邊看世界杯，邊寫博客。記得小時候，去山上玩，翻了兩座山，到了一個叫克勞的地方。那里每到六月份，桃子，杏多的很，有時候你坐在樹上吃一下午都不會有人來，自然了，那里也就人煙稀少。我當時渴急了，在玉米地邊上的牛踩出的蹄窩里喝了一口水，那水真是甘甜哪，忽然覺得腳底下什么在動，抬腳一看，一只螃蟹被我踩到了泥土中。那時候吃野棗，自制槍打野雞，用套套野兔，在河里捉螃蟹，釣魚，在洪水中游泳，上山挖藥，在山上烤紅薯，烤玉米，到了冬天，可以點荒，一盒火柴去見識燎原，這都是經常的事。不知道現在我再去那地方還能不能可以去做這些事情，下周準備回去玩玩，看這些地方是否依然還是那么美麗。
OK，今天我們來看一下如下這個消息管理界面
先上圖，看一下android版本的，先登錄，登陸界面美化之后還像這么回事
我們看一下短消息管理界面
在這里我們還是要首先看一下WebService端
public class MessageMng : System.Web.Services.WebService
{
[WebMethod]
public List<MessageEntity> GetMessageEntity(string sendUser, string receiveUser, string title, string messageType, string startDate, string endDate)
{
try
{
return MessageMngBiz.GetInstance().GetMessageEntity(sendUser, receiveUser, title, messageType, startDate, endDate);
}
catch
{
return new List<MessageEntity>();
}
}
}我們再看一下Biz層
public class MessageMngBiz
{
static MessageMngBiz messageMngBiz = new MessageMngBiz();
private MessageMngBiz()
{ }
public static MessageMngBiz GetInstance()
{
return messageMngBiz;
}
public List<MessageEntity> GetMessageEntity(string sendUser, string receiveUser, string title, string messageType, string startDateStr, string endDateStr)
{
DateTime startDate = DateTime.MinValue;
DateTime endDate = DateTime.MinValue;
if (!string.IsNullOrWhiteSpace(startDateStr))
{
DateTime.TryParse(startDateStr.Trim(), out startDate);
}
if (!string.IsNullOrWhiteSpace(endDateStr))
{
DateTime.TryParse(endDateStr.Trim(), out endDate);
}
return MessageMngDAL.GetInstance().GetMessageEntity(sendUser, receiveUser, title, messageType, startDate == DateTime.MinValue ? null : (DateTime?)startDate, endDate == DateTime.MinValue ? null : (DateTime?)endDate);
}
}再看一下DAL
public class MessageMngDAL
{
static MessageMngDAL messageMngDAL = new MessageMngDAL();
private MessageMngDAL()
{ }
public static MessageMngDAL GetInstance()
{
return messageMngDAL;
}
/// <summary>
///獲取短信息
/// </summary>
/// <param name="sendUser">發送者</param>
/// <param name="receiveUser">接收者</param>
/// <param name="title">標題</param>
/// <param name="messageType">類型(未讀/已讀,已刪)</param>
/// <param name="startDate">開始時間</param>
/// <param name="endDate">結束時間</param>
/// <returns></returns>
public List<MessageEntity> GetMessageEntity(string sendUser, string receiveUser, string title, string messageType, DateTime? startDate, DateTime? endDate)
{
bool isDateSearch = startDate.HasValue && endDate.HasValue;
DirectSpecification<Message> commonSpecification = new DirectSpecification<Message>(msg =>
(string.IsNullOrEmpty(sendUser) ? true : msg.CerateUser == sendUser)
&& (string.IsNullOrEmpty(title) ? true : msg.Title.Contains(title))
&& (isDateSearch ? (msg.CreateDate >= startDate && msg.CreateDate <= endDate) : true)
&& msg.ReceiveUser.Equals(receiveUser));
MessageType messageTypeEnum = new MessageTypeIndexes()[messageType];
using (BonusEntities bonusEntities = new BonusEntities())
{
if (messageTypeEnum == MessageType.READ)
{
DirectSpecification<Message> readMsgSpec = new DirectSpecification<Message>(msg => msg.IsDel == false);
AndSpecification<Message> andSpecification = new AndSpecification<Message>(commonSpecification, readMsgSpec);
IEnumerable<Message> messageList = bonusEntities.Message.Where(andSpecification.SatisfiedBy());
return messageList.AsEnumerable().Select(msg =>
new MessageEntity()
{
TransactionNumber = msg.TransactionNumber,
Title = msg.Title,
MessageContent = msg.MessageContent.Length>50? msg.MessageContent.Substring(0, 50):msg.MessageContent,
CreateUser = msg.UserCreate.UerInfo != null ? msg.UserCreate.UerInfo.FirstOrDefault().Name : msg.UserCreate.UseNo,
CreateDate = msg.CreateDate.ToString(),
IsRead = msg.IsRead
}).ToList();
}
if (messageTypeEnum == MessageType.DELETE)
{
DirectSpecification<Message> delMsgSpec = new DirectSpecification<Message>(msg => msg.IsDel == true
&& msg.IsDestroy == false);
AndSpecification<Message> andSpecification = new AndSpecification<Message>(commonSpecification, delMsgSpec);
IQueryable<Message> messageList = bonusEntities.Message.Where(andSpecification.SatisfiedBy());
return messageList.AsEnumerable().Select(msg =>
new MessageEntity()
{
TransactionNumber = msg.TransactionNumber,
Title = msg.Title,
MessageContent = msg.MessageContent.Substring(0, 50),
CreateUser = msg.UserCreate.UerInfo != null ? msg.UserCreate.UerInfo.FirstOrDefault().Name : msg.UserCreate.UseNo,
CreateDate = msg.CreateDate.ToString(),
DelDate = msg.DelDate.HasValue? msg.DelDate.ToString():string.Empty
}).ToList();
}
return new List<MessageEntity>();
}
}
}
public enum MessageType
{
READ = 1,
DELETE = 2
}
public class MessageTypeIndexes
{
public Array MessageTypeEnumArray
{
get
{
return Enum.GetValues(typeof(MessageType));
}
}
public MessageType this[string msgType]
{
get
{
int messageType = int.Parse(msgType);
return (MessageType)MessageTypeEnumArray.GetValue(--messageType);
}
}
}好了，都是些查詢，沒什么可說的。
OK，我們現在就來看一下android的實現，我們先看一下前臺布局
<?xml version="1.0" encoding="utf-8"?> <ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:scrollbars="vertical" android:fadingEdge="none"> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:background="@color/red1"> <LinearLayout android:layout_height="wrap_content" android:layout_width="fill_parent" android:orientation="vertical" android:background="@color/teal1" android:layout_margin="1dp"> <TableLayout android:layout_height="wrap_content" android:layout_width="wrap_content" android:shrinkColumns="1" android:stretchColumns="1" android:background="@color/teal" android:layout_margin="2dp"> <TableRow> <TextView android:text="@string/labSendUser" android:textSize="8pt" android:gravity="right" android:textColor="@color/white"> </TextView> <EditText android:id="@+id/txtSendUser" android:drawableLeft="@drawable/userhint" android:singleLine="true" android:maxLength="30" android:textSize="7pt"></EditText> </TableRow> <TableRow> <TextView android:text="@string/labTitle" android:gravity="right" android:textSize="8pt" android:layout_marginLeft="10pt" android:textColor="@color/white"> </TextView> <EditText android:id="@+id/txtTitle" android:drawableLeft="@drawable/pencil" android:singleLine="true" android:maxLength="50"></EditText> </TableRow> <TableRow> <CheckBox android:id="@+id/chkIsDateCheck" android:text="@string/chkSendDate" android:textSize="8pt" android:gravity="center_vertical" android:layout_gravity="center_vertical" android:layout_span="2"></CheckBox> </TableRow> <TableRow> <TextView android:text="@string/chkBeginDate" android:textSize="8pt" android:textColor="@color/white"></TextView> <EditText android:id="@+id/txtStartDate" android:singleLine="true" android:editable="false" android:drawableRight="@drawable/calander"></EditText> </TableRow> <TableRow> <TextView android:text="@string/chkEndDate" android:textSize="8pt" android:textColor="@color/white"></TextView> <EditText android:id="@+id/txtEndDate" android:singleLine="true" android:editable="false" android:drawableRight="@drawable/calander"></EditText> </TableRow> </TableLayout> <LinearLayout android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content"> <ImageButton android:id="@+id/imgBtnSearch" android:src="@drawable/search" android:layout_weight="1" android:layout_width="wrap_content" android:layout_height="60dp" android:scaleType="centerInside" android:layout_marginLeft="5dp" android:layout_marginBottom="1dp"></ImageButton> <ImageButton android:id="@+id/imgBtnReset" android:layout_gravity="center_horizontal" android:layout_weight="1" android:src="@drawable/undo" android:layout_width="wrap_content" android:layout_height="60dp" android:scaleType="centerInside" android:layout_marginLeft="10dp" android:layout_marginRight="5dp" android:layout_marginBottom="1dp"></ImageButton> </LinearLayout> </LinearLayout> <TabHost android:id="@+id/tabhost" android:layout_width="fill_parent" android:layout_height="wrap_content"> <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TabWidget android:id="@android:id/tabs" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content" /> <FrameLayout android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="fill_parent"> <HorizontalScrollView android:layout_height="fill_parent" android:layout_width="fill_parent" android:scrollbarAlwaysDrawHorizontalTrack="false"> <TableLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:stretchColumns="0"> <TableRow> <bruce.controls.CustomScrollViewer android:id="@+id/gvMessageInfo" android:layout_width="fill_parent" android:layout_height="fill_parent"> </bruce.controls.CustomScrollViewer> </TableRow> </TableLayout> </HorizontalScrollView> </FrameLayout> </LinearLayout> </TabHost> </LinearLayout> </ScrollView>
還是使用嵌套布局，在最后我們發現了一個tabHost,是的，這個就是來實現tab頁的。我們看到tab頁中有一個一行一列的table，里面放了一個bruce.controls.CustomScrollViewer。這個東西其實是我從網上粘出來的一個用于顯示表格的自定義控件，這個寫的里面還是有些問題，我對其進行了一些修改。
今天主要不是針對這個，所以這個東西等下次我在講查看短消息功能的時候再說吧。
OK，我們先看一下查詢條件，發送人和標題就不看了，時間查詢的話，如果勾選了，就必須選擇日期
private Boolean CheckSearchCriteria(String startDateStr, String endDateStr)
throws ParseException {
if (this.chkIsDateCheck.isChecked()) {
if (startDateStr.length() == 0) {
this.ShowToast("請選擇開始日期！");
return false;
}
if (endDateStr.length() == 0) {
this.ShowToast("請選擇開始日期！");
return false;
}
SimpleDateFormat dateFormat = new SimpleDateFormat(
"yyyy-MM-dd HH:mm:ss");
Date startDate = dateFormat.parse(startDateStr + " 00:00:01");
Date endDate = dateFormat.parse(endDateStr + " 23:59:59");
if (startDate.after(endDate)) {
this.ShowToast("開始日期不能大于結束日期！");
return false;
}
}
return true;
}以前我們提示的時候都是使用Alert，現在的話，都是使用toast
private void ShowToast(String content) {
Toast toast = Toast.makeText(getApplicationContext(), content,
Toast.LENGTH_LONG);
toast.setGravity(Gravity.CENTER, 0, 0);
LinearLayout toastContentView = (LinearLayout) toast.getView();
ImageView imgToast = new ImageView(getApplicationContext());
imgToast.setAdjustViewBounds(true);
imgToast.setImageResource(R.drawable.alert);
toastContentView.addView(imgToast, 0);
toast.show();
}上次的時候我們選擇日期是使用Click事件，這次我們使用長按事件。
txtStartDate.setOnLongClickListener(new OnLongClickListener() {
public boolean onLongClick(android.view.View view) {
if (chkIsDateCheck.isChecked()) {
owner.ShowDatePicker(view);
}
return true;
}
});
txtEndDate.setOnLongClickListener(new OnLongClickListener() {
public boolean onLongClick(android.view.View view) {
if (chkIsDateCheck.isChecked()) {
owner.ShowDatePicker(view);
}
return true;
}
});如下是ShowDatePicker的代碼，這次將這個方法寫成公用的。
private void ShowDatePicker(final View view) {
Calendar calendar = Calendar.getInstance();
DatePickerDialog dialog = new DatePickerDialog(owner,
new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker dp, int year, int month,
int dayOfMonth) {
if (view instanceof EditText) {
((EditText) view).setText(year + "-" + month + "-"
+ dayOfMonth);
}
}
}, calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH),
calendar.get(Calendar.DAY_OF_MONTH));
dialog.show();
}OK，以上是查詢部分，接下來我們看一下查詢結果部分，先是構造tab頁。
private void InitTabHost() {
tabHost = (TabHost) this.findViewById(R.id.tabhost);
tabHost.setup();
TabSpec specMessageNew = tabHost.newTabSpec("tabMessageNew");
specMessageNew.setContent(R.id.gvMessageInfo);
specMessageNew.setIndicator("已讀/未讀", this.getResources().getDrawable(
R.drawable.emailread));
TabSpec specMessageOld = tabHost.newTabSpec("tabMessageOld");
specMessageOld.setContent(R.id.gvMessageInfo);
specMessageOld.setIndicator("已刪消息", this.getResources().getDrawable(
R.drawable.emaildel));
tabHost.addTab(specMessageNew);
tabHost.addTab(specMessageOld);
}在這里，我們加了兩個tab，setIndicator第一個參數是設置tab標題，第二個參數是設置tab圖標。
setContent是設置tab頁的內容，這里我們設置的是剛才上面介紹的自定義控件。
好的，我們最后看一下查詢部分，調用WebService代碼如下
private void SearchMessage() throws ParseException {
String startDateStr = this.txtStartDate.getText().toString().trim();
String endDateStr = this.txtEndDate.getText().toString().trim();
if (!this.CheckSearchCriteria(startDateStr, endDateStr))
return;
String title = txtTitle.getText().toString().trim();
String sendUser = txtSendUser.getText().toString().trim();
if (this.chkIsDateCheck.isChecked()) {
SimpleDateFormat dateFormat = new SimpleDateFormat(
"yyyy-MM-dd HH:mm:ss");
startDateStr = startDateStr + " 00:00:01";
endDateStr = endDateStr + " 23:59:59";
}
SoapObject response = this.GetMessageEntityList(title, sendUser,
startDateStr, endDateStr, (String.valueOf(tabHost
.getCurrentTab() + 1)));
HashMap<String, Object> map = null;
ArrayList<HashMap<String, Object>> mapList = new ArrayList<HashMap<String, Object>>();
for (int i = 0; i < response.getPropertyCount(); i++) {
SoapObject soapObj = (SoapObject) response.getProperty(i);
map = new HashMap<String, Object>();
map.put("Title", soapObj.getProperty("Title").toString());
map.put("MessageContent", soapObj.getProperty("MessageContent")
.toString());
map.put("CreateUser", soapObj.getProperty("CreateUser").toString());
map.put("CreateDate", soapObj.getProperty("CreateDate").toString());
Object isReadObj = soapObj.getProperty("IsRead");
Boolean isRead = Boolean.valueOf(isReadObj.toString());
map.put("IsOpen", isRead ? R.drawable.folderopen
: R.drawable.ckffolder);
mapList.add(map);
}
this.BinData(mapList);
}在這里我們拿到了webservice返回的數據，調用代碼如下
final static String NAMESPACE = "http://tempuri.org/"; final static String METHOD_NAME = "GetMessageEntity"; final static String SOAP_ACTION = "http://tempuri.org/GetMessageEntity"; final static String URL = main.baseIP + "/MessageMng.asmx?wsdl";
private SoapObject GetMessageEntityList(String title, String sendUser,
String startDate, String endDate, String messageType) {
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
PropertyInfo pi = new PropertyInfo();
pi.setName("sendUser");
pi.setType(String.class);
pi.setValue(sendUser);
request.addProperty(pi);
pi = new PropertyInfo();
pi.setName("receiveUser");
pi.setType(String.class);
pi.setValue(userNo);
request.addProperty(pi);
pi = new PropertyInfo();
pi.setName("title");
pi.setType(String.class);
pi.setValue(title);
request.addProperty(pi);
pi = new PropertyInfo();
pi.setName("messageType");
pi.setType(String.class);
pi.setValue(messageType);
request.addProperty(pi);
pi = new PropertyInfo();
pi.setName("startDate");
pi.setType(String.class);
pi.setValue(startDate);
request.addProperty(pi);
pi = new PropertyInfo();
pi.setName("endDate");
pi.setType(String.class);
pi.setValue(endDate);
request.addProperty(pi);
SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);
soapEnvelope.dotNet = true;
HttpTransportSE httpTS = new HttpTransportSE(URL);
soapEnvelope.bodyOut = httpTS;
soapEnvelope.setOutputSoapObject(request);// 設置請求參數
// new MarshalDate().register(soapEnvelope);
try {
httpTS.call(SOAP_ACTION, soapEnvelope);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (XmlPullParserException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
SoapObject result = null;
try {
result = (SoapObject) soapEnvelope.getResponse();
} catch (SoapFault e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return result;
}OK，這些代碼都是以前講過的，在這里就不多說了。我們主要看BinData這個方法
private void BinData(ArrayList<HashMap<String, Object>> mapList) {
String[] headers = new String[] {};
if (mapList.size() > 0) {
headers = mapList.get(0).keySet().toArray(headers);
}
gvMessage.setTableHeaders(this.TransferHeader(headers));
gvMessage.setTableCellMaxEms(5);
int[] imgColums = {1};
gvMessage.setTableheadColor(R.color.teal);
for (HashMap<String, Object> hm : mapList) {
gvMessage.addNewRow(hm.values().toArray(), imgColums);
}
}第一步先拿出列頭，再轉成漢字
private String[] TransferHeader(String[] headers) {
String[] header=new String[]{};
List<String> convertHeaderList = new ArrayList<String>();
for (int i = 0; i < headers.length; i++) {
if (headers[i] == "CreateUser") {
convertHeaderList.add("發送人");
}
if (headers[i] == "Title") {
convertHeaderList.add("標題");
}
if (headers[i] == "IsOpen") {
convertHeaderList.add("已讀/未讀");
}
if (headers[i] == "CreateDate") {
convertHeaderList.add("發送日期");
}
if (headers[i] == "MessageContent") {
convertHeaderList.add("消息內容");
}
}
return convertHeaderList.toArray(header);
}然后再循環設置行內容
for (HashMap<String, Object> hm : mapList) {
gvMessage.addNewRow(hm.values().toArray(), imgColums);
}這里我們循環ArrayList<HashMap<String,Object>>，然后往表格控件中加數據，第一個參數是內容，第二個參數是圖片內容所在的列的數組。OK，運行一下，查詢試試
通過查詢check之后，我們看看結果
還行吧，OK，今天就到這里，下節我將給大家介紹這個自定義控件和實現
