How to implement Navigation Drawer with Map in a Fragment

I also had this problem!

Here's how I did it:

Activity:

 public class MapsActivity extends AppCompatActivity  {


        private DrawerLayout mDrawerLayout;
        private ListView mListDrawer;
        private ActionBarDrawerToggle mToggle;


        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

            setContentView(R.layout.activity);
            mDrawerLayout = DrawerLayout.class.cast(findViewById(R.id.mDrawerLayout));
            mListDrawer = ListView.class.cast(findViewById(R.id.mListDrawer));


             mToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.title_menu_open, R.string.title_menu_close)
                {
                    @Override
                    public void onDrawerClosed(View drawerView) {
                        super.onDrawerClosed(drawerView);
                        getSupportActionBar().setTitle(R.string.title_menu_open);
                    }
                    @Override
                    public void onDrawerOpened(View drawerView) {
                        super.onDrawerOpened(drawerView);
                        getSupportActionBar().setTitle(R.string.title_menu_close);
                    }
                };

                mDrawerLayout.setDrawerListener(mToggle);
                getSupportActionBar().setDisplayHomeAsUpEnabled(true);
                getSupportActionBar().setHomeButtonEnabled(true);

                openFragment(new MapFragment());
        }

        @Override
        protected void onPostCreate(Bundle savedInstanceState) {
            super.onPostCreate(savedInstanceState);
            mToggle.syncState();
        }

        @Override
        public void onConfigurationChanged(Configuration newConfig) {
            super.onConfigurationChanged(newConfig);
            mToggle.onConfigurationChanged(newConfig);
        }


        @Override
        public boolean onCreateOptionsMenu(Menu menu) {
            return false;
        }

        @Override
        public boolean onOptionsItemSelected(MenuItem item) {
            if (mToggle.onOptionsItemSelected(item)) {
                return true;
            }
            return super.onOptionsItemSelected(item);
        }
        @Override
        protected void onResume() {
            super.onResume();
        }


        public void openFragment(final Fragment fragment){
            if(null == fragment) return;
            final FragmentManager mManager =  getFragmentManager();
            if(mDrawerLayout != null){
                mDrawerLayout.closeDrawers();
            }
            if(null != mManager)
            {
                FrameLayout.class.cast(findViewById(R.id.mContent)).removeAllViewsInLayout();
                mManager.beginTransaction().replace(R.id.mContent, fragment).commit();
            }
        }


    }

Fragment:

public class MapFragment extends Fragment
 {


    MapView mMapView;

    GoogleMap mMap;



    @Override
    public View onCreateView(final LayoutInflater inflater, ViewGroup container, final Bundle savedInstanceState) {
        final View view = inflater.inflate(R.layout.activity_maps, container, false);
        mMapView = MapView.class.cast(view.findViewById(R.id.mapView));
        mMapView.onCreate(savedInstanceState);

        if (mMapView != null) {
            mMap = mMapView.getMap();
            mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
            mMap.getUiSettings().setAllGesturesEnabled(true);
            mMap.getUiSettings().setCompassEnabled(true);
            mMap.getUiSettings().setMyLocationButtonEnabled(true);

        }
        return view;
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        mMapView.onDestroy();
    }

    @Override
    public void onResume() {
        super.onResume();
        mMapView.onResume();
    }

    @Override
    public void onLowMemory() {
        super.onLowMemory();
        mMapView.onLowMemory();
    }
}
