Android实现发送一条有序广播

实验目标：掌握有序广播的使用*
1：设计布局文件

<?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:paddingBottom="@dimen/activity_vertical_margin"    android:background="@drawable/stitch_one"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    tools:context="com.edu.bzu.myapplication.MainActivity">    <Button        android:text="发送有序广播"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_centerHorizontal="true"        android:layout_marginTop="80dp"        android:paddingLeft="5dp"        android:onClick="send"        android:textSize="20sp"        android:background="#FBFBFF"        android:paddingRight="5dp"        android:id="@+id/button" /></RelativeLayout>

2：编写界面交互代码
点击事件处理方法：

package com.edu.bzu.myapplication;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        sendBroadcast(intent,null);    }}

3：修改权限并注册广播接受者

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.edu.bzu.myapplication">    <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=".MybroadcastReceiverOne"            android:enabled="true"            android:exported="true">            <intent-filter android:priority="100"/>        </receiver>        <receiver android:name=".MybroadcastReceiverOne">            <intent-filter android:priority="1000" >                <action android:name="Intercept_Stitch"/>              </intent-filter>        <!--<receiver android:name=".MybroadcastReceiverTwo">-->            <!--<intent-filter android:priority="200" >-->                <!--<action android:name="Intercept_Stitch"/>-->            <!--</intent-filter>-->        <!--<receiver android:name=".MybroadcastReceiverThree">-->            <!--<intent-filter android:priority="600" >-->                <!--<action android:name="Intercept_Stitch"/>-->            <!--</intent-filter>-->        <!--</receiver>-->    </application></manifest>

4：创建广播接受者MybroadcastReceiverOne

package com.edu.bzu.myapplication;import android.app.Service;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.os.IBinder;import android.util.Log;public class MybroadcastReceiverOne extends BroadcastReceiver {    public MybroadcastReceiverOne() {    }    @Override    public void onReceive(Context context, Intent intent) {        Log.i("MybroadcastReceiverOne","自定义的广播接受者One，接收到了广播事件");        abortBroadcast();//        Log.i("MybroadcastReceiverTwo","我是广播接受者Two，广播被我终结了！");    }}

5：运行结果显示：
