Android学习（30） -- ArrayAdapter&SimpleAdapter

ArrayAdapter

String[] objects = new String[]{
"小小1",
"小小2",
"小小3"
};

ListView lv = (ListView) findViewById(R.id.lv);
lv.setAdapter(new ArrayAdapter<String>(this, R.layout.item_listview, R.id.tv_name, objects));

SimpleAdapter

ListView lv = (ListView) findViewById(R.id.lv);

//集合中每个元素都包含ListView条目需要的所有数据,该案例中每个条目需要一个字符串和一个整型,所以使用一个map来封装这两种数据
List<Map<String, Object>> data = new ArrayList<Map<String,Object>>();

Map<String, Object> map1 = new HashMap<String, Object>();
map1.put("photo", R.drawable.photo1);
map1.put("name", "小小1");
data.add(map1);

Map<String, Object> map2 = new HashMap<String, Object>();
map2.put("photo", R.drawable.photo2);
map2.put("name", "小小2");
data.add(map2);

Map<String, Object> map3 = new HashMap<String, Object>();
map3.put("photo", R.drawable.photo3);
map3.put("name", "小小3");
data.add(map3);

lv.setAdapter(new SimpleAdapter(this, data, R.layout.item_listview,
new String[]{"photo", "name"}, new int[]{R.id.iv_photo, R.id.tv_name}))
