发送有序广播

1.首先创建布局文件：

<?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:background="@drawable/stitch_one"

    tools:context=".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.添加广播接收者：

 package com.example.bz0209.receiver;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

import android.util.Log;

 public class MyReceiverthree extends BroadcastReceiver {

    public MyReceiverthree() {

    }

    @Override

    public void onReceive(Context context, Intent intent) {

        // TODO: This method is called when the BroadcastReceiver is receiving

        // an Intent broadcast.

        Log.i("MyReceiverthree","自定义的广播接收者three,接受到了广播事件");

        Log.i("MyReceiverthree",intent.getAction());

    }

}

package com.example.bz0209.receiver;

import android.content.Intent;

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.util.Log;

import android.view.View;

import android.widget.Toast;

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();

        intent.setAction("Intercept_Stitch");

        sendOrderedBroadcast(intent,null);

    }

}

package com.example.bz0209.receiver;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

import android.util.Log;

public class MyReceiverone extends BroadcastReceiver {

    public MyReceiverone() {

    }

    @Override

    public void onReceive(Context context, Intent intent) {

        // TODO: This method is called when the BroadcastReceiver is receiving

        // an Intent broadcast.

        Log.i("MyReceiverone","自定义的广播接收者one，接受到了广播事件");

        Log.i("MyReceiverone",intent.getAction());

    }

}

3.编写MainActivity代码：

import android.content.Intent;

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.util.Log;

import android.view.View;

import android.widget.Toast;

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();

        intent.setAction("Intercept_Stitch");

        sendOrderedBroadcast(intent,null);

    }

}

4.编写清单文件代码：

?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    package="com.example.bz0209.receiver">

    <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=".MyReceivertwo"

            android:enabled="true"

            android:exported="true" >

            <intent-filter android:priority="1000">

                <action android:name="Intercept_Stitch"/>

            </intent-filter>

            </receiver>

        <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=".MyReceiverthree"

            android:enabled="true"

            android:exported="true">

            <intent-filter android:priority="600">

                <action android:name="Intercept_Stitch"/>

            </intent-filter>

        </receiver>

    </application>

</manifest>
