onclick of map

        @Override
public void onMapClick(LatLng point) {
    // TODO Auto-generated method stub
    double lat = point.latitude;
    double lng = point.longitude;

    // Add marker of destination point

            try {
                Geocoder geocoder;
                List<Address> addresses;
                geocoder = new Geocoder(BookCabScreen.this);
                if (lat != 0 || lng != 0) {
                    addresses = geocoder.getFromLocation(lat, lng, 1);
                    String address = addresses.get(0).getAddressLine(0);
                    String city = addresses.get(0).getAddressLine(1);
                    String country = addresses.get(0).getAddressLine(2);
                    Log.d("TAG", "address = " + address + ", city =" + city

                    btnStopPoint.setEnabled(true);

                    mJbBookCab.setEndPointLat(lat);
                    mJbBookCab.setEndPointLng(lng);

                    Toast.makeText(BookCabScreen.this,
                            "latitude and longitude are null",
                            Toast.LENGTH_LONG).show();

                }
            } catch (Exception e) {
                e.printStackTrace();

            }


}

按钮的点击

            if (endPointMarker != null) {
            endPointMarker.remove();

            endPointMarker = null;
        }

但它不会从地图上移除？请帮

推荐答案

您添加相同的标记两次：

You are adding same marker twice:

                endPointMarker = mMap.addMarker(new MarkerOptions()
                        .position(new LatLng(lat, lng))
                        .title("Location").snippet("" + address));

                markers.add(mMap.addMarker(new MarkerOptions()
                        .position(new LatLng(lat, lng))
                        .title("Location").snippet("" + address)));

只是删除​​一个调用 GoogleMap.addMarker 。
