[英]How to Open a web page with the click of a button in xamarin form
我有一個xamarin格式的文件稱為HomePage,它從用戶那里獲取eURL內容。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Xamarin.Forms;
namespace zaposta_angelar
{
public class HomePage : ContentPage
{
Label lTitle;
Entry eURL;
Button bButton;
public HomePage()
{
lTitle = new Label
{
Text = "WELCOME",
HorizontalOptions = LayoutOptions.Center,
FontAttributes = Font.SystemFontOfSize(25, FontAttributes.Bold).FontAttributes,
FontSize = Font.SystemFontOfSize(25, FontAttributes.Bold).FontSize,
//WidthRequest = 200,
HeightRequest = 100
};
eURL = new Entry { Placeholder = "Enter Site URL", };
bButton = new Button { Text = "ENTER", };
bButton.Clicked += bButton_Clicked;
this.Content = new StackLayout
{
Children = {
lTitle, eURL, bButton
}
};
}
void bButton_Clicked(object sender, EventArgs e)
{
if (String.IsNullOrEmpty(eURL.Text)) { DisplayAlert("URL", "Your URL is Empty", "OK"); }
else
{
SitePage.LoadRequest(new SitePage(eURL)));
}
}
}
}
並通過單擊按鈕bButton打開eURL,並將網站加載到另一個名為SitePage的頁面中
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Xamarin.Forms;
namespace zaposta_angelar
{
public class SitePage : NavigationPage
{
private Entry eURL;
public SitePage()
{
}
public SitePage(Entry eURL)
{
// TODO: Complete member initialization
this.eURL = eURL;
}
internal static void LoadRequest(SitePage sitePage)
{
throw new NotImplementedException();
}
}
}
該代碼無法正常工作
好吧,我不確定您打算走哪條路,但是您可以通過以下任一方式打開網頁
在內部使用WebView
使用Device.OpenUri
