Xamarin使用按钮调用TabbedPage [英] Xamarin Calling a TabbedPage using a Button
问题描述
我有问题.当我单击其他页面上的按钮时,我想加载TabbedPage,所以我创建了以下代码:
I have a problem. I want to load a TabbedPage when I click on a button in a different page, so I created this code:
protected void imgAdd_Clicked(object sender, EventArgs args)
{
var tabbedPage = new TabbedPage();
tabbedPage.Children.Add(new Page1());
tabbedPage.Children.Add(new Page2());
App.Current.MainPage = tabbedPage;
}
但是结果如下:
如您所见,在页面之间滑动时,图像会留下图像痕迹.
As you can see the Image leaves a trail of the image when you swipe between the pages.
但是,当我使用App.xaml.cs加载选项卡式页面时,它会正确加载而不会闪烁,因此看来只有在我从另一个页面调用选项卡式页面时才会发生...
However, when I load the Tabbed Page using the App.xaml.cs it loads correctly without the flickering, so it seems to only occur when I call the tabbed page from another page...
有什么想法吗?
推荐答案
我制作了要测试的示例.您可以在我的github上检查示例TabbedPageDemo

创建两个页面.
Page1.xaml:
Page1.xaml:
<StackLayout >
<Image Source="pig.jpg"></Image>
</StackLayout>
Page2.xaml:
Page2.xaml:
<StackLayout>
<Image Source="world.jpg"></Image>
</StackLayout>
使用您提供的代码.
var tabbedPage = new TabbedPage();
tabbedPage.Children.Add(new Page1());
tabbedPage.Children.Add(new Page2());
App.Current.MainPage = tabbedPage;
结果:
