网上找了 好久 没找到好的
自己实现了3种
1.用clip属性
2。用装饰器Adorner
3.修改模板
1。clip 就是画一个圆角矩形
但是这个在listview size 变化时 也要调用这个方法
代码如下：
1 using System; 2 using System.Windows; 3 using System.Windows.Media; 4 5 class ClipRadiusView 6 { 7 private static double DisX = 20; 8 private static double DisY = 20; 9 static Size XY=new Size(DisX,DisY); 10 11 private static bool isLarge = false; 12 private static bool isStroke = true; 13 private static double angle = 150; 14 15 private static int offx = 3; 16 private static int offy = 2; 17 18 static Point StartPoint = new Point(offx, DisY); 19 static Point P1 = new Point(DisX, offy); 20 21 22 public static void InitClip(FrameworkElement el) 23 { 24 double w = el.ActualWidth; 25 double h = el.ActualHeight; 26 if(w<DisX*2||h<DisY*2) 27 return; 28 29 30 PathFigure myFigure=new PathFigure(); 31 32 33 34 myFigure.StartPoint = StartPoint; 35 36 ArcSegment a1=new ArcSegment(P1, XY, angle,isLarge,SweepDirection.Clockwise, isStroke); 37 myFigure.Segments.Add(a1); 38 39 Point p2 = new Point(w - DisX, offy); 40 LineSegment l1 = new LineSegment(p2, true); 41 myFigure.Segments.Add(l1); 42 43 Point p3 = new Point(w, DisY); 44 ArcSegment a2 = new ArcSegment(p3, XY, angle, isLarge, SweepDirection.Clockwise, isStroke); 45 myFigure.Segments.Add(a2); 46 47 Point p4 = new Point(w, h - DisY); 48 LineSegment l2 = new LineSegment(p4, true); 49 myFigure.Segments.Add(l2); 50 51 Point p5 = new Point(w - DisX, h); 52 ArcSegment a3 = new ArcSegment(p5, XY, angle, isLarge, SweepDirection.Clockwise, isStroke); 53 myFigure.Segments.Add(a3); 54 55 Point p6 = new Point(DisX, h); 56 LineSegment l3 = new LineSegment(p6, true); 57 myFigure.Segments.Add(l3); 58 59 Point p7 = new Point(offx, h - DisY); 60 ArcSegment a4 = new ArcSegment(p7, XY, angle, isLarge, SweepDirection.Clockwise, isStroke); 61 myFigure.Segments.Add(a4); 62 63 //Point p8 = new Point(offx, DisY); 64 //LineSegment l4 = new LineSegment(p8, true); 65 //myFigure.Segments.Add(l4); 66 67 myFigure.IsClosed = true; 68 PathGeometry pg = new PathGeometry(); 69 pg.Figures.Add(myFigure); 70 el.ClipToBounds = true; 71 el.Clip = pg; 72 } 73 }
2.装饰器Adorner
就是再四个角落画一个和背景色一样的圆角
这个 会随着尺寸变化而变化
using System.Windows;
using System.Windows.Documents;
using System.Windows.Media;
class RadiusAdorner : Adorner
{
private Brush _backBrush = Brushes.White;
private Pen renderPen;
public RadiusAdorner(UIElement el, Brush pen)
: base(el)
{
if (pen != null)
_backBrush = pen;
renderPen = new Pen(_backBrush, 0);
}
private static double DisX = 20;
private static double DisY = 20;
Size XY = new Size(DisX, DisY);
private bool isLarge = false;
private bool isStroke = true;
private double angle = 90;
private double penSize = 2;
private Point _start;
private PathGeometry _pg;
private PathFigure _pf;
private Point _start1;
private Point _p1;
private Point _p2;
private LineSegment _line;
private ArcSegment _arc;
private Rect _adornedElementRect;
protected override void OnRender(DrawingContext drawingContext)
{
_adornedElementRect = new Rect(this.AdornedElement.RenderSize);
double w = _adornedElementRect.Width;
double h = _adornedElementRect.Height;
_start = new Point(_adornedElementRect.X, _adornedElementRect.Y);
_pg = new PathGeometry();
_pf = new PathFigure();
//左上角
_start1 = _start;
_pf = new PathFigure();
_pf.StartPoint = _start1;
_p1 = new Point(_start1.X + DisX, _start1.Y);
_line = new LineSegment(_p1, true);
_pf.Segments.Add(_line);
_p2 = new Point(_start1.X, _start1.Y + DisY);
_arc = new ArcSegment(_p2, XY, angle, isLarge, SweepDirection.Counterclockwise, isStroke);
_pf.Segments.Add(_arc);
_pf.IsClosed = true;
_pg.Figures.Add(_pf);
////顶部画一条线
//_start1 = new Point(_start.X, _start.Y + 2); ;
//_pf=new PathFigure();
//_pf.StartPoint = _start1;
//_p1=new Point(_start1.X+w,_start1.Y);
//_line=new LineSegment(_p1,true);
//_pf.Segments.Add(_line);
//_pg.Figures.Add(_pf);
//右上角
_start1 = new Point(_start.X + w, _start.Y);
_pf = new PathFigure();
_pf.StartPoint = _start1;
_p1 = new Point(_start1.X - DisX, _start1.Y);
_line = new LineSegment(_p1, true);
_pf.Segments.Add(_line);
_p2 = new Point(_start1.X, _start1.Y + DisY);
_arc = new ArcSegment(_p2, XY, angle, isLarge, SweepDirection.Clockwise, isStroke);
_pf.Segments.Add(_arc);
_pf.IsClosed = true;
_pg.Figures.Add(_pf);
//右下角
_start1 = new Point(_start.X + w, _start.Y + h);
_pf = new PathFigure();
_pf.StartPoint = _start1;
_p1 = new Point(_start1.X - DisX, _start1.Y);
_line = new LineSegment(_p1, true);
_pf.Segments.Add(_line);
_p2 = new Point(_start1.X, _start1.Y - DisY);
_arc = new ArcSegment(_p2, XY, angle, isLarge, SweepDirection.Counterclockwise, isStroke);
_pf.Segments.Add(_arc);
_pf.IsClosed = true;
_pg.Figures.Add(_pf);
//左下角
_start1 = new Point(_start.X, _start.Y + h);
_pf = new PathFigure();
_pf.StartPoint = _start1;
_p1 = new Point(_start1.X + DisX, _start1.Y);
_line = new LineSegment(_p1, true);
_pf.Segments.Add(_line);
_p2 = new Point(_start1.X, _start1.Y - DisY);
_arc = new ArcSegment(_p2, XY, angle, isLarge, SweepDirection.Clockwise, isStroke);
_pf.Segments.Add(_arc);
_pf.IsClosed = true;
_pg.Figures.Add(_pf);
drawingContext.DrawGeometry(renderPen.Brush, renderPen, _pg);
}
static Brush defaulBrushe=new SolidColorBrush(new Color{A = 255,R=137,G=181,B=233});
public static void AddRadiusAdorner(FrameworkElement el)
{
RadiusAdorner ra=new RadiusAdorner(el,defaulBrushe);
AdornerLayer al = AdornerLayer.GetAdornerLayer(el);
if (al != null)
{
al.Add(ra);
}
}
}
3 模板
就是修改ListView的默认Template 参考msdn listview样式里的 改
但是gridview的上面部分 不能切成圆角
