 private TimelineAdapter timelineAdapter; 
 
 @Override 
 protected void onCreate(Bundle savedInstanceState) { 
 super.onCreate(savedInstanceState); 
 setContentView(R.layout.activity_main); 
 
 listView = (ListView) this.findViewById(R.id.listview); 
 listView.setDividerHeight(0); 
 timelineAdapter = new TimelineAdapter(this, getData()); 
 listView.setAdapter(timelineAdapter); 
 
 } 
 
 private List<Map<String, Object>> getData() { 
 List<Map<String, Object>> list = new ArrayList<Map<String, Object>>(); 
 
 Map<String, Object> map = new HashMap<String, Object>(); 
 map.put("time", "2015-05-20 10:15"); 
 map.put("title", "深圳龍華收件"); 
 list.add(map); 
 
 map = new HashMap<String, Object>(); 
 map.put("time", "2015-05-21 9:25"); 
 map.put("title", "離開深圳，發(fā)往上海"); 
 list.add(map); 
 
 map = new HashMap<String, Object>(); 
 map.put("time", "2015-05-22 12:55"); 
 map.put("title", "上海浦江集散中心");
