android手机百度地图开发

Love The Way You Lie 2022-01-21 00:09 347阅读 0赞

最近在做android手机上的地图开发，我们选用百度地图进行开发。

1.百度资源下载及参考文档

[http://developer.baidu.com/map/sdk-android.htm][http_developer.baidu.com_map_sdk-android.htm]

里面的开发文档介绍的很全，并且百度还提供了demo，我们可以参考demo进行开发

下面的代码的功能是，用户可以按上下左右键选择兴趣点，选中一个兴趣点后，可以点击进去看详细信息（上下按纬度来进行排序选择，左右按经度进行排序选择）
