Setting View's Width & Height to -1

[DerekTweed]

In the code for an example widget that I have downloaded, an Imageview has Width & Height set to -1. What effect does this have?
I have searched for a reference to this, but cannot find one.

Thanks

Special value for the height or width requested by a View. MATCH_PARENT means that the view wants to be as big as its parent, minus the parent's padding, if any. Introduced in API Level 8.

Constant Value: -1 (0xffffffff)
