Android OSMDroid显示多个贴图和无限滚动

我有一个简单的Android应用程序。我正在尝试显示一个简单的地图（就像我们在谷歌地图中看到的那样）。按照网站上的说明，我安装了应用程序

我有清单文件，如下所示：

首先，这仍然只是一张地图，因为我们的世界是圆的

---

其次，您可以在

MapView

对象上调用

setCrollableArealimit（）

，将视图限制为特定的

边界框

，对于我来说，以下代码有效：

map.isHorizontalMapRepetitionEnabled = false
map.isVerticalMapRepetitionEnabled = false

---

因此，除了您的代码之外，只需在设置缩放值之前添加这两个参数即可

我目前正在努力解决同样的问题。我找到了以下避免“重复”的解决方案（来自）

---

这不完全是我想要的，但它可以解决你的问题。它使用scai提到的边界框。我将进一步查看是否有其他选择

谢谢您的回答。但我们需要更多的细节。单个地图占用的区域是多少（以便我可以设置可滚动区域）？世界是圆形/球形的，但我们的表示是在平面屏幕上，所以我只需要一个地图实例。我还没有尝试过，但我的猜测是指定一个lat从

-90

到

-180

到
