如何在Android xml可繪製文件中定義圓形？ - How to define a circle shape in an Android xml drawable file?

問題：

I have some problems finding the documentation of the definitions of shapes in XML for Android. 我在查找Android版XML中的形狀定義文檔時遇到一些問題。 I would like to define a simple circle filled with a solid color in an XML File to include it into my layout files. 我想在XML文件中定義一個用純色填充的簡單圓圈，以將其包含到佈局文件中。

Sadly the Documentation on android.com does not cover the XML attributes of the Shape classes. 遺憾的是，android.com上的文檔未涵蓋Shape類的XML屬性。 I think I should use an ArcShape to draw a circle but there is no explanation on how to set the size, the color, or the angle needed to make a circle out of an Arc. 我想我應該使用ArcShape畫一個圓，可是沒有設置如何設置從圓弧中畫出圓所需的大小，顏色或角度的說明。
