How to set application fragments to portrait mode only?

Question

I have an Android app which has a main activity and 3 Fragments which are tabs. I would like the application to remain in portrait mode at all times but I can't seem to get this working. This is what I have tried, as per another stack overflow post, but I'm not sure what I'm doing wrong....does it need to be different if using fragments?

    <activity
        android:name="com.tutorial.test.activities.act1"
        android:label="@string/app_name" 
        android:screenOrientation="portrait"
        android:configChanges="orientation|keyboardHidden" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

Thank you!!

Edit: The ViewPager is on the FragmentActivity for which I am setting the screenOrientation as above.

Answer 1

Try this..

You can try with programmatically.

After rootView in your java add this line getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

For Ex:

View rootView = inflater.inflate(R.layout.activityxml, container, false);       
getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

And also in your manifest change it android:configChanges="orientation|keyboardHidden" as android:configChanges="keyboardHidden"

<activity
        android:name="com.tutorial.test.activities.act1"
        android:label="@string/app_name" 
        android:screenOrientation="portrait"
        android:configChanges="keyboardHidden" >

Orientation attribute is per activity so you can declare the orientation for only the activity that contains the fragment so that it is in landscape and the rest of the activities will remain as they are.

getActivity().setRequestedOrientation( ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

or you can declare in the manifest

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