Interagir avec le bouton d'une autre mise en page dans SupportMapFragment

Question

Je voudrais savoir comment masquer/afficher le FloatingActionButton lorsque vous cliquez sur un marqueur dans la carte.

Voici le code Maps:

public class MapsActivity extends SupportMapFragment implements 
OnMapReadyCallback, GoogleMap.OnMapClickListener, 
GoogleMap.OnMarkerClickListener, GoogleMap.OnInfoWindowClickListener { 

private static final String TAG = "Maps"; 
private GoogleMap mMap; 
private LocationManager locationManager; 
private ArrayList<LatLng> latlngs = new ArrayList<>(); 
private MarkerOptions markerOptions = new MarkerOptions(); 
private Marker markerN; 
private Marker markerO; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    getMapAsync(this); 
} 

@Override 
public void onMapReady(GoogleMap googleMap) { 

    try { 
     Criteria criteria = new Criteria(); 
     locationManager = (LocationManager) 
getActivity().getSystemService(Context.LOCATION_SERVICE); 
     mMap = googleMap; 
     mMap.setOnMapClickListener(this); 
     mMap.setOnMarkerClickListener(this); 
     mMap.getUiSettings().setZoomControlsEnabled(true); 
     mMap.getUiSettings().setMapToolbarEnabled(false); 
     mMap.setMyLocationEnabled(true); 
     Location location = 
locationManager.getLastKnownLocation(locationManager 
       .getBestProvider(criteria, false)); 
     double latitude = location.getLatitude(); 
     double longitude = location.getLongitude(); 
     LatLng sydney = new LatLng(latitude, longitude); 
     mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(sydney, 15.0f)); 
     mMap.setOnInfoWindowClickListener(this); 
    } catch (SecurityException ex) { 
     Log.e(TAG, "Error", ex); 
     requestPermissions(new String[] 
{Manifest.permission.ACCESS_FINE_LOCATION}, 
       1); 
    } catch (Exception e) { 
     System.out.println(e); 
    } 

    try { 
     // Customise the styling of the base map using a JSON object defined 
     // in a raw resource file. 
     boolean success = mMap.setMapStyle(
       MapStyleOptions.loadRawResourceStyle(
         getContext(), R.raw.style_json)); 

     if (!success) { 
      Log.e("MapsActivityRaw", "Style parsing failed."); 
     } 
    } catch (Resources.NotFoundException e) { 
     Log.e("MapsActivityRaw", "Can't find style.", e); 
    } 

    latlngs.add(new LatLng(-22.978608, -49.869901)); 
    for (LatLng point : latlngs) { 
     markerOptions.position(point); 
     markerOptions.title("Local"); 
     markerOptions.snippet("Info"); 
     markerO = mMap.addMarker(markerOptions); 
    } 
} 

@Override 
public void onMapClick(LatLng latLng) { 
    mMap.clear(); 
    markerOptions.position(latLng); 

    markerOptions.title("Deseja cadastrar este local?"); 
    markerOptions.snippet("Pressione aqui"); 
    markerN = mMap.addMarker(markerOptions); 
    mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(latLng, 17.0f)); 
    Toast.makeText(getContext(), "Coord: " + latLng.toString(), 
Toast.LENGTH_LONG).show(); 
} 

@Override 
public void onRequestPermissionsResult(int requestCode, String 
permissions[], int[] grantResults) { 
    switch (requestCode) { 
     case 1: { 
      // If request is cancelled, the result arrays are empty. 
      if (grantResults.length > 0 
        && grantResults[0] == PackageManager.PERMISSION_GRANTED) 
{ 

      } else { 
       // permission denied, boo! Disable the 
       // functionality that depends on this permission. 
      } 
      return; 
     } 
     // other 'case' lines to check for other 
     // permissions this app might request 
    } 
} 

@Override 
public void onInfoWindowClick(Marker marker) { 
    if (marker.equals(markerN)) { 
     Toast.makeText(getContext(), "Clique 2", Toast.LENGTH_LONG).show(); 
    } else { 

    } 
} 

@Override 
public boolean onMarkerClick(Marker marker) { 
    if (marker.equals(markerN)) { 
     Toast.makeText(getContext(), "Clique 1", Toast.LENGTH_LONG).show(); 
    } else { 
     Toast.makeText(getContext(), "Abrir Informações", 
Toast.LENGTH_LONG).show(); 
    } 
    return false; 
} 
} 

Et c'est le XML que je veux interagir:

<?xml version="1.0" encoding="utf-8"?> 
<android.support.design.widget.CoordinatorLayout 
xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:app="http://schemas.android.com/apk/res-auto" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
tools:context="com.example.alan.unigeo.MainActivity"> 

<android.support.design.widget.AppBarLayout 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:theme="@style/AppTheme.AppBarOverlay"> 

    <android.support.v7.widget.Toolbar 
     android:id="@+id/toolbar" 
     android:layout_width="match_parent" 
     android:layout_height="?android:attr/actionBarSize" 
     android:background="?attr/colorPrimary" 
     app:popupTheme="@style/AppTheme.PopupOverlay" /> 

</android.support.design.widget.AppBarLayout> 

<include layout="@layout/content_main" /> 

<android.support.design.widget.FloatingActionButton 
    android:id="@+id/fab" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_gravity="bottom|end" 
    android:layout_margin="@dimen/fab_margin" 
    app:srcCompat="@android:drawable/ic_dialog_email" /> 

</android.support.design.widget.CoordinatorLayout> 

J'ai tryed la recherche d'exemples aussi bien cette situation, mais a échoué. Le Maps est à l'intérieur d'un fragment d'une mise en page, et le FloatingActionButton est placé dans une autre disposition "au-dessus" de la précédente. Je ne sais pas si j'ai besoin de montrer un autre code pour vous aider, si nécessaire, demandez-le.

Answer 1

J'ai la fonctionnalité dans mon programme.

Si vous ne voulez pas le montrer, utilisez ce code:

@Override 
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) { 
    super.onViewCreated(view, savedInstanceState); 
    ((FloatingActionButton) getView().getRootView().findViewById(R.id.fab)).hide(); 
} 

@Override 
public void onDestroyView() { 
    super.onDestroyView(); 
    ((FloatingActionButton) getView().getRootView().findViewById(R.id.fab)).show(); 
} 

Si vous voulez montrer, juste passer la .show() et .hide().
