Hi, thanks for contribution! It looks good, I have tested it and it is working on Android. It would be nice to have such functionality also in holo picker. |

onLayoutis only called when the position is changed within the parent container, but if the parent container itself moves, it's not called. This makesthis._page{X,Y}be out of date. In my case, I have a draggable 'window' as the parent of the color picker and moving it around isn't updatingthis_page{X,Y}. This change makes it sothis_page{X,Y}is computed whenever a new color picking gesture begins so that it's always up to date (unless the color picker moves while gesturing but we can take care of that later...).
