Windows Phone 8.1 Path按钮制作分享
前言
经常在博客园看大家的文章,由于本人文笔太烂,没写过博客和小伙伴们分享过,昨天看到安卓同事做的那个按钮比较不错,就想着也做个。现在把过程写出来,请大家不吝赐教(第一次发博客不会排版。。。)大家凑合看吧
开始
一般要做动画之前,习惯用blend先做个动画,因为blend做动画很快,可以方便的看到动画的效果,待动画调试差不多的时,用vs打开 (一个展开的动画和一个收回的动画,其实设置下Storyboard的AutoReverse属性可以自动执行收回的动画但是过程没办法控制,只能写两个动画分开)
根据需求,如有动画比较灵活,那就要把生成的xaml代码转化为C#代码了。(用blend的好处就是调试动画很方便转化为C#代码的时候也比较很简单),其中用到了四个动画X轴的平移,Y轴的平移,中心点的旋转,属性值的改变。
代码用到了关键帧动画,所以看起来比较长,其实可以不用关键帧动画,直接DoubleAnimation就行
这个动画主要控制五个按钮的旋转,从-360到0之间的旋转动画
Storyboard expand = new Storyboard(); for (int i = 0; i < 5; i++) { //旋转动画 DoubleAnimationUsingKeyFrames rotation = new DoubleAnimationUsingKeyFrames(); Storyboard.SetTargetProperty(rotation, "(UIElement.RenderTransform).(CompositeTransform.Rotation)"); //只有动画在xaml中才可以使用这个方法 // Storyboard.SetTargetName(rotation, "image" + i); Storyboard.SetTarget(rotation, this.FindName("image"+i) as Image); EasingDoubleKeyFrame startAngle = new EasingDoubleKeyFrame(); startAngle.Value = -360; startAngle.KeyTime = KeyTime.FromTimeSpan(TimeSpan.FromMilliseconds(0)); rotation.KeyFrames.Add(startAngle); if (i==2) { rotation.BeginTime = TimeSpan.FromMilliseconds(50); } else if (i==3) { rotation.BeginTime = TimeSpan.FromMilliseconds(100); } else if (i==4) { rotation.BeginTime = TimeSpan.FromMilliseconds(150); } EasingDoubleKeyFrame endAngle = new EasingDoubleKeyFrame(); endAngle.Value = 0; endAngle.KeyTime = KeyTime.FromTimeSpan(TimeSpan.FromMilliseconds(500)); rotation.KeyFrames.Add(endAngle); expand.Children.Add(rotation); }
rotation.BeginTime = TimeSpan.FromMilliseconds(50);
这个是控制按钮出来时候的顺序,上面的按钮先执行动画。
Y轴平移的动画,每个按钮平移的距离不同所以只能用if else判断了。注意
//只有动画在xaml中才可以使用这个方法
// Storyboard.SetTargetName(rotation, "image" + i);
Storyboard.SetTarget(rotation, this.FindName("image"+i) as Image);//代码生成的动画用这个方法
for (int i = 1; i < 5; i++) { //Y轴平移 DoubleAnimationUsingKeyFrames ytransalte = new DoubleAnimationUsingKeyFrames(); Storyboard.SetTargetProperty(ytransalte, "(UIElement.RenderTransform).(CompositeTransform.TranslateY)"); Storyboard.SetTarget(ytransalte, this.FindName("image" + i) as Image); //起始点 EasingDoubleKeyFrame ystartPoint = new EasingDoubleKeyFrame(); ystartPoint.KeyTime = KeyTime.FromTimeSpan(TimeSpan.FromMilliseconds(0)); if (i == 1) { ystartPoint.Value = http://www.mamicode.com/180;>
X轴的动画大同小异,就不写了,下面是Image,是否显示属性值的改变(按钮还未出来的时候,是在页面隐藏的,收回按钮后,又隐藏)
//改变属性值的动画 ObjectAnimationUsingKeyFrames visi = new ObjectAnimationUsingKeyFrames(); Storyboard.SetTargetProperty(visi, "(UIElement.Visibility)"); Storyboard.SetTarget(visi, this.FindName("image" + i) as Image); DiscreteObjectKeyFrame startObj = new DiscreteObjectKeyFrame(); startObj.KeyTime = KeyTime.FromTimeSpan(TimeSpan.FromMilliseconds(0)); startObj.Value = http://www.mamicode.com/Visibility.Visible;>
上面是按钮展开的动画,还要写收回的动画,改下展开动画的代码就好了。
