[android-developers] Re: Child TextView in ScrollView with large amount of text pushes other views off the screen
It does matter, 0dip is an optimization. If you use something > 0 then that space will be taken away from other widgets. In this case there's no reason not to use 0dip.

[android-developers] Re: Child TextView in ScrollView with large amount of text pushes other views off the screen
This words, thanks. However, it appears to me the value you specify for the height is an arbitrary one. For example, it doesn't seem to matter if specify 1dip or 100dip, it still sizes the same. I assume what's going on is that the layout_weight="1.0" tells the layout manager to give as much real estate as possible to the ScrollView and as little possible to it's sibling Views and you just need to specify SOMETHING for the height.

[android-developers] Re: Child TextView in ScrollView with large amount of text pushes other views off the screen
You set the scrollview to have a height of wrap_content, which means "be as big as you need to be to show your children." What you want instead is a height of 1.0 and android:layout_weight="1.0" On Wed, May 6, 2009 at 4:02 PM, Mike wrote: > > OK, I give up.
