我有一个来自实验室的混合web视图，它调用JS并显示返回。。。它是在模拟器和其他设备，如三星Galaxy S5工作。。。但在我的Galaxy S2和索尼Xperia上，它不起作用。。。。删除了一些不重要的代码

我的班级：

public class TestPage : ContentPage
{


    HtmlWebViewSource hwvsource = new HtmlWebViewSource();


    HybridWebView hwv = new HybridWebView() { VerticalOptions = LayoutOptions.FillAndExpand, HorizontalOptions = LayoutOptions.FillAndExpand };

    StackLayout stack = new StackLayout { VerticalOptions = LayoutOptions.FillAndExpand, HorizontalOptions = LayoutOptions.FillAndExpand };


    public TestPage ()
    {



        this.hwv.RegisterCallback ("dataCallback", JSCallback);

        //script that receives a list and call Native('dataCallback', list); ....
    this.hwvsource.Html = @"
            <!DOCTYPE html>
                <html>
                    <head>
                     <script language=""javascript"">
                    Native('dataCallback', list);
                   </script>
                    </head>  
                 </html>";

        this.hwv.Source = hwvsource;


        stack.Children.Add(activityIndicator);
        stack.Children.Add(hwv);
        stack.Children.Add(listView);

        this.Content = stack;

        this.hwv.LoadFinished += (object sender, EventArgs e) =>
        {

            this.hwv.IsVisible = false;
        }; 



    }


    private void JSCallback(string result){
        DisplayAlert ("callback", result, "ok");

    }


}

我是怎么说的，它在其他设备上运行良好，但S2除外

你知道会是什么吗？

你在S2上有什么Android版本？我刚刚发现是什么导致了这个问题。。。在javascript中，我传递了纬度和经度。我的s2的格式是xx，xxxx，其他设备的格式是xx.xxxx。。。。只是逗号和点之间的区别。。。我刚刚替换为Latitude.ToString（）.Replace（“，”，“。”），它成功了！！Tks！
