Mono的简单例子

一直对移动端开发有些兴趣,但苦于不会Java,好在终于找到了个好玩的。

安装方法略了,先建立一个玩玩

Mono的简单例子

不多说,贴代码了,需要注意的只有些JAVA和C#写法不太一样的地方,不细介绍了,因为没什么经验,乱试的,所以也没什么规范,随便看看就好

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text; using Android.App;
using Android.Content;
using Android.OS;
using Android.Runtime;
using Android.Views;
using Android.Widget;
using Java.Util; namespace AndroidHotelServiceTest
{
[Activity(Label = "My Activity")]
public class ActivityCalendar : Activity
{
protected override Dialog OnCreateDialog(int id)
{
if (id == 1)
{
return new DatePickerDialog(this, new DDialogLisetener(this), 2013, 11, 11);
}
return base.OnCreateDialog(0);
} protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
// Create your application here
SetContentView(Resource.Layout.CalendarView);
Button button = FindViewById<Button>(Resource.Id.btClose);
button.Click += delegate
{
Intent intent = new Intent();
intent.SetClass(this, typeof(ActivityHotel));
StartActivity(intent);
}; ShowDialog(1); }
} public class DDialogLisetener : DatePickerDialog.IOnDateSetListener
{
private Context _context;
public DDialogLisetener(Context context)
{

} public void OnDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth)
{
String sDayOfWeek = getDayOfWeek(year, monthOfYear, dayOfMonth);
//Toast.makeText(CreateParty.this, "sdf", Toast.LENGTH_LONG).show();
int m_nYear = year;
int m_nMonth = monthOfYear + 1;
int m_nDay = dayOfMonth;
Toast.MakeText(_context, "ddd", ToastLength.Long).Show();

} private string getDayOfWeek(int tmpYear, int tmpMonth, int tmpDay)
{
String myWeek = null;
String sYear = tmpYear.ToString();
// 取年的后两位
String sYearTwo = sYear.Substring(sYear.Length - 2); int y = tmpYear; int m = tmpMonth + 1;
int c = 20;
int d = tmpDay;
int w = (y + (y / 4) + (c / 4) - 2 * c
+ (26 * (m + 1) / 10) + d - 1) % 7; switch (w)
{
case 0:
myWeek = "日";
break;
case 1:
myWeek = "一";
break;
case 2:
myWeek = "二";
break;
case 3:
myWeek = "三";
break;
case 4:
myWeek = "四";
break;
case 5:
myWeek = "五";
break;
case 6:
myWeek = "六";
break;
default:
break;
}
return myWeek; } public void Dispose()
{
this.Dispose();
} public IntPtr Handle
{
get { return IntPtr.Zero; }
}
}
}

  参考了不少网上的代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text; using Android.App;
using Android.Content;
using Android.OS;
using Android.Runtime;
using Android.Views;
using Android.Widget;
using Android.Media;
using Android.Content.Res;
using Java.IO; namespace AndroidHotelServiceTest
{
public class BeepManager
{
private static Activity m_CurrentActivity;
private static MediaPlayer m_MediaPlayer = null; private static MediaPlayer BuildMediaPlayer(Context context)
{
MediaPlayer player = new MediaPlayer();
player.SetAudioStreamType(Android.Media.Stream.Music);
player.Completion += new EventHandler(mediaplayer_Completion); AssetFileDescriptor assetfiledescriptor = context.Resources.OpenRawResourceFd(0x7f040000);
try
{
player.SetDataSource(assetfiledescriptor.FileDescriptor, assetfiledescriptor.StartOffset, assetfiledescriptor.Length);
assetfiledescriptor.Close();
player.SetVolume(0.1F, 0.1F);
player.Prepare();
m_MediaPlayer = player;
}
catch (IOException ioexception)
{
player = null;
} return player;
} static void mediaplayer_Completion(object sender, EventArgs e)
{
m_MediaPlayer.SeekTo(0);
} public static void PlayBeepSound(Activity activity)
{
m_CurrentActivity = activity;
if (m_MediaPlayer == null)
{
m_MediaPlayer = BuildMediaPlayer(m_CurrentActivity);
}
m_MediaPlayer.Start();
} public static void Stop()
{
if (m_MediaPlayer != null)
{
m_MediaPlayer.Stop();
m_MediaPlayer = null;
}
} //private void prepareToPlay()
//{
// try
// {
// //获取当前音频流的路径后我们需要通过MediaPlayer的setDataSource来设置,然后调用prepareAsync()来完成缓存加载
// String path = pathList.get(currPosition);
// player.setDataSource(path);
// //之所以使用prepareAsync是因为该方法是异步的,因为访问音频流是网络操作,在缓冲和准备播放时需要花费
// //较长的时间,这样用户界面就可能出现卡死的现象
// //该方法执行完成后,会执行onPreparedListener的onPrepared()方法。
// player.prepareAsync(); // }
// catch (IllegalArgumentException e)
// {
// // TODO Auto-generated catch block
// e.printStackTrace();
// }
// catch (IllegalStateException e)
// {
// // TODO Auto-generated catch block
// e.printStackTrace();
// }
// catch (IOException e)
// {
// // TODO Auto-generated catch block
// e.printStackTrace();
// }
//}
}
}

调用WCF验证登陆

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text; using Android.App;
using Android.Content;
using Android.OS;
using Android.Runtime;
using Android.Views;
using Android.Widget;
using System.ServiceModel;
using System.Threading; namespace AndroidHotelServiceTest
{
[Activity(Label = "登陆", MainLauncher = true)]
public class ActivityLogin : Activity
{
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
SetContentView(Resource.Layout.Login);
// Create your application here Button button = FindViewById<Button>(Resource.Id.login);
EditText txtUser = FindViewById<EditText>(Resource.Id.edtuser);
EditText txtPassword = FindViewById<EditText>(Resource.Id.edtpsd); button.Click += delegate
{
Login(txtUser.Text, txtPassword.Text);
};
} public void Login(string user, string password)
{
BasicHttpBinding binding = new BasicHttpBinding(BasicHttpSecurityMode.None);
var timeout = new TimeSpan(0, 1, 0);
binding.SendTimeout = timeout;
binding.OpenTimeout = timeout;
binding.ReceiveTimeout = timeout; IHotelService service = ChannelFactory<IHotelService>.CreateChannel(binding,
new EndpointAddress("http://172.25.16.50:90/HotelService.svc"));
string loginUser = service.Login(user, password);
if (!string.IsNullOrEmpty(loginUser))
{
Intent intent = new Intent();
intent.SetClass(this, typeof(ActivityHotel));
intent.PutExtra("User", user);
StartActivity(intent);
}
}
}
}

总之,大概就这样了,页面布局什么的也没什么特别的。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:minWidth="25px"
android:minHeight="25px">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="账号:" />
<EditText
android:layout_width="240dip"
android:layout_height="wrap_content"
android:text="aaa"
android:id="@+id/edtuser" />
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="密码:" />
<EditText
android:layout_width="240dip"
android:layout_height="wrap_content"
android:password="true"
android:id="@+id/edtpsd" />
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:orientation="vertical">
<CheckBox
android:id="@+id/checkbox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="记住密码" />
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<Button
android:id="@+id/login"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:text="登录" />
</LinearLayout>
</LinearLayout>
</LinearLayout>

至于服务端,就是VS自动生成的代码加了一个登陆判断而已

[ServiceContract]
public interface IHotelService
{
[OperationContract]
string Login(string user, string password);
}
