示例1: Draw
public void Draw(Canvas c, Rect bounds)
{
RectF arcBounds = mTempBounds;
arcBounds.Set(bounds);
arcBounds.Inset(mStrokeInset, mStrokeInset);
float startAngle = (mStartTrim + mRotation) * 360;
float endAngle = (mEndTrim + mRotation) * 360;
float sweepAngle = endAngle - startAngle;
mPaint.Color = mColors[mColorIndex];
c.DrawArc(arcBounds, startAngle, sweepAngle, false, mPaint);
DrawTriangle(c, startAngle, sweepAngle, bounds);
if (Alpha < 255)
{
mCirclePaint.Color = BackgrounColor;
mCirclePaint.Alpha = 255 - Alpha;
c.DrawCircle(bounds.ExactCenterX(), bounds.ExactCenterY(), bounds.Width() / 2, mCirclePaint);
}

private void DrawTriangle(Canvas c, float startAngle, float sweepAngle, Rect bounds)
{
if (mShowArrow)
{
if (mArrow == null)
{
mArrow = new Path();
mArrow.SetFillType(Path.FillType.EvenOdd);

}示例3: IsWithinCircularBounds
static bool IsWithinCircularBounds(Rect hit, Rect bounds)
{
if (!bounds.Contains(hit)) return false;
// Forumula for a circle: (x-a)2 + (y-b)2 = r2
var centerX = bounds.ExactCenterX() - bounds.Left;
var centerY = bounds.ExactCenterY() - bounds.Top;
var radius = centerX;
double x = hit.Left - bounds.Left,
y = hit.Top - bounds.Top,
r2 = radius * radius,
xx = (x - centerX);
var yy = Math.Sqrt(r2 - xx*xx) + 0.5;
var upperBound = centerY - yy;
var lowerBound = centerY + yy;
var result = !Double.IsNaN (y) && y > upperBound && y < lowerBound;
return result;
