Android获取当前位置 推荐使用百度地图SDK获取位置

这里直接引用了百度V2.6出给出的DEMO实例，经过测试，在手机客户端可以获取到当前所在的位置 首先先看一下MainActivity.java

package com.example.locationmanager;import com.baidu.location.BDLocation;import com.baidu.location.BDLocationListener;import com.baidu.location.LocationClient;import com.baidu.location.LocationClientOption;import android.app.Activity;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.TextView;public class MainActivity extends Activity {private LocationClient mLocationClient = null;private Button mStartBtn = null;private TextView mTextView = null;@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);mStartBtn = (Button)findViewById(R.id.button1);mTextView = (TextView)findViewById(R.id.textview1);mLocationClient = new LocationClient(this);LocationClientOption option = new LocationClientOption();option.setOpenGps(true); //打开gpsoption.setCoorType("bd09ll"); //设置坐标类型为bd09lloption.setPriority(WorkFirst); //设置网络优先option.setProdName("locSDKDemo2"); //设置产品线名称option.setScanSpan(5000); //定时定位，每隔5秒钟定位一次。mLocationClient.setLocOption(option);mLocationClient.registerLocationListener(new BDLocationListener() {@Overridepublic void onReceiveLocation(BDLocation location) {if (location == null)return ;StringBuffer sb = new StringBuffer(256);sb.append("time : ");sb.append(location.getTime());sb.append("\nerror code : ");sb.append(location.getLocType());sb.append("\nlatitude : ");sb.append(location.getLatitude());sb.append("\nlontitude : ");sb.append(location.getLongitude());sb.append("\nradius : ");sb.append(location.getRadius());if (location.getLocType() == BDLocation.TypeGpsLocation){sb.append("\nspeed : ");sb.append(location.getSpeed());sb.append("\nsatellite : ");sb.append(location.getSatelliteNumber());} else if (location.getLocType() == BDLocation.TypeNetWorkLocation){sb.append("\naddr : ");sb.append(location.getAddrStr());}sb.append("\nsdk version : ");sb.append(mLocationClient.getVersion());mTextView.setText(sb.toString());}public void onReceivePoi(BDLocation location){//return ;}});mStartBtn.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {if (mLocationClient == null) return ;if (mLocationClient.isStarted()){mLocationClient.stop();mStartBtn.setText("开始");} else {mLocationClient.start();mStartBtn.setText("关闭");}}});}@Overridepublic void onDestroy(){if (mLocationClient != null && mLocationClient.isStarted()){mLocationClient.stop();mLocationClient = null;}super.onDestroy();}}

接下来看一下 activity_main.xml

<?xml version="1.0" encoding="UTF-8"?><LinearLayout xmlns:android="/apk/res/android"android:layout_width="fill_parent"android:layout_height="fill_parent"android:orientation="vertical" ><TextViewandroid:id="@+id/textview1"android:layout_width="fill_parent"android:layout_height="wrap_content"android:text="hello" /><RelativeLayoutandroid:id="@+id/relativeLayout1"android:layout_width="match_parent"android:layout_height="match_parent" ><Buttonandroid:id="@+id/button1"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_alignParentBottom="true"android:text="开始" /></RelativeLayout></LinearLayout>

最后根据百度文档提出的权限问题，我们加到 AndroidMainFest.xml 中

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="/apk/res/android"package="com.example.locationmanager"android:versionCode="1"android:versionName="1.0" ><uses-sdkandroid:minSdkVersion="8"android:targetSdkVersion="16" /><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_COARSE_LOCATION" ></uses-permission><uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" ></uses-permission><uses-permission android:name="android.permission.ACCESS_WIFI_STATE" ></uses-permission><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" ></uses-permission><uses-permission android:name="android.permission.CHANGE_WIFI_STATE" ></uses-permission><uses-permission android:name="android.permission.READ_PHONE_STATE" ></uses-permission><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" ></uses-permission><uses-permission android:name="android.permission.INTERNET" /><uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" ></uses-permission><uses-permission android:name="android.permission.READ_LOGS" ></uses-permission><applicationandroid:allowBackup="true"android:icon="@drawable/ic_launcher"android:label="@string/app_name"android:theme="@style/AppTheme" ><activityandroid:name="com.example.locationmanager.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><serviceandroid:name="com.baidu.location.f"android:enabled="true"android:permission="android.permission.BAIDU_LOCATION_SERVICE"android:process=":remote" ><intent-filter><action android:name="com.baidu.location.service_v2.6" ></action></intent-filter></service></application></manifest>

运行后，就可以得到相应的位置信息了。同时我们还可以使用百度提供的其它服务，如地图标注功能等。
