我想要一个像上面(所需的设计(一样的页脚结构在我的应用程序中,它有两个宽度为 50% 的按钮,上面有 fb 和谷歌图像。但是我无法设置图像的高度。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>
解决方法
1.您可以通过点击手势使用图像控制:
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);
2. 参考 https://github.com/XLabs/Xamarin-Forms-Labs/wiki/ImageButton
您可以在代码中添加HeightRequest,如下所示:
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,您的代码包含堆栈布局,它也可以修改结果。
2,如果您想更好地控制图像大小和位置,可以为其添加点击手势识别器。
。.CS
TapGestureRecognizer tapEvent = new TapGestureRecognizer();
tapEvent.Tapped += Button_Clicked;
imageBtn.GestureRecognizers.Add(tapEvent);
