关于布局：如何在Android中用分区绘制圆？


How to draw circle with partitioned in android?

我想在我的应用程序中绘制这种类型的圆。我可以使用Canvas画圆，但是我对如何进行分区一无所知？

有人可以建议我如何分割圆吗？

预先感谢。

这是您需要的工作代码。...

我有一个主意，首先使用

在带有分区的圆内绘制

1
        can.drawArc(oval, startAngle, sweepAngle, useCenter, paint)

将angular值取为0 t0 60，然后再次绘制另一个具有相同中心的圆弧，取angular值为60至120，依此类推。每次在Paint中设置不同的颜色。完成内圆之后，几乎完成了所有工作。现在在第一个圆之后画一个具有相同中心但半径较小的白色圆，这样它将在第一个

上创建

希望它会对您有所帮助：)
