這篇文章主要為大家詳細(xì)介紹了Android實(shí)現(xiàn)機(jī)房座位預(yù)約系統(tǒng)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了Android實(shí)現(xiàn)預(yù)約系統(tǒng)的具體代碼，供大家參考，具體內(nèi)容如下

 

 

這周要去武漢開(kāi)會(huì)，下周項(xiàng)目就得用上，所以，比較緊。加上導(dǎo)師不懂Android開(kāi)發(fā)，只要開(kāi)會(huì)就改需求，/(ㄒoㄒ)/~~反正他說(shuō)先讓學(xué)校用著，移動(dòng)端和服務(wù)器的開(kāi)發(fā)就給了兩周時(shí)間。所以功能實(shí)現(xiàn)的比較簡(jiǎn)單，但代碼做的比較容易擴(kuò)展，都留了接口，后面更新起來(lái)也好做一些。通過(guò)這個(gè)工程，對(duì)Struts2的攔截器有了一些新體會(huì)。隨著項(xiàng)目變大代碼量變多，自然而然就會(huì)想起用一些設(shè)計(jì)模式了。不然代碼根本沒(méi)辦法看。

整體是4個(gè)fragment，每個(gè)fragment里都有課程表的布局，課程可以從服務(wù)器傳過(guò)來(lái)動(dòng)態(tài)生成。其實(shí)很多都可以復(fù)用的布局，為了代碼結(jié)構(gòu)清晰，都分開(kāi)寫(xiě)了。不然需要加控制器，調(diào)試起來(lái)心累。寫(xiě)的不好，還請(qǐng)大家多指教。做的還不完善，弄完以后再傳上來(lái)。

Application里對(duì)數(shù)據(jù)進(jìn)行持久化，這么做發(fā)現(xiàn)程序變得比較容易控制了。

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為 未登錄
  * 1為登錄
  */
 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); // 初始化全局變量
  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;
 }

}

做注冊(cè)時(shí)的邏輯判斷，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(), "密碼只能為6位數(shù)字！");
    }

  if (cancel) {
   ToastUtils.MyToast(getApplicationContext(), "輸入有誤，請(qǐng)從新輸入！");
   focusView.requestFocus();
   } else {
   //...這里做的網(wǎng)絡(luò)請(qǐng)求
   // TODO signup 提交服務(wù)器Get請(qǐng)求
   // 符合接口規(guī)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<String>() {

    @Override
    public void onSuccess(ResponseInfo<String> responseInfo) {
     Log.i("tag", "============success============"+responseInfo.result);
     ToastUtils.MyToast(getApplicationContext(), responseInfo.result);
     if(responseInfo.result.equals("success")){
    //注冊(cè)成功，自動(dòng)實(shí)現(xiàn)登錄
     app.setLogin(true);
     app.setName(username);
    //更新UI
     Message m = Message.obtain();
     m.what=1;
     handler.sendMessage(m);
     ToastUtils.MyToast(getApplicationContext(), "注冊(cè)成功，學(xué)號(hào)："+username);
     }else{
     ToastUtils.MyToast(getApplicationContext(), responseInfo.result);
     }
    dialog.dismiss();
   }

  @Override
  public void onFailure(HttpException error, String msg) {
  ToastUtils.MyToast(getApplicationContext(), msg);
  dialog.dismiss();
  }
 });
}

以上就是本文的全部?jī)?nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持腳本之家。
