(b) Analysis:

To use it, you need to inherit Sectionedbaseadapter

6 ways to rewrite adapter

• public Object getItem(int section, int position);
• public long getItemId(int section, int position);
• public int getSectionCount();
• public int getCountForSection(int section);
• public View getItemView(int section, int position, View convertView, ViewGroup parent);
• public View getSectionHeaderView(int section, View convertView, ViewGroup parent);

GetItem (int section, int position); Section:header number of positions,position: number of positions for normal item

Getitemid (int section, int position); Gets the ID of item number section of position

Getsectioncount (); Total number of//header

getcountforsection (int section); //Total number of ordinary item

Getitemview (int section, int position, View Convertview, viewgroup parent);

Normal item Load view method similar to adapter in GetView () method

getsectionheaderview (int section, View Convertview, viewgroup parent);

Header Item Loads the view method also similar to adapter in the GetView () method

You can use HashMap to save the list when you use it to display data through sections and position.

The section can also be judged separately to show the different headers
