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();
getSupportFragmentManager and getChildFragmentManager FragmentManager is class provided by the framework which is used to create transactions for adding, removing or replacing fragments. getSupportFragmentManager is associated with Activity consider it as a FragmentManager for your Activity .
Basically, the difference is that Fragment's now have their own internal FragmentManager that can handle Fragments.
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.
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.
Extends FragmentActivity instead of Activity
Use getActivity().getSupportFragmentManager()
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.
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
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 {
}
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+
getFragmentManager()
just try this.it worked for my case
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
.
If you're getting "Cannot resolve method getSupportFragmentManager()", try using
this.getSupportFragmentManager()
It works for me when dealing with DialogFragments in android
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.
For me I made sure to import v4 like this:
import android.support.v4.app.DialogFragment;
Then used:
getActivity().getFragmentManager()
