Android手机开发：Intent和Broadcast

Android手机开发：Intent和Broadcast

1. 构造Intent，发送广播

1. static final String ACTION_1 = "com.eoeAndroid.action.NEW_BROADCAST_1";  
2. Intent intent = new Intent(ACTION_1);  
3. sendBroadcast(intent);  

2. 继承BroadcastReceiver类，实现一个广播接受类

1. public class EoeAndroidReceiver extends BroadcastReceiver {  
2.     Context context;  
3.   
4.     @Override  
5.     public void onReceive(Context context, Intent intent) {  
6.         // TODO Auto-generated method stub   
7.         this.context = context;  
8.         //接受信息并处理   
9.     }  
10. }  

3. 注册和注销BroadcastReceiver

方法1：在AndroidManifest.xml中注册

1. <receiver android:name="EoeAndroidReceiver1">  
2.     <intent-filter>  
3.         <action  
4.             android:name="com.eoeandroid.action.NEW_BROADCAST_1"/>  
5.     </intent-filter>  
6. </receiver>  

方法2：直接在代码中注册

1. IntentFilter filter = new IntentFilter(NEW_BROADCAST);  
2. EoeAndroidReceiver eoeAR = new EoeAndroidReceiver();  
3. registerReceiver(eoeAR, filter);  

注销

1. unregisterReceiver(eoeAR);
