android studio上的百度定位的初始化

记录一下自己引入百度地图API的结果，调用了百度地图的定位，下面开始讲解：

1.下载官方百度地图SDK，详细的我就不说了，自己查就能查到了，然后根据自己的选择进行下载，别忘了申请密钥。

2.新建一个项目，导入jar包和so包，不知道的朋友可以点击下面的链接去查看如何导入：

http://blog.csdn.net/anny_lin/article/details/46763255  so包引入

jar包的引入只需要将jar包考入到libs里面，然后右键点击“add as library”就可以了

3.进行基础的配置，官方文档上有给出，当然你也可下载官方的Demo进行代码的查看与修改，我是基于官方demo进行修改的，修改后的代码如下，基本上面什么变化：

package demo.baidumap;import android.app.ProgressDialog;import android.os.Handler;import android.os.Message;import android.os.Bundle;import android.view.Menu;import android.view.MenuItem;import android.view.View;import android.widget.Button;import android.widget.CheckBox;import android.widget.EditText;import android.widget.RadioGroup;import android.widget.TextView;import com.baidu.location.LocationClient;import com.baidu.location.LocationClientOption;public class MainActivity extends AppCompatActivity {    private LocationClient mLocationClient;    private TextView LocationResult,ModeInfor;

    //开启定位按钮    private Button startLocation;    private RadioGroup selectMode,selectCoordinates;    private EditText frequence;    private LocationClientOption.LocationMode tempMode = LocationClientOption.LocationMode.Hight_Accuracy;    private String tempcoor="gcj02";    private CheckBox checkGeoLocation;    private Handler handler;    private   ProgressDialog progressDialog;    @Override    protected void onCreate(Bundle savedInstanceState) {        // TODO Auto-generated method stub        super.onCreate(savedInstanceState);        setContentView(R.layout.location);        mLocationClient = ((LocationApplication) getApplication()).mLocationClient;        LocationResult = (TextView) findViewById(R.id.textView1);        ((LocationApplication) getApplication()).mLocationResult = LocationResult;              //开启定位按钮        startLocation = (Button) findViewById(R.id.addfence);        handler=new Handler(){            @Override            public void handleMessage(Message msg) {                if (msg.what==2) {                    mLocationClient.stop();                    progressDialog.dismiss();                }            }        };        //开始定位        startLocation.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                progressDialog=ProgressDialog.show(MainActivity.this,"aa","aa");                new Thread(new Runnable() {                    @Override                    public void run() {                        InitLocation();                        mLocationClient.start();                        try {                            Thread.sleep(2000);                        } catch (InterruptedException e) {                            e.printStackTrace();                        }                        handler.sendEmptyMessage(2);                    }                }).start();            }        });    }    @Override    protected void onStop() {        // TODO Auto-generated method stub        mLocationClient.stop();        super.onStop();    }    private void InitLocation(){        LocationClientOption option = new LocationClientOption();        option.setLocationMode(tempMode);//���ö�λģʽ        option.setCoorType(tempcoor);//���صĶ�λ����ǰٶȾ�γ�ȣ�Ĭ��ֵgcj02        int span=1000;        try {            span = Integer.valueOf(frequence.getText().toString());        } catch (Exception e) {                   }        option.setScanSpan(span);//���÷���λ����ļ��ʱ��Ϊ5000ms        option.setIsNeedAddress(true);        mLocationClient.setLocOption(option);    }}

其次是application文件

package demo.baidumap;import android.app.Application;import android.os.Vibrator;import android.util.Log;import android.widget.TextView;import com.baidu.location.BDLocation;import com.baidu.location.BDLocationListener;import com.baidu.location.GeofenceClient;import com.baidu.location.LocationClient;/** */public class LocationApplication extends Application {    /**     * ��Application     */        public LocationClient mLocationClient;        public GeofenceClient mGeofenceClient;        public MyLocationListener mMyLocationListener;        public TextView mLocationResult,logMsg;        public TextView trigger,exit;        public Vibrator mVibrator;        @Override        public void onCreate() {            super.onCreate();            mLocationClient = new LocationClient(this.getApplicationContext());            mMyLocationListener = new MyLocationListener();            mLocationClient.registerLocationListener(mMyLocationListener);        }        /**         */        public class MyLocationListener implements BDLocationListener {            @Override            public void onReceiveLocation(BDLocation location) {                //Receive Location                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());                    sb.append("\ndirection : ");                    sb.append("\naddr : ");                    sb.append(location.getAddrStr());                    sb.append(location.getDirection());                } else if (location.getLocType() == BDLocation.TypeNetWorkLocation){                    sb.append("\naddr : ");                    sb.append(location.getAddrStr());                    //��Ӫ����Ϣ                    sb.append("\noperationers : ");                    sb.append(location.getOperators());                }                logMsg(sb.toString());                Log.i("BaiduLocationApiDem", sb.toString());            }        }        /**         * @param str         */        public void logMsg(String str) {            try {                if (mLocationResult != null)                    mLocationResult.setText(str);            } catch (Exception e) {                e.printStackTrace();            }        }        /**         * @author jpren         *         */    }

最后就是androidfest文件了

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="demo.baidumap" >    <application        android:name=".LocationApplication"        android:allowBackup="true"        android:icon="@mipmap/ic_launcher"        android:label="@string/app_name"        android:theme="@style/AppTheme" >        <activity            android:name=".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>        <service            android:name="com.baidu.location.f"            android:enabled="true"            android:process=":remote">            <intent-filter>                <action android:name="com.baidu.location.service_v2.2" >                </action>            </intent-filter>        </service>        <meta-data            android:name="com.baidu.lbsapi.API_KEY"            android:value="你的密钥" />    </application>    <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>    <uses-permission android:name="android.permission.VIBRATE" />    <uses-permission android:name="android.permission.WAKE_LOCK" />    <uses-permission android:name="android.permission.WRITE_SETTINGS" /></manifest>

然后就可以进行基础的定位服务了，需要注意的是，你需要在真机上进行测试，虚拟机可能显示不出结果。
