依賴包類:
傳送廣播,實現例項如下:
if((nitscan == 1) && (chnum > 0))
else
}break;
default:
broadcast_cmd = "";
broadcast_param = "";
break;
}intent.putextra(dvb_channel_search_broadcast_extr_cmd, broadcast_cmd);
intent.putextra(dvb_channel_search_broadcast_extr_param, broadcast_param);
log.i(tag, "channelscanimpl send broadcast:" + broadcast_cmd + "\n");
this.sendbroadcast(intent);
}接收廣播的方法:
private
broadcastreceiver mbroadcastreceiver = null;
mbroadcastreceiver = new epgdbimplintentreceiver();
intentfilter intentfilter = new intentfilter();
intentfilter.addaction(dvbbase.dvb_channel_search_broadcast_action);
mcontext.registerreceiver(mbroadcastreceiver, intentfilter);
private
class channeldbimplintentreceiver extends broadcastreceiver
else if (objects.equals(msg, dvb_channel_search_broadcast_msg_finish)) }}
} 另外一種接收方法:在androidmanifest.xml中宣告,而不需要在context中registerreceiver,宣告如下:
結束:mcontext.unregisterreceiver(mbroadcastreceiver);
備註:因為廣播方式傳遞訊息和引數,延時太長,不宜用於快速反應的應用!
Android中的廣播
android中的廣播。有發射廣播,必須要有收音機才能接到,並且調對臺才能得到對應的臺。1.電台發射廣播 使用intent,intent intent new intent 需要廣播的臺的名字 context。sendbroadcast intent 也就是先 生成一下你需要廣播的臺,然後用send...

android 廣播的使用
1.broadcastreceive,廣播,android四大元件之一,顧名思義,只要發出了這個廣播,在這個頻率上就可以接受到這個廣播。2.廣播主要用於訊息通訊,可以用於不同的元件,不同的頁面,只要一方發出一方接收,就可以得到廣播,獲取資訊。廣播類屬於觀察者模式,極大程度的解耦了程式,只需要在一處發...
