I want to make a UI
element like a GridView
, I want it's complete functionality but want it to be horizontally scrollable rather than vertically.
By horizontal scroll I mean it should be built that way and not put in a HorizontalScrollView
.
My would be Custom GridView
will have fixed number of rows
say 4-5
and the columns
should be extensible
based on number of items in the Adapter
. You can think of it as the opposite of what the native GridView
does, yet it should maintain the functionality.
I have looked at the source code of how a GridView
is implemented by Google, but I am able to understand very less and starting to make the View
from scratch doesn't seem to be a good idea, since I am afraid I will not be able to do justice to memory optimization's the way Google did it.
I had observed that GridView
extends AbsListView
, so my question is, is it AbsListView
which lets a GridView
scroll vertically and add items from the adapter, or is it GridView
which adds the vertical scrolling ability? Should I tweak GridView
or AbsListView
?
It would be even better to know if there's something which already does what I want to do?
This has already been implemented in native Gallery and YouTube app of Android Honeycomb 3.1 and above. So if anyone has an idea, please elaborate.
