屏幕会自动返回到之前的位置并且滚动未完成.它只是向下移动然后像弹性一样返回

The Screen automatically goes back to its previous location and the scroll is not complete. It just moves down and than back again like an elastic

推荐答案

你的 Grid，它是 ScrollViewer 的唯一子元素，具有 1768 的固定高度.这决定了 ScrollViewer 可以向上/向下滚动的最大区域.

Your Grid, that is the only child of the ScrollViewer, has a fixed height of 1768. That determines the maximum area that can be scrolled up/down by the ScrollViewer.

默认情况下，您的 ScrollViewer 会拉伸以适合其父级.该父元素是另一个 Grid，其高度也固定为 1768.

Your ScrollViewer stretches to fit its parent by default. That parent is another Grid that also has a fixed height of 1768.

因此 ScrollViewer 的高度也是固定的 1768，所以没有什么可以滚动的. 可滚动的数量是 ScrollViewer 高度和内容高度.在这种情况下，差异为 0.

Therefore the ScrollViewer has a fixed height of 1768 as well, so there is nothing to scroll. The amount available to scroll is the difference between the ScrollViewer height and the content height. In this case the difference is 0.

去掉外格的固定高度.我怀疑你的 Windows Phone 有 1768 高的屏幕 :)

Remove the fixed height of the outer Grid. I doubt your Windows Phone has a 1768 high screen :)
