本文实例为大家分享了android快递跟踪进度条展示的具体代码，供大家参考，具体内容如下

activity.class

import java.util.ArrayList; import java.util.HashMap; import java.util.List; import java.util.Map;  import android.app.Activity; import android.os.Bundle; import android.widget.ListView;  public class MainActivity extends Activity {   private ListView listView;  List data;  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> getData() {  List> list = new ArrayList>();   Map map = new HashMap();  map.put("time", "2015-05-20 10:15");  map.put("title", "深圳龙华收件");  list.add(map);   map = new HashMap();  map.put("time", "2015-05-21 9:25");  map.put("title", "离开深圳，发往上海");  list.add(map);   map = new HashMap();  map.put("time", "2015-05-22 12:55");  map.put("title", "上海浦江集散中心");  list.add(map);   map = new HashMap();  map.put("time", "2015-05-25 9:30");  map.put("title", "已收取快件");  list.add(map);  return list;  }  }
