I've done current location show on google map, but I want to fix marker in center on the map when selected "autoPlace city" and then this location is shown on a google map.
我的代码如下：
public class PostAdsFragmentFifth extends Fragment implements View.OnClickListener, GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {
private static final String TAG = PostAdsFragmentFifth.class.getSimpleName();
private CustomTextView tvBackBtn;
PlaceAutocompleteFragment autocompleteFragment;
private GoogleMap mMap;
Address address;
protected GoogleApiClient mGoogleApiClient;
private Marker marker;
private SupportMapFragment mapFragment;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.activity_post_slide5, container, false);
checkGpsEnabled();
setGooglePlaces();
mapFragment = (SupportMapFragment) this.getChildFragmentManager()
.findFragmentById(R.id.map);
tvBackBtn = (CustomTextView) getActivity().findViewById(R.id.tvBack);
tvBackBtn.setVisibility(View.VISIBLE);
tvBackBtn.setOnClickListener(this);
return view;
}
@Override
public void onStart() {
super.onStart();
checkPermissions();
}
@Override
public void onDestroy() {
super.onDestroy();
if (mGoogleApiClient != null)
mGoogleApiClient.disconnect();
}
@Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.tvBack:
MixPanelEvents.addMixPanelEvents(getActivity(), "Pet Address for Back");
if (getUserVisibleHint())
((PostAdsActivity) getActivity()).gotoNext(4);
break;
}
}
private void setGooglePlaces() {
autocompleteFragment = (PlaceAutocompleteFragment) getActivity().getFragmentManager().findFragmentById(R.id.place_autocomplete_fragment);
autocompleteFragment.setHint(getResources().getString(R.string.address_hint_toast));
AutocompleteFilter typeFilter = new AutocompleteFilter.Builder()
.setTypeFilter(AutocompleteFilter.TYPE_FILTER_ADDRESS)
.build();
autocompleteFragment.setFilter(typeFilter);
autocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
@Override
public void onPlaceSelected(Place place) {
address = new Address();
address.setLatitude(place.getLatLng().latitude);
address.setLongitude(place.getLatLng().longitude);
address.setAddress(place.getAddress().toString());
address.setLandmark(place.getName().toString());
PostAdsActivity.postData.setAddress(address);
}
@Override
public void onError(Status status) {
// TODO: Handle the error.
LogUtils.i(TAG, "An error occurred: " + status);
}
});
}

}
}
}
