Android 實現氣泡式listview【附源碼】

iPhone中短信聊天都是那種氣泡式的，當然，Android短信也是。那麼我們如何實現這種效果呢？我下面就簡單的實現了一個demo，其實就是一個listview，然後對adapter中getview的時候，根據自己的設定來獲取不同的layout。

具體看代碼：

1. public class MainActivity extends Activity {
2. private ListView talkView;
3. private ArrayList<DetailEntity> list = null;
4. public void onCreate(Bundle savedInstanceState) {
5. super.onCreate(savedInstanceState);
6. setContentView(R.layout.main);
8. talkView = (ListView)findViewById(R.id.list);
10. list = new ArrayList<DetailEntity>();
11. DetailEntity d1 = new DetailEntity("Me","2012-04-26","Hello!",R.layout.list_say_me_item);
12. list.add(d1);
13. DetailEntity d2 = new DetailEntity("You","2012-04-26","Hi!",R.layout.list_say_he_item);
14. list.add(d2);
15. DetailEntity d3 = new DetailEntity("Me","2012-04-26","Waht is your name?",R.layout.list_say_he_item);
16. list.add(d3);
17. DetailEntity d4 = new DetailEntity("You","2012-04-26","****!",R.layout.list_say_me_item);
18. list.add(d4);
20. talkView.setAdapter(new DetailAdapter(MainActivity.this, list));
21. }
22. }
