[android] How to Disable landscape mode in Android?

How can I disable landscape mode for some of the views in my Android app?

You must set the orientation of each activity.

<activity
                android:name="com.example.SplashScreen2"
                android:label="@string/app_name"
                android:screenOrientation="portrait"
                android:theme="@android:style/Theme.Black.NoTitleBar" >
            </activity>
            <activity
                android:name="com.example.Registration"
                android:label="@string/app_name"
                android:screenOrientation="portrait"
                android:theme="@android:style/Theme.Black.NoTitleBar" >
            </activity>
            <activity
                android:name="com.example.Verification"
                android:label="@string/app_name"
                android:screenOrientation="portrait"
                android:theme="@android:style/Theme.Black.NoTitleBar" >
            </activity>
            <activity
                android:name="com.example.WelcomeAlmostDone"
                android:label="@string/app_name"
                android:screenOrientation="portrait"
                android:theme="@android:style/Theme.Black.NoTitleBar" >
            </activity>
            <activity
                android:name="com.example.PasswordRegistration"
                android:label="@string/app_name"
                android:screenOrientation="portrait"
                android:theme="@android:style/Theme.Black.NoTitleBar" >
            </activity>

Put it into your manifest.

<activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:screenOrientation="sensorPortrait" />

The orientation will be portrait, but if user's phone is upside down, it show the correct way as well. (So your screen will rotate 180 degrees).

The system ignores this attribute if the activity is running in multi-window mode.

Add this android:screenOrientation="portrait" in your manifest file where you declare your activity like this

<activity android:name=".yourActivity"
    ....
    android:screenOrientation="portrait" />

If you want to do using java code try

setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 

before you call setContentView method for your activity in onCreate().

Hope this help and easily understandable for all...

If you want user-settings,

then I'd recommend setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

You can change the settings from a settings menu.

I require this because my timers must correspond to what's on the screen, and rotating the screen will destroy the current activity.

In kotlin same can be programatically achieved using below

requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT

It worked for me, Try to add this code in AndroidManifest file

<application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:screenOrientation="portrait"
        android:theme="@style/AppTheme">
        ....
        ....
        </application>

Add android:screenOrientation="portrait" in AndroidManifest.xml file.

For example :

<activity android:name=".MapScreen" 
 android:screenOrientation="portrait"></activity>

If you want to disable Landscape mode for your android app ( or a single activity) all you need to do is add,

android:screenOrientation="portrait" to the activity tag in AndroidManifest.xml file.

Like:

<activity android:name="YourActivityName" 
    android:icon="@drawable/ic_launcher" 
    android:label="Your App Name" 
    android:screenOrientation="portrait">

Another Way , Programmatic Approach.

If you want to do this programatically ie. using Java code. You can do so by adding the below code in the Java class of the activity that you don't want to be displayed in landscape mode.

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

I hope it helps you .For more details you can visit here enter link description here

In the <apphome>/platform/android directory created AndroidManifest.xml (copying it from the generated one). Then add android:screenOrientation="portrait" to ALL of the activity elements.

if your activity related to the first device orientation state,get the current device orientation in the onCreate method and then fix it forever:

        int deviceRotation = ((WindowManager) getBaseContext().getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay().getOrientation();

        if(deviceRotation == Surface.ROTATION_0) {
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
        }
        else if(deviceRotation == Surface.ROTATION_180)
        {
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT);
        }
        else if(deviceRotation == Surface.ROTATION_90)
        {
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
        }
        else if(deviceRotation == Surface.ROTATION_270)
        {
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE);
        }

How to change orientation in some of the view

Instead of locking orientation of entire activity you can use this class to dynamically lock orientation from any of your view pragmatically:-

Make your view Landscape

OrientationUtils.lockOrientationLandscape(mActivity);

Make your view Portrait

OrientationUtils.lockOrientationPortrait(mActivity);

Unlock Orientation

OrientationUtils.unlockOrientation(mActivity);

Orientation Util Class

import android.app.Activity;
import android.content.Context;
import android.content.pm.ActivityInfo;
import android.content.res.Configuration;
import android.os.Build;
import android.view.Surface;
import android.view.WindowManager;

/*  * This class is used to lock orientation of android app in nay android devices 
 */

public class OrientationUtils {
    private OrientationUtils() {
    }

    /** Locks the device window in landscape mode. */
    public static void lockOrientationLandscape(Activity activity) {
        activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE);
    }

    /** Locks the device window in portrait mode. */
    public static void lockOrientationPortrait(Activity activity) {
        activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
    }

    /** Locks the device window in actual screen mode. */
    public static void lockOrientation(Activity activity) {
        final int orientation = activity.getResources().getConfiguration().orientation;
        final int rotation = ((WindowManager) activity.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay()
                .getRotation();

        // Copied from Android docs, since we don't have these values in Froyo
        // 2.2
        int SCREEN_ORIENTATION_REVERSE_LANDSCAPE = 8;
        int SCREEN_ORIENTATION_REVERSE_PORTRAIT = 9;

        // Build.VERSION.SDK_INT <= Build.VERSION_CODES.FROYO
        if (!(Build.VERSION.SDK_INT <= Build.VERSION_CODES.FROYO)) {
            SCREEN_ORIENTATION_REVERSE_LANDSCAPE = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE;
            SCREEN_ORIENTATION_REVERSE_PORTRAIT = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT;
        }

        if (rotation == Surface.ROTATION_0 || rotation == Surface.ROTATION_90) {
            if (orientation == Configuration.ORIENTATION_PORTRAIT) {
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
            } else if (orientation == Configuration.ORIENTATION_LANDSCAPE) {
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
            }
        } else if (rotation == Surface.ROTATION_180 || rotation == Surface.ROTATION_270) {
            if (orientation == Configuration.ORIENTATION_PORTRAIT) {
                activity.setRequestedOrientation(SCREEN_ORIENTATION_REVERSE_PORTRAIT);
            } else if (orientation == Configuration.ORIENTATION_LANDSCAPE) {
                activity.setRequestedOrientation(SCREEN_ORIENTATION_REVERSE_LANDSCAPE);
            }
        }
    }

    /** Unlocks the device window in user defined screen mode. */
    public static void unlockOrientation(Activity activity) {
        activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_USER);
    }

}

Add below commend on your project,

npm install

npm i react-native-orientation-locker

then you use manifest class like, React_Native (Your Project Folder)/ android/app/src/main/AndroidManifest.xml

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>

<application
  android:name=".MainApplication"
  android:label="@string/app_name"
  android:icon="@mipmap/ic_launcher"
  android:allowBackup="false"
  android:theme="@style/AppTheme">
  <activity
    android:name=".MainActivity"
    android:label="@string/app_name"
    android:screenOrientation="landscape"
    android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
    android:windowSoftInputMode="adjustResize">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
  </activity>
  <activity android:name="com.facebook.react.devsupport.DevSettingsActivity" />
</application>

Thank You!

use

android:configChanges="keyboardHidden|orientation"
android:screenOrientation="portrait" 

Add android:screenOrientation="portrait" to the activity you want to disable landscape mode.

add class inside oncreate() method

 setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

Either in manifest class.

<activity android:name=".yourActivity"
    ....
    android:screenOrientation="portrait" />

or programmatically

setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 

Note : you should call this before setContentView method for your activity in onCreate().

add this in your manifest android:screenOrientation="portrait" if you want to apply mode for specific activity define this in your desired activity tag. or define in application tag for whole app. like

<application
....
android:screenOrientation="portrait"
</application>

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.

And do not forget to add app:name=".MyApp" in your manifest file.

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);
            }
            ....
        });
    }
}

If you are using Xamarin C# some of these solutions will not work. Here is the solution I found to work.

[Activity(MainLauncher = true, Icon = "@drawable/icon", ScreenOrientation = ScreenOrientation.Portrait)]

Above the class works well, similar to the other solutions, also not globally applicable and needs to be placed in each activity header.

If you don't want to go through the hassle of adding orientation in each manifest entry of activity better, create a BaseActivity class (inherits 'Activity' or 'AppCompatActivity') which will be inherited by every activity of your application instead of 'Activity' or 'AppCompatActivity' and just add the following piece of code in your BaseActivity:

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
    // rest of your code......
}

Use this in onCreate() of the Activity

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

In hopes to help someone else, the following attribute on the ACTIVITY in AndroidManifest.xml is all you need:

android:configChanges="orientation"

So, full activity node:

<activity android:name="Activity1" 
    android:icon="@drawable/icon" 
    android:label="App Name" 
    android:configChanges="orientation">

A lot of the answers here are suggesting to use "portrait" in your AndroidManifest.xml file. This might seem like a good solution - but as noted in the documentation, you are singling out devices that may only have landscape. You are also forcing certain devices (that work best in landscape) to go into portrait, not getting the proper orientation.

My suggestion is to use "nosensor" instead. This will leave the device to use its default preferred orientation, will not block any purchases/downloads on Google Play, and will ensure the sensor doesn't mess up your (NDK, in my case) game.

 <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="in.co.nurture.bajajfinserv">
    <uses-permission android:name="android.permission.INTERNET"></uses-permission>


    <application

        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity" android:screenOrientation="portrait">

            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

we can restrict the Activity in portrait or landscape mode by using the attribute or android:screenOrientation.

if we have more than one activity in my program then you have freedom to restrict any one of activity in any one the mode and it never effect the others which you don't want.

You should change android:screenOrientation="sensorPortrait" in AndroidManifest.xml

<android . . . >
    . . .
    <manifest . . . >
        . . .
        <application>
            <activity android:name=".MyActivity" 
                android:screenOrientation="portrait" 
                android:configChanges="keyboardHidden|orientation">
            </activity>
        </application>
    </manifest>
</android>

I was not aware of the AndroidManifest.xml file switch until reading this post, so in my apps I have used this instead:

setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);     //  Fixed Portrait orientation

Just add Like this Line in Your Manifest

android:screenOrientation="portrait"

<manifest
    package="com.example.speedtest"
    android:versionCode="1"
    android:versionName="1.0" >

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >


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

    </application>

</manifest>   

Just add this attribute in your activity tag.

 android:screenOrientation="portrait"

You can force your particular activity to always remain in portrait mode by writing this in your manifest.xml

 <activity android:name=".MainActivity"
        android:screenOrientation="portrait"></activity>

You can also force your activity to remain in postrait mode by writing following line in your activity's onCreate() method

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.your_layout);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

}
