(一)基本介紹(Fragment和SupportMapFragment):

? ? ? Fragment的使用現(xiàn)在安卓APP開發(fā)中用的比較多了，Fragment名稱為碎片和Activity有著相似的生命管理周期，基本作用可以進(jìn)行開發(fā)兼容手機(jī)和平板的app,較少兼容分辨率版本的工作量，提高工作效率。其中Fragment還是可以包含控制代碼的視圖模塊，可以非常方便的進(jìn)行組合。使用起來很方便。具體有個(gè)Fragment的介紹和使用請(qǐng)點(diǎn)擊查看(官網(wǎng)Fragment的介紹和基本使用)，這邊就不多講了。下面我們來看下百度地圖API給我們提供的地圖框架SupportMapFragment。SupportMapFragment是繼承于Fragment因此具備Fragment的完成的生命周期,該框架主要用來管理地圖生命周期,主要有下面兩個(gè)方法1:getMapView()：獲取MapView引用，要在onCreateView函數(shù)調(diào)用之后進(jìn)行使用.2:newInstance();返回獲取SupportMapFragment對(duì)象實(shí)例。

(二)使用方法:?

? ? ?使用方法和我們平時(shí)用Fragment的時(shí)候差不多,首先獲取SupportMapFragment實(shí)例，然后把該Fragment添加到指定View視圖圖.commit一下即可.

(三)代碼演示，注釋基本已經(jīng)寫了挺詳細(xì)了，直接看就OK了

? ? ?1.自定義MyApplication.java設(shè)置全局變量,并且進(jìn)行校驗(yàn)密鑰:

package com.ztt.baidumap.ui;import android.app.Application; import android.content.Context; import android.util.Log; import android.widget.Toast;import com.baidu.mapapi.BMapManager; import com.baidu.mapapi.MKGeneralListener; import com.baidu.mapapi.map.MKEvent; /*** 自定義Application,進(jìn)行key識(shí)別驗(yàn)證 （使用單例）* @author Jiangqq* @time 2014/03/15 10:14*/ public class MyApplication extends Application {public static MyApplication instance=null;BMapManager mBMapManager = null;public boolean m_bKeyRight = true;public static final String strKey = "vUAGbPwLpolIqiwWisnQPeIE"; //百度地圖官網(wǎng)申請(qǐng)的密鑰public static MyApplication getInstance(){return instance;}@Overridepublic void onCreate() {super.onCreate();instance=this;//在APP應(yīng)用啟動(dòng)的時(shí)候，進(jìn)行初始化驗(yàn)證initEngineManager(this);}/*** 進(jìn)行驗(yàn)證key* @param pContext*/private void initEngineManager(Context pContext){if (mBMapManager == null) {mBMapManager = new BMapManager(pContext);}if (!mBMapManager.init(strKey,new MyGeneralListener())) {Toast.makeText(MyApplication.getInstance(), "BMapManager 初始化錯(cuò)誤!", Toast.LENGTH_LONG).show();}}// 常用事件監(jiān)聽，用來處理通常的網(wǎng)絡(luò)錯(cuò)誤，授權(quán)驗(yàn)證錯(cuò)誤等static class MyGeneralListener implements MKGeneralListener {@Overridepublic void onGetNetworkState(int iError) {if (iError == MKEvent.ERROR_NETWORK_CONNECT) {Toast.makeText(MyApplication.getInstance(), "您的網(wǎng)絡(luò)出錯(cuò)啦！",Toast.LENGTH_LONG).show();}else if (iError == MKEvent.ERROR_NETWORK_DATA) {Toast.makeText(MyApplication.getInstance(), "輸入正確的檢索條件！",Toast.LENGTH_LONG).show();}else {Log.d("zttjiangqq", "iError="+iError);}// ... }@Overridepublic void onGetPermissionState(int iError) {//非零值表示key驗(yàn)證未通過if (iError != 0) {//授權(quán)Key錯(cuò)誤： Toast.makeText(MyApplication.getInstance(), "請(qǐng)?jiān)?DemoApplication.java文件輸入正確的授權(quán)Key,并檢查您的網(wǎng)絡(luò)連接是否正常！error: "+iError, Toast.LENGTH_LONG).show();MyApplication.getInstance().m_bKeyRight = false;}else{MyApplication.getInstance().m_bKeyRight = true;Toast.makeText(MyApplication.getInstance(), "key認(rèn)證成功", Toast.LENGTH_LONG).show();}}} }

　　?2:創(chuàng)建一個(gè)FragmentMapDemo.java,繼承于FragmentActivity，使用newInstance()方法獲取SupportMapFragment,進(jìn)行顯示地圖:

package com.ztt.baidumap.ui;import android.content.res.Configuration; import android.os.Bundle; import android.support.v4.app.FragmentActivity; import android.support.v4.app.FragmentManager; import android.support.v4.app.FragmentTransaction; import android.util.Log;import com.baidu.mapapi.BMapManager; import com.baidu.mapapi.map.MapController; import com.baidu.mapapi.map.SupportMapFragment; import com.baidu.platform.comapi.basestruct.GeoPoint;public class FragmentMapDemo extends FragmentActivity {SupportMapFragment map;@Overridepublic void onCreate(Bundle arg0) {/*** 使用地圖sdk前需先初始化BMapManager.* BMapManager是全局的，可為多個(gè)MapView共用，它需要地圖模塊創(chuàng)建前創(chuàng)建，* 并在地圖地圖模塊銷毀后銷毀，只要還有地圖模塊在使用，BMapManager就不應(yīng)該銷毀*/MyApplication app = (MyApplication)this.getApplication();if (app.mBMapManager == null) {app.mBMapManager = new BMapManager(getApplicationContext());/*** 如果BMapManager沒有初始化則初始化BMapManager*/app.mBMapManager.init(MyApplication.strKey,new MyApplication.MyGeneralListener());}Log.d("zttjiangqq", "onCreate");setContentView(R.layout.activity_fragment);map = SupportMapFragment.newInstance();FragmentManager manager = getSupportFragmentManager();FragmentTransaction ft= manager.beginTransaction();ft.add(R.id.map, map, "map_fragment");ft.commit();}@Overrideprotected void onRestoreInstanceState(Bundle savedInstanceState) {super.onRestoreInstanceState(savedInstanceState);Log.d("zttjiangqq", "onRestoreInstanceState");}@Overrideprotected void onRestart() {super.onRestart();Log.d("zttjiangqq", "onRestart");}@Overridepublic void onStart() {super.onStart();Log.d("zttjiangqq", "onStart");}@Overridepublic void onResume() {super.onResume();Log.d("zttjiangqq", "onResume");// 得到MapView的控制權(quán),可以用它控制和驅(qū)動(dòng)平移和縮放 MapController controller = map.getMapView().getController();// 用給定的經(jīng)緯度構(gòu)造一個(gè)GeoPoint，單位是微度 (度 * 1E6) 并且設(shè)置設(shè)置地圖中心點(diǎn) (這邊使用天安門)controller.setCenter(new GeoPoint((int)(39.945 * 1E6), (int)(116.404 * 1E6)));// 設(shè)置地圖zoom級(jí)別 controller.setZoom(13);}@Overridepublic void onSaveInstanceState(Bundle outState) {super.onSaveInstanceState(outState);Log.d("zttjiangqq", "onSaveInstanceState");}@Overridepublic void onPause() {super.onPause();Log.d("zttjiangqq", "onPause");}@Overridepublic void onStop() {super.onStop();Log.d("zttjiangqq", "onStop");}@Overridepublic void onDestroy() {super.onDestroy();Log.d("zttjiangqq", "onDestory");}@Overridepublic void onConfigurationChanged(Configuration newConfig) {super.onConfigurationChanged(newConfig);Log.d("zttjiangqq", "onConfigurationChanged");} }

　　3: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:orientation="vertical" ><FrameLayoutandroid:id="@+id/map"android:layout_width="match_parent"android:layout_height="match_parent" /></LinearLayout>

　　(三)注意一定要添加配置權(quán)限

<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" /><uses-permission android:name="android.permission.BAIDU_LOCATION_SERVICE" /><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /><uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /><uses-permission android:name="android.permission.INTERNET" /><uses-permission android:name="android.permission.ACCES_MOCK_LOCATION" /><uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /><uses-permission android:name="com.android.launcher.permission.READ_SETTINGS" /><uses-permission android:name="android.permission.WAKE_LOCK" /><uses-permission android:name="android.permission.CHANGE_WIFI_STATE" /><uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /><uses-permission android:name="android.permission.ACCESS_GPS" /><!-- SDK1.5需要android.permission.GET_TASKS權(quán)限判斷本程序是否為當(dāng)前運(yùn)行的應(yīng)用? --><uses-permission android:name="android.permission.GET_TASKS" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /><uses-permission android:name="android.permission.BROADCAST_STICKY" /><uses-permission android:name="android.permission.WRITE_SETTINGS" /><!-- 來電消音 --><uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" /><uses-permission android:name="android.permission.READ_PHONE_STATE" /><uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" /><uses-permission android:name="android.permission.RECORD_AUDIO" />
