Unity高德LBS

本文主要是介绍Unity高德LBS，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

一、准备

高德开发者页面注册产品

1.1 http://www.cnblogs.com/U-tansuo/archive/2013/04/25/unity3d_android_sign.html

1.2填写应用应用信息

1.3下载Android 定位SDK

http://lbs.amap.com/api/android-location-sdk/locationsummary

解压得到 AMap_Location_V3.6.1_20171012.jar

二．新建Eclipse项目

2.1首先新建一个Android工程，在最小SDK版本里选4.0以上，不然在Unity打包的时候会报错。

2.2导入AMap_Location_V3.6.1_20171012.jar和Unity提供的JAR库classes.jar

位置：

D:\Program Files\Unity17103\Editor\Data\PlaybackEngines\AndroidPlayer\Variations\il2cpp\Development\Classes

2.3 Java代码

package com.mirror.locationtest;import android.os.Bundle;
import android.util.Log;import com.amap.api.location.AMapLocation;
import com.amap.api.location.AMapLocationClient;
import com.amap.api.location.AMapLocationClientOption;
import com.amap.api.location.AMapLocationClientOption.AMapLocationMode;
import com.amap.api.location.AMapLocationListener;
import com.unity3d.player.UnityPlayerActivity;;public class MainActivity extends UnityPlayerActivity  {//声明AMapLocationClient类对象public AMapLocationClient mLocationClient = null;//声明AMapLocationClientOption对象public AMapLocationClientOption mLocationOption = null;//定位回调字符串private String LocationInfo = "Init String~";@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);}public String GetInfo(){startLocation();return LocationInfo;}@Overrideprotected void onStart() {// TODO Auto-generated method stubsuper.onStart();}private void startLocation(){//初始化定位mLocationClient = new AMapLocationClient(getApplicationContext());//设置定位回调监听
        mLocationClient.setLocationListener(mLocationListener);//初始化AMapLocationClientOption对象mLocationOption = new AMapLocationClientOption();//设置定位模式为AMapLocationMode.Hight_Accuracy，高精度模式。
        mLocationOption.setLocationMode(AMapLocationMode.Hight_Accuracy);//设置定位间隔,单位毫秒,默认为2000ms，最低1000ms。mLocationOption.setInterval(2000);//给定位客户端对象设置定位参数
        mLocationClient.setLocationOption(mLocationOption);//启动定位
        mLocationClient.startLocation();}public AMapLocationListener mLocationListener = new AMapLocationListener() {@Overridepublic void onLocationChanged(AMapLocation location) {// TODO Auto-generated method stubif (location != null) {if (location.getErrorCode() == 0) {StringBuffer sb = new StringBuffer(256);sb.append("时间: ");sb.append(location.getTime());sb.append("\n纬度：");sb.append(location.getLatitude());sb.append("\n纬度：");sb.append(location.getLongitude());sb.append("\n精度：");sb.append(location.getAccuracy());sb.append("\n地址：");sb.append(location.getAddress());sb.append("\n国家信息：");sb.append(location.getCountry());sb.append("\n省信息：");sb.append(location.getProvince());sb.append("\n城市信息：");sb.append(location.getCity());sb.append("\n城区信息：");sb.append(location.getDistrict());sb.append("\n街道信息：");sb.append(location.getStreet());sb.append("\n街道门牌号信息：");sb.append(location.getStreetNum());sb.append("\n城市编码：");sb.append(location.getCityCode());sb.append("\n地区编码：");sb.append(location.getAdCode());sb.append("\n定位点AOI信息：");sb.append(location.getAoiName());LocationInfo = sb.toString();}else {mLocationClient.stopLocation();mLocationClient.startLocation();LocationInfo ="定位出现错误,"+location.getErrorCode()+","+location.getErrorInfo();}}else{LocationInfo="定位彻底失败";}}};
}

2.4AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"package="com.mirror.locationtest"android:versionCode="1"android:versionName="1.0" ><uses-sdkandroid:minSdkVersion="16"android:targetSdkVersion="21" /><uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission><uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission><uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission><uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission><uses-permission android:name="android.permission.INTERNET"></uses-permission><uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission><applicationandroid:allowBackup="true"android:icon="@drawable/ic_launcher"android:label="@string/app_name"android:theme="@style/AppTheme" ><service android:name="com.amap.api.location.APSService"></service><activityandroid:name="com.mirror.locationtest.MainActivity"android:label="@string/app_name" ><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="041cc66fb397b6f30cdb8683d24c7833">          </meta-data></application></manifest>

2.5Eclipse选中我们的工程文件夹，可以先点击工具栏的Project->clean，再Project->Build Project。然后右键Export，选导出为JAR文件导出jar包

2.6Unity部分

将安卓工程的文件拷贝到Unity工程的Plugins->Android文件夹里。没有这个目录的话需要自己创建一个。文件夹目录如下，把我们刚刚导出的JAR文件放在的bin文件夹中，另外还需要把我们的安卓工程目录里把libs文件夹和res文件夹以及AndroidManifest文件拷贝进去，注意拷贝完要把libs文件夹里面的classes.jar文件删掉，不然文件会冲突

2.7代码GetLocationInfo.CS

using UnityEngine;
using UnityEngine.UI;public class GetLocationInfo : MonoBehaviour {public Text text;// Use this for initializationvoid Start(){InvokeRepeating("StartLocation", 1, 5);}public void StartLocation(){AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");AndroidJavaObject jo = jc.GetStatic<AndroidJavaObject>("currentActivity");text.text = jo.Call<string>("GetInfo");}
}
