下面是activity:

public class MainActivity extends Activity {    private ListView mListView = null;    private List
     
       mList = null;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        mListView = (ListView) this.findViewById(R.id.main_listView);        mList = new ArrayList
      
       ();        initData();        Collections.sort(mList, new Comparator
       
        () {            /**             *              * @param lhs             * @param rhs             * @return an integer < 0 if lhs is less than rhs, 0 if they are             *         equal, and > 0 if lhs is greater than rhs,比较数据大小时,这里比的是时间             */            @Override            public int compare(TestDate lhs, TestDate rhs) {                Date date1 = DateUtil.stringToDate(lhs.getDate());                Date date2 = DateUtil.stringToDate(rhs.getDate());                // 对日期字段进行升序，如果欲降序可采用after方法                if (date1.before(date2)) {                    return 1;                }                return -1;            }        });        mListView.setAdapter(new MyAdapter(this, mList));    }    private void initData() {        mList.add(new TestDate("2012-12-12 12:30", "zhangsan"));        mList.add(new TestDate("2012-12-12 10:20", "lisi"));        mList.add(new TestDate("2012-12-11 10:21", "lisi"));        mList.add(new TestDate("2012-12-11 10:20", "lisi"));        mList.add(new TestDate("2012-12-13 01:03", "wangwu"));        mList.add(new TestDate("2012-12-10 02:04", "zhaoliu"));        mList.add(new TestDate("2012-12-15 23:00", "tianqi"));        mList.add(new TestDate("2012-11-12 22:30", "wangwu"));        mList.add(new TestDate("2012-12-17 08:24", "shimei"));        mList.add(new TestDate("2012-11-10 11:10", "shisanmei"));        mList.add(new TestDate("2012-12-18 16:50", "wangan"));        mList.add(new TestDate("2012-12-19 18:00", "wangjiu"));        mList.add(new TestDate("2012-12-20 19:30", "wusi"));        mList.add(new TestDate("2012-12-20 19:30", "wusi"));    }}
       
      
     

下面是工具类：

public class DateUtil {    public static Date stringToDate(String dateString) {        ParsePosition position = new ParsePosition(0);        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm");        Date dateValue = simpleDateFormat.parse(dateString, position);        return dateValue;    }}

下面是ListView用的Adapter:

public class MyAdapter extends BaseAdapter {    private Context mContext;    private List
     
       mList;    public MyAdapter(Context context, List
      
        list) {        this.mContext = context;        this.mList = list;    }    @Override    public int getCount() {        return mList != null ? mList.size() : 0;    }    @Override    public Object getItem(int position) {        return mList.get(position);    }    @Override    public long getItemId(int position) {        return position;    }    @Override    public View getView(int position, View convertView, ViewGroup parent) {        ViewHolder holder = null;        if (convertView == null) {            convertView = (LinearLayout) LayoutInflater.from(mContext).inflate(                    R.layout.main_item, null);            holder = new ViewHolder();            holder.textView1 = (TextView) convertView                    .findViewById(R.id.item_textView1);            holder.textVeiw2 = (TextView) convertView                    .findViewById(R.id.item_textView2);            convertView.setTag(holder);        } else {            holder = (ViewHolder) convertView.getTag();        }        holder.textView1.setText(mList.get(position).getDate());        holder.textVeiw2.setText(mList.get(position).getName());        return convertView;    }    private class ViewHolder {        private TextView textView1;        private TextView textVeiw2;    }}
      
     

下面是xml文件：

下面是一个JavaBean的类：

public class TestDate {        private String date;    private String name;    public String getDate() {        return date;    }    public String getName() {        return name;    }    public TestDate(String date, String name) {        this.date = date;        this.name = name;    }}
