6.1、 项目实施6.4.1、 引导界面6.4.1、 引导界面运行程序时的过渡界面,程序的界面布局如下图所示:程序界面布局代码如下:程序代码如下：/* * 过渡页面 * */public class SplashActivity extends BaseActivityprivate Handler mHandler = new Handler();protected final int SPLASH_TIME = 500; public void onCreate(Bundle savedInstanceState) super.onCreate(savedInstanceState); /setFullScreen(); View view=View.inflate(this,R.layout.activity_splash, null);setContentView(view);Animation animation=AnimationUtils.loadAnimation(this, R.anim.alpha);animation.setAnimationListener(new AnimationListener() Overridepublic void onAnimationStart(Animation arg0) Overridepublic void onAnimationRepeat(Animation arg0) Overridepublic void onAnimationEnd(Animation arg0) mHandler.postDelayed(new Runnable() Overridepublic void run() goMain();, SPLASH_TIME);); view.startAnimation(animation); protected void onResume() super.onResume();private void goMain() MainApplication.getInstance().addActivity(this);startActivity(new Intent(this,LoginActivity.class); ;SuppressWarnings(unused)private void setFullScreen() getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);SuppressWarnings(unused)private void quitFullScreen() final WindowManager.LayoutParams attrs = getWindow().getAttributes(); attrs.flags &= (WindowManager.LayoutParams.FLAG_FULLSCREEN); getWindow().setAttributes(attrs); getWindow().clearFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);6.4.2、 登录界面实现帐号和密码输入文本框、实现登录按键功能、实现密码记录功能和自动登录功能.页面布局如下图所示:当用户输入帐号和密码，点击登录按键时，系统读取账号和密码文本框信息，并把账号和密码信息经网络传输给智能网关, 与智能网关中的数据库中的账号和密码数据信息进行比对，如果账号和密码同时存在于智能网关中的数据库中，则允许用户登录系统。如果账号或密码不正确，则根据返回的标记码的不同，提示“账号不存在”或“密码不正确”。当用户选中“保存密码”时，系统会把“账号和密码”保存在系统相关的配置文件中，当下次再登录系统时，则不需要再次输入“账号和密码”。如果用户只选中“自动登录”时，则系统会保存“账号”和“密码”，下次自动登录系统。程序的界面布局代码如下： 程序代码如下：/* * 用户登录 * */public class LoginActivity extends BaseActivity implements OnClickListener /* * 用户信息处理对象 * */private UserDAO mUserDAO;/* * 异步登录对象 * */private LoginHttpRequestTask mLoginHttpRequestTask=null;/* * 正在登录的对话框 * */private ProgressDialog mProgressDialog=null;public void onCreate(Bundle savedInstanceState) super.onCreate(savedInstanceState); setContentView(R.layout.activity_login); mUserDAO=new UserDAO(this); MainApplication.getInstance().addActivity(this); findViewById(R.id.btn_login).setOnClickListener(this); findViewById(R.id.tv_demo).setOnClickListener(this); findViewById(R.id.tv_config).setOnClickListener(this); Overridepublic void onBackPressed() / TODO Auto-generated method stubsuper.onBackPressed(); Overridepublic boolean onKeyDown(int keyCode, KeyEvent event) / TODO Auto-generated method stubif(keyCode = KeyEvent.KEYCODE_BACK) exitBy2Click(); return false; Overridepublic void onClick(View v) / TODO Auto-generated method stubswitch(v.getId()case R.id.btn_login:EditText edt_userName=(EditText)findViewById(R.id.edt_userName);EditText edt_password=(EditText)findViewById(R.id.edt_password);mLoginHttpRequestTask=new LoginHttpRequestTask();mLoginHttpRequestTask.execute(edt_userName.getText().toString(),edt_password.getText().toString(); break;case R.id.tv_demo: break;case R.id.tv_config:startActivity(new Intent(LoginActivity.this,ConfigActivity.class);break;private static Boolean isExit = false;/* * 双击后退按钮退出 * */private void exitBy2Click() Timer tExit = null;if (isExit = false) isExit = true; Toast.makeText(this, getResources().getString(R.string.exit_dialog_message), Toast.LENGTH_SHORT).show();tExit = new Timer(); tExit.schedule(new TimerTask() Overridepublic void run() isExit = false; , 2000); else MainApplication.getInstance().exit();/* * 登录异步操作类 * */private class LoginHttpRequestTask extends AsyncTask Overrideprotected void onPreExecute() / TODO Auto-generated method stubsuper.onPreExecute(); /mProgressDialog = ProgressDialog.show(LoginActivity.this, 登录, 正在登录中., false, true, null);mProgressDialog = ProgressDialog.show(LoginActivity.this, getResources().getString(R.string.login),getResources().getString(R.string.loading), false, true, null);Overrideprotected ControlResultJson doInBackground(String. params) / TODO Auto-generated method stubif(params!=null¶ms.length1) return mUserDAO.login(params0, params1);return null; protected void onPostExecute(ControlResultJson result) if(result!=null)if(result.code=0)MainConfig.getInstance(getApplicationContext().setSessionId(result.result.sessionId);MainConfig.getInstance(getApplicationContext().save();startActivity(new Intent(LoginActivity.this,MainActivity.class);else Toast.makeText(getBaseContext(), result.msg, Toast.LENGTH_SHORT).show();elseToast.makeText(getBaseContext(), unknow erro!, Toast.LENGTH_SHORT).show();mProgressDialog.dismiss();6.4.3、 主界面实现“返回”及7个图示功能，页面布局如下图所示：“返回”键的作用返回上一级页面，“情景模式”示图的作用进入到情景模式页面，其他示图功能类似。程序的界面布局代码如下： 程序代码如下：/* * 主界面 * */public class MainActivity extends BaseActivity private TextView titlebar_left;private TextView titlebar_title;public void onCreate(Bundle savedInstanceState) super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); MainApplication.getInstance().addActivity(this); titlebar_left = (TextView) findViewById(R.id.titlebar_left); titlebar_left.setOnClickListener(new View.OnClickListener() Overridepublic void onClick(View v) onBackPressed(); );titlebar_title = (TextView) findViewById(R.id.titlebar_title); titlebar_title.setText(R.string.app_name); GridView gridView = (GridView) findViewById(R.id.gdv_main); ArrayListHashMap lstImageItem = new ArrayListHashMap(); HashMap map = new HashMap(); map.put(ItemImage, R.drawable.icon_model);map.put(ItemText, getResources().getString(R.string.title_models); lstImageItem.add(map); map = new HashMap(); map.put(ItemImage, R.drawable.icon_room);map.put(ItemText, getResources().getString(R.string.title_myroom);

lstImageItem.add(map); SimpleAdapter saImageItems = new SimpleAdapter(this, lstImageItem, R.layout.view_squared_item, new String ItemImage,ItemText, new int R.id.itemImage,R.id.itemText); gridView.setAdapter(saImageItems); gridView.setOnItemClickListener(new OnItemClickListener() Overridepublic void onItemClick(AdapterView arg0, View arg1, int arg2,long arg3) / TODO Auto-generated method stubswitch(arg2)case 0:startActivity(new Intent(MainActivity.this,ModelListActivity.class);break;case 1:startActivity(new Intent(MainActivity.this,RoomListActivity.class);break;case 2:startActivity(new Intent(MainActivity.this,FunctionListActivity.class);break;case 3:startActivity(new Intent(MainActivity.this,VideoActivity.class);break;case 4:startActivity(new Intent(MainActivity.this,TimingTaskActivity.class);break;case 5:startActivity(new Intent(MainActivity.this,AlarmRecordActivity.class);break;case 6:startActivity(new Intent(MainActivity.this,ConfigActivity.class);break;
