最简洁的广播和广播接收器，纯代码形式
这个东西用于通信还是比较方便的，呵呵，那就来个最简洁的吧：
?
发送端，即Broadcast:
?
private String BROADCAST_ACTION_SEARCH_PROCESS = "dingran.SearchProcess";
?
Intent intent = new Intent();
intent.setAction(BROADCAST_ACTION_SEARCH_PROCESS);
// 把需要传递的数据放到intent里
this.sendBroadcast(intent);
?
接收端，即BroadcastReceiver:
?
private String BROADCAST_ACTION_SEARCH_PROCESS = "dingran.SearchProcess";
?
private MyBroadCastReceiver mbcr = new MyBroadCastReceiver();
?
private class MyBroadCastReceiver extends BroadcastReceiver{
??????? @Override
??????? public void onReceive(Context context, Intent intent) {
????????? // 这里就可以接收intent了，解析你需要的数据
??? }
}
?
接收端需要注册，我们从代码注册方便，就从onCreat里吧：
?
IntentFilter inf = new IntentFilter();
inf.addAction(BROADCAST_ACTION_SEARCH_PROCESS);
this.registerReceiver(mbcr, inf);
?
