1、第一步：項目中添加lib文件夾，放入百度相關jar包，如下圖

第二步：編寫布局文件

<?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" ><FrameLayoutandroid:layout_width="fill_parent"android:layout_height="0dip"android:layout_weight="1"android:background="#FFFF00" ><LinearLayoutandroid:id="@+id/yqxx_table_title"android:layout_width="match_parent"android:layout_height="match_parent"android:background="#FFFF00"android:orientation="vertical" ><WebViewandroid:id="@+id/webview"android:layout_width="fill_parent"android:layout_height="fill_parent"android:background="@drawable/back" /></LinearLayout><com.baidu.mapapi.map.MapViewandroid:id="@+id/bmapView"android:layout_width="fill_parent"android:layout_height="fill_parent"android:clickable="true" /></FrameLayout><LinearLayoutandroid:layout_width="match_parent"android:layout_height="55dp"android:orientation="horizontal" ><Buttonandroid: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" /><Buttonandroid: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：編寫Acvity程序
