API Usage
Call CrossDeviceOrientation.Current
from any project or PCL to gain access to APIs.
/// <summary>
/// Gets current device orientation
/// </summary>
DeviceOrientations CurrentOrientation { get; }
When device orientation is changed you can register for an event to fire:
/// <summary>
/// Event handler when orientation changes
/// </summary>
event OrientationChangedEventHandler OrientationChanged;
You will get a OrientationChangedEventArgs
with the orientation type:
public class OrientationChangedEventArgs : EventArgs
{
public DeviceOrientations Orientation { get; set; }
}
public delegate void OrientationChangedEventHandler(object sender, OrientationChangedEventArgs e);
The DeviceOrientations enumeration has these members.
Member | Value | Description |
---|---|---|
Undefined | 0 | No display orientation is specified. |
Landscape | 1 | Specifies that the monitor is oriented in landscape mode where the width of the display viewing area is greater than the height. |
Portrait | 2 | Specifies that the monitor rotated 90 degrees in the clockwise direction to orient the display in portrait mode where the height of the display viewing area is greater than the width. |
LandscapeFlipped | 4 | Specifies that the monitor rotated another 90 degrees in the clockwise direction (to equal 180 degrees) to orient the display in landscape mode where the width of the display viewing area is greater than the height. This landscape mode is flipped 180 degrees from the Landscape mode. |
PortraitFlipped | 8 | Specifies that the monitor rotated another 90 degrees in the clockwise direction (to equal 270 degrees) to orient the display in portrait mode where the height of the display viewing area is greater than the width. This portrait mode is flipped 180 degrees from the Portrait mode. |
Call LockOrientation
for set orientation and lock with disabling device auto-rotation:
/// <summary>
/// Lock orientation in the specified position
/// </summary>
/// <param name="orientation">Position for lock.</param>
void LockOrientation(DeviceOrientations orientation);
For disable the lock, call UnlockOrientation
method:
/// <summary>
/// Unlock orientation
/// </summary>
void UnlockOrientation();
iOS Specific Support
Add this code for your ViewController where you want locking orientation:
public override bool ShouldAutorotate()
{
// set plugin for handle of this method
return DeviceOrientationImplementation.ShouldAutorotate;
}
public override UIInterfaceOrientationMask GetSupportedInterfaceOrientations()
{
// allow all orientations
return UIInterfaceOrientationMask.AllButUpsideDown;
}
In your Info.plist
need set all device orientations.
Xamarin.Forms iOS
If you want to lock orientation for the entire iOS application.
Add this code in your AppDelegate.cs
:
[Export("application:supportedInterfaceOrientationsForWindow:")]
public UIInterfaceOrientationMask GetSupportedInterfaceOrientations(UIApplication application, IntPtr forWindow)
{
return DeviceOrientationImplementation.SupportedInterfaceOrientations;
}
Note: In this case, to lock/unlock orientation on the one screen, you must use the LockOrientation
/UnlockOrientation
methods.
Xamarin.Forms Android
In your MainActivity.cs
, add overriding for changing orientation as here:
public override void OnConfigurationChanged(Configuration newConfig)
{
base.OnConfigurationChanged(newConfig);
DeviceOrientationImplementation.NotifyOrientationChange(newConfig.Orientation);
}
Note: This solution has only two state Portrait and Landscape.
