有头尾布局的条目点击


lv.setOnItemCLick


onItemClick(AdapterView<?> parent, View view, int position, long id)


现在有头尾布局


点击头部 position=0
点击尾部 position=list.size()+1;


size=0,headPosition=0,footPosition=1;有效0
size=1,headPosition=0,footPosition=2;有效1
size=2,headPosition=0,footPosition=3;有效1,2
size=3,headPosition=0,footPosition=4;有效1,2,3
size=4,headPosition=0,footPosition=5;有效1,2,3,4


所以,
if(list==null || position <= 0 || position > list.size()){
return;
}


list.get(position-1)
