Android百度地圖poi範圍搜尋_Android

我想大家可能都有過這樣的經曆：兜裡揣著一張銀行卡，在街上到處找自動取款機（ATM）。在這個情境中，ATM就是的興趣點，我們想做的事情就是找到離自己較近的一些ATM然後取款，此時我們並不關心附近有哪些超市、酒吧，因為這些地方沒辦法取錢！

說了這麼多，一方面是加深大家對POI這個詞的認識，另一方面也是為了讓大家明白我們接下來要做的事情。理論性的東西就不再多講了，直接來看例子。

先給大家展示下效果圖：

詳細介面：

該樣本主要介紹關鍵詞查詢、suggestion查詢和查看餐飲類Place詳情頁功能，尤其搜尋某個地方的餐廳、理髮店等等比較有實際意義，百度Demo代碼如下：

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" ><LinearLayoutandroid:layout_width="fill_parent"android:layout_height="50dip"android:orientation="horizontal" ><TextViewandroid:layout_width="wrap_content"android:layout_height="wrap_content"android:text="在" ></TextView><EditTextandroid:id="@+id/city"android:layout_width="wrap_content"android:layout_height="match_parent"android:text="北京" /><TextViewandroid:layout_width="wrap_content"android:layout_height="wrap_content"android:text="市內找" ></TextView><AutoCompleteTextViewandroid:id="@+id/searchkey"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_weight="0.88"android:text="餐廳" /></LinearLayout><LinearLayoutandroid:layout_width="fill_parent"android:layout_height="50dip"android:orientation="horizontal" ><Buttonandroid: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="開始" /><Buttonandroid: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="下一組資料" /></LinearLayout><com.baidu.mapapi.map.MapViewandroid:id="@+id/bmapView"android:layout_width="fill_parent"android:layout_height="fill_parent"android:clickable="true" /></LinearLayout>

MyPoiOverlay類

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;}@Overrideprotected boolean onTap(int i) {super.onTap(i);MKPoiInfo info = getPoi(i);if (info.hasCaterDetails) {mSearch.poiDetailSearch(info.uid);}return true;}}

在設定檔中要比之前多配置一個activity，不然沒法查看詳細介面，這是百度SDK jar中提供的類：

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

Application類同之前。
