首先,尝试定义索引以检测要选择的单元格。然后通过按钮点击更改索引,如:

int selectedIndex = 0;
private void MyBtn_Clicked(object sender, EventArgs e)
{
    if (selectedIndex == dataList.Count) selectedIndex = 0;
    myListView.SelectedItem = dataList[selectedIndex++];
}

when the TextCell is selected the ListView's ItemSelected event will fire, you can put your code in it like:

当选择TextCell时,ListView的ItemSelected事件将触发,您可以将代码放入其中:

private void MyListView_ItemSelected(object sender, SelectedItemChangedEventArgs e)
{
    //try to do something
}

这是我的代码,你指的是:

ObservableCollection dataList = new ObservableCollection();

int selectedIndex = 0;

public MainPage()
{
    InitializeComponent();

    for (int i=0; i<10; i++)
    {
        dataList.Add("item" + i);
    }

    myListView.ItemsSource = dataList;

    myListView.ItemSelected += MyListView_ItemSelected;

    MyBtn.Clicked += MyBtn_Clicked;
}

private void MyListView_ItemSelected(object sender, SelectedItemChangedEventArgs e)
{
    //try to do something
}

private void MyBtn_Clicked(object sender, EventArgs e)
{
    if (selectedIndex == dataList.Count) selectedIndex = 0;
    myListView.SelectedItem = dataList[selectedIndex++];
}
