How to lock the screen orientation of the fragment to landscape at runtime

I have an activity whose ist fragment is set to normal potrait orientation but on loading the second fragment, I need to lock the orientation of the second fragment to landscape. Is it possible to do that?

This is my java fragment class

public class DeputationsFragment extends Fragment implements AdapterView.OnItemSelectedListener{
    LinearLayout ll;
    RecyclerView recyclerView;
    SessionManager sessionManager;
    CheckBox checkBox;
    Spinner reportType;
    String[] reportTypes,reportCodes;
    String reportCode;




    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
        return inflater.inflate(R.layout.fragment_deputations, container, false);
    }

    @Override
    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        sessionManager=SessionManager.NewInstance(getActivity());
        ll=(LinearLayout)view.findViewById(R.id.ll1);
        recyclerView=(RecyclerView)view.findViewById(R.id.recyclerView);
        recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
        checkBox=(CheckBox)view.findViewById(R.id.sno);
        reportType=(Spinner)view.findViewById(R.id.spin_report);
        reportType.setOnItemSelectedListener(this);
        if(Constants.isOnline())
        {
            getTypes();
        }

    }

    @Override
    public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
        reportCode=reportCodes[i];
    }

    @Override
    public void onNothingSelected(AdapterView<?> adapterView) {

    }


    private void getTypes()
    {
        AsyncHttpClient client=new AsyncHttpClient();
        String url=getResources().getString(R.string.urlReportType);
        Constants.showProgress(getActivity());
        client.get(url, new TextHttpResponseHandler() {
            @Override
            public void onFailure(int statusCode, Header[] headers, String responseString, Throwable throwable) {

            }

                    Toast.makeText(getActivity(), "Error", Toast.LENGTH_LONG).show();
                    int p2 = responseString.lastIndexOf("<");
                    String r = responseString.substring(p1 + 1, p2);
                    p1 = r.indexOf(">");
                    r = r.substring(p1 + 1, r.length());

Add in manifest android:configChanges="keyboardHidden|orientation"

add in your fragment 

@Override
public void onConfigurationChanged(@NonNull Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    if (getActivity() != null) {
        if (isViewProfileOrNot) {
            if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {
                getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
            } else if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
                getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
            }
        }

    }

}

I have implemented the same functionality myself. My app is locked to Portrait mode for all fragments except one. In order to achieve the correct functionality I use android:screenOrientation="nosensor" for the activity (in the Manifest file) preventing orientation changes due to the user rotating the device.

I also use android:configChanges="keyboardHidden|orientation|screenSize" to prevent the activity to restart when the orientation is changed. Otherwise, it's easy to end up in a loop where the activity restarts, goes into the correct fragment and changes the orientation again, repeat.

In the Fragment's onResume() method I call getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); and in it's onPause() I call getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

Hope this helps you!

this would be the best option then.

@Override
public void setUserVisibleHint(boolean isVisibleToUser) {
super.setUserVisibleHint(isVisibleToUser);
if(isVisibleToUser) {
    Activity a = getActivity();
    if(a != null)     a.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
 }
}

good luck with ur project:)

Override function setUserVisibleHint() in second fragment then use the below code

@Override
public void setUserVisibleHint(boolean isVisibleToUser) {
    super.setUserVisibleHint(isVisibleToUser);
    if(isVisibleToUser) {
        Activity curActivity = getActivity();
        if(curActivity != null){ 
             curActivity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
         }
     }
}

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.

So you need set orientation in onCreateView of each fragment Plse Check below code:

FragmentA 

 public class FragmentA extends Fragment {


        @Override

        public View onCreateView(LayoutInflater inflater,ViewGroup container, Bundle savedInstanceState) {

            View view = inflater.inflate(R.layout.fragment_a, container, false);
            changeFragmentOrientation();


            return view;

        }

    }

public void changeFragmentOrientation(){
getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
}

FragmentB

public class FragmentB extends Fragment {


            @Override

            public View onCreateView(LayoutInflater inflater,ViewGroup container, Bundle savedInstanceState) {

                View view = inflater.inflate(R.layout.fragment_b, container, false);
                changeFragmentOrientation();


                return view;

            }

        }

    public void changeFragmentOrientation(){
    getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
    }

Try this on your onCreate to set Landscape programmatically on your activities or fragments.

Activity

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR);

Fragment

After rootView in your java add this line 

getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
