[英]Xamarin Forms - Web View
Still trying to get my head around Xamarin Forms (iOS). 仍在努力吸引Xamarin Forms(iOS)。 I am working with the WorkingWithWebView template from the Xamarin Website which mostly works.
我正在使用大部分工作的Xamarin网站上的WorkingWithWebView模板。 But I am having trouble getting it to work when I remove the tab view off the App() class.
但是,当我从App()类中删除选项卡视图时,我很难使它工作。
Tab view (This is what works)
标签视图(这是可行的)
var tabs = new TabbedPage ();
tabs.Children.Add (new LocalHtml {Title = "Local" });
tabs.Children.Add (new LocalHtmlBaseUrl {Title = "BaseUrl" });
tabs.Children.Add (new WebPage { Title = "Web Page"});
tabs.Children.Add (new WebAppPage {Title ="External"});
MainPage = tabs;
And when I go to LocalHtmlBaseUrl everything works as expected. 当我转到LocalHtmlBaseUrl时,一切正常。
But what I am wanting to do is load a page straight away without having a tabbed navigation on the bottom. 但是我想做的是立即加载页面,而底部没有选项卡式导航。
So far I have tried to do the following: 到目前为止,我已经尝试执行以下操作:
public App ()
{
//var tabs = new TabbedPage ();
//tabs.Children.Add (new LocalHtml {Title = "Local" });
//tabs.Children.Add (new LocalHtmlBaseUrl {Title = "BaseUrl" });
//tabs.Children.Add (new WebPage { Title = "Web Page"});
//tabs.Children.Add (new WebAppPage {Title ="External"});
//MainPage = tabs;
var parentpage = new Page();
var page = new WebView();
var browser = new BaseUrlWebView(); // temporarily use this so we can custom-render in iOS
var htmlSource = new HtmlWebViewSource();
htmlSource.Html = @"<html>
<head>
<link rel=""stylesheet"" href=""default.css"">
</head>
<body>
<h1>Xamarin.Forms</h1>
<p>The CSS and image are loaded from local files!</p>
<img src='XamarinLogo.png'/>
<p><a href=""index.html"">next page</a></p>
</body>
</html>";
htmlSource.BaseUrl = DependencyService.Get<IBaseUrl>().Get();
browser.Source = htmlSource;
page = browser;
parentpage = page;
MainPage = page;
}
At the parentpage = page - I get the error: 在父页面=页面上 -我收到错误消息:
Cannot implicitly convert type 'Xamarin.Forms.WebView' to 'Xamarin.Forms.Page'
无法将类型“ Xamarin.Forms.WebView”隐式转换为“ Xamarin.Forms.Page”
So the point of this thesis! 因此,本文的重点! I am just wanting to load that local html code that is specified in htmlSource.Html
我只想加载htmlSource.Html中指定的本地html代码
Thanks 谢谢

your browser needs to be contained within a page 您的浏览器需要包含在页面中
var browser = new BaseUrlWebView();
// do your other browser setup logic here
MainPage = new ContentPage { Content = browser };
