從谷歌地圖中刪除選定的標記

Question

我通過使用onMarkerClickListener在google地圖上放置了多個標記，現在我想讓用戶從添加的標記中刪除任何標記。任何人都可以提出一些方法來做到這一點

我的標記代碼是

GoogleMap.OnMarkerClickListener listener = new    
GoogleMap.OnMarkerClickListener() { 

    @Override 
    public boolean onMarkerClick(final Marker marker) { 

     AddGeofenceFragment dFragment = new AddGeofenceFragment(); 
     // Show DialogFragment 
     dFragment.show(fm, "Dialog Fragment"); 
     return true; 
    } 

}; 

newmap.setOnMarkerClickListener(listener); 

newmap.setOnMapClickListener(new GoogleMap.OnMapClickListener() { 

    @Override 
    public void onMapClick(LatLng latLng) { 

     // Creating a marker 
     MarkerOptions markerOptions = new MarkerOptions(); 

     // Setting the position for the marker 
     markerOptions.position(latLng); 

     // Setting the title for the marker. 
     // This will be displayed on taping the marker 
     markerOptions.title(latLng.latitude + " : " + latLng.longitude); 


     // Animating to the touched position 
     newmap.animateCamera(CameraUpdateFactory.newLatLng(latLng)); 

     // Placing a marker on the touched position 
     newmap.addMarker(markerOptions); 
     Log.d("ADDED LATITUDE",String.valueOf(latLng.latitude)); 
     Log.d("ADDED LONGITUDE",String.valueOf(latLng.longitude)); 

     Toast.makeText(getApplicationContext(),"Block area updated",Toast.LENGTH_LONG).show(); 



    } 
});

，你可以通過實現接口OnMarkerClickListener到mapActivity做到這一點。那麼您需要編寫您的要求代碼以刪除方法中選定的標記：

@Override 
public boolean onMarkerClick(final Marker marker) { 
    if (marker.equals(myMarker)) { 
     //handle click here 
     marker.remove(); 
    } 
}
