需要用到的jar包大家可以到百度地圖api網站上下載。主要依賴于下列包：


 
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.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> 
      <!--授予設置手機屏幕權限  -->
    <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>


界面只有一個mapview地圖控件，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>
