Android手机百度地图开发步骤

关于百度地图的开发，百度地图API有很详细的开发资料，所以本篇文章不在于写开发技术，而在于开发步骤

1.导入库文件

我们想要开发百度地图，那么首先需要导入库文件（这些库文件可以从这里下载）

将liblocSDK4d.so文件拷贝到libs/armeabi目录下。

将locSDK4.2.jar文件拷贝到工程的libs目录下。

  

在工程属性->Java Build Path->Libraries中选择“AddJARs”，

选定locSDK4.2.jar，确定后返回。这样您就可以在程序中使用百度定位SDK了。

2.设置AndroidManifest.xml

在application标签中声明service组件,每个app拥有自己单独的定位service

        <service 
            android:name="com.baidu.location.f" 
            android:enabled="true" 
            android:process=":remote">
	</service>

3.声明使用权限

	<permission android:name="android.permission.BAIDU_LOCATION_SERVICE" >
    </permission>

    <uses-permission android:name="android.permission.BAIDU_LOCATION_SERVICE" >
    </uses-permission>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" >
    </uses-permission>
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" >
    </uses-permission>
    <uses-permission android:name="android.permission.INTERNET" >
    </uses-permission>
    <uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" >
    </uses-permission>
    <!-- <uses-permission android:name="android.permission.WRITE_APN_SETTINGS"></uses-permission> -->
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" >
    </uses-permission>
    <uses-permission android:name="com.android.launcher.permission.READ_SETTINGS" />
    <uses-permission android:name="android.permission.WAKE_LOCK" >
    </uses-permission>
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.ACCESS_GPS" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <uses-permission android:name="android.permission.READ_CONTACTS" />
    <uses-permission android:name="android.permission.CALL_PHONE" />
    <uses-permission android:name="android.permission.READ_SMS" />
    <uses-permission android:name="android.permission.SEND_SMS" />
    <!-- SDK1.5需要android.permission.GET_TASKS权限判断本程序是否为当前运行的应用? -->
    <uses-permission android:name="android.permission.GET_TASKS" />
    <uses-permission android:name="android.permission.CAMERA" >
    </uses-permission>
    <uses-permission android:name="android.permission.RECORD_AUDIO" >
    </uses-permission>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" >
    </uses-permission>
    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
    <uses-permission android:name="android.permission.BROADCAST_STICKY" />
    <uses-permission android:name="android.permission.WRITE_SETTINGS" />
    <!-- 来电消音 -->
    <uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" >
    </uses-permission>
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
    
	<uses-permission android:name="android.permission.GET_ACCOUNTS" />  
	<uses-permission android:name="android.permission.USE_CREDENTIALS" />  
	<uses-permission android:name="android.permission.MANAGE_ACCOUNTS" />  
	<uses-permission android:name="android.permission.AUTHENTICATE_ACCOUNTS" />
	<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
	<uses-permission android:name="android.permission.WRITE_SETTINGS" />  
	<uses-permission android:name="android.permission.READ_PHONE_STATE" />

4.设置AcessKey

使用SDK4.2需要在Mainfest.xml设置Accesskey，设置有误会引起定位和地理围栏服务不能正常使用，必须进行Accesskey的正确设置。

设置AccessKey，在application标签中加入

备注：value = "key"的key是开发者申请的key，关于Key的申请参考开发者key

		<meta-data  
        	android:name="com.baidu.lbsapi.API_KEY"  
        	android:value="key" />

5.使用前初始化

import com.baidu.mapapi.SDKInitializer;

import android.app.Application;

public class DemoApplication extends Application
{
	@Override
	public void onCreate()
	{
		super.onCreate();
		// 在使用 SDK 各组间之前初始化 context 信息，传入 ApplicationContext
		SDKInitializer.initialize(this);
	}
}

同时在Mainfest.xml的Application加入如下一行

        android:name="com.phonemap.DemoApplication"

6.设置显示界面

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

</LinearLayout>

7.实现定位操作

import java.util.Timer;
import java.util.TimerTask;

import com.baidu.location.BDLocation;
import com.baidu.location.BDLocationListener;
import com.baidu.location.LocationClient;
import com.baidu.location.LocationClientOption;
import com.baidu.mapapi.map.BaiduMap;
import com.baidu.mapapi.map.BitmapDescriptor;
import com.baidu.mapapi.map.BitmapDescriptorFactory;
import com.baidu.mapapi.map.CircleOptions;
import com.baidu.mapapi.map.MapStatusUpdate;
import com.baidu.mapapi.map.MapStatusUpdateFactory;
import com.baidu.mapapi.map.MapView;
import com.baidu.mapapi.map.Marker;
import com.baidu.mapapi.map.MarkerOptions;
import com.baidu.mapapi.map.MyLocationData;
import com.baidu.mapapi.map.OverlayOptions;
import com.baidu.mapapi.map.Stroke;
import com.baidu.mapapi.map.TextOptions;
import com.baidu.mapapi.map.BaiduMap.OnMarkerClickListener;
import com.baidu.mapapi.model.LatLng;

import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.widget.Toast;

public class MainActivity extends Activity
{
	private MapView mMapView;
	
	// 定位相关
	LocationClient mLocClient;
	public MyLocationListenner myListener = new MyLocationListenner();
	BaiduMap mBaiduMap;
	
	boolean isFirstLoc = true;// 是否首次定位
	private Marker mMarker;
	BitmapDescriptor bd = BitmapDescriptorFactory
			.fromResource(R.drawable.icon_gcoding);
	BitmapDescriptor bdGround = BitmapDescriptorFactory
			.fromResource(R.drawable.ground_overlay);
	
	public final double tbox_latitude = 30.57;
	public final double tbox_longitude = 114.02;
	
	static final int REFRESH = 0;
	//定时器设置
	Timer timer = new Timer();
	TimerTask task = new TimerTask()
	{
		@Override
		public void run()
		{
			Message message = new Message();
			message.what = REFRESH;
			handler.sendMessage(message);
		}
	};
	
	Handler handler = new Handler()
	{
		public void handleMessage(Message msg)
		{
			switch (msg.what)
			{
			case REFRESH:
				RefreshData();
				break;
			default:
				break;
			}
		}
	};
	
	public Thread myThread = new Thread(new Runnable()
	{
		@Override
		public void run()
		{}
	});
	
	public void RefreshData()
	{}

	@Override
	protected void onCreate(Bundle savedInstanceState)
	{
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		
		//在使用SDK各组件之前初始化context信息，传入ApplicationContext  
        //注意该方法要再setContentView方法之前实现  
        //SDKInitializer.initialize(getApplicationContext());
        
		setContentView(R.layout.tbox_location);
		
		// 初始化地图
		mMapView = (MapView) findViewById(R.id.bmapView);
		mBaiduMap = mMapView.getMap();
		// 开启定位图层
		mBaiduMap.setMyLocationEnabled(true);
		// 定位初始化
		mLocClient = new LocationClient(this);
		mLocClient.registerLocationListener(myListener);
		LocationClientOption option = new LocationClientOption();
		option.setOpenGps(true);// 打开gps
		option.setCoorType("bd09ll"); // 设置坐标类型
		//国测局经纬度坐标系gcj02、百度墨卡托坐标系bd09、 百度经纬度坐标系bd09ll
		option.setScanSpan(1000);
		mLocClient.setLocOption(option);
		mLocClient.start();
		
		mBaiduMap.setOnMarkerClickListener(new OnMarkerClickListener() {
			public boolean onMarkerClick(final Marker marker) {
				if (marker == mMarker) {
					Toast.makeText(TboxActivity.this, "TBOX位置信息", Toast.LENGTH_LONG).show();
				}
				return true;
			}
		});
		
		//开启定时器
		timer.schedule(task,1000,1000);
		//开启线程
		myThread.start();
	}
	
	/**
	 * 定位SDK监听函数
	 */
	public class MyLocationListenner implements BDLocationListener {

		@Override
		public void onReceiveLocation(BDLocation location) {
			// map view 销毁后不在处理新接收的位置
			if (location == null || mMapView == null)
				return;
			MyLocationData locData = new MyLocationData.Builder()
					.accuracy(location.getRadius())
					// 此处设置开发者获取到的方向信息，顺时针0-360
					.direction(100).latitude(location.getLatitude())
					.longitude(location.getLongitude()).build();
			mBaiduMap.setMyLocationData(locData);
			if (isFirstLoc) {
				isFirstLoc = false;
				LatLng ll = new LatLng(location.getLatitude(),
						location.getLongitude());
				MapStatusUpdate u = MapStatusUpdateFactory.newLatLng(ll);
				mBaiduMap.animateMapStatus(u);
			}
		}

		public void onReceivePoi(BDLocation poiLocation) {
		}
	}
	
	@Override
	protected void onPause() {
		super.onPause();
		// activity 暂停时同时暂停地图控件
		mMapView.onPause();
	}
	
	@Override
	protected void onResume() {
		super.onResume();
		// activity 恢复时同时恢复地图控件
		mMapView.onResume();
	}
	
	@Override
	protected void onDestroy() {
		super.onDestroy();
		// 退出时销毁定位
		mLocClient.stop();
		// 关闭定位图层
		mBaiduMap.setMyLocationEnabled(false);
		mMapView.onDestroy();
		mMapView = null;
	}
}

8.一个简易的定位操作就实现了

效果如图

ok，这样一个简单的定位功能就做好了。
