dojox.mobile.ScrollableView keyboard issue on Android

[Eric Wang]

On Android, when keyboard popup and directly transition to another view, the ScrollableView layout will failed. dojox.mobile.View works well. The layout failed including:

1. ScrollableView height calculate wrong
2. slide up/down cannot to the top or bottom
3. fixed header/footer disappear
4. when used in dojox.app, the transition failed (see todoApp)

See the attachment and the test case file. (put the test file in dojox/mobile/tests folder)

#15395 is a duplicate of this ticket.

4th point might be the same as #15386

[Eric Durocher]

Yes I see what causes the first 3 points, but the 4th seems different. EricWang, can you explain how to reproduce the 4th point in the todoApp please? Which version, exact steps, etc. Thanks!

Detect virtual keyboard show/hide on Android and update layout - Eric Durocher (IBM, CCLA)

Attaching a patch that seems to fix the first 3 points. The idea is to watch resize events caused by keyboard showing/hiding (we use a heuristic to detect this: width not changing + height changing by more than 100px, seems to work OK on all tested devices). EricWang if you can check that it works for you, thanks.

edurocher, it looks like you came up with a safer, less side-effect solution, though I'm not sure if the detection logic is always reliable. One concern is that some of the devices fire excessive number of onresize events, which could affect the performance. Anyway, that looks much better than simply changing onorientationchange to onresize. Good work. :)

[Eric Durocher]

Thanks for the feedback, the detection seems reliable on all tested Android devices. As for performance, in most cases the resize handler will just fetch the screen size (innerWidth/Height usually) and compare with the previous size, this should be really quick.
