BroadcastReceiver 使用

1. 静态注册BroadcastReceiver

MyBroadcastReceiver.java

package com.example.mybroadcastreceiver;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.util.Log;public class MyBroadcastReceiver extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent intent) {// TODO Auto-generated method stubif (intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED")) {Log.i("BroadcastReceiver", "android.provider.Telephony.SMS_RECEIVED");}}}

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.example.mybroadcastreceiver"    android:versionCode="1"    android:versionName="1.0" >    <uses-sdk        android:minSdkVersion="8"        android:targetSdkVersion="17" /><uses-permission android:name="android.permission.RECEIVE_SMS"/><uses-permission android:name="android.permission.SEND_SMS"/>    <application        android:allowBackup="true"        android:icon="@drawable/ic_launcher"        android:label="@string/app_name"        android:theme="@style/AppTheme" >        <activity            android:name="com.example.mybroadcastreceiver.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>        <receiver android:name=".MyBroadcastReceiver">            <intent-filter android:priority="1000">            <action android:name="android.provider.Telephony.SMS_RECEIVED"/>        </intent-filter>        </receiver>    </application></manifest>

2. 动态注册BroadcastReceiver

MainActivity.java

package com.example.mybroadcastreceiver;import android.app.Activity;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.content.IntentFilter;import android.os.Bundle;import android.util.Log;public class MainActivity extends Activity {IntentFilter intentFilter = new IntentFilter("android.provider.Telephony.SMS_RECEIVED");@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);}@Overrideprotected void onPause() {// TODO Auto-generated method stubsuper.onPause();unregisterReceiver(myBroadcastReceiver);}@Overrideprotected void onResume() {// TODO Auto-generated method stubsuper.onResume();registerReceiver(myBroadcastReceiver, intentFilter);}BroadcastReceiver myBroadcastReceiver = new BroadcastReceiver() {@Overridepublic void onReceive(Context context, Intent intent) {// TODO Auto-generated method stubif (intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED")) {Log.i("BroadcastReceiver", "android.provider.Telephony.SMS_RECEIVED");}}};}

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.example.mybroadcastreceiver"    android:versionCode="1"    android:versionName="1.0" >    <uses-sdk        android:minSdkVersion="8"        android:targetSdkVersion="17" /><uses-permission android:name="android.permission.RECEIVE_SMS"/><uses-permission android:name="android.permission.SEND_SMS"/>    <application        android:allowBackup="true"        android:icon="@drawable/ic_launcher"        android:label="@string/app_name"        android:theme="@style/AppTheme" >        <activity            android:name="com.example.mybroadcastreceiver.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>    </application></manifest>

3 发送广播与接收广播消息

MainActivity.java

package com.example.broadcast;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.util.Log;public class MainActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);Intent intent = new Intent("com.example.broadcast");sendBroadcast(intent);Log.i("Broadcast", "发送广播");}}

MyBroadcastReceiver.java

package com.example.broadcast;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.util.Log;public class MyBroadcastReceiver extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent intent) {// TODO Auto-generated method stubif (intent.getAction().equals("com.example.broadcast")) {Log.i("Broadcast", "接收到广播");}}}

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.example.broadcast"    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.broadcast.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>        <receiver android:name=".MyBroadcastReceiver">            <intent-filter android:priority="1000">                <action android:name="com.example.broadcast"/>            </intent-filter>        </receiver>    </application></manifest>
