The Activity flag ScreenOrientation.Portrait does not exist

Question

I added the following code to the Activity flag and it says that it does not exist.

    ScreenOrientation = ScreenOrientation.Portrait

"ScreenOrientation.Portrait" is the only part that it says does not exist. Do I have to add another reference? Do i have to define it somewhere else? Other forums just said to add the code above. Thank you to those that took the time.

Answer 1

Using the following Activity flag you can force Portrait orientation for the activity:

[Activity (ScreenOrientation = Android.Content.PM.ScreenOrientation.Portrait)]          
public class YourActivity

Answer 2

If you want to change activity layout in code, use this:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

Answer 3

The activity's syntax in the androidManifest.xml actually looks like this:

 android:screenOrientation=[
          "unspecified" | "behind" |
          "landscape" | "portrait" |
          "reverseLandscape" | "reversePortrait" |
          "sensorLandscape" | "sensorPortrait" |
          "userLandscape" | "userPortrait" |
          "sensor" | "fullSensor" | "nosensor" |
          "user" | "fullUser" | "locked"]

as it is described at android developers' manifest/activity element: http://developer.android.com/guide/topics/manifest/activity-element.html

To achieve this using xamaring (where you shouldn't edit your androidManifest.xml), you need to add a custom attribute to your class's declaration, to notify the compiler to generate the proper attributes for the <activity .../> tag:

[Activity (Label="MyActivityName", 
    ScreenOrientation = Android.Content.PM.ScreenOrientation.Portrait)]
public class MyActivity : Activity
