下面是activity:
-
public class MainActivity extends Activity {
-
-
private ListView mListView = null;
-
private List<TestDate> 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<TestDate>();
-
initData();
-
Collections.sort(mList, new Comparator<TestDate>() {
-
-
-
-
-
-
-
-
@Override
-
public int compare(TestDate lhs, TestDate rhs) {
-
Date date1 = DateUtil.stringToDate(lhs.getDate());
-
Date date2 = DateUtil.stringToDate(rhs.getDate());
-
-
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<TestDate> mList;
-
-
public MyAdapter(Context context, List<TestDate> 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：
-
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
-
xmlns:tools="http://schemas.android.com/tools"
-
android:layout_width="match_parent"
-
android:layout_height="match_parent" >
-
-
<ListView
-
android:id="@+id/main_listView"
-
android:layout_width="match_parent"
-
android:layout_height="match_parent"
-
android:layout_centerHorizontal="true"
-
android:layout_centerVertical="true"
-
tools:context=".MainActivity" />
-
-
</RelativeLayout>
-
<?xml version="1.0" encoding="utf-8"?>
-
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
-
android:layout_width="match_parent"
-
android:layout_height="match_parent"
-
android:orientation="horizontal" >
-
-
<TextView
-
android:id="@+id/item_textView1"
-
android:layout_width="wrap_content"
-
android:layout_height="wrap_content"
-
android:layout_gravity="center_vertical"
-
android:layout_margin="10dp" />
-
-
<TextView
-
android:id="@+id/item_textView2"
-
android:layout_width="wrap_content"
-
android:layout_height="wrap_content"
-
android:layout_gravity="center_vertical" />
-
-
</LinearLayout>
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;
-
}
-
-
}
