Cannot resolve method 'getSupportFragmentManager ( )' inside Fragment

Question

I found the message Cannot resolve method 'getSupportFragmentManager ( )' I want to fragment as activity. because I want to use Maps on the tabs swipe.

public class PETAcikarangsukatani extends Fragment {
Context context;

private static final LatLng SUKATANI = new LatLng(-6.171327, 107.178108);
private static final LatLng WRPOJOK = new LatLng(-6.222411, 107.162158);
private static final LatLng PILAR = new LatLng(-6.257033, 107.156472);
private static final LatLng CIKARANG = new LatLng(-6.256073, 107.143984);


GoogleMap googleMap;
final String TAG = "PathGoogleMapActivity";

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

    View rootView = inflater.inflate(R.layout.activity_path_google_map, container, false);
    context = rootView.getContext();

    SupportMapFragment fm = (SupportMapFragment)getSupportFragmentManager()
            .findFragmentById(R.id.map);
    googleMap = fm.getMap();

Answer 1

Inside a Fragment subclass you have to use getFragmentManager in place of getSupportFragmentManager. You will get the support one if the import are from the support library.

Answer 2

For my case, I made sure that Fragment class is imported from

android.support.v4.app.Fragment

Not from

android.app.Fragment

Then I have used

getActivity().getSupportFragmentManager();

And now its working. If I use activity instance which I got in onAttach() is not working also.

Answer 3

Extends FragmentActivity instead of Activity

Answer 4

Use getActivity().getSupportFragmentManager()

Answer 5

Replace getSupportFragmentManager() with getFragmentManager() if you are working in api 21. OR If your app supports versions of Android older than 3.0, be sure you've set up your Android project with the support library as described in Setting Up a Project to Use a Library and use getSupportFragmentManager() this time.

Answer 6

Also you can use AppCompatActivity instead of Activity.
Then getSupportFragmentManager() will work.
And also not forget to make your App theme extend AppCompat theme in this case

Answer 7

As per the documentation, getSupportFragmentManager() is present only inside AppCompatActivity class. It is not present inside Activity class. So make sure your class extends AppCompatActivity class.

public class MainActivity extends AppCompatActivity {
}

Answer 8

getSupportFragmentManager() is not part of Fragment, so you cannot get it here that way. You can get it from parent Activity (so in onAttach() the earliest) using normal

activity.getSupportFragmentManager();

or you can try getChildFragmentManager(), which is in scope of Fragment, but requires API17+

Answer 9

getFragmentManager()

just try this.it worked for my case

Answer 10

you should use

getActivity.getSupportFragmentManager() like
//in my fragment 
SupportMapFragment fm = (SupportMapFragment)    
getActivity().getSupportFragmentManager().findFragmentById(R.id.map);

I have also this issues but resolved after adding getActivity() before getSupportFragmentManager.

Answer 11

If you're getting "Cannot resolve method getSupportFragmentManager()", try using

this.getSupportFragmentManager()

It works for me when dealing with DialogFragments in android

Answer 12

If you're instantiating an android.support.v4.app.Fragment class, the you have to call getActivity().getSupportFragmentManager() to get rid of the cannot-resolve problem. However the official Android docs on Fragment by Google tends to over look this simple problem and they still document it without the getActivity() prefix.

Answer 13

For me I made sure to import v4 like this:

import android.support.v4.app.DialogFragment;

Then used:

getActivity().getFragmentManager()
