news 来源：原创 2024/5/7 8:03:18

基于Fragment的百度Map也很简单

直接看例子吧：

AndroidManifest.xml的配置：

 1 <?xml version="1.0" encoding="utf-8"?>
 2 <manifest xmlns:android="http://schemas.android.com/apk/res/android"
 3     package="com.example.testbaidu_v_3_1"
 4     android:versionCode="1"
 5     android:versionName="1.0" >
 6 
 7     <uses-sdk
 8         android:minSdkVersion="8"
 9         android:targetSdkVersion="21" />
10 
11     <uses-permission android:name="android.permission.GET_ACCOUNTS" />
12     <uses-permission android:name="android.permission.USE_CREDENTIALS" />
13     <uses-permission android:name="android.permission.MANAGE_ACCOUNTS" />
14     <uses-permission android:name="android.permission.AUTHENTICATE_ACCOUNTS" />
15     <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
16     <uses-permission android:name="android.permission.INTERNET" />
17     <uses-permission android:name="com.android.launcher.permission.READ_SETTINGS" />
18     <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
19     <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
20     <uses-permission android:name="android.permission.READ_PHONE_STATE" />
21     <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
22     <uses-permission android:name="android.permission.BROADCAST_STICKY" />
23     <uses-permission android:name="android.permission.WRITE_SETTINGS" />
24     <uses-permission android:name="android.permission.READ_PHONE_STATE" />
25 
26     <application
27         android:allowBackup="true"
28         android:icon="@drawable/ic_launcher"
29         android:label="@string/app_name"
30         android:theme="@style/AppTheme" >
31         <meta-data
32             android:name="com.baidu.lbsapi.API_KEY"
33             android:value="your key" />
34         
35         <activity
36             android:name=".MapFragment"
37             android:label="@string/app_name" >
38             <intent-filter>
39                 <action android:name="android.intent.action.MAIN" />
40 
41                 <category android:name="android.intent.category.LAUNCHER" />
42             </intent-filter>
43         </activity>
44     </application>
45 
46 </manifest>

MapFragment类：

28         setContentView(R.layout.activity_fragment);
29         MapStatus ms = new MapStatus.Builder().overlook(-20).zoom(15).build();

48         super.onDestroy();
49         // 在activity执行onDestroy时执行mMapView.onDestroy()，实现地图生命周期管理
50         unregisterReceiver(mReceiver);
51     }
52     
53     public class SDKReceiver extends BroadcastReceiver {
54         public void onReceive(Context context, Intent intent) {
55             String s = intent.getAction();
56             if (s.equals(SDKInitializer.SDK_BROADTCAST_ACTION_STRING_PERMISSION_CHECK_ERROR)) {
57                 Toast.makeText(MapFragment.this,
58                         "key 验证出错! 请在 AndroidManifest.xml 文件中检查 key 设置",
59                         Toast.LENGTH_SHORT).show();
60                 ;
61             } else if (s

65             }
66         }
67     }
68 }
