Baidu Map定位显示

Location(位置):

百度地图接口的使用：
首先要到百度开发者申请一个密匙
密匙一般为:

k5N**********************8E 和 包名com.example.baidumaptest
在新建工程的时候要和在注册的时候对上，否则就会出现错误

在application中加上（最后面有，可以看看）

<meta-data            android:name="com.baidu.lbsapi.API_KEY"            android:value="k5***************fE" />

其次将其完整包下载下来
将jar文件和armebi文件夹等复制到libs下然后把jar文件Build path —add to path

main_activity.xml:

<?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/map_view"        android:layout_width="fill_parent"        android:layout_height="fill_parent"        android:clickable="true"        /></LinearLayout>

需要很多权限，能想到的基本可以写上：
