你需要使用ListViews currentItem property：

You need to use the ListViews currentItem property: http://msdn.microsoft.com/en-us/library/windows/apps/hh700672.aspx

具体来说，为它指定一个索引为您想要选择的数据项（来自您的数据源），以及 hasFocus 和 showFocus 属性设置：

Specifically, assign it an object with the index of the data item you want selected (from your data source), and the hasFocus and showFocus properties set:

var yourListView = getYourListViewFromSomewhere();
yourListView.currentItem = { index: 8, hasFocus: true, showFocus: true }
