public class MainActivity extends Activity { List<String> list; List<String> list1; @Override public void onCreate(Bundle savedInstanceState) { super .onCreate(savedInstanceState); setContentView(R.layout.main); ListView listView = (ListView) this .findViewById(R.id.listView); //获取到集合数据 //名字列表,之后可以动态加入数据即可,这里只是数据例子 list = new ArrayList<>(); list.add( "小明" ); list.add( "李华" ); list.add( "张三" ); list1 = new ArrayList<>(); list1.add( "男" ); list1.add( "男" ); list1.add( "女" ); List<HashMap<String, Object>> data = new ArrayList<HashMap<String,Object>>(); for ( int i = 0 ; i < list .size(); i++){ HashMap<String, Object> item = new HashMap<String, Object>(); item.put( "name" , list.get(i)); item.put( "sex" , list1.get(i)); data.add(item); } //创建SimpleAdapter适配器将数据绑定到item显示控件上 SimpleAdapter adapter = new SimpleAdapter(MainActivity. this , data, R.layout.item, new String[]{ "name" , "sex" }, new int []{R.id.name, R.id.sex}); //实现列表的显示 listView.setAdapter(adapter); } } |
