Android?高德地圖POI定位地址搜索功能
更新時間：2024年02月22日 14:20:17 作者：餅子會飛
這篇文章主要介紹了Android?高德地圖POI定位地址搜索功能,本文通過實(shí)例代碼給大家介紹的非常詳細(xì),對大家的學(xué)習(xí)或工作具有一定的參考借鑒價(jià)值,需要的朋友參考下吧
先上演示：
高德地圖的key申請這里就不講了，比較簡單，網(wǎng)上有很多資料，或者前往官網(wǎng)查看：官方文檔
依賴引入
項(xiàng)目使用了如下依賴：
//高德地圖
implementation 'com.amap.api:3dmap:latest.integration'
//地圖搜索功能
implementation 'com.amap.api:search:latest.integration'
//權(quán)限申請
implementation 'com.github.getActivity:XXPermissions:18.3'配置清單
<!--允許訪問網(wǎng)絡(luò)，必選權(quán)限-->
