Scrolling with Multiple ListViews for Android

Question

I'm completely stumped on this one. I have three different lists that need to be displayed on the screen. It's completely possible that the lists will extend past the bottom edge of the screen, so I would need scrolling.

I've tried using a ScrollView with a LinearLayout child, and putting my ListViews in the LinearView, but all of the ListViews lock to a fixed height with scroll bars. Using other kinds of Layouts means no scrolling.

Does anyone have any suggestions, or will I need to programmatically add the list items to some layout and hope for the best?

Forward touch event from touched view to other views. All your views will be synchronized expand/collapsed too.

   OnTouchListener mOnTouch = new OnTouchListener()     {         @Override         public boolean onTouch(View v, MotionEvent event)         {                         MotionEvent newEvent = MotionEvent.obtain(event);             switch(event.getAction()){               case MotionEvent.ACTION_MOVE:                 if(mTouched == null){                     mTouched = v;                 }                 mMovingFlag = true;                 break;             case MotionEvent.ACTION_UP:                 if(mMovingFlag==false){                     newEvent.setAction(MotionEvent.ACTION_CANCEL);                 }                 mMovingFlag = false;                 break;             default:                 mMovingFlag = false;                 if(mTouched != null && mTouched.equals(v)){                     mTouched = null;                 }                 break;              }             if(mTouched == null || mTouched.equals(v)){                 int items = mLayoutWithListViews.getChildCount();                 for(int list=0; list<items; list++){                     AbsListView listView =mLayoutWithListViews.getChildAt(list));                     if(listView != v){                          listView.onTouchEvent(newEvent);                     }                 }             }             return false;         }     };

I haven't done this yet, but I've been thinking about it since I'll probably need to do it. I can think of three options: use only one list with the contents of all lists. You can make a ListAdapter that does that and inserts some kind of header. This could probably be something very re-usable.

The other idea is to make a list of lists. But that sounds like asking for trouble.
