我想在菜单按钮中选择操作时更改主面板内容。像主要内容页面，设置页面，主面板上的内容页面一样（代码使用网格x：名称=＆＃34; main_ ~~~）使用它只能使3和控制能见度？或者可以在Android上使用包含xml和更改包含目标？（例如＆gt; includelayout =＆＃34; @ layout / app_bar_main＆＃34;）

Answer 1

您可以在窗口中定义框架，并在所需的页面之间导航：

<Frame Name="FrameWithinGrid" >  
</Frame>

和按钮单击，您只需导航：

private void button1_Click(object sender, RoutedEventArgs e)  
{  
   FrameWithinGrid.Navigate(new System.Uri("Page1.xaml",  
         UriKind.RelativeOrAbsolute));  
}
