I have a FragmentActivity and I want to use a map fragment within it. I'm having a problem getting the support fragment manager to access it.
if (googleMap == null) {
googleMap = ((SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map1)).getMap();
// check if map is created successfully or not
if (googleMap == null) {
Toast.makeText(getApplicationContext(),
"Sorry! unable to create maps", Toast.LENGTH_SHORT)
.show();
}
}
// create marker
MarkerOptions marker = new MarkerOptions().position(
new LatLng(latitude, longitude)).title("Hello Maps ");
CameraPosition cameraPosition = new CameraPosition.Builder()
.target(new LatLng(latitude, longitude)).zoom(15).build();
googleMap.animateCamera(CameraUpdateFactory
.newCameraPosition(cameraPosition));
// adding marker
googleMap.addMarker(marker);

Simply get it like this -
getFragmentManager() // This will also give you the SupportFragmentManager or FragmentManager based on which Fragment class you have extended - android.support.v4.app.Fragment OR android.app.Fragment.
OR
getActivity().getSupportFragmentManager();
in your Fragment's onActivityCreated() method and any method that is being called after onActivityCreated().
do this in your fragment
getActivity().getSupportFragmentManager()
The simple new way of doing it in kotlin
requireActivity().supportFragmentManager
((AppCompatActivity) getActivity()).getSupportFragmentManager()
Some Kotlin code to use supportFragmentManager inside a Fragment.
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
super.onCreateView(inflater, container, savedInstanceState)
val rootView = inflater.inflate(R.layout.fragment_home, container, false)
// ....
if (rootView.home_play_btn != null) {
rootView.home_play_btn.setOnClickListener {
val fragment: BaseFragment = ListFragment.newInstance()
val fragManager: FragmentManager = (activity as AppCompatActivity).supportFragmentManager
fragManager.beginTransaction()
.replace(R.id.content_home_frame, fragment, TAG).commit()
}
in java you can replace with
getChildFragmentManager()
in kotlin, make it simple by
childFragmentManager
hope it help :)
My Parent Activity extends AppCompatActivity so I had to cast my context to AppCompatActivity instead of just Activity.
eg.
FragmentAddProduct fragmentAddProduct = FragmentAddProduct.newInstance();
FragmentTransaction fragmentTransaction = ((AppCompatActivity)mcontext).getSupportFragmentManager().beginTransaction();
if you have this problem and are on api level 21+ do this:
map = ((SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map))
.getMap();
this will get the map when used inside of a fragment.
getFragmentManager()
has been deprecated in favor of getParentFragmentManager()
to make it clear that you want to access the fragment manager of the parent instead of any child fragments.
Simply use getParentFragmentManager()
in Java or parentFragmentManager
in Kotlin.
You can simply access like
Context mContext;
public View onCreateView(LayoutInflater inflater,
@Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
mContext = getActivity();
}
and then use
FragmentManager fm = ((FragmentActivity) mContext)
.getSupportFragmentManager();
Try this:
private SectionsPagerAdapter mSectionsPagerAdapter = new SectionsPagerAdapter(getActivity().getSupportFragmentManager());
You can use childFragmentManager inside Fragments.
getActivity().getFragmentManager()
This worked or me.
Also take a look at here.
You can use getActivity().getSupportFragmentManager()
anytime you want to getSupportFragmentManager.
hierarchy is Activity -> fragment. fragment is not capable of directly calling getSupportFragmentManger but Activity can . Thus, you can use getActivity to call the current activity which the fragment is in and get getSupportFragmentManager()
All you need to do is using
getFragmentManager()
method on your fragment. It will give you the support fragment manager, when you used it while adding this fragment.
getSupportFragmentManager()
used when you are in activity and want to get a fragment but in the fragment you can access
getSupportFragmentManager()
by use another method called getFragmentMangaer()
works the same like getSupportFragmentManager()
and you can use it like you used to:
fragmentTransaction =getFragmentManager().beginTransaction();
The following code does the trick for me
SupportMapFragment mapFragment = ((SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map));
mapFragment.getMapAsync(this);
Kotlin users try this answer
(activity as AppCompatActivity).supportFragmentManager
