How to Disable landscape mode in Android?

Question

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

Answer 1

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>

Answer 2

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......
}

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!

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>

Answer 5

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>   

Answer 6

Use this in onCreate() of the Activity

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
