1.编写用户交互界面:

<?xml version="1.0"
encoding="utf-8"
?><RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"
   android:id="@+id/activity_main"    android:layout_width="match_parent"
   android:layout_height="match_parent"   android:background="@drawable/stitch_one"
   tools:context="bzu.edu.cn.guangbo.MainActivity"
>

 

    <Button        android:layout_width="wrap_content"
       android:layout_height="wrap_content"        android:layout_centerHorizontal="true"
       android:layout_marginTop="80dp"        android:onClick="send"
       android:text="发送有序广播"        android:paddingLeft="5dp"
       android:paddingRight="5dp"        android:background="#FBFBFF"
       android:textSize="20sp"
/>

</RelativeLayout>

2点击发送有序广播按钮时事件处理

package bzu.edu.cn.guangbo;

import android.content.Intent;import
android.support.v7.app.AppCompatActivity;import
android.os.Bundle;import
android.view.View;

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();

        //定义广播的事件类型        intent.setAction("Intercept_Stitch");

        //发送广播        sendOrderedBroadcast(intent,null);

 

    }

}

3.创建广播接收者

package bzu.edu.cn.guangbo;

import android.content.BroadcastReceiver;import
android.content.Context;import
android.content.Intent;import
android.util.Log;

public class MyBroadcastReceiverOne
extends BroadcastReceiver {

    public
MyBroadcastReceiverOne() {

    }

 

    @Override    public void
onReceive(Context context, Intent intent) {

        //
TODO: This method is called when the BroadcastReceiver is receiving        // an Intent broadcast.        //throw new UnsupportedOperationException("Not yet implemented");
       Log.i("MyBroadcastReceiverOne","自定义的广播者one,接收到了广播事件");

 

 

    }

 

}

package bzu.edu.cn.guangbo;

import android.content.BroadcastReceiver;import
android.content.Context;import
android.content.Intent;import
android.util.Log;

public class MyBroadcastReceiverTwo
extends BroadcastReceiver {

    public
MyBroadcastReceiverTwo() {

    }

 

    @Override    public void
onReceive(Context context, Intent intent) {

        //
TODO: This method is called when the BroadcastReceiver is receiving        // an Intent broadcast.        //throw new UnsupportedOperationException("Not yet implemented");
       Log.i("MyBroadcastReceiverTwo","自定义的广播者two,接收到了广播事件");

               

    }

}

 

 

 

package bzu.edu.cn.guangbo;

import android.content.BroadcastReceiver;import
android.content.Context;import
android.content.Intent;import
android.util.Log;

public class MyBroadcastReceiverThree
extends BroadcastReceiver {

    public
MyBroadcastReceiverThree() {

    }

 

    @Override    public void
onReceive(Context context, Intent intent) {

        //
TODO: This method is called when the BroadcastReceiver is receiving        // an Intent broadcast.        //throw new UnsupportedOperationException("Not yet implemented");
       Log.i("MyBroadcastReceiverThree","自定义的广播者three,接收到了广播事件");

    }

}
