SimpleAdapter方式

ArrayList> list=new ArrayList>();

Map map1=new HashMap();

map1.put("icon", R.drawable.ic1);

map1.put("name", "功能一");

list.add(map1);

Map map2=new HashMap();

map2.put("icon", R.drawable.ic2);

map2.put("name", "功能二");

list.add(map2);

Map map3=new HashMap();

map3.put("icon", R.drawable.ic3);

map3.put("name", "功能三");

list.add(map3);

Map map4=new HashMap();

map4.put("icon", R.drawable.ic1);

map4.put("name", "功能四");

list.add(map4);

Map map5=new HashMap();

map4.put("icon", R.drawable.ic5);

map4.put("name", "功能五");

list.add(map5);

listView1.setAdapter(new SimpleAdapter(this, list, R.layout.list_item, new String[]{"icon","name"},new int[]{R.id.tubiao,R.id.gongneng} ));
