Locking Screen Orientation
If you want to lock the screen orientation change of any screen (activity) of your android application you just need to set the
android:screenOrientation property of an
<activity> within the AndroidManifest.xml:
<activity android:name="com.techblogon.screenorientationexample.MainActivity" android:screenOrientation="portrait" android:label="@string/app_name" > <!-- ... --> </activity>
Now that activity is forced to always be displayed in “portrait” mode.
