一、运行效果图

这里写图片描述

程序代码

MainActivity

public class MainActivity extends AppCompatActivity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);    }    public void send(View view)    {        Intent intent = new Intent();        //定义广播事件类型        intent.setAction("Intercept_Stitch");        // 发送广播        sendOrderedBroadcast(intent,null);    }}

MyReceiveOne

ublic class MyReceiverOne extends BroadcastReceiver {    public MyReceiverOne() {    }    @Override    public void onReceive(Context context, Intent intent) {        Log.i("MyBroadcaseReceiverOne","自定义广播One");    }}

MyReceiveTwo

public class MyReceiverTwo extends BroadcastReceiver {    public MyReceiverTwo() {    }    @Override    public void onReceive(Context context, Intent intent) {        Log.i("MyBroadcaseReceiverTwo","自定义广播Two");        abortBroadcast();//拦截有序广播        Log.i("MyBroadcaseReceiverTwo","有序广播Two,广播被我冻结");    }}

MyreceiveThree

public class MyReceiverThree extends BroadcastReceiver {    public MyReceiverThree() {    }    @Override    public void onReceive(Context context, Intent intent) {        Log.i("MyBroadcaseReceiverThree","自定义广播Three");    }}

AndroidMainfest

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="cn.edu.bzu.broadrecedemo3">    <application        android:allowBackup="true"        android:icon="@mipmap/ic_launcher"        android:label="@string/app_name"        android:supportsRtl="true"        android:theme="@style/AppTheme">        <activity android:name=".MainActivity">            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </activity>        <receiver            android:name=".MyReceiverOne"            android:enabled="true"            android:exported="true">            <intent-filter android:priority="1000">                <action android:name="Intercept_Stitch"/>            </intent-filter>        </receiver>        <receiver            android:name=".MyReceiverTwo"            android:enabled="true"            android:exported="true">            <intent-filter android:priority="200">                <action android:name="Intercept_Stitch"/>            </intent-filter>        </receiver>        <receiver            android:name=".MyReceiverThree"            android:enabled="true"            android:exported="true">            <intent-filter android:priority="600">                <action android:name="Intercept_Stitch"/>            </intent-filter>        </receiver>    </application></manifest>

运行结果

LogCat 广播在优先级最低的MyReceiveTwo中被终结
若优先级相同，根据注册顺序来确定接收广播的顺序
