我想畫在畫布上的橢圓形。基本上,我將四條貝塞爾曲線組合成橢圓形。如何關閉畫布中複雜的路徑?
我成功繪製了一個橢圓形,但我不知道如何關閉它。
代碼:
//Paints for bazier curve
Paint bezierPaint = new Paint();
bezierPaint.setColor(Color.RED);
bezierPaint.setStyle(Paint.Style.STROKE);
bezierPaint.setStrokeCap(Paint.Cap.ROUND);
bezierPaint.setStrokeWidth(3.0f);
bezierPaint.setAntiAlias(true);
//Oval Path
Path ovalPath = new Path();
//Draw the first curve. from top point to right point
ovalPath.moveTo(160,0);
ovalPath.cubicTo(210, 0, 260, 100, 260, 150);
//Draw the second curve. from right point to bottom point
ovalPath.moveTo(260, 150);
ovalPath.cubicTo(260, 200, 210, 300, 160, 300);
//Draw the thrid curve. from bottom point to left point
ovalPath.moveTo(160, 300);
ovalPath.cubicTo(110, 300, 60, 200, 60, 150);
//Draw the fourth curve. from left point to top point
ovalPath.moveTo(60, 150);
ovalPath.cubicTo(60, 100, 110, 0, 160, 0);
**//I expect this oval close correctly. But in actually, the fourth curve was closed.
//Please see the image in attachment.How should I close this path as my expectation?**
ovalPath.close()
canvas.drawPath(ovalPath, bezierPaint);
爲什麼你沒有使用Shape(http://developer.android.com/reference/android/graphics/drawable/shapes/OvalShape.html)和resize(x,y)(http://developer.android.com /reference/android/graphics/drawable/shapes/Shape.html#resize(float,float)) – Mario
