You cannot do that using Java Code.

For alls who are stuck at this problem, I have some conclusion about scrolling a webview in android.

• You cannot scroll a webview or get scrolling position using Java Code.
• You can only get layoutHeight, measuredHeight, contentHeight of a webview, nothing more. These are all the android api allowing you do in getting and setting scroll status.
• But, you can override the onScorllChanged to add a self-define listener for scrolling webview event(or fling event), you will be notified the origin position and the new position.
• Well, you can scroll to a position using JavaScript code, like the following, but the performance is really poor. If you want to scroll it frequently, please give it a second thought.

  window.scrollTo(100,500)

Consider your situation and choose a proper solution. Also be noticed that fling and scroll are different things.
