Android定位開發之百度定位、高德定位、騰訊定位，三足鼎立一起爲我所用！

這幾天的項目不是很緊，於是想爲未來可能要做的項目做一些技術儲備。

下一個項目很有可能是定位開發，需要用到手機定位功能，於是查了查現在比較流行的第三方定位，最火的基本上就是百度定位>高德定位>騰訊定位了。

想了想不如做一個DEMO把三種定位方式混合一下試試。

BaiduLocTool.java

package com.dhcc.mixlocation;

import android.content.Context;

import com.baidu.location.BDLocation;
import com.baidu.location.BDLocationListener;
import com.baidu.location.LocationClient;
import com.baidu.location.LocationClientOption;
import com.baidu.location.LocationClientOption.LocationMode;

public class BaiduLocTool implements BDLocationListener{
	
	public LocationClient mLocationClient;
	
	public LocationClient getmLocationClient() {
		return mLocationClient;
	}

	private Context mContext;
	
	public BaiduLocTool(Context context){
		
		mContext=context;
	}
	
	
	public void init(){
		
		mLocationClient = new LocationClient(mContext);
		
		InitLocation();
		
		mLocationClient.registerLocationListener(this);
		
		mLocationClient.start();
	}
	
	private void InitLocation(){
		LocationClientOption option = new LocationClientOption();
		option.setLocationMode(LocationMode.Hight_Accuracy);//設置定位模式
		option.setScanSpan(1000);//設置發起定位請求的間隔時間爲5000ms
		option.setIsNeedAddress(true);
		mLocationClient.setLocOption(option);
	}

	@Override
	public void onReceiveLocation(BDLocation location) {
		// TODO Auto-generated method stub
		((MainActivity)mContext).phoneCall("百度定位:"+"緯度:"+location.getLatitude()+" | "+"經度:"+location.getLongitude()+" | "+"反地理編碼:"+location.getAddrStr());
		mLocationClient.stop();
	}
	
	public void destroyLocManager(){
		if(mLocationClient!=null)
		mLocationClient.stop();
		mLocationClient=null;
	}

}

GaodeLocTool.java

public class GaodeLocTool implements AMapLocationListener{
	
	Context mContext;
	private LocationManagerProxy mLocationManagerProxy;
	
	public GaodeLocTool(Context context){
		
		this.mContext=context;
		
	}
	
	public void init(){
		
		
		mLocationManagerProxy = LocationManagerProxy.getInstance(mContext);
		
		  mLocationManagerProxy.requestLocationData(
	                LocationProviderProxy.AMapNetwork, 1000, 15, this);
	        mLocationManagerProxy.setGpsEnable(true);
		
	}

	@Override
	public void onLocationChanged(Location location) {
		// TODO Auto-generated method stub
		Log.e("onLocationChanged", "Location");
	}

	@Override
	public void onProviderDisabled(String arg0) {

		Log.e("onProviderDisabled", "onProviderDisabled");
	}

	@Override
	public void onProviderEnabled(String arg0) {
		// TODO Auto-generated method stub
		Log.e("onProviderEnabled", "onProviderEnabled");
	}

	@Override
	public void onStatusChanged(String arg0, int arg1, Bundle arg2) {
		// TODO Auto-generated method stub
		Log.e("onStatusChanged", "onStatusChanged");
	}

	@Override
	public void onLocationChanged(AMapLocation location) {
		// TODO Auto-generated method stub
		Log.e("onLocationChanged", "AMapLocation");
		((MainActivity)mContext).phoneCall("高德定位:"+"混合定位方式:"+location.getProvider()+" | "+"緯度:"+location.getLatitude()+" | "+"經度:"+location.getLongitude()+" | "+"反地理編碼:"+location.getAddress());	
		mLocationManagerProxy.removeUpdates(this);
	}
	
	
	
	public void destroyLocManager() {

	        if (mLocationManagerProxy != null) {
	        	mLocationManagerProxy.removeUpdates(this);
	        	mLocationManagerProxy.destroy();
	        }
	        mLocationManagerProxy = null;

	}

}

記錄一下開發中遇到的問題：

百度地圖：沒什麼問題，用起來很方便。

高德地圖：LocationProviderProxy.AMapNetwork  只支持網絡定位，無法純GPS定位，如果想要純GPS定位就必須把這個參數改成LocationManagerProxy.GPS_PROVIDER。很蛋疼，這裏需要自己來邏輯判斷一下。

騰訊地圖：如果想要純GPS定位的話，需要把定位座標改成地球座標：mLocationManager.setCoordinateType(TencentLocationManager.COORDINATE_TYPE_WGS84);

但是面臨的問題是這個座標沒法反地理編碼。如果想反地理編碼，就必須把座標改成火星座標，mLocationManager.setCoordinateType(TencentLocationManager.COORDINATE_TYPE_GCJ02);  

但是這樣又沒法純GPS定位，所以我個人覺得騰訊定位只要用他的網絡定位就好了，不要用他的GPS定位了 好麻煩。

在我所在的位置測試的話，三種定位的網絡定位，反地理編碼最準確的是：騰訊定位，其次是百度定位，最差的是高德定位。
