机房座位系统C语言,Android实现机房座位预约系统

本文实例为大家分享了Android实现预约系统的具体代码，供大家参考，具体内容如下

这周要去武汉开会，下周项目就得用上，所以，比较紧。加上导师不懂Android开发，只要开会就改需求，/(ㄒoㄒ)/~~反正他说先让学校用着，移动端和服务器的开发就给了两周时间。所以功能实现的比较简单，但代码做的比较容易扩展，都留了接口，后面更新起来也好做一些。通过这个工程，对Struts2的拦截器有了一些新体会。随着项目变大代码量变多，自然而然就会想起用一些设计模式了。不然代码根本没办法看。

整体是4个fragment，每个fragment里都有课程表的布局，课程可以从服务器传过来动态生成。其实很多都可以复用的布局，为了代码结构清晰，都分开写了。不然需要加控制器，调试起来心累。写的不好，还请大家多指教。做的还不完善，弄完以后再传上来。

Application里对数据进行持久化，这么做发现程序变得比较容易控制了。

Application

package com.example.myapplication;

import android.app.Application;

import android.content.SharedPreferences;

import android.content.SharedPreferences.Editor;

public class CustomApplication extends Application {

public static final String serverAddress = "http://192.168.1.119";

// public static final String serverAddress = "http://10.187.86.63";

public static final String serverPort = "8080/Person_proj/upload";

// public static final String serverPort = "8000";

private static final String DEFAULT_NAME = "";

private static final String DEFAULT_ID = "-1";

private String name;

private String id;

private String room;

private String myOrder="NULL";

private boolean isLogin = false;

public boolean isLogin() {

SharedPreferences sp = getSharedPreferences("status", MODE_PRIVATE);

return sp.getBoolean("islogin", false);

}

/**

* 0为 未登录

* 1为登录

*/

public void setLogin(boolean isLogin) {

SharedPreferences sp = getSharedPreferences("status", MODE_PRIVATE);

Editor edit = sp.edit();

edit.putBoolean("islogin", isLogin);

edit.commit();

}

private int version;

public int getVersion() {

SharedPreferences sp = getSharedPreferences("status", MODE_PRIVATE);

return sp.getInt("version",0);

}

public void setVersion(int version) {

SharedPreferences sp = getSharedPreferences("status", MODE_PRIVATE);

Editor edit = sp.edit();

edit.putInt("version",version);

edit.commit();

}

public String getMyOrder() {

SharedPreferences sp = getSharedPreferences("status", MODE_PRIVATE);

return sp.getString("order","NULL");

}

public void setMyOrder(String myOrder) {

SharedPreferences sp = getSharedPreferences("status", MODE_PRIVATE);

Editor edit = sp.edit();

edit.putString("order",myOrder);

edit.commit();

}

@Override

public void onCreate() {

super.onCreate();

setName(DEFAULT_NAME); // 初始化全局变量

setId(DEFAULT_ID);

}

public void setName(String name) {

SharedPreferences sp = getSharedPreferences("status", MODE_PRIVATE);

Editor edit = sp.edit();

edit.putString("name", name);

edit.commit();

}

public String getName() {

SharedPreferences sp = getSharedPreferences("status", MODE_PRIVATE);

return sp.getString("name", "none");

}

public String getId() {

return id;

}

public void setId(String id) {

this.id = id;

}

public void setRoom(String room) {

this.room = room;

}

public String getRoom() {

return room;

}

}

做注册时的逻辑判断，onClick事件里：

boolean cancel = false;

View focusView = null;

String id = builder.getUserId().trim();

String password = builder.getPassword().trim();

String passwordConfirm = builder.getPasswordConfirm().trim();

final String username = builder.getUsername().trim();

// Check for a valid password.

if (TextUtils.isEmpty(password)) {

cancel = true;

focusView = builder.getStuPwdEditText();

}

// Check for a valid password.

if (TextUtils.isEmpty(passwordConfirm)) {

cancel = true;

focusView = builder.getStuPwdConfirmEditText();

}

if (!password.equals(passwordConfirm)) {

cancel = true;

focusView = builder.getStuPwdEditText();

}

// Check for a valid Id.

if (TextUtils.isEmpty(id)) {

cancel = true;

focusView = builder.getStuIdEditText();

}

// Check for a valid username.

if (TextUtils.isEmpty(username)) {

cancel = true;

focusView = builder.getStuNameEditText();

}

if(!MatchUtils.match(password)||!MatchUtils.match(passwordConfirm)){

cancel = true;

focusView = builder.getStuPwdEditText();

ToastUtils.MyToast(getApplicationContext(), "密码只能为6位数字！");

}

if (cancel) {

ToastUtils.MyToast(getApplicationContext(), "输入有误，请从新输入！");

focusView.requestFocus();

} else {

//...这里做的网络请求

// TODO signup 提交服务器Get请求

// 符合接口规范

final String url =app.serverAddress+":"+app.serverPort+"?"+"action=signin"+"&"+"username="+username+"&"+"oldpassword="+password;

HttpUtils http = new HttpUtils();

http.send(HttpMethod.GET, url, new RequestCallBack() {

@Override

public void onSuccess(ResponseInfo responseInfo) {

Log.i("tag", "============success============"+responseInfo.result);

ToastUtils.MyToast(getApplicationContext(), responseInfo.result);

if(responseInfo.result.equals("success")){

//注册成功，自动实现登录

app.setLogin(true);

app.setName(username);

//更新UI

Message m = Message.obtain();

m.what=1;

handler.sendMessage(m);

ToastUtils.MyToast(getApplicationContext(), "注册成功，学号："+username);

}else{

ToastUtils.MyToast(getApplicationContext(), responseInfo.result);

}

dialog.dismiss();

}

@Override

public void onFailure(HttpException error, String msg) {

ToastUtils.MyToast(getApplicationContext(), msg);

dialog.dismiss();

}

});

}
