Keep your activity in a horizontal or vertical screen

There are two ways to keep your activity in a horizontal or vertical screen, and one is to set it in the activity's Androidmanifest.xml

<ActivityAndroid:name=". Mainactivity "Android:label= "@string/app_name"

<!--Set Horizontal screen vertical screen to portrait-->android:screenorientation= "Landscape" >            <Intent-filter>                <ActionAndroid:name= "Android.intent.action.MAIN" />                <categoryAndroid:name= "Android.intent.category.LAUNCHER" />            </Intent-filter>        </Activity>

Set in the activity code:

// Horizontal Screen         setrequestedorientation (activityinfo.screen_orientation_landscape);         // Vertical Screen // setrequestedorientation (activityinfo.screen_orientation_portrait);
