Android 发送有序广播

一、运行效果图

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");
}
}

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
