I have a webview showing URL containing HTML5 content with video 360
public class HybridWebViewRenderer : WkWebViewRenderer
{
WKUserContentController userController;
public HybridWebViewRenderer() : this(new WKWebViewConfiguration())
{
}
public HybridWebViewRenderer(WKWebViewConfiguration config) : base(config)
{
userController = config.UserContentController;
}
protected override void OnElementChanged(VisualElementChangedEventArgs e)
{
base.OnElementChanged(e);
if (e.OldElement != null)
{
HybridWebView hybridWebView = e.OldElement as HybridWebView;
hybridWebView.Cleanup();
}
if (e.NewElement != null)
{
BackgroundColor = UIColor.Clear;
Opaque = false;
Configuration.AllowsInlineMediaPlayback = true;
Configuration.Preferences.JavaScriptEnabled = true;
Configuration.Preferences.JavaScriptCanOpenWindowsAutomatically = true;
}
}
public void DidReceiveScriptMessage(WKUserContentController userContentController, WKScriptMessage message)
{
((HybridWebView)Element).InvokeAction(message.Body.ToString());
}
protected override void Dispose(bool disposing)
{
if (disposing)
{
((HybridWebView)Element).Cleanup();
}
base.Dispose(disposing);
}
}
I got the video in the middle and when I double click on it
it shows as a separate window and could be closed
sorry I was mistaken of where to change configurations
it should be like that
public class HybridWebViewRenderer : WkWebViewRenderer
{
WKUserContentController userController;
static WKWebViewConfiguration config = new WKWebViewConfiguration()
{
AllowsAirPlayForMediaPlayback = false,
AllowsInlineMediaPlayback = true,
Preferences = new WKPreferences()
{
JavaScriptCanOpenWindowsAutomatically = true,
JavaScriptEnabled = true
}
};
public HybridWebViewRenderer() : this(config)
{
}
public HybridWebViewRenderer(WKWebViewConfiguration config) : base(config)
{
userController = config.UserContentController;
}
protected override void OnElementChanged(VisualElementChangedEventArgs e)
{
base.OnElementChanged(e);
if (e.OldElement != null)
{
HybridWebView hybridWebView = e.OldElement as HybridWebView;
hybridWebView.Cleanup();
}
if (e.NewElement != null)
{
BackgroundColor = UIColor.Clear;
Opaque = false;
}
}
public void DidReceiveScriptMessage(WKUserContentController userContentController, WKScriptMessage message)
{
((HybridWebView)Element).InvokeAction(message.Body.ToString());
}
protected override void Dispose(bool disposing)
{
if (disposing)

}
base.Dispose(disposing);

I'm trying make a Custom View in Xamarin Forms that translates to an UICollectionView in IOS.
This first thing is fairly simple to do:
View:
public class CollectionView : View
{
}
Renderer:
public class CollectionViewRenderer : ViewRenderer<CollectionView, UICollectionView>
{
protected override void OnElementChanged(ElementChangedEventArgs<CollectionView> e)
{
base.OnElementChanged(e);
if (Control == null)
{
SetNativeControl(new UICollectionView(new CGRect(0, 0, 200, 200), new UICollectionViewFlowLayout()));
}
if (e.NewElement != null)
{
...
Control.Source = new CollectionViewSource(a, this);
Control.ReloadData();
}
}
}
Now I would like to feed this CollectionView with DataTemplates (from a DataTemplateSelector). But I'm unable to find a way to register the classes:
From the template you can do:
Template.CreateContent();
to get the UI element.
But how can I register it in the collectionView for dequeue'ing in the CollectionSource
E.G.:
CollectionView.RegisterClassForCell(typeof(????), "CellId");
Hope, it will help you!!!

After updating the device to iOS 10, QLPreviewController stopped to display correctly the documents. It shows the white screen.
I have extracted the sample scenario from the app.
It contains single page with two buttons that should load two different documents:

<Button Text="Load second doc" Clicked="OnLoadSecondClicked"/>
<Button Text="Navigate forward" Clicked="OnForwardClicked"/>
<local:QLDocumentView
x:Name="DocumentView"
BackgroundColor="Silver"
HorizontalOptions="FillAndExpand"

</StackLayout>
</ContentPage>
where:
public class QLDocumentView : View
{
public static readonly BindableProperty FilePathProperty =
BindableProperty.Create(nameof(FilePath), typeof(string), typeof(QLDocumentView), null);
public string FilePath
{

If the application setups the main page like below:
MainPage = new NavigationPage(new QuickLookIOS10TestPage());
it does work on iOS 9.3 but not on iOS 10. If I remove NavigationPage:
MainPage = new QuickLookIOS10TestPage();
it works on both iOS versions.
The code behind for button clicks just sets the FilePath property of the control.
Sample app demonstrating the problem
Xamarin Forms 2.3.2.127
Xamarin Studio 6.1.1 (build 15)
I've faced with the same problem. It looks like something was changed or even broken in QuickLook in iOS10, but the solution is quite simple:
public class PdfViewerControlRenderer : ViewRenderer<PdfViewerControl, UIView>
{
private readonly bool IsOniOS10;
private UIViewController _controller;
private QLPreviewController _qlPreviewController;
public PdfViewerControlRenderer()
{
IsOniOS10 = UIDevice.CurrentDevice.CheckSystemVersion(10, 0);
}
protected override void OnElementChanged(ElementChangedEventArgs<PdfViewerControl> e)
{
if (e.NewElement != null)
{
_controller = new UIViewController();
_qlPreviewController = new QLPreviewController();
//...
// Set QuickLook datasource here
//...
if (!IsOniOS10)
{
_controller.AddChildViewController(_qlPreviewController);
_controller.View.AddSubview(_qlPreviewController.View);
_qlPreviewController.DidMoveToParentViewController(_controller);
}
SetNativeControl(_controller.View);
}
}
public override void LayoutSubviews()
{
base.LayoutSubviews();
_controller.View.Frame = Bounds;
_controller.View.AutoresizingMask = UIViewAutoresizing.FlexibleWidth | UIViewAutoresizing.FlexibleHeight;
_qlPreviewController.View.Frame = Bounds;
if (IsOniOS10)
{
_controller.View.AddSubview(_qlPreviewController.View);
_qlPreviewController.DidMoveToParentViewController(_controller);
}
}
}
Result:
In XNA, i want to manage background sound for every game state. For example; StartMenu music will be playing when option is Start or Playing music will be playing when option is Playing. I arranged code as followed, as you can see i create play and stop method inside all sound class but it's only working while exiting to game.
public abstract class Sound
{
public SoundEffect Item { get; set; }
public Song BgSound { get; set; }
public abstract void LoadContent(ContentManager content);
public abstract void Play();
public abstract void Stop();
}
public class GameSound : Sound
{
public GameSound()
{
BgSound = null;
Item = null;
}
public override void LoadContent(ContentManager content)
{
BgSound = content.Load<Song>("Sounds/BgSound");
MediaPlayer.IsRepeating = true;
}
public override void Play()
{
MediaPlayer.Play(BgSound);
}
public override void Stop()
{
MediaPlayer.Stop();
}
}
public class StartUpSound : Sound
{
public StartUpSound()
{
BgSound = null;
Item = null;
}
public override void LoadContent(ContentManager content)
{
BgSound = content.Load<Song>("Sounds/StartUp");
MediaPlayer.IsRepeating = false;
}
public override void Play()
{
MediaPlayer.Play(BgSound);
}
public override void Stop()
{
MediaPlayer.Stop();
}
}
public class GameBase : Microsoft.Xna.Framework.Game
{
//..
GameSound gameSoundFx = new GameSound();
StartUpSound startUpSoundFx = new StartUpSound();
//..
protected override void LoadContent()
{
spriteBatch = new SpriteBatch(GraphicsDevice);
gameSoundFx.LoadContent(Content);
startUpSoundFx.LoadContent(Content);
}
protected override void Draw(GameTime gameTime)
{
GraphicsDevice.Clear(Color.CornflowerBlue);
spriteBatch.Begin();
if (currentState == GameState.StartMenu)
{
startUpSoundFx.Play();
}
if (currentState == GameState.Playing)
{
startUpSoundFx.Stop();
gameSoundFx.Play();
}
spriteBatch.End();
base.Draw(gameTime);
}
}
Edited
Also i tried again like this but nothing has changed;
if (currentState == GameState.StartMenu)
{
startUpSoundFx.BgSound = Content.Load<Song>("Sounds/StartUp");
MediaPlayer.Play(startUpSoundFx.BgSound);
}
if (currentState == GameState.Playing)
{
MediaPlayer.Stop();
gameSoundFx.BgSound = Content.Load<Song>("Sounds/StartUp");
MediaPlayer.Play(gameSoundFx.BgSound);
}
This has already been answered -
https://gamedev.stackexchange.com/questions/86038/c-how-to-properly-play-background-songs-in-xna
Please review the answer there, here's the example included -
switch (currentGameState)
{
case GameState.MainMenu:
if (musicState == MusicState.Playing && currentGameState != lastGameState)
{
MediaPlayer.Stop();
musicState = MusicState.NotPlaying;
}
if (musicState == MusicState.NotPlaying)
{
MediaPlayer.Play(song_mainTheme);
musicState = MusicState.Playing;
}
break;
case GameState.GamePlaying:
if (musicState == MusicState.Playing && currentGameState != lastGameState)
{
MediaPlayer.Stop();
musicState = MusicState.NotPlaying;
}
if (musicState == MusicState.NotPlaying)
{
MediaPlayer.Play(song_actionTheme);
musicState = MusicState.Playing;
}
break;
}
It shows extending the states to allow for proper use of the Mediaplayer - as stated in the comments of your question.
How to Create Geo fence(Creating and Monitoring Geo fences) on current latitude,longitude.
I am trying multiple example but not create.
Using this code:
public Geofence geofence(float radius, double latitude, double longitude) {
String id = UUID.randomUUID().toString();
return new Geofence.Builder()
.setRequestId(id)
.setTransitionTypes(Geofence.GEOFENCE_TRANSITION_ENTER)
.setCircularRegion(latitude, longitude, radius)
.setExpirationDuration(Geofence.NEVER_EXPIRE)
.build();
}
There's this tutorial from Google, that's very easy to follow:
http://io2015codelabs.appspot.com/codelabs/geofences
There's also a course at Udacity that teaches location services, including geofences:
https://www.udacity.com/course/google-location-services-on-android--ud876-1
Add Google Play Services to Gradle File:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.0.0'
compile 'com.google.android.gms:play-services:7.3.0'
}
Add to Manifest File:
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
Add to Activity's XML Layout file:
<Button
android:id="#+id/add_geofences_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:onClick="addGeofencesButtonHandler"
android:text="Add GeoFences" />
Add to Activity's Java File:
public class MainActivity extends Activity
implements
GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener,
ResultCallback<Status>{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mAddGeofencesButton = (Button) findViewById(R.id.add_geofences_button);
// Empty list for storing geofences.
mGeofenceList = new ArrayList<Geofence>();
// Get the geofences used. Geofence data is hard coded in this sample.
populateGeofenceList();
// Kick off the request to build GoogleApiClient.

// Test
LANDMARKS.put("SFO", new LatLng(37.621313,-122.378955));

for (Geofence geofence : event.getTriggeringGeofences()) {
triggeringIDs.add(geofence.getRequestId());
}
return String.format("%s: %s", transitionString, TextUtils.join(", ", triggeringIDs));
}
private void sendNotification(String notificationDetails) {
// Create an explicit content Intent that starts MainActivity.
Intent notificationIntent = new Intent(getApplicationContext(), MainActivity.class);
// Get a PendingIntent containing the entire back stack.
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
stackBuilder.addParentStack(MainActivity.class).addNextIntent(notificationIntent);
PendingIntent notificationPendingIntent =
stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
// Get a notification builder that's compatible with platform versions >= 4
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
// Define the notification settings.
builder.setColor(Color.RED)
.setContentTitle(notificationDetails)

.setContentIntent(notificationPendingIntent)
.setAutoCancel(true);
// Fire and notify the built Notification.
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

You should probably stick to their tutorial instead of copying and pasting the code to your project :D
