我是通用应用程序开发的新手,我有一个每页有4个按钮的flipview,每个按钮都有一个图像(总共8个图像),我创建了一个包含图像列表及其URls的模型类:
public class SampleItem
{
public string Image1 { get; set; }
public string Image2 { get; set; }
public string Image3 { get; set; }
public string Image4 { get; set; }
public string Image5 { get; set; }
public string Image6 { get; set; }
public string Image7 { get; set; }
public string Image8 { get; set; }
}
public class ButtonImages
{
public List<SampleItem> SampleItems { get; set; }
public ButtonImages()
{
SampleItems = new List<SampleItem>();
SampleItems.Add(new SampleItem()
{
Image1 = "images/1.png"
});
SampleItems.Add(new SampleItem()
{
Image2 = "images/2.png"
});
SampleItems.Add(new SampleItem()
{
Image3 = "images/3.png"
});
...........//all the 8 images URIs
然后我定义了名为flipview1的flipview:
<Page.Resources>
<DataTemplate x:Key="FlipViewItemTemplate">
<Grid >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Button Grid.Column="0" Grid.Row="0" >
<Image Source="{Binding Image1}"/>
</Button>
<Button Grid.Column="1" Grid.Row="0">
<Image Source="{Binding Image2}" />
</Button>
<Button Grid.Column="0" Grid.Row="1">
<Image Source="{Binding Image3}"/>
</Button>
<Button Grid.Column="1" Grid.Row="1">
<Image Source="{Binding Image4}"/>
</Button>
</Grid>
</DataTemplate>
</Page.Resources>
<FlipView x:Name="flipView1" ItemTemplate="{StaticResource FlipViewItemTemplate}"/>
这是我尝试获取8张图片并将它们放在每个页面的每个4个按钮中:
private void getimages()
{
List<ButtonImages> T = new List<ButtonImages>();
ButtonImages a;
if(true)
{
a = new ButtonImages();
T.Add(a);
}
flipView1.ItemsSource = T;
}
但我得到8页,每页有4个按钮,每个页面中有一个按钮有一个图像,其他页面是空的:(
我调试了代码,并将T中的所有图像作为列表 你有什么想法我怎么能纠正代码
感谢您的帮助
答案 0 :(得分:1)
首先,如果您希望每个FlipView页面有4张图片,则while(! word.equals("DONE"))
{
System.out.print("Please enter a word or DONE to exit: ");
word = keyboard.next();
if(!word.equals("DONE"))
{
if(shortest != null){
if (word.length() < shortest.length())
{
shortest = word;
}
}else{
shortest = word;
}
if (word.length() > longest.length())
{
longest = word;
}
wordcount ++;
}
}
应包含4张图片路径:
SampleItem
其次,如果您想要2个包含4个图像的页面,则应创建包含2个public class SampleItem
{
public string Image1 { get; set; }
public string Image2 { get; set; }
public string Image3 { get; set; }
public string Image4 { get; set; }
}
SampleItem
最后你应该为你的FlipView设置ItemsSource
var page1 = new SampleItem()
{
Image1 = "images/bar.png",
Image2 = "images/cuisine.png",
Image3 = "images/events.png",
Image4 = ""//path to 4th image on 1st page
};
var page2 = new SampleItem()
{
Image1 = "",//path to 1st image on 2nd page,
Image2 = "",//path to 2nd image on 2nd page,
Image3 = "",//path to 3rd image on 2nd page,
Image4 = ""//path to 4th image on 2nd page
};
var pages = new List<SampleItem>()
{
page1,
page2
};
您的代码无法正常工作,因为您创建了包含8个元素的列表,并且每个元素只有一个Image属性设置。这就是为什么你得到8页并且只显示一个图像的原因。
