我无法弄清楚为什么这段代码不起作用.有人可以帮忙吗?我试图让按钮使用名为'greenstart'和'greenend'的自定义颜色.颜色已在res/value/string.xml文件中创建.我已经查看了类似的问题,但要么他们没有得到答复,不清楚,要么解决方案不起作用.提前致谢.
XML文件示例:
<Button
android:id="@+id/mycollection"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:layout_weight="1" >
<Gradient
android:angle="270"
android:endColor="@color/greenstart"
android:startColor="@color/greenend" >
</Gradient>
</Button>

当我这样做时,我可以按F5来渲染仅包含不包含交集的STL文件.或者我可以点击F6进行编译和渲染,但它会创建一个非常混乱的渲染,没有接近多方面,甚至接近我对此事的预期.使用OpenSCAD是否有解决此问题的方法?谢谢!
