尝试在Android Studio中将标记添加到Google Maps片段。当代码在android设备上运行时,代码会成功在地图上成功显示标记,但是当尝试在模拟器上运行时,标记永远不会显示

        marker = mMap.addMarker(new MarkerOptions()
                .position(new LatLng(point.getLat(), point.getLongi()))
                .title("Point: " +point.getID())
                .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_CYAN))
        );
        marker.setSnippet("Latitude: " + point.getLat() + "\nLongitude: " + point.getLongi() + "\nDescription: " + point.getDesc() + "\nLight at " + point.getTime() + " : " + point.getLight());
        marker.setTag(point.getID());
        markers.add(marker);
        marker.setVisible(true);

预期:在地图上显示自己的标记 实际:未显示任何标记

出于某些原因,该标记确实会显示:

        mMap.addMarker(new MarkerOptions()
            .position(new LatLng(10, 10))
            .title("Hello world"));

已修复,将其保留为我的耻辱的证明,标记在地图上,但模拟器设置为N. America。由于我的愚蠢,我没有缩小并看到它,但它始终没有被破坏
