Android(安卓)BroadcastReceiver小结

该组件分为2种

一种是无顺序异步的只要一发广告所有能接收到服务的应用都能同时收到。

发送：

sendBroadcast(intent);

接收

public class MyRecieve extends BroadcastReceiver {    @Override    public void onReceive(Context context, Intent intent) {        //TODO sth.    }}

一种是有序的通过设置priority的优先级来排序 -1000~1000 利用abortBroadcast()结束传播

发送:

sendOrderedBroadcast(intent, null);

多个广播接收者之间传值：

Bundle bundle=new Bundle();        bundle.putString("a", "fdsfs");        setResultExtras(bundle);//取值getResultExtras(false).getString("a")

配置:

<receiver android:name=".MySecBroad">            <!--android:priority优先级  -->            <intent-filter android:priority="20">                <action android:name="com.mytest.action_MY_BROADCAST"/>            </intent-filter>        </receiver>

手动注册BroadCastReceiver:

MySecBroad receiver=new MySecbroad();IntentFilter filter=new IntentFilter();filter.addAction(TEST_ACTION);registerReceiver(receiver,filter);
