Is there an easy way to add a border to the top and bottom of an Android View?

In android 2.2 you could do the following.

Create an xml drawable such as /res/drawable/textlines.xml and assign this as a TextView's background property.

<TextView
android:text="My text with lines above and below"
android:background="@drawable/textlines"
/>

/res/drawable/textlines.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item>
      <shape 
        android:shape="rectangle">
            <stroke android:width="1dp" android:color="#FF000000" />
            <solid android:color="#FFDDDDDD" />

        </shape>
   </item>

   <item android:top="1dp" android:bottom="1dp"> 
      <shape 
        android:shape="rectangle">
            <stroke android:width="1dp" android:color="#FFDDDDDD" />
            <solid android:color="#00000000" />
        </shape>
   </item>

</layer-list>

The down side to this is that you have to specify an opaque background colour, as transparencies won't work. (At least i thought they did but i was mistaken). In the above example you can see that the solid colour of the first shape #FFdddddd is copied in the 2nd shapes stroke colour.

I've used a trick so that the border is displayed outside the container. With this trick only a line is drawn so the background will be shown of the underlying view.

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item
        android:bottom="1dp"
        android:left="-2dp"
        android:right="-2dp"
        android:top="-2dp">
        <shape android:shape="rectangle" >
            <stroke
                android:width="1dp"
                android:color="#FF000000" />

            <solid android:color="#00FFFFFF" />

            <padding android:left="10dp"
                android:right="10dp"
                android:top="10dp"
                android:bottom="10dp" />
        </shape>
    </item>

</layer-list>
