1、第一步：项目中添加lib文件夹，放入百度相关jar包，如下图
第二步：编写布局文件
<?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:background="@drawable/back"
android:orientation="vertical" >
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="0dip"
android:layout_weight="1"
android:background="#FFFF00" >
<LinearLayout
android:id="@+id/yqxx_table_title"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FFFF00"
android:orientation="vertical" >
<WebView
android:id="@+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/back" />
</LinearLayout>
<com.baidu.mapapi.map.MapView
android:id="@+id/bmapView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="true" />
</FrameLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="55dp"
android:orientation="horizontal" >
<Button
android:id="@+id/yqxx_List_Button"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:background="@drawable/yq_list_up" />
<Button
android:id="@+id/yqxx_Map_Button"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:background="@drawable/yq_map_down" />
</LinearLayout>
</LinearLayout>
第三步：编写Acvity程序
