Android开发,加载更多数据后点击item后下标越界怎么回事?

@Override
public void onItemChildClick(BaseQuickAdapter adapter, View view, int position) {
if (view.getId() == R.id.play_icon) {//播放图标
HomeListBean homeListBean = mDatas.get(position);
List<HomeListBean.DataBean> data = homeListBean.getData();
Toast.makeText(mContext, "119= "+data.size(), Toast.LENGTH_SHORT).show();
// if(data.size()!=0&&data!=null){}
HomeListBean.DataBean dataBean = data.get(position);//这里越界
String titleName = dataBean.getName();
String subName = dataBean.getSubname();
String coverImg = dataBean.getImg();
int vid = dataBean.getVid();

假如你有10条数据，你的列表末尾有加载更多，就是第十一项，此时你点击“加载更多”就是点击第十一条，此时position 为10，然而你得数据data 只有10条，就是0-9，所以data.get(10)就会出错。
