1、因为给LISTVIEW增加了两个头布局，所以在点击事件ITEM索引会增加2，比如原来第一条数据的索引应该为0，增加两个头布局后，它的索引变为 2，为了使LISTVIEW的ITEM在点击时索引不变，实现以下方法
2、实现接口android.widget.AdapterView.OnItemClickListener
3、重写setOnItemClickListener onItemClick方法
private OnItemClickListener mItemClickListener;
// 重写item点击方法
@Override
public void setOnItemClickListener(
android.widget.AdapterView.OnItemClickListener listener) {
mItemClickListener = listener;
super.setOnItemClickListener(this);// 将点击事件设置给当前的RefreshListView
}
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
if (mItemClickListener != null) {
mItemClickListener.onItemClick(parent, view, position
- getHeaderViewsCount(), id);
}
}
