android 百度地图定位功能实现

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" />        <permission android:name="android.permission.BAIDU_LOCATION_SERVICE"></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>   <uses-permission android:name="android.permission.VIBRATE"></uses-permission>   <uses-permission android:name="android.permission.WRITE_SETTINGS"></uses-permission>       <uses-permission android:name="android.permission.CALL_PHONE"></uses-permission>       <uses-permission android:name="android.permission.BAIDU_LOCATION_SERVICE"></uses-permission>      <uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION"></uses-permission>       <uses-permission android:name="android.permission.ACCESS_GPS"></uses-permission>         <!--授予设置手机屏幕权限  -->      <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>
