I want to show image on whole screen if someone clicks on it. Image is loaded from database, just url of that image. How can i do that, code looks like this.
public void GetAllPlanes()
{
string _dbPath = Path.Combine(System.Environment.GetFolderPath(System.Environment.SpecialFolder.Personal), "myDB.db3");
var db = new SQLiteConnection(_dbPath);
for (int a = 1; a <= DatabaseNmbr(); a++)
{
var rowData = db.Table<Airplane>().FirstOrDefault(i => i.Id == a);
if (rowData.Plane != null && rowData.Airline != null && rowData.Registration != null && rowData.Registration != null && rowData.Airport != null && rowData.Url != null)
{
//vzhled
Frame cardFrame = new Frame
{
BackgroundColor = Color.FromHex("#00d2ff"),
CornerRadius = 30,
Margin = new Thickness(0, 60, 0, -20),
Content = new StackLayout
{
Children =
{
new Label {Text = "Plane " + a, TextColor = Color.White, HorizontalOptions = LayoutOptions.Center, FontSize = 30 },
new Image { Source = rowData.Url },
new Label {Text = "Plane:" + rowData.Plane, TextColor = Color.White, FontSize = 20 },
new Label {Text = "Airline:" + rowData.Airline, TextColor = Color.White, FontSize = 15 },
new Label {Text = "Livery:" + rowData.Livery, TextColor = Color.White, FontSize = 15 },
new Label {Text = "Registration:" + rowData.Registration, TextColor = Color.White, FontSize = 15 },
new Label {Text = "Airport:" + rowData.Airport, TextColor = Color.White, FontSize = 15 },
new Label {Text = "Date:" + rowData.Date, TextColor = Color.White, FontSize = 15 },
new Label {Text = "Comment:" + rowData.Comment, TextColor = Color.White, FontSize = 15}
}
}
};
Contenttest.Children.Add(cardFrame);
}
}
}
I want to show image on whole screen if someone clicks on it.
You can add TapGestureRecognizer to Image, when you Tap in Image, navigating to another to display entire image.
ContentPage1:
public partial class Page1 : ContentPage
{
public Page1()
{
InitializeComponent();
for (int i=0;i<4;i++)
{
Image image = new Image { Source = "https://aka.ms/campus.jpg", HeightRequest = 100, WidthRequest = 100 };
var tapGestureRecognizer = new TapGestureRecognizer();
// tapGestureRecognizer.NumberOfTapsRequired = 2; // double-tap
tapGestureRecognizer.Tapped += OnTapGestureRecognizerTapped;
image.GestureRecognizers.Add(tapGestureRecognizer);
Frame cardFrame = new Frame
{
CornerRadius = 30,
Content = new StackLayout
{
Children =
{
new Label {Text="Panel "+i, HorizontalOptions = LayoutOptions.Center, FontSize = 30 },
image
}
}
};
Contenttest.Children.Add(cardFrame);
}
}
private async void OnTapGestureRecognizerTapped(object sender, EventArgs e)
{
var imageSender = (Image)sender;
await Navigation.PushAsync(new Page2(imageSender.Source));
}
}
ContentPage2:
<StackLayout>
<Image
x:Name="image1"
HorizontalOptions="FillAndExpand"
VerticalOptions="FillAndExpand" />
</StackLayout>
public partial class Page2 : ContentPage
{
public Page2(ImageSource source)
{
InitializeComponent();
image1.Source = source;
}
}
I ran into a curious problem: method ScrollTo doesn't work for the ListView inside root page initialized inside NavigationPage. The simple code:
public partial class MainPage : ContentPage
{
ListView listView;
public MainPage()
{
var abs = new AbsoluteLayout { };
var src = new List<string>();
for (int i = 0; i < 30; i++) { src.Add(i + 1 + " line"); }
abs.Children.Add(listView = new ListView { ItemsSource = src }, new Rectangle(0, 0, 1, 0.9), AbsoluteLayoutFlags.All);
abs.Children.Add(new Entry { BackgroundColor = Color.Gray }, new Rectangle(0, 1, 1, 0.1), AbsoluteLayoutFlags.All);
Content = abs;
}
protected override void OnAppearing()
{
base.OnAppearing();
var last = (listView.ItemsSource as List<string>).Last();
listView.ScrollTo(last, ScrollToPosition.End, false);
}
}
Here I try to scroll to the last element when the MainPage is loading. And that works fine if I has initialized App so:
public App ()
{
InitializeComponent();
MainPage = new App1.MainPage { Title = "Main" };
}
But if I put the MainPage inside NavigationPage, scrolling does not occur:
public App ()
{
InitializeComponent();
MainPage = new NavigationPage(new App1.MainPage { Title = "Main" });
}
What is the correct way to solve this?
PS: now I outflank this moment through Device.StartTimer, but I think this is wrong crutch
I am working on iOS Tabs using custom TabbedRenderer, In renderer page I am resizing & setting icons. But for the first Tab icon not getting resized rest of all tabs setting icons fine.
public class CustomTabRenderer_iOS : TabbedRenderer
{
public override void ViewWillLayoutSubviews()
{
base.ViewWillLayoutSubviews();
foreach (var item in TabBar.Items)
{
item.Image = GetTabIcon(item.Title);
}
}
private UIImage GetTabIcon(string title)
{
UITabBarItem item = null;
switch (title)
{
case "Dairy":
item = new UITabBarItem("Dairy", UIImage.FromFile("dairy"), 0);
break;
case "My kid":
item = new UITabBarItem("My kid",UIImage.FromFile("kid"),0);
break;
case "Events":
item = new UITabBarItem("Events", UIImage.FromFile("events"), 0);
break;
case "About":
item = new UITabBarItem("About", UIImage.FromFile("about"), 0);
break;
}
var img = (item != null) ? UIImage.FromImage(item.SelectedImage.CGImage, item.SelectedImage.CurrentScale, item.SelectedImage.Orientation) : new UIImage();
var imgR = ResizeImage(img, 20, 20);
return imgR;
}
public UIImage ResizeImage(UIImage sourceImage, float width, float height)
{
UIGraphics.BeginImageContext(new SizeF(width, height));
sourceImage.Draw(new RectangleF(0, 0, width, height));
var resultImage = UIGraphics.GetImageFromCurrentImageContext();
UIGraphics.EndImageContext();
return resultImage;
}
}
Below is TabbedPage from PCL project
<Shared:MyTabbedPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:local="clr-namespace:edTheSIS"
x:Class="edTheSIS.ParentDashboard"
xmlns:Shared="clr-namespace:edTheSIS.Shared;assembly=edTheSIS">
<local:DairyTabPage Icon="dairy" HeightRequest="10" WidthRequest="10" ></local:DairyTabPage>
<local:MykidTab Icon="kid" ></local:MykidTab>
<local:Events Icon="events"></local:Events>
<local:About Icon="about"></local:About>
</Shared:MyTabbedPage>
See below screenshot
second screenshot below
According to the iOS Human Interface Guidelines, the images should be sizes as shown in the table underneath for a tab bar.
If you size the icons accordingly, they should always show right. There would be no reason to resize in code.
When you still want to use the code to resize an icon, update your ViewWillLayoutSubviews method like this, also setting the SelectedImage property:
public override void ViewWillLayoutSubviews()
{
base.ViewWillLayoutSubviews();
foreach (var item in TabBar.Items)
{
item.Image = GetTabIcon(item.Title);
item.SelectedImage = GetTabIcon(item.Title);
}
}
The tab bar icon size on iOS can be set with the UITabBarItem.ImageInset in a custom TabbedRenderer
[assembly: ExportRenderer(typeof(TabbedPage), typeof(CustomTabbedPageRenderer))]
namespace AppNameSpace.iOS.Renderers
{
class CustomTabbedPageRenderer : TabbedRenderer
{
public override void ViewDidLayoutSubviews()
{
base.ViewDidLayoutSubviews();
if (Element is TabbedPage)
if (TabBar?.Items != null)
foreach (var item in TabBar.Items)
item.ImageInsets = new UIEdgeInsets(16, 16, 16, 16);
}
}
}
I have a Xamarin.Forms (1.4.2.6359) Project using Visual Studio 2013 and have created the carousel page below. I want to add page indicators, i.e. dots over top of the carousel page. Is this able to be done with the Xamarin Forms CarouselPage?
public class SplashPage : CarouselPage
{
public SplashPage ()
{
this.Children.Add(new CarouselChild("Logo.png", "Welcome"));
this.Children.Add(new CarouselChild("Settings.png", "Settings"));
}
}
class CarouselChild : ContentPage
{
public CarouselChild(string image, string text)
{
StackLayout layout = new StackLayout
{
HorizontalOptions = LayoutOptions.CenterAndExpand,
VerticalOptions = LayoutOptions.CenterAndExpand,
};
layout.Children.Add(new Image
{
Source = image,
});
layout.Children.Add(new Label
{
HorizontalOptions = LayoutOptions.CenterAndExpand,
VerticalOptions = LayoutOptions.EndAndExpand,
Text = text,
Scale = 2,
});
this.Content = layout;
}
}
Trying to keep things simple, what I did was:
MyCarouselPage:
class MyCarouselPage : CarouselPage
{
private int totalPages;
private int currentPage;
public MyCarouselPage()
{
var pages = GetPages();
totalPages = pages.Length;
this.ChildAdded += MyCarouselPage_ChildAdded;
for (int i = 0; i < totalPages; i++)
{
currentPage = i;
this.Children.Add(pages[i]);
}
}
void MyCarouselPage_ChildAdded(object sender, ElementEventArgs e)
{
var contentPage = e.Element as MyPageBase;
if (contentPage != null)
{
contentPage.FinalStack.Children.Add(new CarouselPageIndicator(currentPage, totalPages, "indicator.png", "indicator_emtpy.png"));
}
}
private MyPageBase[] GetPages()
{
var pages = new MyPageBase[] { new Page1(), new Page2() };
return pages;
}
}
The Base class for the Pages
class MyPageBase:ContentPage
{
public StackLayout FinalStack { get; set; }
}
CarouselPageIndicator
public class CarouselPageIndicator : StackLayout
{
public CarouselPageIndicator(int currentIndex, int totalItems, string sourceIndicator, string souceEmptyIndicator)
{
this.Orientation = StackOrientation.Horizontal;
this.HorizontalOptions = LayoutOptions.CenterAndExpand;
for (int i = 0; i < totalItems; i++)
{
var image = new Image();
if (i == currentIndex)
image.Source = sourceIndicator;
else
image.Source = souceEmptyIndicator;
this.Children.Add(image);
}
this.Padding = new Thickness(10);
}
}
And for the n-Pages
class Page1:MyPageBase
{
public Page1()
{
var layout = new StackLayout
{
Children = {
new Label{Text="Page 1"}
}
};
this.FinalStack = layout;
this.Content = FinalStack;
}
}
I was able to make a work around for the problem by hard coding the page indicators by changing CarouselChild method below:
public CarouselChild(string image, string text, int pageNumber, int pageCount)
{
var width = this.Width;
StackLayout layout = new StackLayout
{
HorizontalOptions = LayoutOptions.FillAndExpand,
VerticalOptions = LayoutOptions.FillAndExpand,
Padding = new Thickness( 40, 40, 40, 40),
BackgroundColor = Color.Black,
};
layout.Children.Add(new Image
{
Source = image,
VerticalOptions = LayoutOptions.Start,
HorizontalOptions = LayoutOptions.Center,
});
layout.Children.Add(new Label
{
HorizontalOptions = LayoutOptions.CenterAndExpand,
Text = text,
FontSize = 36,
LineBreakMode = LineBreakMode.WordWrap,
});
layout.Children.Add(CarouselPageIndicator(pageNumber, pageCount));
this.Content = layout;
}
internal StackLayout CarouselPageIndicator(int pageNumber, int pageCount)
{
StackLayout layout = new StackLayout
{
Orientation = StackOrientation.Horizontal,
HorizontalOptions = LayoutOptions.CenterAndExpand,
VerticalOptions = LayoutOptions.EndAndExpand,
};
if (pageCount >= pageNumber)
{
for (int i = 1; i < pageCount + 1; i++)
{
if (i == pageNumber)
{
layout.Children.Add(new Image
{
Source = "Light.png",
});
}
else
{
layout.Children.Add(new Image
{
Source = "Dark.png",
});
}
}
}
return layout;
}
Below is the complete program (XAML and code behind). When started you will see:
When you click [Show/Hide] you see:
When you uncheck Home and Documents and click [Apply] you see:
As you can see, the Home and Documents folder disappear, but the other folders do not move up. Looking at the two list boxes you see three items per line, folder label, the value for Canvas.SetTop, and True: Visibility.Visible or False: Visibility.Collapsed. The Original Placement list box are the original values. Each time you click [Apply] the New Placement List box shows that new values. The Visibility value gets applied and the result is visible, either the folder is there or it is not. However, applying the Canvas.SetTop does not work. And you can see that the values have changed for the Canvas.SetTop. And, if you look at the code, you see that it is applied to the same UIElement as the Visibility is applied to:
var f = Me[i];
Canvas.SetTop(iec, f.Top); // Why does this not work and
iec.Visibility = f.FolderVisible; // this does work?
I need the folders that are visible to move up to take the place of those that are collapsed. Canvas.SetTop is not working. How can I get the Folders to move?

Thanks for any help that you can provide.
I finally figured out the answer, and it is very simple.
This is the code to be changed (the center line only):
var f = Me[i];
Canvas.SetTop(iec, f.Top); // Why does this not work
iec.Visibility = f.FolderVisible; // and this does work?
This is the new code (only the center line is changed, actually, only one character is removed):
var f = Me[i];
Canvas.SetTop(ie, f.Top);
iec.Visibility = f.FolderVisible;
That is, change Canvas.SetTop(iec, f.Top); to Canvas.SetTop(ie, f.Top); that is, only change iec to ie and all works fine.
