当webView作为recyclerView的一个布局，导致点击webView返回顶部的问题。

public class ArticleAdapter extends RecyclerView.Adapter {

public static final int HEADER_VIEW = 111;

private String mWebUrl;
private List<String> mList = new ArrayList<>();

public String getWebUrl() {
return mWebUrl;
}

public void setWebUrl(String webUrl) {
mWebUrl = webUrl;
}

public List<String> getList() {
return mList;
}

public void setList(List<String> list) {
if (list != null) {
mList.clear();
addList(list);
}
}

public void addList(List<String> list) {
if (list != null) {
mList.addAll(list);
notifyDataSetChanged();
}
}

@Override
public int getItemViewType(int position) {
if (position == 0) {
return HEADER_VIEW;
} else {
return ITEM_VIEW;
}
}

@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
if (viewType == HEADER_VIEW) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_article_header, parent, false);
HeaderViewHolder holder = new HeaderViewHolder(view, parent.getContext());
return holder;
} else {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_article_normal, parent, false);
return new ItemViewHolder(view);
}
}

@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
if (holder instanceof HeaderViewHolder) {
((HeaderViewHolder) holder).bindData(mWebUrl);
} else {
((ItemViewHolder) holder).binData(mList.get(position - 1));
}
}

@Override
public int getItemCount() {
return mList.size() + 1;
}
