Screen Orientation
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:
<activity android:name="package_name.Your_ActivityName"
android:screenOrientation="orirntation_type">
</activity>
android:screenOrientation="orirntation_type">
</activity>
Example:
<activity android:name=" example.javatpoint.com.screenorientation.MainActivity"
android:screenOrientation="portrait">
</activity>
android:screenOrientation="portrait">
</activity>
<activity android:name=".SecondActivity"
android:screenOrientation="landscape">
</activity>
android:screenOrientation="landscape">
</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. |
Android Portrait and Landscape mode screen orientation example
In this example, we will create two activities of different screen orientation. The first activity (MainActivity) will be as "portrait" orientation and second activity (SecondActivity) as "landscape" orientation type.

AndroidManifest.xml
File: AndroidManifest.xml
In AndroidManifest.xml file add the screenOrientation attribute in activity and provides its orientation. In this example, we provide "portrait" orientation for MainActivity and "landscape" for SecondActivity.
package example.javatpoint.com.screenorientation;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
public class SecondActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_second);
}
}
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
public class SecondActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_second);
}
}
Output:
