Xamarin.form滾動型不工作

Question

我使用的Visual Studio 2017年，我創建了便攜式類庫共享項目，我加入到MainPage.xaml.cs中的類文件下面的代碼，

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 ;  

然後我部署了該項目，並在本地機器上運行它，發現滾動不起作用。 我在這裏錯過了什麼？ 請任何幫助。 謝謝。

Answer 1

您並未將stack添加到卷軸上。編輯這樣說：

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

試試這個

VAR堆棧=新StackLayout（）;

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

stack.Children.Add（new Entry（））;

Content = new ScrollView {Content = stack}
