Question

我正在使用visual studio 2017，我创建了一个带有可移植类库的共享项目，我将以下代码添加到MainPage.xaml.cs类文件中，

var scroll = new ScrollView();
Content = scroll;
var stack = new StackLayout();

stack.Children.Add(new BoxView { BackgroundColor = Color.Red,   HeightRequest = 600, WidthRequest = 600 });

stack.Children.Add(new Entry());

content=stack ;

然后我部署了项目，并在本地机器上运行它，我发现滚动不起作用。我在这里错过了什么？请帮忙。感谢。

Answer 1

您没有将stack添加到滚动条中。像这样编辑：

var scroll = new ScrollView();
var stack = new StackLayout();

stack.Children.Add(new BoxView { BackgroundColor = Color.Red,   HeightRequest = 600, WidthRequest = 600 });

stack.Children.Add(new Entry());

// Note how I add the stack object to the ScrollView here
scroll.Content = stack;

// And add the ScrollView to the Content of the page instead of the stack
Content = scroll;

Answer 2

试试这个

var stack = new StackLayout（）;

stack.Children.Add（new BoxView {BackgroundColor = Color.Red，HeightRequest = 600，WidthRequest = 600}）;

stack.Children.Add（new Entry（））;

Content = new ScrollView {Content = stack}

Xamarin.form Scrollview无效
