android 有序广播 如何终止,Android-有序广播是可以中断的

在之前的博客，Android-广播概念，中介绍了(广播和广播接收者)可以组件与组件之间进行通讯，有两种类型的广播(无序广播 和 有序广播)，这篇博客就来讲解有序广播的代码实现：

有序广播：接收者可以自己设置接受的顺序，所以叫有序广播

有序广播是可以中断的，而指定某个接收者的有序广播是无法中断的

在AndroidManifest.xml订阅 两个接收者

定义 MyBroadcastReceiver1 接收者

packageliudeli.croadcast1.br;importandroid.content.BroadcastReceiver;importandroid.content.Context;importandroid.content.Intent;importandroid.util.Log;/*** 定义 接收者*/

public class MyBroadcastReceiver1 extendsBroadcastReceiver {private final String TAG = "MyBroadcastReceiver";/*** 接收的方法

*@paramcontext 传递过来的上下文

*@paramintent 传递过来的意图，可以获取很多信息*/@Overridepublic voidonReceive(Context context, Intent intent) {

Log.d(TAG,"【1111111111】intent.getAction():" +intent.getAction());

Log.d(TAG,"【1111111111】intent.getDataString():" +intent.getDataString());//真实开发中是这样写的

if ("my.MyBroadcastReceiver.custom.action2".equals(intent.getAction())) {

String data=intent.getDataString();

String[] dataArray= data.split(":");

Log.d(TAG,"【1111111111】data:" + dataArray[1]);

Log.d(TAG,"【1111111111】music:" + intent.getStringExtra("music"));

}else if ("xxx.action".equals(intent.getAction())) {//做相应的业务逻辑处理//...

} else if ("xxx.action".equals(intent.getAction())) {//做相应的业务逻辑处理//...

}

}

}

定义 MyBroadcastReceiver2 接收者

packageliudeli.croadcast1.br;importandroid.content.BroadcastReceiver;importandroid.content.Context;importandroid.content.Intent;importandroid.util.Log;/*** 定义 接收者*/

public class MyBroadcastReceiver2 extendsBroadcastReceiver {private final String TAG = "MyBroadcastReceiver";/*** 接收的方法

*@paramcontext 传递过来的上下文

*@paramintent 传递过来的意图，可以获取很多信息*/@Overridepublic voidonReceive(Context context, Intent intent) {

Log.d(TAG,"【222222222】intent.getAction():" +intent.getAction());

Log.d(TAG,"【222222222】intent.getDataString():" +intent.getDataString());//真实开发中是这样写的

if ("my.MyBroadcastReceiver.custom.action2".equals(intent.getAction())) {

String data=intent.getDataString();

String[] dataArray= data.split(":");

Log.d(TAG,"【222222222】data:" + dataArray[1]);

Log.d(TAG,"【222222222】music:" + intent.getStringExtra("music"));

}else if ("xxx.action".equals(intent.getAction())) {//做相应的业务逻辑处理//...

} else if ("xxx.action".equals(intent.getAction())) {//做相应的业务逻辑处理//...

}

}

}

发送有序广播send：

/*** 发送有序广播*/

public voidsendOrderBroadcast(View view) {/*** 两个接收者在AndroidManifest.xml是这样订阅的：怎么订阅，就怎么发送

*

*

*

*

*

*

* */Intent intent= newIntent();

intent.setAction("my.MyBroadcastReceiver.custom.action");

intent.setData(Uri.parse("OOO:四环奥迪，五环奥运")); //注意：要加 :

intent.putExtra("music", "奥林匹克风歌曲"); //而外携带值//参数一：意图 参数二：谁能接收我的广播(自定义权限)

sendOrderedBroadcast(intent, null);

}

没在 MyBroadcastReceiver2 加入中断的日志

12-17 08:49:52.885 4872-4872/liudeli.croadcast1 D/MyBroadcastReceiver: 【222222222】intent.getAction():my.MyBroadcastReceiver.custom.action

12-17 08:49:52.885 4872-4872/liudeli.croadcast1 D/MyBroadcastReceiver: 【222222222】intent.getDataString():OOO:四环奥迪，五环奥运

12-17 08:49:52.887 4872-4872/liudeli.croadcast1 D/MyBroadcastReceiver: 【1111111111】intent.getAction():my.MyBroadcastReceiver.custom.action

由于MyBroadcastReceiver2 接收者，优先接受到信息，所以在 MyBroadcastReceiver2中断广播，abortBroadcast();

packageliudeli.croadcast1.br;importandroid.content.BroadcastReceiver;importandroid.content.Context;importandroid.content.Intent;importandroid.util.Log;/*** 定义 接收者*/

public class MyBroadcastReceiver2 extendsBroadcastReceiver {private final String TAG = "MyBroadcastReceiver";/*** 接收的方法

*@paramcontext 传递过来的上下文

*@paramintent 传递过来的意图，可以获取很多信息*/@Overridepublic voidonReceive(Context context, Intent intent) {/*** 中断广播*/abortBroadcast();

Log.d(TAG,"【222222222】intent.getAction():" +intent.getAction());

Log.d(TAG,"【222222222】intent.getDataString():" +intent.getDataString());//真实开发中是这样写的

if ("my.MyBroadcastReceiver.custom.action2".equals(intent.getAction())) {

String data=intent.getDataString();

String[] dataArray= data.split(":");

Log.d(TAG,"【222222222】data:" + dataArray[1]);

Log.d(TAG,"【222222222】music:" + intent.getStringExtra("music"));

}else if ("xxx.action".equals(intent.getAction())) {//做相应的业务逻辑处理//...

} else if ("xxx.action".equals(intent.getAction())) {//做相应的业务逻辑处理//...

}

}

}

在 MyBroadcastReceiver2 加入中断的日志
