Android学习（30） -- ArrayAdapter&SimpleAdapter

ArrayAdapter

当列表只要一列的时候使用

	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

当列表有多列的时候使用

		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}))
