显示"You must call removeView() on the child's parent first"错误的回收器适配器

Question

我做了一个recyclerview适配器，在其中我在recyclerview中显示了很多东西。而且我还在使用ViewPager的视图中显示了一些图像。它的工作正常，但是当我添加viewPagerarrowIndicator库以供ViewPager指示器显示上述错误，当时我从底部滚动回到底部。我尝试过使用StackoverFlow的解决方案，但是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>

尝试使用另一个库，即使您不想将其用于测试。

也许您可以尝试 - https：//github.com/ongakuer/circleindicator
