Screen Orientation

 Android Screen Orientation Example

The screenOrientation is the attribute of activity element. The orientation of android activity can be portrait, landscape, sensor, unspecified etc. You need to define it in the AndroidManifest.xml file.

Syntax:

1. <activity android:name="package_name.Your_ActivityName"  
2.       android:screenOrientation="orirntation_type">  
3. </activity>  

Example:

1. <activity android:name=" example.tranning.com.screenorientation.MainActivity"  
2.      android:screenOrientation="portrait">  
3. </activity>  

1. <activity android:name=".SecondActivity"  
2.      android:screenOrientation="landscape">  
3. </activity>  

The common values for screenOrientation attribute are as follows:

Value	Description
unspecified	It is the default value. In such case, system chooses the orientation.
portrait	taller not wider
landscape	wider not taller
sensor	orientation is determined by the device orientation sensor.

Orientation attribute in activity and provides its orientation. In this example, we provide "portrait" orientation for MainActivity and "landscape" for SecondActivity.
