13. import android.widget.SimpleAdapter; 
14.  
15. public class GridDemoActivity extends ListActivity { 
16.     /** Called when the activity is first created. */ 
17.     @Override 
18.     public void onCreate(Bundle savedInstanceState) { 
19.         super.onCreate(savedInstanceState); 
20.         setContentView(R.layout.main); 
21.  
22.         LayoutInflater layoutInflater = (LayoutInflater) this 
23.                 .getSystemService("layout_inflater"); 
24.         View headerView=layoutInflater.inflate(R.layout.list_header, null); 
25.         setGridView(headerView); 
26.         ListView listView=(ListView) this.findViewById(android.R.id.list); 
27.         listView.addHeaderView(headerView); 
28.         listView.setAdapter(new ArrayAdapter<String>(this, android.R.layout.易做图_list_item_1,new String[]{"","","","","",""})); 
29.     } 
30.  
31.     private void setGridView(View view) { 
32.         GridView gridView = (GridView) view.findViewById(R.id.grid); 
33.         gridView.setNumColumns(10); 
34.  
35.         ArrayList<HashMap<String, Object>> items = new ArrayList<HashMap<String, Object>>(); 
36.  
37.         for (int i = 0; i < 10; i++) { 
38.             HashMap<String, Object> map = new HashMap<String, Object>(); 
39.             map.put("ItemImage", R.drawable.k); 
40.             map.put("ItemText", "" + "(" + i + ")"); 
41.             items.add(map); 
42.         } 
43.  
44.         SimpleAdapter adapter = new SimpleAdapter(this, items, R.layout.item, 
45.                 new String[] { "ItemImage", "ItemText" }, new int[] { 
46.                         R.id.ItemImage, R.id.ItemText }); 
47.         gridView.setAdapter(adapter); 
48.     }
