【Android】接入高德地图SDK

第一步 申请开发者权限

进入高德地图开放平台https://console.amap.com/dev/index申请认证个人开发者

第二步 创建应用

第三步 下载Android地图SDK

进入https://lbs.amap.com/api/android-sdk/download/下载 Android地图SDK，然后导入项目工程

第四步 添加依赖

app/build.gradle中添加依赖

implementation fileTree(dir: "libs", include: ["*.jar"])
           

第五步 实现地图展示代码

1.layout文件添加一个MapView

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <com.amap.api.maps.MapView
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
    </com.amap.api.maps.MapView>

</LinearLayout>
           

2.AndroidManifest文件添加权限

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.lbstest">

    <!--允许程序打开网络套接字-->
    <uses-permission android:name="android.permission.INTERNET" />
    <!--允许程序设置内置sd卡的写权限-->
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <!--允许程序获取网络状态-->
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <!--允许程序访问WiFi网络信息-->
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <!--允许程序读写手机状态和身份-->
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <!--允许程序访问CellID或WiFi热点来获取粗略的位置-->
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

    <application
        ...
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <meta-data
            android:name="com.amap.api.v2.apikey"
            android:value="ff7d55ecc5f5bc56560e69e9633dd73a" />
    </application>

</manifest>
