下方放置ViewPager+Fragment作为滚动布局

[lalozhang]

你好，如果下方的滚动布局换成ViewPager+Fragment这种，Fragment里放RecyclerView，RecyclerView的Adapter的ItemView里有图片的话，上滑时，会出现重影，闪一下，如果去掉自定义的bahavior，就没问题，请作者帮忙看下 谢谢~

这个是Activity里的布局文件

这个是ViewPager里的Fragment的布局文件

<android.support.v7.widget.RecyclerView
    android:id="@+id/recyclerView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

这个是Fragment里Adapter的item_layout

                android:layout_weight="1"
                />

            <TextView
                android:id="@+id/tvLikeCount"

        </LinearLayout>
    </LinearLayout>
</LinearLayout>

</android.support.v7.widget.CardView>

这个是Adapter的部分代码

@OverRide
public HomePageViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
HomePageViewHolder viewHolder = new HomePageViewHolder(LayoutInflater.from(fragment.getActivity()).
inflate(R.layout.item_home_page, parent, false));
LinearLayout.LayoutParams lp = (LinearLayout.LayoutParams) viewHolder.ivPhoto.getLayoutParams();
lp.height = CommonUtils.getScreenWidth()/2;
viewHolder.ivPhoto.setLayoutParams(lp);
return viewHolder;
}

@Override
public void onBindViewHolder(HomePageViewHolder holder, int position) {
    final GoodsInfo item = data.get(position);
    holder.itemView.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {

        }
    });
    if(item!=null){

        if(!ArrayUtil.isEmpty(item.getGoodsImgs())){
            String url = item.getGoodsImgs().get(0);
            String tag = (String) holder.ivPhoto.getTag();
            if(TextUtils.isEmpty(tag)||!tag.equals(url)){
                holder.ivPhoto.setTag(url);
                ImageLoaderRoundManager.getImageLoader().displayImage(url,
                        holder.ivPhoto, ImageLoaderRoundManager.getImageOptions());
            }

        }else{
            holder.ivPhoto.setImageResource(R.drawable.default_pic);
        }

        holder.dlvGoodsName.setData(item.getGoodsBrand(),item.getGoodsName());
        holder.cpvPrice.setData(item);
        holder.tvLikeCount.setText(item.getWantCount()+"");
    }

}

activity要透明状态栏，然后那个imageview设置android:fitsSystemWindows="true"
这样修改后应该就好了
