setting screenOrientation to portrait doesn't work

Question

I want to run my app in portrait mode, I'm aware this isn't best practice but there are reasons to do this. and while I have disabled the rotation it still is able to rotate on some views will it doesn't on others.

I have this part of code in my Android Manifest:

 <activity
        android:name="<name>.app.MainActivity"
        android:label="@string/app_name"
        android:configChanges="keyboardHidden|keyboard|locale|orientation"
        android:screenOrientation="portrait">

I'm using fragments to show different containers depending on user input.

this is the only activity that has fragments. I have tried a few solutions on this site. including setting portrait mode on by code

Answer 1

You can do it something like below.

After rootView in your java add this line

 getActivity().setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);  // programmatically

For example:

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.test.activity"
    android:label="@string/app_name" 
    android:screenOrientation="portrait"
    android:configChanges="keyboardHidden" >
