App/activity/screen Orientation

Test the Android screen orientation of the small demo

1, first we create a new file under Values Arrays.xml (used to display in the drop-down list)

<?xml version= "1.0" encoding= "Utf-8"?><resources>     <!--used in App/screen Orientation    -- <string-array name= "screen_orientations"        <item>UNSPECIFIED</item>        <item>landscape </item>        <item>PORTRAIT</item>        <item>USER</item>        <item>behind </item>        <item>SENSOR</item>        <item>NOSENSOR</item>        <item>sensor _landscape</item>        <item>SENSOR_PORTRAIT</item>        <item>reverse_landscape</ item>        <item>REVERSE_PORTRAIT</item>        <item>FULL_SENSOR</item>    </ String-array></resources>

2. We define the corresponding array in the code

Final Static int New int [] {        activityinfo.screen_orientation_unspecified,        Activityinfo.screen_orientation_landscape,        Activityinfo.screen_orientation_portrait,        activityinfo.screen_orientation_user,        ActivityInfo.SCREEN_ Orientation_behind,        activityinfo.screen_orientation_sensor,        activityinfo.screen_orientation_nosensor ,        Activityinfo.screen_orientation_sensor_landscape,        activityinfo.screen_orientation_sensor_portrait,        Activityinfo.screen_orientation_reverse_landscape,        Activityinfo.screen_orientation_reverse_portrait,        activityinfo.screen_orientation_full_sensor,    };

3. Handling User Selection

@Overrideprotected voidonCreate (Bundle savedinstancestate) {Super. OnCreate (savedinstancestate);                Setcontentview (r.layout.app_activity_screen_orientation); Morientation=(Spinner) Findviewbyid (r.id.app_activity_screen_orientation); Arrayadapter<CharSequence> adapter =Arrayadapter.createfromresource ( This, R.array.screen_orientations, Android.        R.layout.simple_spinner_item); Adapter.setdropdownviewresource (Android.        R.layout.simple_spinner_dropdown_item);        Morientation.setadapter (adapter); Morientation.setonitemselectedlistener (NewOnitemselectedlistener () { Public voidonitemselected (Adapterview<?> Parent, view view,intPositionLongID) {setrequestedorientation (morientationvalues[position]); }                     Public voidOnnothingselected (adapterview<?>parent)                    {setrequestedorientation (activityinfo.screen_orientation_unspecified);    }                }); }
