Android Listview多次调用相同的addHeaderView和addFooterView 问题

getFooterViewsCount

getHeaderViewsCount

private void setView(ListView listView, String s, View view) {

switch (s) {
case "footview":
if (listView.getFooterViewsCount() == 0) {
listView.addFooterView(view);
}
break;
case "headview":
if (listView.getHeaderViewsCount() == 0) {
listView.addHeaderView(view);
}
break;
}

}

View title0 = View.inflate(context, R.layout.plandetails_headtitle, null);
TextView textView = (TextView) title0.findViewById(R.id.listView_details_title);
textView.setText("收到5个橄榄枝");
View footview0 = View.inflate(context, R.layout.footview_view_plan_details, null);

setView(lstMoreRec, "footview", footview0);
setView(lstMoreRec,"headview", title0);
lstMoreRec.setAdapter(adapter_recomment);
