百度地图3.1.0(一)Hello BaiduMap

1：在工程里新建libs文件夹，将开发包里的baidumapapi_vX_X_X.jar拷贝到libs根目录下，将libBaiduMapSDK_vX_X_X.so拷贝到libs\armeabi目录下

如图所示：

 

2：在AndroidManifest中添加开发密钥、所需权限等信息

1 <application  

2     <meta-data  

3         android:name="com.baidu.lbsapi.API_KEY"  

4         android:value="开发者 key" />  

5 </application>

 1 <uses-permission android:name="android.permission.GET_ACCOUNTS" />  

 2 <uses-permission android:name="android.permission.USE_CREDENTIALS" />  

 3 <uses-permission android:name="android.permission.MANAGE_ACCOUNTS" />  

 4 <uses-permission android:name="android.permission.AUTHENTICATE_ACCOUNTS" />  

 5 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />  

 6 <uses-permission android:name="android.permission.INTERNET" />  

 7 <uses-permission android:name="com.android.launcher.permission.READ_SETTINGS" />  

 8 <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />  

 9 <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />  

10 <uses-permission android:name="android.permission.READ_PHONE_STATE" />  

11 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />  

12 <uses-permission android:name="android.permission.BROADCAST_STICKY" />  

13 <uses-permission android:name="android.permission.WRITE_SETTINGS" />  

14 <uses-permission android:name="android.permission.READ_PHONE_STATE" />

3：在布局xml文件中添加地图控件

1 <com.baidu.mapapi.map.MapView  

2     android:id="@+id/bmapView"  

3     android:layout_width="fill_parent"  

4     android:layout_height="fill_parent"  

5     android:clickable="true" />

4：在应用程序创建时初始化 SDK引用的Context 全局变量

 1 public class MainActivity extends Activity {  

 2     @Override  

 3     protected void onCreate(Bundle savedInstanceState) {  

 4         super.onCreate(savedInstanceState);   

 5         //在使用SDK各组件之前初始化context信息，传入ApplicationContext  

 6         //注意该方法要再setContentView方法之前实现  

 7         SDKInitializer.initialize(getApplicationContext());  

 8         setContentView(R.layout.activity_main);  

 9     }  

10 }

//在SDK各功能组件使用之前都需要调用SDKInitializer.initialize(getApplicationContext());，百度建议该方法放在Application的初始化方法中

5：创建地图Activity，管理地图生命周期

 1 package com.example.testbaidu_v_3_1;

 2 

 3 import android.content.BroadcastReceiver;

 4 import android.content.Context;

 5 import android.content.Intent;

 6 import android.content.IntentFilter;

 7 import android.os.Bundle;

 8 import android.support.v7.app.ActionBarActivity;

 9 import android.widget.Toast;

10 

11 import com.baidu.mapapi.SDKInitializer;

12 import com.baidu.mapapi.map.MapView;

13 

14 public class MainActivity extends ActionBarActivity {

15 

16     private MapView mMapView = null;

17     private SDKReceiver mReceiver;

18 

19     protected void onCreate(Bundle savedInstanceState) {

20         super.onCreate(savedInstanceState);

21         // 在使用SDK各组件之前初始化context信息，传入ApplicationContext

22         // 注意该方法要再setContentView方法之前实现

23         SDKInitializer.initialize(getApplicationContext());

24         setContentView(R.layout.activity_main);

25         // 获取地图控件引用

26         mMapView = (MapView) findViewById(R.id.bmapView);

27 

28         //看baidu的Demo，发现它注册这个广播，用来监听SDKInitializer的初始化

29         IntentFilter iFilter = new IntentFilter();

30         iFilter.addAction(SDKInitializer.SDK_BROADTCAST_ACTION_STRING_PERMISSION_CHECK_ERROR);

31         iFilter.addAction(SDKInitializer.SDK_BROADCAST_ACTION_STRING_NETWORK_ERROR);

32         mReceiver = new SDKReceiver();

33         registerReceiver(mReceiver, iFilter);

34     }

35 

36     protected void onDestroy() {

37         super.onDestroy();

38         // 在activity执行onDestroy时执行mMapView.onDestroy()，实现地图生命周期管理

39         mMapView.onDestroy();

40         unregisterReceiver(mReceiver);

41     }

42 

43     @Override

44     protected void onResume() {

45         super.onResume();

46         // 在activity执行onResume时执行mMapView. onResume ()，实现地图生命周期管理

47         mMapView.onResume();

48     }

49 

50     @Override

51     protected void onPause() {

52         super.onPause();

53         // 在activity执行onPause时执行mMapView. onPause ()，实现地图生命周期管理

54         mMapView.onPause();

55     }

56 

57     public class SDKReceiver extends BroadcastReceiver {

58         public void onReceive(Context context, Intent intent) {

59             String s = intent.getAction();

60             if (s.equals(SDKInitializer.SDK_BROADTCAST_ACTION_STRING_PERMISSION_CHECK_ERROR)) {

61                 Toast.makeText(MainActivity.this,

62                         "key 验证出错! 请在 AndroidManifest.xml 文件中检查 key 设置",

63                         Toast.LENGTH_SHORT).show();

64                 ;

65             } else if (s

66                     .equals(SDKInitializer.SDK_BROADCAST_ACTION_STRING_NETWORK_ERROR)) {

67                 Toast.makeText(MainActivity.this, "网络出错", Toast.LENGTH_SHORT)

68                         .show();

69             }

70         }

71     }

72 

73 }

运行程序，即可在您的应用中显示如下地图
