PieChart图形绘制方法中，调用MathHelper的calcArcEndPointXY方法进行角度计算。 在计算过程中将角度转换为弧度，再判断不同象限进行计算，最后得到点的坐标。这里是否可以直接使用角度公式 mPosX = (float) (radius * Math.cos(cirAngle * Math.PI / 180)); mPosY = (float) (radius * Math.sin(cirAngle * Math.PI / 180)); mPointF.x = mPosX; mPointF.y = mPosY; 这样处理可以不进行角度转弧度，也不需要区分象限
mPosX = (float) (radius * Math.cos(cirAngle * Math.PI / 180));
mPosY = (float) (radius * Math.sin(cirAngle * Math.PI / 180));
mPointF.x = mPosX;
mPointF.y = mPosY;
