本文主要包括百度地圖API的綜合應用，主要內容如下

地圖圖層展示，包括熱力圖與實時路況圖

添加覆蓋物，包括圖片，文字，折線等

地圖控制，包括俯視，旋轉，放大，縮小等

定位，并且用圖標標示出來

POI檢索，檢索出范圍內的興趣點

公交線路查詢

路線規劃，包括駕車，公交，步行。

主界面

package com.zj.mapall;import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.widget.AdapterView; import android.widget.AdapterView.OnItemClickListener; import android.widget.ArrayAdapter; import android.widget.ListView;/*** 程序啟動引導頁，選擇不同的功能進入不同的界面* * @author ys**/ public class LaunchActivity extends Activity {private ListView listview;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_launch);listview = (ListView) findViewById(R.id.activity_listview);init();}/*** 初始化listview列表*/private void init() {final Class[] clazz = { BasisMapActivity.class,AddOverlayActivity.class, MapControllActivity.class,LocationActivity.class,PoiSearchActivity.class,BusLineSearchActivity.class,RoutePlanningActivity.class};String arr[] = { "地圖圖層展示" ,"添加覆蓋物" ,"地圖控制 ","定位","POI檢索","公交線路查詢","路線規劃"};ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, arr);listview.setAdapter(adapter);listview.setOnItemClickListener(new OnItemClickListener() {@Overridepublic void onItemClick(AdapterView<?> parent, View view,int position, long id) {startActivity(new Intent(LaunchActivity.this, clazz[position]));}});} }

注意，加載地圖前應初始化SDKInitializer，可放在Application中初始化

package com.zj.mapall;import com.baidu.mapapi.SDKInitializer;import android.app.Application;public class MyApplication extends Application{@Overridepublic void onCreate() {// TODO Auto-generated method stubsuper.onCreate();SDKInitializer.initialize(getApplicationContext());}}
