与众不同 windows phone (24) - Input（输入）之软键盘类型, XNA 方式启动软键盘, UIElement 的 Touch 相关事件, 触摸涂鸦

作者：webabcd

介绍
与众不同 windows phone 7.5 (sdk 7.1) 之输入

  • 指定软键盘的类型
  • XNA 方式启动软键盘，并获取用户输入的信息
  • UIElement 的 Touch 相关事件
  • 涂鸦板

示例
1、演示如何指定软键盘的类型

    shell:SystemTray.IsVisible="True">

    <Grid x:Name="LayoutRoot" Background="Transparent">

        <StackPanel Orientation="Vertical">

            <!--SIP 包含数字和小数点，按住句号键可以显示“.,-”-->

            <TextBox InputScope="Number" />

            <!--SIP 按“123”键切换到电话号码键盘，按住句号键可以显示“.,-”-->

            <TextBox InputScope="NameOrPhoneNumber" />

            <!--SIP 默认显示数字和符号键盘-->

            <TextBox InputScope="CurrencyChinese" />

            <!--SIP 显示电话拨号键盘-->

            <TextBox>

                <TextBox.InputScope>

                    <InputScope>

                        <InputScopeName NameValue="TelephoneNumber" />

                    </InputScope>

                </TextBox.InputScope>

            </TextBox>

            <!--后台将此 TextBox 的 InputScope 设置为“EmailUserName”-->

            <!--SIP 包括 @ 和 .com 键，按住 .com 键可以显示“.org .com .edu .net”-->

            <TextBox Name="textBox" KeyDown="textBox_KeyDown" />

        </StackPanel>

    </Grid>

</phone:PhoneApplicationPage>
