I have some problems with textbox on webview at android 2.2 .
When I click on a textbox on my app the keyboard open but textbox move outside of top of page and when I click on keys that page jump up and down!
on another sample project textbox don't move to top of keyboard and stay at behind of keyboard.
also I used windowSoftInputMode: Titanium.UI.Android.SOFT_INPUT_ADJUST_UNSPECIFIED and windowSoftInputMode: Titanium.UI.Android.SOFT_INPUT_ADJUST_RESIZE
when creating window but they didn't resolve my problems.
You probably need to use PAN. Also, you didn't say which mobilesdk you're using.
