 From the reference page for <text>:

multiline
If true, the lines of text are wrapped to fit within the text width.  
(The name multiline is a misnomer. Unwrapped text can be multiple  
lines if it contains a <br /> or <p>  element, or a line break within  
a <pre> element. This attribute defaults to true if width and height  
are explicitly specified. If you set multiline=true, you probably  
want to explicitly a width for the text also; if multiline=true and  
you do not specify a width, the system will pick an arbitrary width  
(100 pixels at the moment). When multiline=true, the text is  
automatially re-wrapped whenever the content is modified by calls to  
setText, or whenever the width of the text view is modified.
