【移動應用開發(fā)技術】Android怎么調(diào)用高德地圖定位

這篇文章主要為大家展示了“Android怎么調(diào)用高德地圖定位”，內(nèi)容簡而易懂，條理清晰，希望能夠幫助大家解決疑惑，下面讓在下帶領大家一起研究并學習一下“Android怎么調(diào)用高德地圖定位”這篇文章吧。在App中使用地圖定位十分常見，購物功能的可以直接定位當前位置，發(fā)動態(tài)功能可以定位當前位置發(fā)出，社交功能可以定位周邊用戶等等。這里我使用高德地圖定位當前位置并顯示地址和經(jīng)緯度。先上效果圖：實現(xiàn)步驟：1.創(chuàng)建應用獲取key：接入第三方無一例外，去高德地圖官網(wǎng)注冊賬號并創(chuàng)建應用。填入包名和keystore的Sha1。創(chuàng)建應用獲取Sha1，輸入命令keytool-v-list-keystorekeystore文件路徑，我在這里通過控制臺獲取調(diào)試版的：進入.android目錄cd

.android輸入命令獲取keytool

-v

-list

-keystore

debug.keystore過程截圖：創(chuàng)建完成獲取Key：2.接入SDK添加定位庫compile

'com.amap.api:location:egration'添加2D地圖庫compile

'com.amap.api:map2d:egration'添加地圖權限：

<uses-permission

android:name="android.permission.INTERNET"

<uses-permission

android:name="android.permission.WRITE_EXTERNAL_STORAGE"

<meta-data

android:name="com.amap.api.v2.apikey"

android:value="57b811b21061501ee320e171568f0dac"

/>3.代碼實現(xiàn)（帶每一步功能注釋）：實現(xiàn)思路：創(chuàng)建MapView顯示地圖；設置定位定位監(jiān)聽，設置定位參數(shù)，在activate激活后啟動定位；在定位回調(diào)中獲取經(jīng)緯度，在將地圖移動到定位位置，在該經(jīng)緯度上添加覆蓋圖標。詳細代碼如下：地圖控件：

android:layout_height="match_parent"/>定位類AmapActivity完整代碼：import
