Last post show a example of DialogFragment, to create dialog view in onCreateView(). This example show how to create Dialog using AlertDialog.Builder() in onCreateDialog().
This example modify from last example of "Create DialogFragment with AlertDialog.Builder", to implement interactive DialogFragment. Something sent from main activity to DialogFragment, and something editable in DialogFragment, and something sent from DialogFragment back to main activity.
Example modify from last example "Detect user click on InfoWindow, by implementing GoogleMap.OnInfoWindowClickListener()", to open DialogFragment with StreetViewPanoramaView when user click on InfoWindow.
public class MapsActivity extends AppCompatActivity implements OnMapReadyCallback, GoogleMap.OnMapClickListener, GoogleMap.OnMapLongClickListener, GoogleMap.OnMarkerDragListener, GoogleMap.InfoWindowAdapter {
private GoogleMap mMap;
@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_maps); // Obtain the SupportMapFragment and get notified when the map is ready to be used. SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager() .findFragmentById(R.id.map); mapFragment.getMapAsync(this);
}
/** * Manipulates the map once available. * This callback is triggered when the map is ready to be used. * This is where we can add markers or lines, add listeners or move the camera. In this case, * we just add a marker near Sydney, Australia. * If Google Play services is not installed on the device, the user will be prompted to install * it inside the SupportMapFragment. This method will only be triggered once the user has * installed Google Play services and returned to the app. */ @Override public void onMapReady(GoogleMap googleMap) { mMap = googleMap; mMap.setOnMapClickListener(this); mMap.setOnMapLongClickListener(this); mMap.setOnMarkerDragListener(this); mMap.setInfoWindowAdapter(this); mMap.setOnInfoWindowClickListener(MyOnInfoWindowClickListener); }
