Android百度地图之Poi搜索功能

该示例主要介绍关键词查询、suggestion查询和查看餐饮类Place详情页功能，尤其搜索某个地方的餐厅、理发店等等比较有实际意义，百度Demo代码如下：

Activity：

布局XML（activity_poisearch）：

<?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" >        <LinearLayout          android:layout_width="fill_parent"          android:layout_height="50dip"          android:orientation="horizontal" >            <TextView              android:layout_width="wrap_content"              android:layout_height="wrap_content"              android:text="在" >          </TextView>            <EditText              android:id="@+id/city"              android:layout_width="wrap_content"              android:layout_height="match_parent"              android:text="北京" />            <TextView              android:layout_width="wrap_content"              android:layout_height="wrap_content"              android:text="市内找" >          </TextView>            <AutoCompleteTextView              android:id="@+id/searchkey"              android:layout_width="wrap_content"              android:layout_height="wrap_content"              android:layout_weight="0.88"              android:text="餐厅" />      </LinearLayout>        <LinearLayout          android:layout_width="fill_parent"          android:layout_height="50dip"          android:orientation="horizontal" >            <Button              android:id="@+id/search"              android:layout_width="fill_parent"              android:layout_height="wrap_content"              android:layout_weight="12"              android:background="@drawable/button_style"              android:onClick="searchButtonProcess"              android:padding="10dip"              android:text="开始" />            <Button              android:id="@+id/map_next_data"              android:layout_width="fill_parent"              android:layout_height="wrap_content"              android:layout_weight="12"              android:background="@drawable/button_style"              android:onClick="goToNextPage"              android:padding="10dip"              android:text="下一组数据" />      </LinearLayout>        <com.baidu.mapapi.map.MapView          android:id="@+id/bmapView"          android:layout_width="fill_parent"          android:layout_height="fill_parent"          android:clickable="true" />    </LinearLayout>

MyPoiOverlay类：

package com.home;    import android.app.Activity;    import com.baidu.mapapi.map.MapView;  import com.baidu.mapapi.map.PoiOverlay;  import com.baidu.mapapi.search.MKPoiInfo;  import com.baidu.mapapi.search.MKSearch;    public class MyPoiOverlay extends PoiOverlay {     MKSearch mSearch;     public MyPoiOverlay(Activity activity, MapView mapView, MKSearch search) {    super(activity, mapView);    mSearch = search;   }     @Override   protected boolean onTap(int i) {    super.onTap(i);    MKPoiInfo info = getPoi(i);    if (info.hasCaterDetails) {     mSearch.poiDetailSearch(info.uid);    }    return true;   }    }

在配置文件中要比之前多配置一个activity，不然没法查看详细界面，这是百度SDK jar中提供的类：

       <activity              android:name="com.baidu.mapapi.search.PlaceCaterActivity"              android:configChanges="orientation|keyboardHidden"              android:theme="@android:style/Theme.NoTitleBar" >          </activity>

Application类同之前。

附上图片效果：
