Hi Dan, My workaround is to simply not allow more than one note - bad for my application :( (ExpandableListView is not appropriate). But this way, I can specify a fixed value layout_height="50dip". IMHO it is a bug.
I opened a bug on this: http://code.google.com/p/android/issues/detail?id=512 "when I try the workaround of having a dummy note - so that at least one note is always present - it still gives an unspecified size error. Logically, this should have worked, right? I could be mistaken, but it seems the real problem is the inner ListView is not recalculating its size. It is not expanding when it grows. It seems to be taking the values specified in the layout file, and not the current dynamic state at runtime." thanks, Anil On Mar 23, 3:09 pm, "Dan U." <[EMAIL PROTECTED]> wrote: > I'm going to suggest that it won't work.
