Fixes a regression from Froyo. Previously, when a scroll view had no children, its onTouchEvent would return because the scroll view would only start dragging if the user touched one of its children. In Gingerbread, the user can drag from anywhere within the scroll view, not just by touching a child. However, it makes no sense to drag a scroll view that has no children so an empty scroll view should just ignore touches like any other empty view group would. This change fixes applications that for some reason or other happen to have empty scroll views in strange places. Bug: 3246230 Change-Id: Iada6e886e8363e6778f42fc4861de228512d8bed
