`drawCircle()` 半径参数单位？
`drawCircle()` radius parameters units?
Canvas.drawCircle()方法中半径参数的单位是什么？
是像素吗？还是下降？
http://developer.android.com/reference/android/graphics/Canvas.html#drawCircle(float, 浮动, 浮动, android.graphics.Paint)
我试图查看源代码以查看是否能得到任何想法，但该方法只是一个包装器，文档没有指定任何内容。
据official docs报道：
When you're writing an application in which you would like to perform specialized drawing and/or control the animation of graphics, you should do so by drawing through a Canvas. A Canvas works for you as a pretense, or interface, to the actual surface upon which your graphics will be drawn — it holds all of your "draw" calls. Via the Canvas, your drawing is actually performed upon an underlying Bitmap, which is placed into the window.
根据定义，位图使用 像素 ，而不是其他任何单位。
因此，所有drawXYZ()方法都在px.
