android 百度地图定位功能实现

历经几天时间，终于把定位功能给实现了，可谓是费劲千辛万苦啊，有定位知识还有图层知识，在这里我把代码给大家贴出来，一起分享一下下啦。

package com.example.foreveross.office;

import com.baidu.location.BDLocation;
import com.baidu.location.BDLocationListener;
import com.baidu.location.LocationClient;
import com.baidu.location.LocationClientOption;
import com.baidu.mapapi.BMapManager;
import com.baidu.mapapi.map.LocationData;
import com.baidu.mapapi.map.MKMapViewListener;
import com.baidu.mapapi.map.MapController;
import com.baidu.mapapi.map.MapPoi;
import com.baidu.mapapi.map.MapView;
import com.baidu.mapapi.map.MyLocationOverlay;
import com.baidu.platform.comapi.basestruct.GeoPoint;
import com.example.wenandroid.R;

import android.app.Activity;
import android.content.res.Configuration;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.view.Menu;
import android.widget.FrameLayout;
import android.widget.Toast;

public class MapActivity extends Activity {
	BMapManager mBMapMan = null;
	MapView mMapView = null;
	MapController mMapController;
	MyLocationOverlay mLocationOverlay;
	LocationData locData = null;
	LocationClient mLocClient;
	public MyLocationListenner myListener = new MyLocationListenner();

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		mBMapMan = new BMapManager(getApplication());
		mBMapMan.init("BB3299207a600b8a035b76982adde60f", null);
		setContentView(R.layout.activity_main);
		mMapView = (MapView) findViewById(R.id.bmapsView);
		mMapView.setBuiltInZoomControls(true);
		// 设置启用内置的缩放控件
		mMapController = mMapView.getController();
		mMapController.setZoom(12);// 设置地图zoom级别
		
		// 定位初始化
		mLocClient = new LocationClient(this);
		locData = new LocationData();
		mLocClient.registerLocationListener(myListener);
		LocationClientOption option = new LocationClientOption();
		option.setOpenGps(true);// 打开gps
		option.setCoorType("bd09ll"); // 设置坐标类型
		option.setScanSpan(5000);
		mLocClient.setLocOption(option);
		mLocClient.start();

		// 定位图层初始化
		mLocationOverlay = new MyLocationOverlay(mMapView);
		// 设置定位数据
		mLocationOverlay.setData(locData);
		// 添加定位图层
		mMapView.getOverlays().add(mLocationOverlay);
		mLocationOverlay.enableCompass();
		// 修改定位数据后刷新图层生效
		mMapView.refresh();

	}
	//实现监听器
	 public class MyLocationListenner implements BDLocationListener {
	    	
	        @Override
	        public void onReceiveLocation(BDLocation location) {
	            if (location == null)
	                return ;
	            
	            locData.latitude = location.getLatitude();
	            locData.longitude = location.getLongitude();
	            //如果不显示定位精度圈，将accuracy赋值为0即可
	            locData.accuracy = location.getRadius();
	            locData.direction = location.getDerect();
	            //更新定位数据
	            mLocationOverlay.setData(locData);
	            //更新图层数据执行刷新后生效
	            mMapView.refresh();
	            //是手动触发请求或首次定位时，移动到定位点
	            
	            mMapController.animateTo(new GeoPoint((int)(locData.latitude* 1e6), (int)(locData.longitude *  1e6)));
	        }
	        
	        public void onReceivePoi(BDLocation poiLocation) {
	            if (poiLocation == null){
	                return ;
	            }
	        }
	    }

	@Override
	protected void onDestroy() {
		// TODO Auto-generated method stub
		mMapView.destroy();
		if (mBMapMan != null) {
			mBMapMan.destroy();
			mBMapMan = null;
		}
		super.onDestroy();
	}

	@Override
	protected void onPause() {
		// TODO Auto-generated method stub
		mMapView.onPause();
		if (mBMapMan != null) {
			mBMapMan.stop();
		}
		super.onPause();
	}

	@Override
	protected void onResume() {
		// 获取位置管理者，视图根据位置监听更新位置
		mLocationOverlay.getMyLocation();
		mLocationOverlay.enableCompass();
		mMapView.onResume();
		if (mBMapMan != null) {
			mBMapMan.start();
		}
		super.onResume();
	}

}

需要用到的jar包大家可以到百度地图api网站上下载。主要依赖于下列包：

manifest.xml配置如下：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.wenandroid"
    android:versionCode="1"
    android:versionName="1.0" >

    <supports-screens android:largeScreens="true"
            android:normalScreens="true"
            android:smallScreens="true"
            android:resizeable="true"
            android:anyDensity="true">
    </supports-screens>
    
    <uses-sdk
        android:minSdkVersion="3" />

    <uses-permission  android:name="android.permission.SET_WALLPAPER"/>
    
    <application
        android:allowBackup="true"
        android:icon="@drawable/first"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.example.foreveross.office.MapActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        
        
         <service android:name="com.baidu.location.f" android:enabled="true"
			android:process=":remote">
	<!--  		<intent-filter>
				<action android:name="com.baidu.location.service_v2.9"></action>
			</intent-filter>-->
		</service>
    </application>
</manifest>

界面只有一个mapview地图控件，在此列出activity_main.xml：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    >
    
    <com.baidu.mapapi.map.MapView android:id="@+id/bmapsView"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:clickable="true" />
    >

</LinearLayout>
