在后台运行的Service能不能自己接收广播消息？

[xqhrs232]

SERVICE可以自己发广播消息，也可以提供接口（IBINDER机制）被ACTIVITY调用，但不知道它自己能不能接手广播消息而不要ACTIVITY的参与。

[儿大不由爷]

肯定是可以的，需要做个BroadcastReceiver

[Sodino]

可以的

我看到很多例子都是不行的啊！都是有ACTIVITY的参与。如果可以在工程的XML文件中RECIVER指定给谁？ACTIVITY吗？那不还是由ACTIVITY接收的？

完全可以，例如在播放音乐的service类MusicService中实现监听电话广播的类PhoneStatReceiver
manifest写法如下：
<receiver android:name=".MusicService$PhoneStatReceiver">
...
</receiver>

你这个是不是要求PhoneStatReceiver类为MusicService类的内部类？

是内部类，从.MusicService$PhoneStatReceiver就可以看出来。

不知道是不是因为在XML文件里面的放的分支不对还是什么其它。

android-轻松监听来电和去电
http://www.devdiv.com/article-1645-1.html

要监听android打电话和接电话，只需下面2步骤
1.第一步，写一个Receiver继承自BroadcastReceiver
public class PhoneStatReceiver extends BroadcastReceiver{
        
        private static final String TAG = "PhoneStatReceiver";
        
//        private static MyPhoneStateListener phoneListener = new MyPhoneStateListener();
        
        private static boolean incomingFlag = false;
        
        private static String incoming_number = null;

        @Override
        public void onReceive(Context context, Intent intent) {
                //如果是拨打电话
                if(intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)){                        
                        incomingFlag = false;
                        String phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);        
                        Log.i(TAG, "call OUT:"+phoneNumber);                        
                }else{                        
                        //如果是来电
                        TelephonyManager tm = 
                            (TelephonyManager)context.getSystemService(Service.TELEPHONY_SERVICE);                        
                        
                        switch (tm.getCallState()) {
                        case TelephonyManager.CALL_STATE_RINGING:
                                incomingFlag = true;//标识当前是来电
                                incoming_number = intent.getStringExtra("incoming_number");
                                Log.i(TAG, "RINGING :"+ incoming_number);
                                break;
                        case TelephonyManager.CALL_STATE_OFFHOOK:                                
                                if(incomingFlag){
                                        Log.i(TAG, "incoming ACCEPT :"+ incoming_number);
                                }
                                break;
                        
                        case TelephonyManager.CALL_STATE_IDLE:                                
                                if(incomingFlag){
                                        Log.i(TAG, "incoming IDLE");                               
                                }
                                break;
                        } 
                }
        }
}

第二步：在AndroidManifest.xml，配置写好的Receiver，并拦截相应的BroadCastAction，
另外注意加上相应的权限。
<receiver android:name=".filter.PhoneStatReceiver">  
            <intent-filter>
                 <action android:name="android.intent.action.PHONE_STATE"/>           
                 <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
            </intent-filter>
</receiver>

<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
        <uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"></uses-permission>

Android下实现程序关闭后，监听取消
http://www.cnblogs.com/tt_mc/archive/2010/03/03/1677474.html

[xqhrs232]

如下用语句注册才是可以的

package com.demo;
import android.app.Service;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.os.IBinder;
import android.telephony.gsm.SmsMessage;

public class ListenService extends Service {
public static final String SvrId = "RARNU.SERVICE.DEMO";
public static final String strACT = "android.provider.Telephony.SMS_RECEIVED";
private SMSMsgReceiver recv;
@Override
public void onStart(Intent intent, int startId) {
super.onStart(intent, startId);
}
@Override
public void onCreate() {
IntentFilter filter = new IntentFilter(strACT);
recv = new SMSMsgReceiver();
registerReceiver(recv, filter);
super.onCreate();
}
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public void onDestroy() {
unregisterReceiver(recv);
super.onDestroy();
}
public class SMSMsgReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(strACT)) {
StringBuilder sb = new StringBuilder();
Bundle bundle = intent.getExtras();
if (bundle != null) {
Object[] pdus = (Object[]) bundle.get("pdus");
SmsMessage[] msg = new SmsMessage[pdus.length];
for (int i = 0; i < pdus.length; i++) {
msg[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
}
for (SmsMessage currMsg : msg) {
sb.append("From:");
sb.append(currMsg.getDisplayOriginatingAddress());
sb.append("\nMessage:");
sb.append(currMsg.getDisplayMessageBody());
}
}
Intent i = new Intent(SvrId);
i.putExtra("PARAM", sb.toString());
sendBroadcast(i);
}
}
}
}
