Ext.dataview.ListView:禁用Overscroll？

Question

在sencha可滚动视图中,如Ext.dataview.ListView,我们总是可以滚动屏幕外的元素列表.

如果我举个例子:http://dev.sencha.com/deploy/touch/examples/production/kitchensink/#demo/list

有没有办法阻止列表项"Alana Wiersma"？我希望这个项目与"top <= 0px".

您的问题恰恰称为过度滚动.试试这个:

scrollable : {
  direction: 'horizontal',
  directionLock: true,
  momentumEasing:  {
     momentum: {
       acceleration: 30,
       friction: 0.5
     },
     bounce: {
        acceleration: 0.0001,
        springTension: 0.9999,
     },
     minVelocity: 5
  },
  outOfBoundRestrictFactor: 0   
  }
