cornerradius如何给TextView加个圆角？

刀具几何角度，中英文对照

CUTTING EDGE RADIUS和SIDE EDGE RADIUS应该是主切削刃和副切削刃圆角的意思，表征切削刃的锋利程度，而CONNER RADIUS应该是刀尖圆弧半径。

UG后处理输出底部圆角，进行判断，，有就输出，，无则显示“无”？？

回复 1# 报什么错。

我需要看到日志文件。

还有你这样的判断容易出现问题。

应该用info exists

C#窗体如何给所有的边框加上阴影

我使用的方法是绘制阴影到bitmap上，然后使用双层窗体的原理把bitmap绘制到背景层上去。

其中比较重要的是： 1、绘制圆角矩形 public static void DrawRoundRectangle(Graphics g, Pen pen, Rectangle rect, int cornerRadius) { using (GraphicsPath path = CreateRoundedRectanglePath(rect, cornerRadius)) { g.DrawPath(pen, path); } } public static void FillRoundRectangle(Graphics g, Brush brush, Rectangle rect, int cornerRadius) { using (GraphicsPath path = CreateRoundedRectanglePath(rect, cornerRadius)) { g.FillPath(brush, path); } } internal static GraphicsPath CreateRoundedRectanglePath(Rectangle rect, int cornerRadius) { GraphicsPath roundedRect = new GraphicsPath(); roundedRect.AddArc(rect.X, rect.Y, cornerRadius * 2, cornerRadius * 2, 180, 90); roundedRect.AddLine(rect.X + cornerRadius, rect.Y, rect.Right - cornerRadius * 2, rect.Y); roundedRect.AddArc(rect.X + rect.Width - cornerRadius * 2, rect.Y, cornerRadius * 2, cornerRadius * 2, 270, 90); roundedRect.AddLine(rect.Right, rect.Y + cornerRadius * 2, rect.Right, rect.Y + rect.Height - cornerRadius * 2); roundedRect.AddArc(rect.X + rect.Width - cornerRadius * 2, rect.Y + rect.Height - cornerRadius * 2, cornerRadius * 2, cornerRadius * 2, 0, 90); roundedRect.AddLine(rect.Right - cornerRadius * 2, rect.Bottom, rect.X + cornerRadius * 2, rect.Bottom); roundedRect.AddArc(rect.X, rect.Bottom - cornerRadius * 2, cornerRadius * 2, cornerRadius * 2, 90, 90); roundedRect.AddLine(rect.X, rect.Bottom - cornerRadius * 2, rect.X, rect.Y + cornerRadius * 2); roundedRect.CloseFigure(); return roundedRect;} 2、绘制阴影 internal void DrawShadow() { Bitmap bitmap = null; Graphics g = null; ? ?try { bitmap = new Bitmap(Width, Height); g = Graphics.FromImage(bitmap); g.SmoothingMode = SmoothingMode.AntiAlias; Color c = Color.FromArgb(0, 0, 0, 0); Pen p = new Pen(c, 3); ? ? ? ?for (int i = 0; i < Main.ShadowWidth; i++) { p.Color = Color.FromArgb((255 / 10 / Main.ShadowWidth) * i, c); DrawRoundRectangle(g, p, new Rectangle(i, i, Width - (2 * i) - 1, Height - (2 * i) - 1), Main.ShadowWidth - i); } SetBits(bitmap); } ? ?catch { } ? ?finally { g?.Dispose(); bitmap?.Dispose(); } } 3、绘制半透明bitmap到窗口上 protected override CreateParams CreateParams { get { CreateParams cParms = base.CreateParams; cParms.ExStyle |= 0x00080000; // WS_EX_LAYERED return cParms; } } public void SetBits(Bitmap bitmap) { if (!Image.IsCanonicalPixelFormat(bitmap.PixelFormat) || !Image.IsAlphaPixelFormat(bitmap.PixelFormat)) throw new ApplicationException("图片必须是32位带Alhpa通道的图片。

"); IntPtr oldBits = IntPtr.Zero; IntPtr screenDC = FormStyleAPI.GetDC(IntPtr.Zero); IntPtr hBitmap = IntPtr.Zero; IntPtr memDc = FormStyleAPI.CreateCompatibleDC(screenDC); try { Loc = new FormStyleAPI.Point(Left, Top); FormStyleAPI.Size bitMapSize = new FormStyleAPI.Size(Width, Height); FormStyleAPI.BLENDFUNCTION blendFunc = new FormStyleAPI.BLENDFUNCTION(); FormStyleAPI.Point srcLoc = new FormStyleAPI.Point(0, 0); hBitmap = bitmap.GetHbitmap(Color.FromArgb(0)); oldBits = FormStyleAPI.SelectObject(memDc, hBitmap); blendFunc.BlendOp = FormStyleAPI.AC_SRC_OVER; blendFunc.SourceConstantAlpha = Byte.Parse(((int)(Main.Opacity * 255)).ToString()); blendFunc.AlphaFormat = FormStyleAPI.AC_SRC_ALPHA; blendFunc.BlendFlags = 0; FormStyleAPI.UpdateLayeredWindow(Handle, screenDC, Loc, ref bitMapSize, memDc, ref srcLoc, 0, ref blendFunc, FormStyleAPI.ULW_ALPHA); } finally { if (hBitmap != IntPtr.Zero) { FormStyleAPI.SelectObject(memDc, oldBits); FormStyleAPI.DeleteObject(hBitmap); } FormStyleAPI.ReleaseDC(IntPtr.Zero, screenDC); FormStyleAPI.DeleteDC(memDc); } } 四、最终方案的效果和源码

如何给TextView加个圆角？

要先加QuartzCore.framework，并且#import 顺便放上加边框的代码：transTextView.layer.borderWidth = 2.0f;transTextView.layer.borderColor = [[UIColor blackColor] CGColor];
