如何使 Android Google Maps API v2 中的标记变为可点击状态，以便它们显示带有选项的菜单或开始新的活动？我相信我目前在我的应用程序中使用“newb”方法制作了标记。我没有为它们分配名称或方法，以便能够将其与所需的其余代码链接。
googleMap.addMarker(new MarkerOptions()
.position(latLng)
.title("My Spot")
.snippet("This is my spot!")
.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));
如果您回答了这个问题，请附上一个标记的示例代码，该标记被引入一个唯一的名称，然后被设置为可点击以打开一个新活动。

Google Android Maps Api v2 中的所有标记都是可点击的。您无需为标记设置任何其他属性。 您需要做的是向您的 googleMap 注册标记点击回调并在回调中处理点击：
public class MarkerDemoActivity extends android.support.v4.app.FragmentActivity
implements OnMarkerClickListener
{
private Marker myMarker;
private void setUpMap()
{
.......
googleMap.setOnMarkerClickListener(this);
myMarker = googleMap.addMarker(new MarkerOptions()
.position(latLng)
.title("My Spot")
.snippet("This is my spot!")
.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));
......
}
@Override
public boolean onMarkerClick(final Marker marker) {
if (marker.equals(myMarker))
{
//handle click here
}
}
}

OnInfoWindowClickListenerCallback。 GoogleMap 中有一个方法：googleMap.setOnInfoWindowClickListener(listener);
setTag(position) 同时向地图添加标记。
Marker marker = map.addMarker(new MarkerOptions()
.position(new LatLng(latitude, longitude)));
marker.setTag(position);
getTag() setOnMarkerClickListener 监听器
map.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
@Override
public boolean onMarkerClick(Marker marker) {
int position = (int)(marker.getTag());
//Using position get Value from arraylist
return false;
}
});
【讨论】：
避免使用Activity实现OnMarkerClickListener，使用本地的OnMarkerClickListener
// Not a good idea
class MapActivity extends Activity implements OnMarkerClickListener {
}
您需要一张地图来查找链接到标记的原始数据模型
private Map<Marker, Map<String, Object>> markers = new HashMap<>();
你需要一个数据模型
private Map<String, Object> dataModel = new HashMap<>();
将一些数据放入数据模型中
dataModel.put("title", "My Spot");
dataModel.put("snipet", "This is my spot!");
dataModel.put("latitude", 20.0f);
dataModel.put("longitude", 100.0f);
使用数据模型创建新标记时，将两者都添加到制造商地图
Marker marker = googleMap.addMarker(markerOptions);
markers.put(marker, dataModel);
对于点击标记事件，使用本地 OnMarkerClickListener：
@Override
public void onMapReady(GoogleMap googleMap) {
// grab for laters
this.googleMap = googleMap;
googleMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
@Override
public boolean onMarkerClick(Marker marker) {
Map dataModel = (Map)markers.get(marker);
String title = (String)dataModel.get("title");
markerOnClick(title);
return false;
}
});
mapView.onResume();
showMarkers();
ZoomAsync zoomAsync = new ZoomAsync();
zoomAsync.execute();
}
为了显示信息窗口，从标记图中检索原始数据模型：
@Override
public void onMapReady(GoogleMap googleMap) {
this.googleMap = googleMap;
googleMap.setOnInfoWindowClickListener(new GoogleMap.OnInfoWindowClickListener() {
@Override
public void onInfoWindowClick(Marker marker) {
Map dataModel = (Map)markers.get(marker);
String title = (String)dataModel.get("title");
infoWindowOnClick(title);
}
});
【讨论】：
另一种解决方案：您可以通过标题获取标记
public class MarkerDemoActivity extends android.support.v4.app.FragmentActivity implements OnMarkerClickListener
{
private Marker myMarker;
private void setUpMap()
{
.......
googleMap.setOnMarkerClickListener(this);
myMarker = googleMap.addMarker(new MarkerOptions()
.position(latLng)
.title("My Spot")
.snippet("This is my spot!")
.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));
......
}
@Override
public boolean onMarkerClick(final Marker marker)
{
String name= marker.getTitle();
if (name.equalsIgnoreCase("My Spot"))
{
//write your code here
}
}
}

这是我的带有 4 个可点击标记的地图活动的完整代码。单击标记会显示信息窗口，单击信息窗口后，您将进入另一个活动：英语、德语、西班牙语或意大利语。如果你想在 OnInfoWindowClickListener 的情况下使用 OnMarkerClickListener，你只需要交换这一行：
mMap.setOnInfoWindowClickListener(new GoogleMap.OnInfoWindowClickListener()
到这里：
mMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener()
这一行：
public void onInfoWindowClick(Marker arg0)
到这里：
public boolean onMarkerClick(Marker arg0)
在方法“onMarkerClick”的末尾：
return true;

以下 Kotlin 代码可以帮助您
创建标记
for (i in arrayList.indices) {
val marker = googleMap!!.addMarker(
MarkerOptions().position(
LatLng(
arrayList[i].location_latitude!!.toDoubleOrNull()!!,
arrayList[i].location_latitude!!.toDoubleOrNull()!!
)
).title(arrayList[i].business_name)
.icon(BitmapDescriptorFactory.fromResource(R.drawable.ic_marker))
)
marker.tag = i
}
标记点击
googleMap!!.setOnMarkerClickListener { marker ->
Log.d(TAG, "Clicked on ${marker.tag}")
true
}

我在onMapReady(GoogleMap googleMap) 方法中添加了mMap.setOnMarkerClickListener(this);。因此，每次单击标记时，它都会在 toast 方法中显示文本名称。
public class DemoMapActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener,OnMapReadyCallback, GoogleMap.OnMarkerClickListener {
private GoogleMap mMap;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_places);
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
}
@Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
double lat=0.34924212701428;
double lng=32.616554024713;
String venue = "Capital Shoppers City";
LatLng location = new LatLng(lat, lng);
mMap.addMarker(new MarkerOptions().position(location).title(venue)).setTag(0);
CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLng(location);
CameraUpdate zoom = CameraUpdateFactory.zoomTo(16);
mMap.moveCamera(cameraUpdate);
mMap.animateCamera(zoom);
mMap.setOnMarkerClickListener(this);
}
@Override
public boolean onMarkerClick(final Marker marker) {
// Retrieve the data from the marker.
Integer clickCount = (Integer) marker.getTag();
// Check if a click count was set, then display the click count.
if (clickCount != null) {
clickCount = clickCount + 1;
marker.setTag(clickCount);
Toast.makeText(this,
marker.getTitle() +
" has been clicked ",
Toast.LENGTH_SHORT).show();
}
// Return false to indicate that we have not consumed the event and that we wish
// for the default behavior to occur (which is for the camera to move such that the
// marker is centered and for the marker's info window to open, if it has one).
return false;
}
