Android app'上的图纸位置坐标；s页

我正在尝试在我的应用程序中添加如下功能： 我想获得用户的坐标（从GPS）并在空白地图上显示用户，没有任何街道/建筑物或任何地图视图，只有一个空白页面，例如用户将显示在页面中心，其他保存的位置坐标将标记在页面上相对于用户的位置。

---

例如，如果用户停留在一个坐标上，并且一个标记在他以北5米处，那么我想在页面中央显示该用户，该标记将在应用程序上显示在他以北。

您可以使用谷歌地图。它可以让您获得用户位置，还可以在地图上标记保存的用户位置。查看教程

您可以使用自定义谷歌地图，使用地图向导创建空白地图。我通过将道路、标签和地标的密度设置为零创建了一张空白地图。然后你要做的就是进入更多选项>全部>几何体并禁用它

这是json，您可以使用它在应用程序中创建一个空白地图，这是我从google地图样式向导创建的

下面是示例代码。当你完成我在那里发布的谷歌地图教程（本文的第一个链接）时，你就会知道这是关于什么的

祝你好运

@Override
public void onMapReady(GoogleMap googleMap){
    MapStyleOptions style = MapStyleOptions.loadRawResourceStyle(this, R.raw.style_json);
    googleMap.setMapStyle(style);
