MapFragment in Fragment, alternatives?

Question

I need your help... I work on it until 3 days. My app is working with fragments. One of these fragments has to display a map from the Google Maps V2 api for Android.

Answer 1

As described here

To display MapFragment inside the fragment(NestedFragment): At this point I believe you have

1. added necessary permission on manifest
2. added google play service as a lib project
3. api key in manifest file. 4.

where.xml

class:

 public class WhereFragment extends SupportMapFragment {

    @Override
     public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
     {
      super.onCreateView(inflater, container, savedInstanceState);
      View root = inflater.inflate(R.layout.where, null, false); 
      initilizeMap();
      return root;
     }

    private void initilizeMap()
     {
      mSupportMapFragment = (SupportMapFragment) getFragmentManager().findFragmentById(R.id.mapwhere);
      if (mSupportMapFragment == null) {
       FragmentManager fragmentManager = getFragmentManager();
       FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
       mSupportMapFragment = SupportMapFragment.newInstance();
       fragmentTransaction.replace(R.id.mapwhere, mSupportMapFragment).commit();
         }
      if (mSupportMapFragment != null)
      {
       googleMap = mSupportMapFragment.getMap();
       if (googleMap != null)
        googleMap.setOnMapClickListener(new OnMapClickListener()
        {
         @Override
         public void onMapClick(LatLng point)
         {
          //TODO: your onclick stuffs
         }
        });
      }
     }
    }

Documentation:

Nested Fragments You can now embed fragments inside fragments. This is useful for a variety of situations in which you want to place dynamic and re-usable UI components into a UI component that is itself dynamic and re-usable. For example, if you use ViewPager to create fragments that swipe left and right and consume a majority of the screen space, you can now insert fragments into each fragment page.

To nest a fragment, simply call getChildFragmentManager() on the Fragment in which you want to add a fragment. This returns a FragmentManager that you can use like you normally do from the top-level activity to create fragment transactions. For example, here’s some code that adds a fragment from within an existing Fragment class:

Fragment videoFragment = new VideoPlayerFragment(); FragmentTransaction transaction = getChildFragmentManager().beginTransaction(); transaction.add(R.id.video_fragment, videoFragment).commit(); From within a nested fragment, you can get a reference to the parent fragment by calling getParentFragment().

The Android Support Library also now supports nested fragments, so you can implement nested fragment designs on Android 1.6 and higher.

Note: You cannot inflate a layout into a fragment when that layout includes a . Nested fragments are only supported when added to a fragment dynamically.
