This document discusses cross-platform design between Windows Mobile 6.5 and Android 2.1. It describes using absolute layouts for Windows Mobile, but flow containers that dynamically arrange controls for Android. Designers can link platforms so that adding controls to one automatically adds it to the other, or unlink them when layouts diverge. The primary platform must be Windows Mobile if designing for both currently.

1. Cross Platform Design
● Windows Mobile 6.5
● Android 2.1 +
● Two Form Designs
● One set of
● Functions
● Menus
● Data structures

2. Layout in WM
● Absolute Layouts
● At present screen
assumed to be
240x320
● Auto scaling for
same aspect ratio

3. Layout in Android
● Flow Containers
● Add controls to flow container not directly to
Form
● Multiple controls in a flow layout, arranged
horizontally
Flow container markers

4. Layout in Android
● Flow containers can be dragged about
● Layout width – space divided between
controls
● Layout height – default
● But image-items a special case
● Image height determines control height

5. Layout in Android
● Outline View is useful

6. Linked Screen Designs
For any form
● Android design can be linked to Windows Design
or not
● If linked, then when you add a control to WM
designer it automatically gets added to Android
design
● A sensible default layout is attempted by Meme
IDE
● Unlink a form when the design diverges

7. Unlinking a Design

8. Primary Platform
● Linked screen
designs
● At present, if
designing for
Android and
WM, then WM
MUST be
primary

9. Re-linking
● If you re-link after making unlinked changes
● Those changes vanish
● They will reappear if you unlink again straight
away

10. Summary
● Two platforms
● WM – absolute layout
● Android – layout containers
● Linked or unlinked designs
