Scrollview vertical and horizontal in android

Question

I m really tired looking for a solution for vertical and horizontal Scrollview   I read that there are not any views layouts in the framework which implement this feature  but I need something like this   I need to define a layout within other  the child layout must implement scrolling vertical horizontal for moving   Initially implemented a code that moved the layout pixel by pixel  but I think that is not the right way  I tried it with ScrollView and Horizontal ScrollView but nothing works like I want it to  because it only implements vertical or horizontal scrolling   Canvas is not my solution because I need to attach listeners in someones child elements   What can I do

Option  1  You can come up with a new UI design that does not require simultaneous horizontal and vertical scrolling   Option  2  You can obtain the source code to ScrollView and HorizontalScrollView  learn how the core Android team implemented those  and create your own BiDirectionalScrollView implementation   Option  3  You can get rid of the dependencies that are requiring you to use the widget system and draw straight to the Canvas   Option  4  If you stumble upon an open source application that seems to implement what you seek  look to see how they did it

My solution based on Mahdi Hijazi answer  but without any custom views   Layout    lt HorizontalScrollView xmlns android  http   schemas android com apk res android       android id    id scrollHorizontal      android layout width  match parent      android layout height  wrap content  gt        lt ScrollView          android id    id scrollVertical          android layout width  wrap content          android layout height  match parent   gt            lt WateverViewYouWant  gt        lt  ScrollView gt   lt  HorizontalScrollView gt    Code  onCreate onCreateView        final HorizontalScrollView hScroll    HorizontalScrollView  value findViewById R id scrollHorizontal       final ScrollView vScroll    ScrollView  value findViewById R id scrollVertical       vScroll setOnTouchListener new View OnTouchListener       inner scroll listener                   Override         public boolean onTouch View v  MotionEvent event                return false                        hScroll setOnTouchListener new View OnTouchListener       outer scroll listener                  private float mx  my  curX  curY          private boolean started   false            Override         public boolean onTouch View v  MotionEvent event                curX   event getX                curY   event getY                int dx    int   mx - curX               int dy    int   my - curY               switch  event getAction                      case MotionEvent ACTION MOVE                      if  started                            vScroll scrollBy 0  dy                           hScroll scrollBy dx  0                         else                           started   true                                            mx   curX                      my   curY                      break                  case MotionEvent ACTION UP                       vScroll scrollBy 0  dy                       hScroll scrollBy dx  0                       started   false                      break                            return true                      You can change the order of the scrollviews  Just change their order in layout and in the code  And obviously instead of WateverViewYouWant you put the layout views you want to scroll both directions

Playing with the code  you can put an HorizontalScrollView into an ScrollView  Thereby  you can have the two scroll method in the same view   Source   http   androiddevblog blogspot com 2009 12 creating-two-dimensions-scroll-view html  I hope this could help you

since the Two Dimensional Scrollview link is dead I could not get it so I created my own component  It handles flinging and works properly for me  The only restriction is that wrap content might not work properly for that component   https   gist github com androidseb 9902093

I have a solution for your problem  You can check the ScrollView code it handles only vertical scrolling and ignores the horizontal one and modify this  I wanted  a view like a webview  so modified ScrollView and it worked well for me  But this may not suit your needs   Let me know what kind of UI you are targeting for   Regards   Ravi Pandit

Since this seems to be the first search result in Google for  Android vertical horizontal ScrollView   I thought I should add this here   Matt Clark has built a custom view based on the Android source  and it seems to work perfectly  Two Dimensional ScrollView  Beware that the class in that page has a bug calculating the view s horizonal width  A fix by Manuel Hilty is in the comments      Solution  Replace the statement on line 808 by the following   final int childWidthMeasureSpec   MeasureSpec makeMeasureSpec lp leftMargin   lp rightMargin  MeasureSpec UNSPECIFIED       Edit  The Link doesn t work anymore but here is a link to an old version of the blogpost
