<WebView Source="https://www.baidu.com">
</WebView>
可以用后台代码和webview互动，例如webview.Eval("alert(‘hello‘)");
xamarin.form原生webview有很多bug，建议使用第三方的view控件HybirdWebView
如果要使用这个view，需要安装XLabs.Serialization.JSON，和XLabs.Forms
然后在ios中将appdelegate修改为
// The UIApplicationDelegate for the application. This class is responsible for launching the
// User Interface of the application, as well as listening (and optionally responding) to
// application events from iOS.
[Register("AppDelegate")]
public partial class AppDelegate : XLabs.Forms.XFormsApplicationDelegate
{
//
// This method is invoked when the application has loaded and is ready to run. In this
// method you should instantiate the window, load the UI into it and then make the window
// visible.
//
// You have 17 seconds to return from this method, or iOS will terminate your application.
//
public override bool FinishedLaunching(UIApplication app, NSDictionary options)
{
SetIoc();
global::Xamarin.Forms.Forms.Init();
LoadApplication(new App());
return base.FinishedLaunching(app, options);
}
private void SetIoc()
{
var resolverContainer = new SimpleContainer();
resolverContainer.Register<IJsonSerializer, JsonSerializer>();
Resolver.SetResolver(resolverContainer.GetResolver());
}
}
在android中修改mainactive修改为
[Activity(Label = "App2", Icon = "@mipmap/icon", Theme = "@style/MainTheme", MainLauncher = true, ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation)]
public class MainActivity : XFormsApplicationDroid
{
protected override void OnCreate(Bundle savedInstanceState)
{
//TabLayoutResource = Resource.Layout.Tabbar;
//ToolbarResource = Resource.Layout.Toolbar;
SetIoc();
base.OnCreate(savedInstanceState);
global::Xamarin.Forms.Forms.Init(this, savedInstanceState);
LoadApplication(new App());
}
private void SetIoc()
{
var resolverContainer= new SimpleContainer();
resolverContainer.Register<IJsonSerializer, JsonSerializer>();
Resolver.SetResolver(resolverContainer.GetResolver());
}
}
LoadFinished事件加载完成事件
CallJsFunction("alert","你好");
在html中加入代码注册按钮回掉后台代码
function Callback(){
Native("datacallback","this is callback paramer");
}
然后在后台代码中加入
webView.RegisterCallback("datacallback",t=>{T就是参数});
