Xamarin.Forms 强迫横竖屏

只要在MainActivity中设置

this.RequestedOrientation = Android.Content.PM.ScreenOrientation.Portrait;//竖屏，禁止横屏

this.RequestedOrientation = Android.Content.PM.ScreenOrientation.Nosensor;//横屏，禁止竖屏
---------------------

Android:

 1  public void ForceLandscape()
 2         {
 3             GetActivity().RequestedOrientation = ScreenOrientation.Landscape;
 4         }
 5 
 6 
 7         public void ForcePortrait()
 8         {
 9             GetActivity().RequestedOrientation = ScreenOrientation.Portrait;
10         }
11 
12  
13 
14         public Activity GetActivity()
15         {
16             var activity = (Activity)Forms.Context;
17             return activity;
18         }

 

 

IOS:

       

 1  public void ForceLandscape()
 2         {
 3             UIDevice.CurrentDevice.SetValueForKey(new NSNumber((int)UIInterfaceOrientation.LandscapeLeft), new NSString("orientation"));
 4         }
 5 
 6 
 7         public void ForcePortrait()
 8         {
 9             UIDevice.CurrentDevice.SetValueForKey(new NSNumber((int)UIInterfaceOrientation.Portrait), new NSString("orientation"));
10         }
