Scroll map inside scrollview automatically while scrolling scrollview

Issue

How to scroll map automatically which is inside scrollview like Expedia Application?

Solution

Got the solution. First create custom scrollview. Put mapview inside scrollview. Then on onScrollChanged of custom scrollview, scroll the mapview like,

On CustomScrollView.java:

protected void onScrollChanged(int l, int t, int oldl, int oldt) 
{
    super.onScrollChanged(l, t, oldl, oldt);
    scrollMap(l,t);
}

On YourActivity.java:

public void scrollMap(int x, int y)
{
    int scrollLength = scrollView.getMeasuredHeight();
    int mapViewHeight = mapView.getMeasuredHeight();

    int mapViewCenter = (int)(mapViewHeight/2);
    int scrollMapHeight = (mapViewCenter + ((int)((mapViewHeight*y)/scrollLength)));

    scrollMapHeight = (int)((mapViewCenter - scrollMapHeight)/(1.5));

    if(scrollMapHeight<0)           
    mapView.scrollTo(x, scrollMapHeight);       
}
