如何将阴影设置为Android的视图?

在我的Android应用程序中，我需要一个带有圆角的布局，背景应该具有一定的透明度.为此，我正在使用此XML，它可以正常工作:

CustomShape.xml:

<shape android:shape="rectangle"> 
    <gradient android:startColor="#E2FFFFFF" android:endColor="#E2D0E3E5" android:angle="270"/> 
    <corners android:radius="10dp" /> 
</shape>

style.xml:

<style name="LinearLayoutRoundCorners">
    <item name="android:layout_width">fill_parent</item>
    <item name="android:layout_height">wrap_content</item>
    <item name="android:background">@drawable/customshape</item>
</style>

我还需要在布局的右侧和底部一个小阴影.我找不到这样做的方法.我已经看到了一个黑客，您将另一个布局放在后面，使其看起来像阴影，但这对我来说是不起作用的，因为我的布局具有透明度，因此看起来不太好.我如何在不使用图像作为布局的背景的情况下在布局上获得漂亮的阴影?

据我所知，

how to set shadow to a View in android?

In my Android app I need a layout with round corners and the background should have some transparency. For this I'm using this xml, it works fine:

customshape.xml:

<shape android:shape="rectangle"> 
    <gradient android:startColor="#E2FFFFFF" android:endColor="#E2D0E3E5" android:angle="270"/> 
    <corners android:radius="10dp" /> 
</shape>

style.xml:

<style name="LinearLayoutRoundCorners">
    <item name="android:layout_width">fill_parent</item>
    <item name="android:layout_height">wrap_content</item>
    <item name="android:background">@drawable/customshape</item>
</style>

I also need a small shadow to the right and bottom of the layout. I can not find a way to do this. I've seen a hack where you put another layout behind to make it look like a shadow but that will not work for me as my layout have transparency, so that will not look very good. How can I get a nice looking shadow on my layout without using an image as background of the layout?

I know this is way late, but I was reading this question/answer combo and though of an alternative method that doesn't require an image. I threw together a post on my blog explaining. I figure it would be helpful to future visitors to have both of these answers handy here.
