/////参考资料:高德官方:【http://lbs.amap.com/api/android-location-sdk/guide/android-location/getlocation】
主要三个文件,前提配置androidstudio的高德地图使用环境,
给几张图:
2.project展示栏里app目录下的build.grade文件,高德开发手册有提到配置
apply plugin: 'com.android.application' android { compileSdkVersion 26 buildToolsVersion "26.0.1" // 添加map的so文件 sourceSets{ main{ jniLibs.srcDirs=['libs'] } } defaultConfig { applicationId "com.example.administrator.networkorder" minSdkVersion 21 targetSdkVersion 26 versionCode 1 versionName "1.0" testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" ndk { //设置支持的SO库架构(开发者可以根据需要,选择一个或多个平台的so)设置地图 abiFilters "armeabi", "armeabi-v7a", "arm64-v8a", "x86","arm64-v8a","x86_64" } } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } dependencies { compile fileTree(include: ['*.jar'], dir: 'libs') androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', { exclude group: 'com.android.support', module: 'support-annotations' }) compile 'com.android.support:appcompat-v7:26.+' //3D地图so及jar compile 'com.amap.api:3dmap:latest.integration' //定位功能 compile 'com.amap.api:location:latest.integration' //搜索功能 compile 'com.amap.api:search:latest.integration' testCompile 'junit:junit:4.12' // compile files('libs/AMap3DMap_5.4.0_AMapNavi_5.4.0_AMapSearch_5.3.1_AMapLocation_3.6.0_20170929.jar') compile files('libs/AMap2DMap_5.2.0_AMapLocation_3.6.0_20170918.jar') }
3.AndroidManifest.xml文件,配置权限,开发key
<!--创建调试版地图key【参照:http://blog.csdn.net/a873228446/article/details/51316979】--> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.administrator.networkorder"> <!--//地图SDK(包含其搜索功能)需要的基础权限,,,,,,高德地图--> <!--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" /> <!--用于申请调用A-GPS模块--> <uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS"></uses-permission> <!--用于申请获取蓝牙信息进行室内定位--> <uses-permission android:name="android.permission.BLUETOOTH"></uses-permission> <uses-permission android:name="android.permission.BLUETOOTH_ADMIN"></uses-permission> <!--用于进行网络定位--> <!--<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>--> <!--用于访问GPS定位--> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission> <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:roundIcon="@mipmap/ic_launcher_round" android:supportsRtl="true" android:theme="@style/AppTheme"> <meta-data android:name="com.amap.api.v2.apikey" android:value="d4b100ad1856c9109720ea5f855b0638"> <!-- //开发者申请的key--> </meta-data> <service android:name="com.amap.api.location.APSService"></service> <activity android:name=".MapTest1"> <intent-filter> <!--设置启动项--> <action android:name="android.intent.action.MAIN"></action> <category android:name="android.intent.category.LAUNCHER"></category> </intent-filter> </activity> </application> </manifest>
4.布局文件,,,就一个页面
<?xml version="1.0" encoding="utf-8"?> <FrameLayout 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/map1" android:layout_width="match_parent" android:layout_height="match_parent"> </com.amap.api.maps.MapView> <Button android:id="@+id/btn_location" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="获取当前位置" /> <Button android:id="@+id/btn_dis" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="计算当前位置距离上个位置距离" android:layout_marginTop="60sp" /> </FrameLayout>
5.activity文件,,官网提到三种定位模式,高精度,低功耗,设备定位,本来用的高精度,总感觉就一两米,他就算出20,室内的,改用设备定位就好了,会不会是网络不好,设备定位用的GPS才准点,用的android5,

6.试了下,又出问题了,定位慢,还不准了,2,3米测成31米,三个都不准确,可能没用用室内定位的方式》》???,,,
