Re: [android-developers] Re: TextView with a top margin that is proportional to the height of the parent view
John, You can do this with LinearLayout and layout_weight attribute that it supports: LinearLayout layout_height=fill_parent orientation=vertical View layout_height=0dp layout_weight=20/ TextView layout_height=0dp layout_weight=80/ /LinearLayout The top view acts as a spacer, taking up 20% of the screen height, and the TextView starts below that. -- Kostya 29.01.2011 10:59, Jonathan Foley пишет: Yes, but you'll have to do it at runtime as there is not a way to do proportional layout as you describe in xml. To prevent a visible transition from the xml size to the correct size, you'll probably want to extend LinearLayout and override its onLayout(). You'll want to layout your child textview within that and you'll want to use getHeight() to get the height of the LinearLayout at runtime.

You can override onFinishInflate of the LinearLayout and then adjust the height of the TextView from there. You'll need to invalidate the TextView after adjusting it's height.

That works great. Thanks!
