在fragment中使用百度地圖

【寫在前面的話：關於你們的說的下載要10個e幣的問題，我不知道怎麼能夠設置成任意數目（汗……），若是有須要的但e幣不夠的朋友，能夠留下郵箱，我抽空給大家發過去（2013-12-23 19:08）】  - - - - - - - - - - - - - - -- - - - - - - - - - - - - 分 - - - - - 割 - - - - - 線- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -  使用最新版本的百度地圖須要注意的幾個地方： 一、libs文件夾下要有android-support-v4.jar、baidumapapi_v2_1_0.jar、locSDK_3.1.jar三個jar包和armeabi文件夾。詳見下圖：   二、佈局文件要寫成<com.baidu.mapapi.map.MapView />，舊版本是寫做<com.baidu.mapapi.MapView />的。 三、AndroidMainfest這個配置文件要把該添加的東西都加上。好比各類權限、好比屏幕支持、好比百度地圖服務 <service        android:name="com.baidu.location.f"                      android:enabled="true"                                            android:process=":remote"> </service> 等 四、不要忘了申請本身的密鑰。 ……時間有限，就寫這麼多吧，遇到問題就百度一下，基本上也就解決了。 噢，附上本身的demo和各個連接。 百度地圖API>Android SDK>相關下載  sdk下載  （http://developer.baidu.com/map/sdkandev-download.htm ） 百度地圖API>Android SDK>申請Key  申請key的連接  （http://developer.baidu.com/map/android-mobile-apply-key.htm） 百度地圖API>定位 SDK>Android 定位SDK> 定位sdk的連接 （http://developer.baidu.com/map/geosdk-android-download.htm） 對了，還有效果圖     - - - - - - - - - - -- - - - - - - - - - -分 割 線 -- - - - - - - - - - - -- - - - - - - - - - - -- - - - - - - - - - - -- - - - - - - - - - - - 【補充—2013-12-10 18:48】 一、代碼結構：      二、各個類的大體做用：     (1) Cheeses.java  填充沒有用到的Fragment的內容     (2) DemoApplication.java  從百度地圖sdk demo中直接拿來的；主要用來處理與key相關的操做     (3) MainActivity.java  實現適配器，完成不一樣Fragment之間的切換     (4) MapFragment.java  定位相關的操做 三、附上主要類的源碼：     (1) MainActivity.java 代碼片斷，雙擊複製 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 import android.os.Bundle;
