PullToRefreshListView添加headView的方法

前段时间工作需要使用PullToRefreshListView进行下拉刷新上拉加载更多，
并且添加头布局，网络找到了方法，仅记录。（注意：PullToRefreshListView无数据时头布局也不会展示）

private PullToRefreshListView myListView;
private ListView lv;

myListView = (PullToRefreshListView) findViewById(R.id.listview_temple);
//注意：headView的参数二父布局填写的PullToRefreshListView 
View headView = LayoutInflater.from(TempleActivity.this).inflate(R.layout.head_temple, myListView, false);

//定义LayoutParams，将它添加至headView
AbsListView.LayoutParams layoutParams = new AbsListView.LayoutParams(AbsListView.LayoutParams.MATCH_PARENT, AbsListView.LayoutParams.WRAP_CONTENT);
headView.setLayoutParams(layoutParams);
//获取PullToRefreshListView 中的ListView

lv = myListView.getRefreshableView();
lv.setDivider(getResources().getDrawable(R.color.white));
//添加头布局
lv.addHeaderView(headView);
//设置Adapter等
