当位置变化超过10米时，删除谷歌地图v2中的标记

Question

要将标记放在当前位置，我使用onLocationChange。但如果设备移动超过10米我想删除该标记，我不想要新的标记来。请有人帮忙。 我把标记放在当前位置，如下所示： 这是我的代码

@Override
public void onLocationChanged(Location location) {

    mLastLocation = location;
    if (mCurrLocationMarker != null) {
        mCurrLocationMarker.remove();
    }

    //Place current location marker
    LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());
    MarkerOptions markerOptions = new MarkerOptions();
    markerOptions.position(latLng);
    markerOptions.title("Current Position").snippet(act);
    markerOptions.icon(BitmapDescriptorFactory.fromBitmap(getBitmap(imagePath,1)));
    mCurrLocationMarker = mMap.addMarker(markerOptions);
    mMap.setOnMarkerClickListener(this);


    //move map camera
    mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
    mMap.animateCamera(CameraUpdateFactory.zoomTo(initialZoom));

    //stop location updates
    if (mGoogleApiClient != null) {
        LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, this);
    }

}
