Android: HorizontalScrollView inside ScrollView

Question

I have multiple HorizontalScrollViews inside a ScrollView. Horizontal scroll isn\'t smooth at all. I have to scroll almost perfectly horizontal

Answer 1

This class creates a ScrollView containing a HorizontalScrollView combined into one class. You can put stuff inside it using the AddChild() method. The dispatchTouchEvent overide keeps the scrolling smooth so you can pan around with a single slide of the finger.

(I recently used this to wrap a programmatically created TextView)

class MultiScrollView extends ScrollView
{           
 public HorizontalScrollView hscroll;

 public MultiScrollView ( Context context ) 
 { 
   super( context );
 }

 public void AddChild( View child ) 
 {                                              
   hscroll.addView( child );
 }

 @Override
 public boolean dispatchTouchEvent( MotionEvent event ) 
 {
   hscroll.dispatchTouchEvent(event);
   onTouchEvent(event);
   return true;
 }
}
