How to use AutocompleteSupportFragment inside a fragment

Question

I am using places api and dependency

 implementation 'com.google.android.libraries.places:places:1.0.0'

I want to add an AutocompleteSupportFragment in a fragment. Please help me where should I place the code in the fragment. I have tried on these methods

1. onCreate() 2. onCreateView() 3. onViewCreated() 4. onActivityCreated()

But it gives null object reference error. I have tried it with an activity, it works fine.

public class MyActivity extends Fragment implements OnMapReadyCallback{

 AutocompleteSupportFragment autocompleteSupportFragment; public ConsumerBookingMapFragment(){ } @Override public void onCreate(@Nullable Bundle savedInstanceState) { super.onCreate(savedInstanceState); } @Nullable @Override public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { mView = inflater.inflate(R.layout.fragment_consumer_booking_map,container,false); return mView; } @Override public void onViewCreated(View view, @Nullable Bundle savedInstanceState) { super.onViewCreated(view, savedInstanceState); if (savedInstanceState != null) { mLastKnownLocation = savedInstanceState.getParcelable(KEY_LOCATION); mCameraPosition = savedInstanceState.getParcelable(KEY_CAMERA_POSITION); } mFusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(getActivity()); mMapView = mView.findViewById(R.id.map); if(mMapView != null){ mMapView.onCreate(null); mMapView.onResume(); mMapView.getMapAsync(this); } } @Override public void onActivityCreated(@Nullable Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); }

This is my code, guide me where should I initialize the AutocompleteSupportFragment. — Sami Noor Khan

This is a working solution.

 AutocompleteSupportFragment autocompleteFragment = (AutocompleteSupportFragment) getChildFragmentManager().findFragmentById(R.id.autocomplete_fragment);

Use getChildFragmentManager() instead of getSupportFragmentManager()/getFragmentManager()

It is answered in this post...

Google Places API AutocompleteSupportFragment Null pointer Exception

Things to remember..

Make sure you use component in your layout xml file. (Not FrameLayout) Also use the android:name as shown below..

<fragment android:id="@+id/autoCompleteFragment" android:layout_width="match_parent" android:layout_height="match_parent" android:name="com.google.android.libraries.places.widget.AutocompleteSupportFragment" />

And follow the steps in the answer
