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起来。

googleMap.addMarker(new MarkerOptions()
        .position(latLng)
        .title("My Spot")
        .snippet("This is my spot!")
        .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));

如果您回答此问题，请提供一个标记示例代码，该示例代码使用唯一名称引入，然后设置为可点击以打开新活动。

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 - 将标记点击回调注册到您的 googleMap 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
        }
    }
}

这是谷歌关于标记自定义的一个很好的指南

setTag(position)在向地图添加标记时。

Marker marker =  map.addMarker(new MarkerOptions()
                .position(new LatLng(latitude, longitude)));
marker.setTag(position);

getTag()setOnMarkerClickListener听者_

map.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
                @Override
                public boolean onMarkerClick(Marker marker) {
                    int position = (int)(marker.getTag());
                   //Using position get Value from arraylist 
                    return false;
                }
            });

避免使用Activity实现OnMarkerClickListener，使用本地的OnMarkerClickListener

// Not a good idea
class MapActivity extends Activity implements OnMarkerClickListener {
}

您将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<>();

您将需要一个数据模型

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);

对于单击标记事件，请使用本地 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);
        }
    });

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()

对此：

mMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener()

这一行：

public void onInfoWindowClick(Marker arg0)

对此：

public boolean onMarkerClick(Marker arg0)

并在方法“onMarkerClick”结束时：

return true;

我认为这可能对某人有帮助；）

Step 1
public class TopAttractions extends Fragment implements OnMapReadyCallback, 
GoogleMap.OnMarkerClickListener

Step 2
gMap.setOnMarkerClickListener(this);

Step 3
@Override
public boolean onMarkerClick(Marker marker) {
    if(marker.getTitle().equals("sharm el-shek"))
        Toast.makeText(getActivity().getApplicationContext(), "Hamdy", Toast.LENGTH_SHORT).show();
    return false;

下面的 Kotlin 代码可以帮助你

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mMap.setOnMarkerClickListener(this);在onMapReady(GoogleMap googleMap)方法中添加了一个。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;
}

}

                    .title("My Spot")
                    .snippet("This is my spot!")
                    .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));
        ......
    }

    @Override
