Andorid 集成高德地图显示，定位

多处参考官方文档：http://lbs.amap.com/api/android-location-sdk/code-samples

使用真机测试，模拟器无法定位

效果图：

1.首先是权限:

<uses-permission android:name="android.permission.INTERNET" />    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />    <uses-permission android:name="android.permission.READ_PHONE_STATE" />    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />    <uses-permission android:name="android.permission.CHANGE_CONFIGURATION" />    <uses-permission android:name="android.permission.WAKE_LOCK" />         <uses-permission android:name="android.permission.WRITE_SETTINGS" />    <application        android:allowBackup="true"        android:icon="@mipmap/ic_launcher"        android:label="@string/app_name"        android:supportsRtl="true"        android:theme="@style/AppTheme">        <activity android:name=".MainActivity">            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>            android:configChanges="orientation|keyboardHidden|screenSize"        </activity>        <!--记得写入keystore-->        <meta-data        android:name="com.amap.api.v2.apikey"        android:value="从高德官网的到的key值" />        <!-- 定位需要的服务 使用2.0的定位需要加上这个 -->        <service android:name="com.amap.api.location.APSService"></service>    </application>
具体获取key值的方法可以参照官网的文档
：http://lbs.amap.com/api/android-location-sdk/guide/create-project/get-key

复制key的地方：

2.布局文件

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:id="@+id/activity_main"    android:layout_width="match_parent"    android:layout_height="match_parent"    tools:context="text.bwie.com.xuejian1508a20171017.MainActivity">    <com.amap.api.maps2d.MapView        android:id="@+id/map"        android:layout_width="match_parent"        android:layout_height="match_parent" />//选择地图语言    <RadioGroup        android:layout_marginLeft="50dp"        android:id="@+id/check_language"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:background="@drawable/border_bg"        android:paddingRight="4dp"        android:orientation="vertical">        <RadioButton            android:id="@+id/radio_ch"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:textSize="12sp"            android:checked="true"            android:text="中文地图"/>        <RadioButton            android:id="@+id/radio_en"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:textSize="12sp"            android:text="英文地图"/>    </RadioGroup>//选择地图模式    <LinearLayout        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:orientation="horizontal"        android:layout_toRightOf="@id/check_language"        android:layout_margin="10dp"        android:layout_alignTop="@id/map">        <Button            android:id="@+id/basicmap"            android:layout_width="80dp"            android:layout_height="40dp"            android:gravity="center"            android:background="@drawable/btn_map_poi"            android:textColor="#000"            android:text="标准地图"/>        <Button            android:id="@+id/rsmap"            android:layout_width="80dp"            android:layout_height="40dp"            android:gravity="center"            android:background="@drawable/btn_map_poi"            android:textColor="#000"            android:text="卫星地图"/>    </LinearLayout></RelativeLayout>

3.导包:导入从高德官网下载的jar包

4. MainActicity的代码(此处的包名必须和在高德官网设置应用时的包名相同)
