Question

我已经制作了一个recyclerview适配器，我在recyclerview中展示了很多东西。我也在viewpager的视图中显示一些图像。它的工作正常，但是当我为viewpager指示器添加viewPagerArrowIndicator库时，它在我从上往上滚动回来时显示上面的错误。 我尝试过使用stackoverflow的解决方案，但没有类似的错误或解决方案

我的适配器代码：

        //image slider
        if(newsFeedClassArrayList.get(position).getImageList()!=null){

            holder.viewPager.setVisibility(View.VISIBLE);
            viewPagerAdapter=new ViewPagerAdapter(context,newsFeedClassArrayList.get(position).getImageList());
            holder.viewPager.setAdapter(viewPagerAdapter);


**//error showing below on line**
            holder.viewPagerArrowIndicator.bind(holder.viewPager);
            holder.viewPagerArrowIndicator.setArrowIndicatorRes(R.drawable.arrow_left_black_24dp,R.drawable.arrow_right_black_24dp);

            viewPagerAdapter.notifyDataSetChanged();

        }else {
            holder.viewPager.setVisibility(View.GONE);
        }

        holder.timeStampTvId.setText(newsFeedClass.getTimeStamp());

xml代码：

<com.sembozdemir.viewpagerarrowindicator.library.ViewPagerArrowIndicator
        android:id="@+id/viewPagerArrowIndicator"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">

    <android.support.v4.view.ViewPager
        android:layout_width="wrap_content"
        android:layout_height="180dp"
        android:id="@+id/viewPagerId_imageView"
        android:minHeight="0dp"
        >
    </android.support.v4.view.ViewPager>

    </com.sembozdemir.viewpagerarrowindicator.library.ViewPagerArrowIndicator>

尝试使用其他库，即使您不想使用它只是用它来进行测试。
