I would like to imitate the behavior of the default android browser – The EditText (the address bar) on top will start to “disappear” once the user scrolls down. The only thing I can think of right now is to put the EditText and the WebView in a ScrollView but that would create other problems, and is not recommended.
What do you think?
Create a custom View by extending WebView and override onScrollChanged(). With a little calculations you can accomplish your task.
