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：
配置如下：

1
0 0 package="roid" 3 0 android:versionCode="1" 4 0 android:versionName="1.0" > 5 0 6 0 7 0 android:normalScreens="true" 8 0 android:smallScreens="true" 9 1 android:resizeable="true" 0 1 android:anyDensity="true"> 1 1 2 1 3 1 4 1 android:minSdkVersion="3" /> 5 1 6 1 1 1 2 2 2 2 2 2 2 2 2 2 3 3 3 3 3 4 3 36 3 7 3 android:allowBackup="true" 8 3 android:icon="@drawable/first" 9 4 android:label="@string/app_name" 0 4 android:theme="@style/AppTheme" > 1 4 2 4 android:name="ivit3 y" 4 android:label="@string/app_name" > 4 4 5 4 6 /> 47 4 4 9 5 0 51 52 5 54 android:process=":remote"> 5 7 5 8 5 6

界面只有一个mapview地图控件，在此列出activity_：
01
0 0 android:layout_width="fill_parent" 3 0 android:layout_height="fill_parent" 4 0 android:orientation="vertical" 5 0 > 6 0 7 0 8 0 android:layout_width="fill_parent" 9 1 android:layout_height="fill_parent" 0 1 android:clickable="true" /> 1 1 > 2 1 3 1
