I am trying to bind a button which i have put inside a MapFragment I want my map to have a button which acts like a menu button
this is my fragment
public class MapFragment extends Fragment implements
OnMapReadyCallback,
View.OnClickListener{
public SupportMapFragment mapFragment;
private GoogleMap mMap;
FragmentMapBinding fragmentMapBinding;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
fragmentMapBinding = DataBindingUtil.inflate(inflater,R.layout.fragment_map,container,false);
View rootView = fragmentMapBinding.getRoot();
fragmentMapBinding.setHandler(this);
mapFragment = (SupportMapFragment) getChildFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
return rootView;
}
}
this is the .xml of the fragment
<layout xmlns:android="http://schemas.android.com/apk/res/android">
<data>
<variable
name="handler"
type="com.plotalong.android.activity.fragment.MapFragment"/>
</data>
<fragment xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.plotalong.android.activity.MapsActivity" >
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TEST"
android:onClick="@{() -> handler.menuButtonClick()}"
/>
</fragment>
and this is the error log I get
