How to set entire application in portrait mode only?

Question

How do I set it so the application is running in portrait mode only? I want the landscape mode to be disabled while the application is running. How do I do it programmatically?

Answer 1

For any Android version

From XML

You can specify android:screenOrientation="portrait" for each activity in your manifest.xml file. You cannot specify this option on the application tag.

From Java

Other option is to do it programmatically, for example in an Activity base class:

@Override
public void onCreate(Bundle savedInstanceState) {
  setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}

For Android 4+ (API 14+)

Last option is to do it with activity lifecycle listeners which is only available since Android 4.0 (API 14+). Everything happens in a custom Application class:

@Override
public void onCreate() {
    super.onCreate();  
    registerActivityLifecycleCallbacks(new ActivityLifecycleAdapter() {
        @Override
        public void onActivityCreated(Activity a, Bundle savedInstanceState) {
            a.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
        }
    });
}

ActivityLifecycleAdapter is just a helper class you'll need to create which will be an empty implementation of ActivityLifecycleCallbacks (so you don't have to override each and every methods of that interface when you simply need one of them).

Answer 2

Yes you can do this both programmatically and for all your activities making an AbstractActivity that all your activities extends.

public abstract class AbstractActivity extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
    }
}

This abstract activity can also be used for a global menu.

Answer 3

You can do this for your entire application without having to make all your activities extend a common base class.

The trick is first to make sure you include an Application subclass in your project. In its onCreate(), called when your app first starts up, you register an ActivityLifecycleCallbacks object (API level 14+) to receive notifications of activity lifecycle events.

This gives you the opportunity to execute your own code whenever any activity in your app is started (or stopped, or resumed, or whatever). At this point you can call setRequestedOrientation() on the newly created activity.

class MyApp extends Application {

    @Override
    public void onCreate() {
        super.onCreate();  

        // register to be informed of activities starting up
        registerActivityLifecycleCallbacks(new ActivityLifecycleCallbacks() {

            @Override
            public void onActivityCreated(Activity activity, 
                                          Bundle savedInstanceState) {

                // new activity created; force its orientation to portrait
                activity.setRequestedOrientation(
                    ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

            }

            ....

        });

    }
}

Answer 4

You can set this in your manifest file..

android:name=".your launching activity name"
android:screenOrientation="portrait"

and you can also achive the same by writing the code in your class file like:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

Answer 5

Add android:screenOrientation="portrait" to the activity in the AndroidManifest.xml. For example:

<activity android:name=".SomeActivity"
    android:label="@string/app_name"
    android:screenOrientation="portrait">

Answer 6

Use:

android:screenOrientation="portrait" 

Just write this line in your application's manifest file in each activity which you want to show in portrait mode only.

Answer 7

Write this to your manifest file, for every activity:

android:screenOrientation="portrait" 

Answer 8

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


    //setting screen orientation locked so it will be acting as potrait
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LOCKED);
}

Answer 9

As from Android developer guide :

"orientation" The screen orientation has changed — the user has rotated the device. Note: If your application targets API level 13 or higher (as declared by the minSdkVersion and targetSdkVersion attributes), then you should also declare the "screenSize" configuration, because it also changes when a device switches between portrait and landscape orientations.

"screenSize" The current available screen size has changed. This represents a change in the currently available size, relative to the current aspect ratio, so will change when the user switches between landscape and portrait. However, if your application targets API level 12 or lower, then your activity always handles this configuration change itself (this configuration change does not restart your activity, even when running on an Android 3.2 or higher device). Added in API level 13.

So, in the AndroidManifest.xml file, we can put:

<activity
            android:name=".activities.role_activity.GeneralViewPagerActivity"
            android:label="@string/title_activity_general_view_pager"
            android:screenOrientation="portrait"
            android:configChanges="orientation|keyboardHidden|screenSize"
            >
        </activity> 

Answer 10

Adding <preference name="orientation" value="portrait" /> under <widget> in my config.xml worked for me.

(The other solutions either didn't work on my device, were overwritten during building or gave deprecation errors during the build process.)

Answer 11

in Manifest file which activity you want to use in "portrait" you must write these code in Activity tag

  android:screenOrientation="portrait" 

like this

         android:icon="@drawable/icon"
        android:name="com.zemkoapps.hd.wallpaper.AndroidGridLayoutActivity" 
        android:screenOrientation="portrait" >

but if u want screen in landscape use this code like this

android:screenOrientation="landscape"

Answer 12

If anyone was wondering , how you could do this for your entire application without having to make all your activities extend a common base class in Kotlin , see the example below :

class InteractiveStoryApplication: Application() {
override fun onCreate() {
    super.onCreate()
    registerActivityLifecycleCallbacks(object: ActivityLifecycleCallbacks {
        override fun onActivityCreated(activity: Activity?, savedInstanceState: Bundle?) {
            activity?.requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT
        }

        override fun onActivityPaused(activity: Activity?) {
        }

        override fun onActivityResumed(activity: Activity?) {
        }

        override fun onActivityDestroyed(activity: Activity?) {
        }

        override fun onActivitySaveInstanceState(activity: Activity?, outState: Bundle?) {
        }

        override fun onActivityStarted(activity: Activity?) {
        }

        override fun onActivityStopped(activity: Activity?) {
        }
    })
}
}

and then you have to add your common base class in AndroidManifest like so:

<application android:allowBackup="true"
android:name=".InteractiveStoryApplication"

Answer 13

You can do it in two ways .

1. Add android:screenOrientation="portrait" on your manifest file to the corresponding activity
2. Add setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); to your activity in `onCreate() method
