Android 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);
