[android-developers] obtaining true dimensions of a View larger than the screen

2011-05-05 Thread kellogs
Hello,

trying to implement a dynamic scrolview wrapping mechanism here. But
no matter what method I try from the View class they all return me the
view's part of height that is currently visible on screen. So if there
are 360 pixels available for a textview that has lots of text and is
currently using 400 pixels its getHeight() and many other related
methods always report 360.

Any way around this ? maybe getting to the View's Canvas ? How can I
go about that ?

Thank you!

The only thing View knows is these methods it calls on itself to have
subclasses tell it how to show the scroll bars:

http://developer.android.com/reference/android/view/View.html#computeHorizontalScrollExtent()

Beyond that, you will need to look at a specific class that is doing
scrolling.
