I have bing map controll in which so many maplayer are there
I want to display popup in my pushpin click event same like this
Bing Maps Gets New Look for Pushpins, Popups, And Transit - See more at: http://wmpoweruser.com/bing-maps-gets-new-look-for-pushpins-popups-and-transit/#sthash.ApL3q6bA.dpuf
How i can do this.
Give me some advice for developing popup in bing map controll and yes i want to show latitude,longlatitude and address in this popup
Mu pushin code
void _ClsGetDeviceMap_WorkFinished(bool success)
{
try
{
if (ClsGetDeviceMap.lstresponsecode.ElementAt<string>(0).Trim() == "1")

MessageBox.Show(ClsGetDeviceMap.lstresponsemsg.ElementAt<string>(0));
for (int i = 0; i <= ClsGetDeviceMap.lstLongLatitude.Count - 1; i++)
{
string lat, lon;
lat = ClsGetDeviceMap.lstLatitude.ElementAt<string>(i).Trim();

I am using Xamarin.Android to use inbuilt camera app to take a photo
but there are two missed things that I cant do and I have been googling them for long time:
I want to get a msg or popup (anything) after pressing the button to take a photo like "photo taken"
I want to let the user focus on any point of the camera - TAP TO FOCUS
async void TakePhotoButtonTapped(object sender, EventArgs e)
{
camera.StopPreview();
Android.Hardware.Camera.Parameters parameters = camera.GetParameters();
parameters.FocusMode = global::Android.Hardware.Camera.Parameters.FocusModeAuto;
camera.SetParameters(parameters);
var image = textureView.Bitmap;
try
{
var absolutePath = Android.OS.Environment.GetExternalStoragePublicDirectory(Android.OS.Environment.DirectoryDcim).AbsolutePath;
var folderPath = absolutePath + "/Camera";
var filePath = System.IO.Path.Combine(folderPath, string.Format("photo_{0}.jpg", Guid.NewGuid()));
var fileStream = new FileStream(filePath, FileMode.Create);
await image.CompressAsync(Bitmap.CompressFormat.Jpeg, 92, fileStream);
fileStream.Close();
image.Recycle();
var intent = new Android.Content.Intent(Android.Content.Intent.ActionMediaScannerScanFile);
var file = new Java.IO.File(filePath);
var uri = Android.Net.Uri.FromFile(file);
intent.SetData(uri);
MainActivity.Instance.SendBroadcast(intent);
}
catch (Exception ex)
{
System.Diagnostics.Debug.WriteLine(#" ", ex.Message);
}
camera.StartPreview();
}
I tried this but not working:
public void OnAutoFocus(bool success, Android.Hardware.Camera camera)
{
var parameters = camera.GetParameters();
if (parameters.FocusMode != Android.Hardware.Camera.Parameters.FocusModeContinuousPicture)
{
parameters.FocusMode = Android.Hardware.Camera.Parameters.FocusModeContinuousPicture;
if (parameters.MaxNumFocusAreas > 0)
{
parameters.FocusAreas = null;
}
camera.SetParameters(parameters);
camera.StartPreview();
}
}
public bool OnTouch(Android.Views.View view, MotionEvent e)
{
if (camera != null)
{
var parameters = camera.GetParameters();
camera.CancelAutoFocus();
Rect focusRect = CalculateTapArea(e.GetX(), e.GetY(), 1f);
if (parameters.FocusMode != Android.Hardware.Camera.Parameters.FocusModeAuto)
{
parameters.FocusMode = Android.Hardware.Camera.Parameters.FocusModeAuto;
}
if (parameters.MaxNumFocusAreas > 0)
{
List<Area> mylist = new List<Area>();
mylist.Add(new Android.Hardware.Camera.Area(focusRect, 1000));
parameters.FocusAreas = mylist;
}
try
{
camera.CancelAutoFocus();
camera.SetParameters(parameters);
camera.StartPreview();
camera.AutoFocus(this);
}
catch (System.Exception ex)
{
Console.WriteLine(ex.ToString());
Console.Write(ex.StackTrace);
}
return true;
}
return false;
}
private Rect CalculateTapArea(object x, object y, float coefficient)
{
var focusAreaSize = 500;
int areaSize = Java.Lang.Float.ValueOf(focusAreaSize * coefficient).IntValue();
int left = clamp((int) x - areaSize / 2, 0, textureView.Width - areaSize);
int top = clamp((int) y - areaSize / 2, 0, textureView.Height - areaSize);
RectF rectF = new RectF(left, top, left + areaSize, top + areaSize);
Matrix.MapRect(rectF);
return new Rect((int) System.Math.Round(rectF.Left), (int) System.Math.Round(rectF.Top), (int) System.Math.Round(rectF.Right),
(int) System.Math.Round(rectF.Bottom));
}
private int clamp(int x, int min, int max)
{
if (x > max)
{
return max;
}
if (x < min)
{
return min;
}
return x;
}
For focusing the camera when touching the preview you will need to:
Add a touch event handler to listen for the user touching the preview
Get the X and Y coordinates from that touch event, which are usually in the event arguments
Create a rectangle to focus to tell the Android Camera where to focus and in which area
Set FocusAreas and MeteringAreas on Camera.Parameters from your rectangle
Set the new Camera.Parameters on the camera
Set a AutoFocus callback on the camera
When the callback triggers, remove the callback from the camera, and cancel auto focus
To notify the user about a picture being taken, you can use a Toast or create a area in your preview where you want to show such messages. It is entirely up to you how you want to notify the user.
I want to get all entry controls value on button click.
My code is as below - this is how I am adding dynamic control on page:
public BookSeat()
{
ScrollView scroll = new ScrollView();
StackLayout stack = new StackLayout();
int count = Convert.ToInt32(Application.Current.Properties["NoPersonEntry"]);
for (int i = 0; i < count; i++)
{
stack.Children.Add(
new StackLayout()
{
Children = {
new Label (){TextColor = Color.Blue, Text = "First Name: ", WidthRequest = 100,StyleId="FnameLabel"+i },
new Entry() {StyleId="FnameEntry"+i }
}
}
);
}
Button button = new Button
{
Text = "Save"
};
button.Clicked += OnButtonClicked;
stack.Children.Add(button);
scroll.Content = stack;
this.Content = scroll;
}
And below code is for I want to get value on button click
public void OnButtonClicked(object sender, EventArgs e)
{
// Here I want to get value
}
What you can do is to store your entries in a list so that you can access them later on.
For example :
private List<Entry> _myentries = new List<Entry>();
public BookSeat()
{
ScrollView scroll = new ScrollView();
StackLayout stack = new StackLayout();
int count = Convert.ToInt32(Application.Current.Properties["NoPersonEntry"]);
for (int i = 0; i < count; i++)
{
var entry = new Entry() {StyleId="FnameEntry"+i };
_myentries.Add(entry);
stack.Children.Add(
new StackLayout()
{
Children = {
new Label (){TextColor = Color.Blue, Text = "First Name: ", WidthRequest = 100,StyleId="FnameLabel"+i },
entry
}
}
);
}
[...]
}
Now you can do this :
public void OnButtonClicked(object sender, EventArgs e)
{
foreach(var entry in _myentries)
{
var text = entry.Text;//here we go
}
}
I am creating an application in Xamarin.I want to use Auto-Scroll feature and i am not able to do that in a proper way. I am able to scroll manually. BUt i want to display the next picture automatically without scrolling.
Kindly share your views and codes.
I have used sliders for now. But i would like to know if i can do something better.
Grid SliderGrid = new Grid ();
//SliderGrid.BackgroundColor = Color.Black;
//SliderGrid.Padding = 10;
int SlidercolumnCount = Slider.Count;
RowDefinition Sliderrow = new RowDefinition ();
SliderGrid.RowDefinitions.Add (Sliderrow);
for (int j = 0; j < SlidercolumnCount; j++) {
ColumnDefinition col = new ColumnDefinition ();
SliderGrid.ColumnDefinitions.Add (col);
}
for (int i = 0; i < SlidercolumnCount; i++) {
var vetImageCol = new Image {
HeightRequest=260,
WidthRequest=360,
BindingContext = Slider [i],
Source = Slider [i].CategoryImage,
Aspect=Aspect.AspectFill,
};
Grid.SetColumn (vetImageCol, i);
SliderGrid.Children.Add (vetImageCol);
}
var SliderContent = new ScrollView {
Orientation=ScrollOrientation.Horizontal,
HorizontalOptions=LayoutOptions.FillAndExpand,
//HeightRequest=265,
Content= SliderGrid,
};
It's ok to do it with Task commands like this one:
private async void DoSomethingAsync()
{
await Task.Delay(1000);
DoSomething();
await Task.Delay(1000);
DoSomethingelse();
}
Although it's better to do it with Task return value instead of void but you get the idea
//page view is may ui scroll view
//counter for if my image focus on last image then return on 1 img
//new PointF((float)(your image size * count),your top margin or your fram y);
int count = 0;
public async void StartTimer()
{
await Task.Delay(3000); //3 sec
count += 1;
if (count == 5)
{
count = 0;
}
var bottomOffset = new PointF((float)(UIScreen.MainScreen.Bounds.Width * count),0);
pageview.SetContentOffset(bottomOffset, animated: true);
StartTimer();
}
public override void ViewDidLoad(){
StartTimer();
}
I have a list picker which is displayed in my phone application page.I have created list picker in starting of class,and i am adding the list picker in the phoneApplicationPage_loaded() method.When the page is launched the first time, ,the scenario works perfectly and its navigates further to second page.When i navigate back to previous page(containing list picker),it shows Invalid Operation Exception occured stating "Element is already the child of another element."
I want to know how to handle these scenarios?
Code is below
namespace My.Design
{
public partial class myclass : PhoneApplicationPage
{
String[] values = null;
ListPicker picker = new ListPicker();
StackPanel sp;
StackPanel mainFrame;
String statementInfo = "";
public myclass()
{
InitializeComponent();
}
private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e)
{
Debug.WriteLine("Phone Application Page Loaded_>>>>>>");
List<String> source = new List<String>();
displayUI();
}
public void displayUI()
{
Debug.WriteLine("About to display UI in miniStatement");
Debug.WriteLine("<-------------Data--------->");
Debug.WriteLine(statementInfo);
Debug.WriteLine("<-------------Data--------->");
int count = VisualTreeHelper.GetChildrenCount(this);
if (count > 0)
{
for (int i = 0; i < count; i++)
{
UIElement child = (UIElement)VisualTreeHelper.GetChild(this, i);
string childTypeName = child.GetType().ToString();
Debug.WriteLine("Elements in this Child" + childTypeName);
}
}
List<String> source = new List<String>();
String[] allParams = ItemString.Split('#');
source.Add("PleaseSelect");
for (int i = 0; i < allParams.Length; i++)
{
Debug.WriteLine("All Params Length" + allParams[i]);
if (!(allParams[i].Equals("") && (!allParams[i].Equals(null))))
{
if (values != null)
{
Debug.WriteLine("Values length" + values.Length);
values[values.Length] = allParams[i];
}
else
{
Debug.WriteLine("Allparams Length" + allParams[i]);
source.Add(allParams[i]);
}
}
}
//picker = new ListPicker();
this.picker.ItemsSource = source;
mainFrame = new StackPanel();
TextBlock box = new TextBlock();
box.Text = "> DEmoClass";
box.FontSize = 40;
mainFrame.Children.Add(box);
Canvas canvas = new Canvas();
StackPanel sp = new StackPanel();
TextBlock box1 = new TextBlock();
box1.Text = "Number";
box1.HorizontalAlignment = HorizontalAlignment.Center;
box1.FontSize = 40;
SolidColorBrush scb1 = new SolidColorBrush(Colors.Black);
box1.Foreground = scb1;
sp.Children.Add(box1);
picker.Width = 400;
picker.Height = 150;
sp.Children.Add(picker);
Canvas.SetTop(sp, 150);
canvas.Children.Add(sp);
mainFrame.Children.Add(canvas);
this.ContentPanel1.Children.Add(mainFrame);
}
protected override void OnNavigatingFrom(System.Windows.Navigation.NavigatingCancelEventArgs e)
{
/*
Debug.WriteLine("OnNavigatingFrom>>>.>>MainPage");
if (sp != null)
{
sp.Children.Remove(picker);
}*/
base.OnNavigatingFrom(e);
}
}
}
If you are not intending to update the listpicker after navigating back from the second page add the following line in your Loaded event handler
private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e)
{
this.Loaded -= PhoneApplicationPage_Loaded;
Debug.WriteLine("Phone Application Page Loaded_>>>>>>");
List<String> source = new List<String>();
displayUI();
}
i don't know why you can not use that case when app resume from tombstoned.
error happened because when you back to your page , loaded event runs again.
by the way,
Application_Activated 's argument can tell you app resumes from tombstoned or not--.
if (e.IsApplicationInstancePreserved)
{
IsTombstoning = false;
}
else
{
IsTombstoning = true;
}
I'm curious why you're creating it in code and not leaving it in XAML? Also the error is coming from the fact that you're attempting to add it twice into a location that can probably only have a single content element. What's the higher level problem you're trying to solve?
I'm trying to display a list of positions (from a xml document:using xml reading) in a Bing map with WP7,using the method below, but it doesn't work.
When i tried to see what my function is reading, i found out that it's not extracting the Longitude.Where's the problem?
void frloc_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
if (e.Error == null)
{
ListBoxItem areaItem = null;
StringReader wkstream = new StringReader(e.Result);
XmlReader wkreader = XmlReader.Create(wkstream);
string areaName = String.Empty;
string Nom = String.Empty;
string Photo = String.Empty;
string Latitude = String.Empty;
string Longitude = String.Empty;
string Timing = String.Empty;
while (wkreader.Read())
{
if (wkreader.NodeType == XmlNodeType.Element)
{
switch (wkreader.Name)
{
case ("name"):
{
Nom = wkreader.ReadElementContentAsString();
areaItem = new ListBoxItem();
areaItem.Content = Nom;
} break;
case ("photo"):
{
Photo = wkreader.ReadElementContentAsString();
areaItem = new ListBoxItem();
areaItem.Content = Photo;
} break;
case ("latitude"):
{
Latitude = wkreader.ReadElementContentAsString();
areaItem = new ListBoxItem();
areaItem.Content = Latitude;
} break;
case ("longitude"):
{
Longitude = wkreader.ReadElementContentAsString();
areaItem = new ListBoxItem();
areaItem.Content = Longitude;
} break;
}
double lat, lon;
double.TryParse(Latitude, NumberStyles.Any, CultureInfo.InvariantCulture, out lat);
double.TryParse(Longitude, NumberStyles.Any, CultureInfo.InvariantCulture, out lon);
GeoCoordinate Loc = new GeoCoordinate(lat, lon);
Pushpin wkpin = new Pushpin();
Image wkpinImage = new Image();
wkpin.Content = Nom;
wkpinImage.Source = new System.Windows.Media.Imaging.BitmapImage(new Uri("http://weenek.com/markers/" + Photo, UriKind.Absolute));
wkpinImage.Opacity = 0.8;
wkpinImage.Stretch = System.Windows.Media.Stretch.None;
imageLayer.AddChild(wkpinImage, Loc);
map1.Children.Add(wkpin);
The xml:
<resultat>
<ami>
<id>547</id>
<nom>Hakim</nom>
<prenom>Abidi</prenom>
<latitude>37.01406741589469</latitude>
<longitude>11.02375026562504</longitude>
<date>2011-12-02</date>
<time>01:09:35</time>
<image>175.jpg</image>
</ami>
</resultat>
There's nothing wrong with your code except of that you're never setting the coordinates of the Pushpin.
Try adding
wkpin.Location = Loc;
