recyclerview 的背景是一个简单的图像,应该通过线性布局显示.但不幸的是,结果是这样的:
The Background of the recyclerview is a simple image, that is supposed to show through the linear layouts. But unfortunately, this is the result:
所以,如您所见,背景显示恰到好处,但我在这里使用的卡片视图的透明布局是一些有线黑色.
So, as you can see, the background is displayed just right but the supposed to be transparent layout for the cardview i am using here is some wired black.
我可以制作任何我想要的颜色,但是:
I can make it whatever color I want, but with:
android:background="@android:color/transparent"
它只是变黑了.
有人可以帮我吗?
谢谢!:)
推荐答案
... 原来 CARDVIEWS 没有这样的属性.使 rootlayout 成为线性布局解决了这个问题.
... turns out CARDVIEWS do not have such attribute. Making the rootlayout a linearlayout solved this issue.
