Create an XML file named border.xml in the drawable folder and put the following code in it.
在 drawable 文件夹中创建一个名为 border.xml 的 XML 文件，并将以下代码放入其中。
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<solid android:color="#FF0000" />
</shape>
</item>
<item android:left="5dp" android:right="5dp" android:top="5dp" >
<shape android:shape="rectangle">
<solid android:color="#000000" />
</shape>
</item>
</layer-list>
Then add a background to your linear layout like this:
然后为您的线性布局添加背景，如下所示：
android:background="@drawable/border"

It can also be done using a stroke to keep the background as transparent while still keeping a border except at the bottom with the following code.
也可以使用描边来完成，以保持背景透明，同时仍然保留边框，除了在底部使用以下代码。
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:left="0dp" android:right="0dp" android:top="0dp"
android:bottom="-10dp">
<shape android:shape="rectangle">
<stroke android:width="10dp" android:color="#B22222" />
</shape>
</item>
</layer-list>

肯尼是对的，只是想澄清一些事情。

- 创建文件
border.xml并将其放入文件夹res/drawable/ 添加代码
<shape xmlns:android="http://schemas.android.com/apk/res/android"> <stroke android:width="4dp" android:color="#FF00FF00" /> <solid android:color="#ffffff" /> <padding android:left="7dp" android:top="7dp" android:right="7dp" android:bottom="0dp" /> <corners android:radius="4dp" /> </shape>像

Mine first didn't work cause i put the border.xmlin the wrong folder!

Here is a Github linkto a lightweight and very easy to integrate library that enables you to play with borders as you want for any widget you want, simply based on a FrameLayout widget.
这是一个指向轻量级且非常易于集成的库的Github 链接，它使您可以根据需要为任何您想要的小部件使用边框，只需基于 FrameLayout 小部件。
Here is a quick sample code for you to see how easy it is, but you will find more information on the link.
这是一个快速示例代码，您可以看到它有多简单，但您可以在链接上找到更多信息。
<com.khandelwal.library.view.BorderFrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:leftBorderColor="#00F0F0"
app:leftBorderWidth="10dp"
app:topBorderColor="#F0F000"
app:topBorderWidth="15dp"
app:rightBorderColor="#F000F0"
app:rightBorderWidth="20dp"
app:bottomBorderColor="#000000"
app:bottomBorderWidth="25dp" >
</com.khandelwal.library.view.BorderFrameLayout>
So, if you don't want borders on bottom, delete the two lines about bottom in this custom widget, and that's done.
因此，如果您不希望底部有边框，请删除此自定义小部件中关于底部的两行，然后就完成了。
And no, I'm neither the author of this library nor one of his friend ;-)
不，我既不是这个图书馆的作者，也不是他的朋友之一 ;-)
