跨程序之间的广播传值

第一个应用程序：Broadcast

【MainActivity.java】

package com.example.broadcast;import android.os.Bundle;import android.app.Activity;import android.content.Intent;public class MainActivity extends Activity {public final static String SEND_OK_MESSAGE = "send.ok.message";@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main); Intent intent = new Intent(SEND_OK_MESSAGE);         intent.putExtra("name", "AnJon");         sendBroadcast(intent);}}

第二个应用程序：Broadcast1

【MainActivity.java】

package com.example.broadcast1;import android.os.Bundle;import android.app.Activity;import android.content.Intent;public class MainActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);Intent i = new Intent(this, MyService.class);startService(i);}}

【MyService.java】

package com.example.broadcast1;import android.app.Service;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.content.IntentFilter;import android.os.IBinder;import android.widget.Toast;public class MyService extends Service {public final static String SEND_OK_MESSAGE = "send.ok.message";private BroadcastReceiver myBroadCast = new BroadcastReceiver() {@Overridepublic void onReceive(Context context, Intent intent) {String action = intent.getAction();if (action.equals(SEND_OK_MESSAGE)) {Toast.makeText(context,"接收到了一条广播为" + SEND_OK_MESSAGE+ intent.getStringExtra("name"),Toast.LENGTH_LONG).show();}}};@Overridepublic void onCreate() {super.onCreate();}@Overridepublic void onStart(Intent intent, int startId) {IntentFilter myFilter = new IntentFilter();myFilter.addAction(SEND_OK_MESSAGE);this.registerReceiver(myBroadCast, myFilter);super.onStart(intent, startId);}@Overridepublic IBinder onBind(Intent arg0) {return null;}}

【AndroidManifest.xml】清单文件

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.example.broadcast1"    android:versionCode="1"    android:versionName="1.0" >    <uses-sdk        android:minSdkVersion="8"        android:targetSdkVersion="17" />    <application        android:allowBackup="true"        android:icon="@drawable/ic_launcher"        android:label="@string/app_name"        android:theme="@style/AppTheme" >        <activity            android:name="com.example.broadcast1.MainActivity"            android:label="@string/app_name" >            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </activity>        <service android:name=".MyService"><intent-filter><action android:name="com.example.broadcast1.MyService"></action></intent-filter><intent-filter><action android:name="send.ok.message" /></intent-filter></service>    </application></manifest>
