很酷炫时钟
自己没有艺术细胞UI设计就免了稍微介绍下实现背景换成比较炫图片就可以成为比较炫时钟了实现原理是根据时间计算角度
再计算时钟指针终点
代码比较简单:
XAML:
<Canvas>
<Ellipse Stroke="Transparent" Width="120" Height="120">
<Ellipse.Fill>
<RadialGradientBrush>
<GradientStop Color="White" Off
="0"></GradientStop>
<GradientStop Color="#DBDDE6" Off="0.7"></GradientStop>
<GradientStop Color="#ACABC4" Off="1"></GradientStop>
</RadialGradientBrush>
</Ellipse.Fill>
</Ellipse>
<Line x:Name="lnHor" Stroke="Red" StrokeThickness="3" X1="60" Y1="60" X2="60" Y2="60"></Line>
<Line x:Name="lnMin" Stroke="Yellow" StrokeThickness="2" X1="60" Y1="60" X2="60" Y2="60"></Line>
<Line x:Name="lnSec" Stroke="Blue" StrokeThickness="2" X1="60" Y1="60" X2="60" Y2="60"></Line>
<Ellipse Stroke="White" Width="6" Height="6" Fill="Black" Canvas.Left="57" Canvas.Top="57">
</Ellipse>
</Canvas>C#:
DispatcherTimer timer;
const 
secLen = 50;
const minLen = 43;
const horLen = 35;
DateTime dt;
sec;
min;
hor;
double angle;
public Page
{
InitializeComponent;
timer = 
DispatcherTimer;
timer.Interval = TimeSpan(0, 0, 1);
timer.Start;
timer.Tick 
EventHandler(timer_Tick);
}
void timer_Tick(object sender, EventArgs e)
{
dt = DateTime.Now;
sec = dt.Second;
min = dt.Minute;
hor = dt.Hour;
angle = Math.PI / 30 * sec - Math.PI / 2;
lnSec.X2 = 60 + Math.Cos(angle) * secLen;
lnSec.Y2 = 60 + Math.Sin(angle) * secLen;
angle = Math.PI / 1800 * (min * 60 + sec) - Math.PI / 2;
lnMin.X2 = 60 + Math.Cos(angle) * minLen;
lnMin.Y2 = 60 + Math.Sin(angle) * minLen;
angle = Math.PI / 21600 * (hor * 3600 + min * 60 + sec) - Math.PI / 2;
lnHor.X2 = 60 + Math.Cos(angle) * horLen;
lnHor.Y2 = 60 + Math.Sin(angle) * horLen;
}代码比较简单
不多解释运行效果:
