简单的实现自定义广播(Broadcast)机制

首先在ManiFset文件当中定义一个Receiver，并设置intent-filter

例如：


<receiver android:name=".SendDownXMLBroadCast">
 <intent-filter > 
<!--自定义广播-->
 <action android:name="com.neter.broadcast.receiver.SendDownXMLBroadCast"/>
 </intent-filter> </receiver>

接下来就是在activity当中设置自定义的广播，如下：


Intent intent = new Intent();
 intent.setAction("com.neter.broadcast.receiver.SendDownXMLBroadCast");//发出自定义广播
 context.sendBroadcast(intent);

最后就是广播接收器的实现：


public class SendDownXMLBroadCast extends BroadcastReceiver {
 public void onReceive(Context context, Intent intent) {
 System.out.println("send BroadCast seccess!");
 Intent intent2=new Intent(context, DownFriendXML.class);
 context.startService(intent2);
 } }
