The following code sample demonstrates how to add a basic marker to a 3D map by
caling the addMarker
method. To use this code sample, follow the instructions in Setup
and Add a 3D map to your app
to set up your Android Studio project with a basic 3D map. Then, add the
following code to the MainActivity.kt
file:
// Add imports
import
com.google.android.gms.maps3d.model.latLngAltitude
...
// Add to the onMap3DViewReady method, after the googleMap3D object has been initialized
googleMap3D
.
setMapMode
(
Map3DMode
.
SATELLITE
)
googleMap3D
.
setCamera
(
camera
{
center
=
latLngAltitude
{
latitude
=
52.51974795
longitude
=
13.40715553
altitude
=
150.0
}
heading
=
252.7
tilt
=
79.0
range
=
1500.0
}
)
// Add a marker using absolute altitude positioning
googleMap3D
.
addMarker
(
markerOptions
{
position
=
latLngAltitude
{
latitude
=
52.519605780912585
longitude
=
13.406867190588198
altitude
=
150.0
}
label
=
"Absolute (150m)"
altitudeMode
=
AltitudeMode
.
ABSOLUTE
isExtruded
=
true
isDrawnWhenOccluded
=
true
collisionBehavior
=
CollisionBehavior
.
REQUIRED_AND_HIDES_OPTIONAL
})
Listen for marker click events
To listen for click events on a marker, call setClickListener
on
the marker object. The following example shows how to set a click listener on a
marker:
marker
.
setClickListener
{
lifecycleScope
.
launch
(
Dispatchers
.
Main
)
{
Toast
.
makeText
(
this
@MarkersActivity
,
"Clicked on marker:
${
marker
.
label
}
"
,
Toast
.
LENGTH_SHORT
)
.
show
()
}
}
Note that the click handler does not run on the Main (or UI) thread. If you
want to make changes to the UI (such as showing a Toast message), you must
switch to the Main thread. For Kotlin, you can do this using lifecycleScope.launch(Dispatchers.Main)
.
