Is there an easy way to do that scrolling where someone moves their finger really fast across the screen and the scrolling continues a bit after their finger has lifted? --

Yup - real easy - just put your finger down on a scrollable item on the screen and flick it really fast. It will do exactly what you describe. ------------------------------------------------------------------------------------------------- TreKing < http://sites.google.com/site/rezmobileapps/treking> ; - Chicago transit tracking app for Android-powered devices --
1. Should I use "synchronized" for a boolean variable
Hi,
I use a boolean variable "flag" both in main and child thread. This
"flag" is used to notify child thread to exit. I only use simple
operation, e.g., "flag=false", "if (flag) {}". As I know, in java,
"get and set a boolean variable" is atomic. So "synchronized" is not
needed for variable "flag", declaring "flag" as "volatile" is enough.
Is this still true in Android?
Thanks

Hello Friends,
I have a question about landscape view. In my application i have set
layout gravity property to bottom (android:gravity="bottom") and
another property marginTop="-37dip". I have a scrollView and few more
layouts. When i run application in normal view it works fine but when
i change screen view to landscape, half of layout at the bottom go
down from the screen. Any solution plz. Here is my layout code.
