我想在我的应用程序中使用上面的页脚结构(所需的设计),该结构具有两个宽度为50%,fb和google图片的按钮。但是我不能设置图像的高度。请帮帮我
这是我尝试过的代码
<StackLayout>
<StackLayout Orientation="Horizontal" VerticalOptions="Start">
<!-- top controls -->
</StackLayout>
<StackLayout VerticalOptions="CenterAndExpand">
<!-- middle controls -->
</StackLayout>
<StackLayout Orientation="Horizontal" VerticalOptions="End">
<StackLayout Orientation="Horizontal" HorizontalOptions="FillAndExpand">
<StackLayout Orientation="Vertical" HorizontalOptions="FillAndExpand">
<Button Text="Has Image" Image="drawable/fb_btn.png"/>
</StackLayout>
<StackLayout Orientation="Vertical" HorizontalOptions="FillAndExpand">
<Button Text="Sign Up"/>
</StackLayout>
</StackLayout>
</StackLayout>
</StackLayout>

您可以像这样在代码中添加 HeightRequest :
XAML
<StackLayout Orientation="Vertical" HorizontalOptions="FillAndExpand">
<Button Name="imageBtn" Text="Has Image" Image="drawable/fb_btn.png"
HeightRequest="56"/>
</StackLayout>
更多信息:
1,您的代码包含StackLayout,它也可以修改结果。
2,如果要进一步控制图像的大小和位置,可以向其添加轻击手势识别器。
.CS
TapGestureRecognizer tapEvent = new TapGestureRecognizer();
tapEvent.Tapped += Button_Clicked;
imageBtn.GestureRecognizers.Add(tapEvent);

解决方法
1。您可以将Image控制与手势一起使用:
XAML
<Image x:Name="myImage" Source="myPicture.png" HeightRequest="150" WidthRequest="60" BackgroundColor="Red" HorizontalOptions="Center"/>
XAML.CS
TapGestureRecognizer tapEvent = new TapGestureRecognizer();
tapEvent.Tapped += clickedEvent;
myImage.GestureRecognizers.Add(tapEvent);
