通过sendOrderedBroadcast()方法发送一条有序广播

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");

    }

}
