(Object object) {
        return POSITION_NONE;
    }

    @Override
    public boolean isViewFromObject(View view, Object object) {
        return view == (View) object;
    }

    @Override
    public void destroyItem(ViewGroup container, int position, Object object) {
        container.removeView((View) object);
    }

    @Override
    public Object instantiateItem(ViewGroup container, final int position) {

        CardListItem cardListItem = new CardListItem(context);
        cardListItem.fillData(list.get(position));
        container.addView(cardListItem);
        return cardListItem;
    }
}


CardListItem

    public class CardListItem extends LinearLayout {
    private Context context;
    private TextView tv;

    public CardListItem(Context context) {
        super(context);
        this.context = context;
        setupView();
    }

    public CardListItem(Context context, AttributeSet attrs) {
        super(context, attrs);
        this.context = context;
        setupView();
    }

    public CardListItem(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        this.context = context;
        setupView();
    }

    private void setupView() {
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View view = inflater.inflate(R.layout.card_list_item, this, true);
        tv = (TextView) view.findViewById(R.id.tv);


    }

    public void fillData(String text) {
        tv.setText(text);


    }
}

Dann scrolle ichRecyclerView irgendwann hinkt es. Und ich scrolleViewPager dann scrolle ichRecyclerView irgendein Element ViewPager das nicht scrollen) ändern nachViewPager dass ich scrolle

Vielen Dank
