我正在开发跨平台的xamarin应用程序,并且我想为“忘记密码?”创建超链接标签。在登录页面。 我已经使用下面的代码来创建标签,但我不知道如何创建onclick事件。如何在xamarin表单中的标签上创建点击事件动态
MainPage = new ContentPage
{
BackgroundImage = "background.png",
Content = new StackLayout
{
VerticalOptions = LayoutOptions.CenterAndExpand,
HorizontalOptions = LayoutOptions.CenterAndExpand,
Spacing = 50,
Children = {
new Label {
HorizontalTextAlignment = TextAlignment.Center,
Text = "Welcome, Please Sign in!",
FontSize=50,
TextColor=Color.Gray,
},
new Entry
{
Placeholder="Username",
VerticalOptions = LayoutOptions.Center,
Keyboard = Keyboard.Text,
HorizontalOptions = LayoutOptions.Center,
WidthRequest = 350,
HeightRequest = 50,
FontSize=20,
TextColor=Color.Gray,
PlaceholderColor=Color.Gray,
},
new Entry
{
Placeholder="Password",
VerticalOptions = LayoutOptions.Center,
Keyboard = Keyboard.Text,
HorizontalOptions = LayoutOptions.Center,
WidthRequest = 350,
HeightRequest = 50,
FontSize=25,
TextColor=Color.Gray,
IsPassword=true,
PlaceholderColor =Color.Gray,
},
new Button
{
Text="Login",
FontSize=Device.GetNamedSize(NamedSize.Large,typeof(Button)),
HorizontalOptions=LayoutOptions.Center,
VerticalOptions=LayoutOptions.Fill,
WidthRequest=350,
TextColor=Color.Silver,
BackgroundColor=Color.Red,
BorderColor=Color.Red,
},
new Label //for this label I want to create click event to open new page
{
Text="Forgot Password?",
FontSize=20,
TextColor=Color.Blue,
HorizontalOptions=LayoutOptions.Center,
},
}
}
};
对不起,但这段代码不适合我,原因是什么? ();}};' '私人异步无效lblLogin_Clicked(){等待Navigation.PushAsync(新的LoginPage()){ );}' –
如果你不使lblLogin异步,会发生什么?或者让你的命令异步并等待在lblLogin上? – noelicus
