Public module designs:In software development process, it is often necessary to design some public modules, as database connection, Data storage, network transmission, format analysis processing etc., to improve program development speed, reduce code redundancy;Therefore, development system It is preceding to need to design such public module;

(1) database helps class:The system client is provided with database Or-der. db, mainly preserves the order industry of courier Business information, its data can update acquisition from server;Courier can conveniently check one's own business information, so as to Preferably complete task;Reading and writing local data base Or-der. db must be by the SQLiteOpenHelper of system, therefore can To inherit SQLiteOpenHelper base class, the database management function needed for add-on system, form convenient database and help Class DBHelper;

(2) order engine class:Managing the service order information of oneself needs to connect Order. db, the number read and write in order table According to, and carry out data processing by Hash table;Design an OrderProvider common class, realize the increasing of data, change, delete, Look into, the similar operations code in distinct program module can be avoided, reduce program redundancy;

(3) network transmission class:Realize that user logs in, manages the operation such as order, be required for connecting the webserver and database;If The common class HttpUtil. java of one network connection of meter and transmission complete this thousand business;Post modes can be selected to service Device sends request, judges network connection situation according to response results Result;

public static String qucryStringForPost(String url) {

HttpPost request = HttpUtil, getHttpPost(url);

String result = null;

try{

HttpResponse response = HttpUtil. getHttpResponse(request);

if(response. getStatusLine(). gctStatusCode()= =200) {

result = EntityUtils, toString(response. getEntity());

return result;

}

} catch (ClicntProtocolE xccption e) {

e. printStackTrace();

Result=" Network Abnormal!“;

return result;

} catch (IOExccption e) {

e. printStackTrace();

Result=" Network Abnormal!“;

return result;

}

return null;

}。

Login module designs:For the security of strengthening system, authentication must be carried out using the system, therefore log in Module is essential;Login process is by wireless network, user's job number and cipher authentication is carried out in background data base, rear Login user information will be used in the order management of face, can so accomplish that responsibility is clearly demarcated, work is rigorous;

Logging in basic procedure is:Defeated people user's job number and password, legitimacy certification is locally being carried out, clothes are submitted to after meeting rule Business device, is inquired about in background data base, if the user then enters people's system, otherwise provides miscue;

After logining successfully, user profile is preserved into configuration file, to be used in the order management below;

SharedPreferences pre=getSharedPreferences (" user_msg ", MODE_WORLD_ WRITEABLE);

SharedPreferences. Editor editor = pre. edit();

Editor, putString (" id ", id);

Editor, putString (" name ", name);

editor. commit()。

Main interface design:User can enter the main interface of people's system after logining successfully, main interface passes through a GridView Displaying, sub-component ImageView, each ImageView is set to represent One function in GridView, while Word is shown below ImageView, is easy to intuitivism apprehension, meets the design requirement at current mobile phone prevalence interface;To each ImageView establishes the monitor of an event, and corresponding function interface can be jumped to when clicking ImageView;Such as point " order to be sent " icon hit in system main interface, order module to be sent can be entered.

Order module designs:Order management module mainly includes order to be sent, assigns order, competition for orders order, is sent to order Deng;

(1) order module to be sent:" order to be sent " icon is clicked in the main interface of system, people's module can be entered;Module master To include following functions:1. show order to be sent:Sent with charge free by customized ListView components Real time displaying logistics order and be The sequence information sent with charge free is waited in system, upper row shows down single time and order status, below a line show Merchant name and Shipping address;2. more New function:Again order list is refreshed, display waits the order sent with charge free;3. rob single function:Order A kind of acquisition modes, can selective competition for orders in the order list sent with charge free is waited;If competition for orders success, the sequence information of competition for orders It will be shown in competition for orders order list below;

Client sends request in a manner of Post by the sequence information of selection to server, is sentenced by returning result result It is disconnected that whether competition for orders is successful;

String qucryString =“id=“+selection. get(i)+“&op_id=“+oplD;

String url = HttpUtil. BASE_URL+“scrvlet/ModifyD-paiScrvlet?" + queryString;

String result= HttpUtil, queryStringForPost(url);

Toast. makeText (DpaiActivity. this, result, Toast. LENGTH_LONG) show ();

Server receives request, and obtains the required parameter of client;If it can be sent " competition for orders success " to client with competition for orders Printed words information;

String id = request. getParameter(“id");

String op_id = request. getParameter( "op_id");

Dao. ModifyDpai (id, op_id);

Out, println (" competition for orders success!“)

(2) order module is assigned:Another acquisition modes that order is order are assigned, in addition to competition for orders mode obtains, also have public affairs Take charge of the order taking responsibility assigned daily;The order that can check that company specifies me to send with charge free on the same day online by assigning order module is believed Breath, while the sequence information is saved in the local data base of mobile phone, in order to check;

(3) competition for orders order module:Rob single function to realize in order module to be sent, the module category management module, manage and waiting to send The sequence information obtained in order by competition for orders mode, and businessman is completed according to sequence information and takes single and delivery;

The sequence information obtained by competition for orders also preserves portion into local SQLite databases in addition to submitting server, can To inquire about and be shown with list mode in the module in the local database;

String state=" competition for orders ";

Db=this. openOrCreateDatabase (" Order. db ", MODE_PRIVATE, null);

Cursor=db. query (" OrderTbl ", null, " op_id likeAnd order_state like ", new String [] opID, state }, null, null, " order_timedesc ");

cursor, moveToFirst();

MyAdapter ad=new MyAdapter (this, R. layout. list_style, cursor,

New String [] " order_time ", " order_state ", " s_name ", " b_add " },

New int [] { R. id. textView1, R. id. textView2, R. id. textView3, R. id. textView5;list. setAdapter(ad)

(4) it is sent to order module:The sequence information that management has been completed in person, the work of oneself can be counted or checked with time segment Make achievement;The sequence information of completion needs to be committed to network data base, while updates local data base;

(5) other modules:Including system setting, Password Management, cancellation system, log off;At the beginning of mainly realizing local data base Beginningization, the modification of employee's password, system log in and exited again whole system.
