例子:Alarm Clock with voice Commands Sample

通过本例子学习:

  1. 如何使用自定义字体文件(.TTF)
  2. 如何播放声音
  3. 动画的使用
  4. Speech
  5. 设置闹铃
  6. 应用 设置 数据存储到IsolatedStorage

 

 

  • 如何使用自定义字体文件(.TTF)
<TextBlock x:Name="TimeBlock" HorizontalAlignment="Center"   

FontFamily="/AlarmClockWithVoice;component/Fonts/Fonts.zip#Quartz MS" 

Margin="89,272,87,256" FontSize="60">

字体文件BuildAction为Resource的使用方式:
(FontFamily="/AlarmClockWithVoice;component/Fonts/Fonts.zip#Quartz MS")
字体文件BuildAction为Content的使用方式:
(FontFamily="/Assets/Fonts/Fonts.zip#Quartz MS")

 

注意: Windows Phone 显示应用指定的 FontFamily 中的文本。如果字符不受 FontFamily 支持,或者应用未指定 FontFamily,Windows Phone 将基于字符和用于显示文本的框架元素的 xml:lang 选择一种字体。

 

  • 如何播放声音

以流的方式读取本地文件,并创建SoundEffect对象。

            StreamResourceInfo info = App.GetResourceStream(new Uri("Audio/alarm.wav", UriKind.Relative));
            Microsoft.Xna.Framework.Audio.SoundEffect alarm = SoundEffect.FromStream(info.Stream);

 播放,停止等操作,当前SoundEffect对象的状态SoundState 可以通过 属性State获取:

          this.alarmSound.Play();
                }
                else if (alarmSound.State == SoundState.Playing)
                {
                    this.alarmSound.Stop();
                }
            }
            else if (alarmSound.State == SoundState.Playing)
            {
                this.alarmSound.Stop();
            }

 

 

  • 动画的使用

小时指针 图片的动画:

<Image x:Name="hourHand" HorizontalAlignment="Left" Height="20" Margin="255,203,0,0" 

Grid.Row="1" VerticalAlignment="Top" Width="99" Source="/Images/hourHand.jpg" 

RenderTransformOrigin="0.097,0.5">
    <Image.RenderTransform>
        <CompositeTransform ScaleX="1.5" ScaleY="1.5" TranslateX="-20.15"/>
    </Image.RenderTransform>
</Image>

主要是通过“UIElement.RenderTransform”来实现的: public Transform RenderTransform { get; set; } 要使用多个动画效果,可以使用TransformGroup把多个动画包含其中。

7种变换分别是:

  1、TransLateTransForm 移动位置,包含水平移动和垂直移动

  2、ScaleTransform 缩放变换 对UI进行放大缩小 包含X轴上的缩放和Y轴上的缩放

  3、RotateTransform 旋转 根据定义的旋转点设置角度进行旋转

  4、SkewTransform 对UI进行一定角度的倾斜

  5、MatrixTransfrom 矩阵变换,一句标准矩阵表示的变换

  6、TransformGroup 复合变换按照指定顺序将多个变换复合为一个变换

  7、CompositeTransform 组合变换按照固定顺序组合一系列变换

 

  • Speech

语音命令:

1. 右键工程,新 添加 “语音命令项”

    <Command Name="alarmTimeSet">
      <Example>Set alarm to 7:30 am.</Example>
      <ListenFor>Set alarm to {hour} {minute} {ampm}</ListenFor>
      <Feedback>Setting the alarm clock</Feedback>
      <Navigate Target="MainPage.xaml"/>
    </Command>

    <PhraseList Label="hour">
      <Item>1</Item>
      <Item>2</Item>
      <Item>3</Item>
      <Item>4</Item>
      <Item>5</Item>
      <Item>6</Item>
      <Item>7</Item>
      <Item>8</Item>
      <Item>9</Item>
      <Item>10</Item>
      <Item>11</Item>
      <Item>12</Item>
    </PhraseList>

2. 初始化语音命令:

                    Uri uri = new Uri("ms-appx:///voicecommands.xml", UriKind.Absolute);
                    await Windows.Phone.Speech.VoiceCommands.VoiceCommandService.InstallCommandSetsFromFileAsync(uri);

 

语音识别读取:

1. 初始化语音识别相关属性:

using Windows.Phone.Speech.Recognition; 
using Windows.Phone.Speech.Synthesis; 


            Speech.recognizer = new SpeechRecognizer();
            Speech.synthesizer = new SpeechSynthesizer();
            Speech.recognizerUI = new SpeechRecognizerUI();

            // Sets the en-US male voice.
            IEnumerable<VoiceInformation> enUSMaleVoices = from voice in InstalledVoices.All
                                    where voice.Gender == VoiceGender.Male
                                    && voice.Language == "en-US"
                                    select voice;

            Speech.synthesizer.SetVoice(enUSMaleVoices.ElementAt(0));


2. 朗读文本:

                        await Speech.synthesizer.SpeakTextAsync("Alarm is now set for "
                            + Settings.alarmTime.Value.Hours + " " + Settings.alarmTime.Value.Minutes);


 

  • 设置闹铃

1. 初始化设置闹钟:

using Microsoft.Phone.Scheduler;

public static Alarm alarm;

            Clock.alarm = new Alarm("alarm");
            Clock.alarm.ExpirationTime = DateTime.MaxValue;
            Clock.alarm.RecurrenceType = RecurrenceInterval.Daily;
            Clock.alarm.Sound = new Uri("Audio/alarm.wav", UriKind.Relative);
            Clock.alarm.Content = "Alarm ringing!";

 

2. 添加到SchduleActionService,一个专门用于管理计划任务的类:

ScheduledActionService.Add(Clock.alarm);

3.根据用户操作输入,设定时间:
参数为 年月日时分秒, 1 表示everyday。

Clock.alarm.BeginTime = new DateTime(1, 1, 1, hours, minutes, 0);

 

 

  •  应用 设置 数据存储到IsolatedStorage
using System.IO.IsolatedStorage;

public class StoredItem<T>
    {
        private T value;
        private T defaultValue;
        private string name;
        private bool needRefresh;

        public StoredItem(string _name, T _defaultValue)
        {
            this.name = _name;
            this.defaultValue = _defaultValue;

            // If isolated storage doesn't have the value stored yet
            if (!IsolatedStorageSettings.ApplicationSettings.TryGetValue(this.name, out this.value))
            {
                this.value = _defaultValue;
                IsolatedStorageSettings.ApplicationSettings[this.name] = _defaultValue;
            }

            this.needRefresh = false;
        }

        public T Value
        {
            get
            {
                if (this.needRefresh)
                {
                    if (!IsolatedStorageSettings.ApplicationSettings.TryGetValue(this.name, out this.value))
                    {
                        IsolatedStorageSettings.ApplicationSettings[this.name] = this.defaultValue;
                        this.value = this.defaultValue;
                    }
                    this.needRefresh = false;
                }

                return this.value;
            }
            set
            {
                if (this.value.Equals(value))
                    return;

                // Store the value in isolated storage.
                IsolatedStorageSettings.ApplicationSettings[this.name] = value;
                this.needRefresh = true;
            }
        }

        public T DefaultValue
        {
            get
            {
                return this.defaultValue;
            }
        }

        public string Name
        {
            get
            {
                return this.name;
            }
        }

        public override string ToString()
        {
            return this.name
                + " with value: " + this.value.ToString()
                + ", default value: " + this.defaultValue.ToString();
        }

        public void ForceRefresh()
        {
            this.needRefresh = true;
        }
    }
