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>
