listview 适配器多类型

来源：互联网发布：h5切水果游戏源码编辑：程序博客网时间：2024/05/22 02:40

主要是BaseAdapter适配器中的两个方法：

返回类型个数

@Override    public int getViewTypeCount() {        return 2;    }

定义每个位置的类型id:

 @Override    public int getItemViewType(int position){        if(position == list.size()){            return 1;        }else{            return 0;        }    }

在getView方法中根据getItemViewType的id去定义
