編輯:關於Android編程
我們在使用Android手機打電話時,有時可能會需要對來去電通話自動錄音,本文就詳細講解實現Android來去電通話自動錄音的方法,大家按照文中的方法編寫程序就可以完成此功能。
來去電自動錄音的關鍵在於如何監聽手機電話狀態的轉變:
1)來電的狀態的轉換如下(紅色標記是我們要用到的狀態)
空閒(IDEL)——> 響鈴(RINGING)——> 接聽(ACTIVE)——> 掛斷(經歷DISCONNECTING——DISCONNECTED)——> 空閒(IDEL)
或者 空閒(IDEL)——> 響鈴(RINGING)——> 拒接 ——> 空閒(IDEL)
2)去電狀態的轉換如下
空閒(IDEL)——> 撥號 (DIALING)——> (對方)響鈴(ALERTING) ——> 建立連接(ACTIVE)—— 掛斷(經歷DISCONNECTING——DISCONNECTED)——> 空閒(IDEL)
或者 空閒(IDEL)——> 撥號 (DIALING)——> (對方)響鈴(ALERTING)——> 掛斷/對方拒接 ——> 空閒(IDEL)
下面就分別就來電和去電這兩種狀態分析並實現。
1、先進行來電的分析和實現。
相對去電來說,來電狀態的轉換檢測要簡單些。android api 中的PhoneStateListener 類提供了相應的方法,但我們需要覆蓋其中的 onCallStateChanged(int state, String incomingNumber) 方法即可實現來電狀態的檢測,並在此基礎上添加錄音功能即可。其中 state 參數就是各種電話狀態,到時我們將它跟下面我們要用到的狀態進行比較,若是電話處在我們想要的狀態上,則進行一系列操作,否則就不管他。想要獲取這些狀態,還需要另一個電話相關類,那就是 TelephonyManager, 該類 提供了一些電話狀態,其中我們要用到的是:TelephonyManager.CALL_STATE_IDLE(空閒)、TelephonyManager.CALL_STATE_OFFHOOK(摘機)和 TelephonyManager.CALL_STATE_RINGING(來電響鈴)這三個狀態。判別這三種狀態,可以繼承 android.telephony.PhoneStateListener 類,實現上面提到的 onCallStateChanged(int state, String incomingNumber) 方法,請看如下代碼:
public class TelListener extends PhoneStateListener { @Override public void onCallStateChanged(int state, String incomingNumber) { super.onCallStateChanged(state, incomingNumber); switch (state) { case TelephonyManager.CALL_STATE_IDLE: // 空閒狀態,即無來電也無去電 Log.i("TelephoneState", "IDLE"); //此處添加一系列功能代碼 break; case TelephonyManager.CALL_STATE_RINGING: // 來電響鈴 Log.i("TelephoneState", "RINGING"); //此處添加一系列功能代碼 break; case TelephonyManager.CALL_STATE_OFFHOOK: // 摘機,即接通 Log.i("TelephoneState", "OFFHOOK"); //此處添加一系列功能代碼 break; } Log.i("TelephoneState", String.valueOf(incomingNumber)); } }
有了以上來電狀態監聽代碼還不足以實現監聽功能,還需要在我們的一個Activity或者Service中實現監聽,方法很簡單,代碼如下:
/** * 在activity 或者 service中加入如下代碼,以實現來電狀態監聽 */ TelephonyManager telMgr = (TelephonyManager)context.getSystemService( Context.TELEPHONY_SERVICE); telMgr.listen(new TelListener(), PhoneStateListener.LISTEN_CALL_STATE);
這樣就實現了來電狀態監聽功能,但要能夠在設備中跑起來,這還不夠,它還需要兩個獲取手機電話狀態的權限:
<uses-permission android:name="android.permission.READ_PHONE_STATE" /> <uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
這樣的話就可以跑起來了。
說到這,我想如果你可以實現錄音功能的話,在此基礎上實現來電自動錄音就應該沒什麼問題了,不過請容我簡單羅嗦幾句。既然是來電,那麼要想錄音的話,那麼應該就是在監聽到 TelephonyManager.CALL_STATE_OFFHOOK 的狀態時開啟錄音機開始錄音, 在監聽到TelephonyManager.CALL_STATE_IDLE 的狀態時關閉錄音機停止錄音。這樣,來電錄音功能就完成了,不要忘記錄音功能同樣需要權限:
<uses-permission android:name="android.permission.RECORD_AUDIO"/> <!-- 要存儲文件或者創建文件夾的話還需要以下兩個權限 --> <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"/> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
2、介紹完了來電自動錄音,下面就來介紹去電自動錄音的實現方法。
上面說過,相比來電狀態的監聽,去電的要麻煩些,甚至這種方法不是通用的,這個主要是因為android api 中沒有提供去電狀態監聽的相應類和方法(也許我剛接觸,沒有找到)。剛開始網上搜索了一通也沒有找到對應的解決方法,大多是 來電監聽的,也就是上面的方法。不過中途發現一篇博文(後來就搜不到了),記得是查詢系統日志的方式,從中找到去電過程中的各個狀態的關鍵詞。無奈之中,最終妥協了此方法。
我的(聯想A65上的)去電日志內容如下:
過濾關鍵詞為 mforeground
01-06 16:29:54.225: D/InCallScreen(251): onPhoneStateChanged: mForegroundCall.getState() : DIALING 01-06 16:29:54.245: V/LogInfo OutGoing Call(2492): D/InCallScreen( 251): onPhoneStateChanged: mForegroundCall.getState() : DIALING 01-06 16:29:54.631: D/InCallScreen(251): onPhoneStateChanged: mForegroundCall.getState() : DIALING 01-06 16:29:54.645: V/LogInfo OutGoing Call(2492): D/InCallScreen( 251): onPhoneStateChanged: mForegroundCall.getState() : DIALING 01-06 16:29:54.742: D/InCallScreen(251): onPhoneStateChanged: mForegroundCall.getState() : DIALING 01-06 16:29:54.766: V/LogInfo OutGoing Call(2492): D/InCallScreen( 251): onPhoneStateChanged: mForegroundCall.getState() : DIALING 01-06 16:29:54.873: D/InCallScreen(251): onPhoneStateChanged: mForegroundCall.getState() : DIALING 01-06 16:29:54.877: V/LogInfo OutGoing Call(2492): D/InCallScreen( 251): onPhoneStateChanged: mForegroundCall.getState() : DIALING 01-06 16:29:55.108: D/InCallScreen(251): onPhoneStateChanged: mForegroundCall.getState() : DIALING 01-06 16:29:55.125: V/LogInfo OutGoing Call(2492): D/InCallScreen( 251): onPhoneStateChanged: mForegroundCall.getState() : DIALING 01-06 16:29:57.030: D/InCallScreen(251): onPhoneStateChanged: mForegroundCall.getState() : ACTIVE 01-06 16:29:57.155: V/LogInfo OutGoing Call(2492): D/InCallScreen( 251): onPhoneStateChanged: mForegroundCall.getState() : ACTIVE 01-06 16:29:57.480: D/InCallScreen(251): onPhoneStateChanged: mForegroundCall.getState() : ACTIVE 01-06 16:29:57.598: V/LogInfo OutGoing Call(2492): D/InCallScreen( 251): onPhoneStateChanged: mForegroundCall.getState() : ACTIVE 01-06 16:29:59.319: D/InCallScreen(251): onPhoneStateChanged: mForegroundCall.getState() : DISCONNECTING 01-06 16:29:59.373: V/LogInfo OutGoing Call(2492): D/InCallScreen( 251): onPhoneStateChanged: mForegroundCall.getState() : DISCONNECTING 01-06 16:30:00.392: D/InCallScreen(251): - onDisconnect: currentlyIdle:true ; mForegroundCall.getState():DISCONNECTED 01-06 16:30:00.399: V/LogInfo OutGoing Call(2492): D/InCallScreen( 251): - onDisconnect: currentlyIdle:true ; mForegroundCall.getState():DISCONNECTED 01-06 16:30:01.042: D/InCallScreen(251): onPhoneStateChanged: mForegroundCall.getState() : IDLE 01-06 16:30:01.070: V/LogInfo OutGoing Call(2492): D/InCallScreen( 251): onPhoneStateChanged: mForegroundCall.getState() : IDLE 01-06 16:30:01.558: D/InCallScreen(251): onPhoneStateChanged: mForegroundCall.getState() : IDLE 01-06 16:30:01.572: V/LogInfo OutGoing Call(2492): D/InCallScreen( 251): onPhoneStateChanged: mForegroundCall.getState() : IDLE
過濾關鍵詞 mbackground
01-06 16:29:54.226: D/InCallScreen(251): onPhoneStateChanged: mBackgroundCall.getState() : IDLE 01-06 16:29:54.256: V/LogInfo OutGoing Call(2492): D/InCallScreen( 251): onPhoneStateChanged: mBackgroundCall.getState() : IDLE 01-06 16:29:54.638: D/InCallScreen(251): onPhoneStateChanged: mBackgroundCall.getState() : IDLE 01-06 16:29:54.652: V/LogInfo OutGoing Call(2492): D/InCallScreen( 251): onPhoneStateChanged: mBackgroundCall.getState() : IDLE 01-06 16:29:54.743: D/InCallScreen(251): onPhoneStateChanged: mBackgroundCall.getState() : IDLE 01-06 16:29:54.770: V/LogInfo OutGoing Call(2492): D/InCallScreen( 251): onPhoneStateChanged: mBackgroundCall.getState() : IDLE 01-06 16:29:54.875: D/InCallScreen(251): onPhoneStateChanged: mBackgroundCall.getState() : IDLE 01-06 16:29:54.882: V/LogInfo OutGoing Call(2492): D/InCallScreen( 251): onPhoneStateChanged: mBackgroundCall.getState() : IDLE 01-06 16:29:55.109: D/InCallScreen(251): onPhoneStateChanged: mBackgroundCall.getState() : IDLE 01-06 16:29:55.142: V/LogInfo OutGoing Call(2492): D/InCallScreen( 251): onPhoneStateChanged: mBackgroundCall.getState() : IDLE 01-06 16:29:57.031: D/InCallScreen(251): onPhoneStateChanged: mBackgroundCall.getState() : IDLE 01-06 16:29:57.160: V/LogInfo OutGoing Call(2492): D/InCallScreen( 251): onPhoneStateChanged: mBackgroundCall.getState() : IDLE 01-06 16:29:57.481: D/InCallScreen(251): onPhoneStateChanged: mBackgroundCall.getState() : IDLE 01-06 16:29:57.622: V/LogInfo OutGoing Call(2492): D/InCallScreen( 251): onPhoneStateChanged: mBackgroundCall.getState() : IDLE 01-06 16:29:59.319: D/InCallScreen(251): onPhoneStateChanged: mBackgroundCall.getState() : IDLE 01-06 16:29:59.373: V/LogInfo OutGoing Call(2492): D/InCallScreen( 251): onPhoneStateChanged: mBackgroundCall.getState() : IDLE 01-06 16:30:01.042: D/InCallScreen(251): onPhoneStateChanged: mBackgroundCall.getState() : IDLE 01-06 16:30:01.070: V/LogInfo OutGoing Call(2492): D/InCallScreen( 251): onPhoneStateChanged: mBackgroundCall.getState() : IDLE 01-06 16:30:01.559: D/InCallScreen(251): onPhoneStateChanged: mBackgroundCall.getState() : IDLE 01-06 16:30:01.573: V/LogInfo OutGoing Call(2492): D/InCallScreen( 251): onPhoneStateChanged: mBackgroundCall.getState() : IDLE
從上面的日志可以看到,每一行的末尾的大寫英文詞就是去電的狀態,狀態說明如下:
由於我撥打的是10010,沒有響鈴過程(電腦自動接通的夠快),還少了一個狀態,狀態是ALERTING ,這個就是對方正在響鈴的狀態。
有了這幾個去電狀態就好辦了,現在我們要做的就是讀取系統日志,然後找到這些狀態,提取的關鍵詞就是上面提到的 mforeground(前台通話狀態) 和 mbackground (後台通話狀態)(可能不一樣的設備生成的不一樣,根據自己具體設備設置,這裡只提取前台的),如果讀取的這一行日志中 包含 mforground ,再看看是否包含上面的狀態的單詞。既然說的如此,那麼看看讀取系統日志的代碼吧。
package com.sdvdxl.phonerecorder; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; import com.sdvdxl.outgoingcall.OutgoingCallState; import android.content.Context; import android.content.Intent; import android.util.Log; /** * * @author sdvdxl * 找到 日志中的 * onPhoneStateChanged: mForegroundCall.getState() 這個是前台呼叫狀態 * mBackgroundCall.getState() 後台電話 * 若 是 DIALING 則是正在撥號,等待建立連接,但對方還沒有響鈴, * ALERTING 呼叫成功,即對方正在響鈴, * 若是 ACTIVE 則已經接通 * 若是 DISCONNECTED 則本號碼呼叫已經掛斷 * 若是 IDLE 則是處於 空閒狀態 * */ public class ReadLog extends Thread { private Context ctx; private int logCount; private static final String TAG = "LogInfo OutGoing Call"; /** * 前後台電話 * @author sdvdxl * */ private static class CallViewState { public static final String FORE_GROUND_CALL_STATE = "mForeground"; } /** * 呼叫狀態 * @author sdvdxl * */ private static class CallState { public static final String DIALING = "DIALING"; public static final String ALERTING = "ALERTING"; public static final String ACTIVE = "ACTIVE"; public static final String IDLE = "IDLE"; public static final String DISCONNECTED = "DISCONNECTED"; } public ReadLog(Context ctx) { this.ctx = ctx; } /** * 讀取Log流 * 取得呼出狀態的log * 從而得到轉換狀態 */ @Override public void run() { Log.d(TAG, "開始讀取日志記錄"); String[] catchParams = {"logcat", "InCallScreen *:s"}; String[] clearParams = {"logcat", "-c"}; try { Process process=Runtime.getRuntime().exec(catchParams); InputStream is = process.getInputStream(); BufferedReader reader = new BufferedReader(new InputStreamReader(is)); String line = null; while ((line=reader.readLine())!=null) { logCount++; //輸出所有 Log.v(TAG, line); //日志超過512條就清理 if (logCount>512) { //清理日志 Runtime.getRuntime().exec(clearParams) .destroy();//銷毀進程,釋放資源 logCount = 0; Log.v(TAG, "-----------清理日志---------------"); } /*---------------------------------前台呼叫-----------------------*/ //空閒 if (line.contains(ReadLog.CallViewState.FORE_GROUND_CALL_STATE) && line.contains(ReadLog.CallState.IDLE)) { Log.d(TAG, ReadLog.CallState.IDLE); } //正在撥號,等待建立連接,即已撥號,但對方還沒有響鈴, if (line.contains(ReadLog.CallViewState.FORE_GROUND_CALL_STATE) && line.contains(ReadLog.CallState.DIALING)) { Log.d(TAG, ReadLog.CallState.DIALING); } //呼叫對方 正在響鈴 if (line.contains(ReadLog.CallViewState.FORE_GROUND_CALL_STATE) && line.contains(ReadLog.CallState.ALERTING)) { Log.d(TAG, ReadLog.CallState.ALERTING); } //已接通,通話建立 if (line.contains(ReadLog.CallViewState.FORE_GROUND_CALL_STATE) && line.contains(ReadLog.CallState.ACTIVE)) { Log.d(TAG, ReadLog.CallState.ACTIVE); } //斷開連接,即掛機 if (line.contains(ReadLog.CallViewState.FORE_GROUND_CALL_STATE) && line.contains(ReadLog.CallState.DISCONNECTED)) { Log.d(TAG, ReadLog.CallState.DISCONNECTED); } } //END while } catch (IOException e) { e.printStackTrace(); } //END try-catch } //END run } //END class ReadLog
以上代碼中,之所以用線程,是為了防止讀取日志過程中阻滯主方法的其他方法的執行,影響到程序捕捉對應的電話狀態。
好了,捕捉到了去電過程中各個狀態的轉變,那麼,如何通知給程序呢,我采用的方法是捕獲後立馬給系統發送廣播,然後程序進行廣播接收,接收後再處理錄音事件。要發送廣播,就要發送一個唯一的廣播,為此,建立如下類:
package com.sdvdxl.outgoingcall; import com.sdvdxl.phonerecorder.ReadLog; import android.content.Context; import android.util.Log; public class OutgoingCallState { Context ctx; public OutgoingCallState(Context ctx) { this.ctx = ctx; } /** * 前台呼叫狀態 * @author sdvdxl * */ public static final class ForeGroundCallState { public static final String DIALING = "com.sdvdxl.phonerecorder.FORE_GROUND_DIALING"; public static final String ALERTING = "com.sdvdxl.phonerecorder.FORE_GROUND_ALERTING"; public static final String ACTIVE = "com.sdvdxl.phonerecorder.FORE_GROUND_ACTIVE"; public static final String IDLE = "com.sdvdxl.phonerecorder.FORE_GROUND_IDLE"; public static final String DISCONNECTED = "com.sdvdxl.phonerecorder.FORE_GROUND_DISCONNECTED"; } /** * 開始監聽呼出狀態的轉變, * 並在對應狀態發送廣播 */ public void startListen() { new ReadLog(ctx).start(); Log.d("Recorder", "開始監聽呼出狀態的轉變,並在對應狀態發送廣播"); } }
程序需要讀取系統日志權限:
XML/HTML代碼
<uses-permission android:name="android.permission.READ_LOGS"/>
然後,在讀取日志的類中檢測到去電各個狀態的地方發送一個廣播,那麼,讀取日志的完整代碼如下:
package com.sdvdxl.phonerecorder; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; import com.sdvdxl.outgoingcall.OutgoingCallState; import android.content.Context; import android.content.Intent; import android.util.Log; /** * * @author mrloong * 找到 日志中的 * onPhoneStateChanged: mForegroundCall.getState() 這個是前台呼叫狀態 * mBackgroundCall.getState() 後台電話 * 若 是 DIALING 則是正在撥號,等待建立連接,但對方還沒有響鈴, * ALERTING 呼叫成功,即對方正在響鈴, * 若是 ACTIVE 則已經接通 * 若是 DISCONNECTED 則本號碼呼叫已經掛斷 * 若是 IDLE 則是處於 空閒狀態 * */ public class ReadLog extends Thread { private Context ctx; private int logCount; private static final String TAG = "LogInfo OutGoing Call"; /** * 前後台電話 * @author sdvdxl * */ private static class CallViewState { public static final String FORE_GROUND_CALL_STATE = "mForeground"; } /** * 呼叫狀態 * @author sdvdxl * */ private static class CallState { public static final String DIALING = "DIALING"; public static final String ALERTING = "ALERTING"; public static final String ACTIVE = "ACTIVE"; public static final String IDLE = "IDLE"; public static final String DISCONNECTED = "DISCONNECTED"; } public ReadLog(Context ctx) { this.ctx = ctx; } /** * 讀取Log流 * 取得呼出狀態的log * 從而得到轉換狀態 */ @Override public void run() { Log.d(TAG, "開始讀取日志記錄"); String[] catchParams = {"logcat", "InCallScreen *:s"}; String[] clearParams = {"logcat", "-c"}; try { Process process=Runtime.getRuntime().exec(catchParams); InputStream is = process.getInputStream(); BufferedReader reader = new BufferedReader(new InputStreamReader(is)); String line = null; while ((line=reader.readLine())!=null) { logCount++; //輸出所有 Log.v(TAG, line); //日志超過512條就清理 if (logCount>512) { //清理日志 Runtime.getRuntime().exec(clearParams) .destroy();//銷毀進程,釋放資源 logCount = 0; Log.v(TAG, "-----------清理日志---------------"); } /*---------------------------------前台呼叫-----------------------*/ //空閒 if (line.contains(ReadLog.CallViewState.FORE_GROUND_CALL_STATE) && line.contains(ReadLog.CallState.IDLE)) { Log.d(TAG, ReadLog.CallState.IDLE); } //正在撥號,等待建立連接,即已撥號,但對方還沒有響鈴, if (line.contains(ReadLog.CallViewState.FORE_GROUND_CALL_STATE) && line.contains(ReadLog.CallState.DIALING)) { //發送廣播 Intent dialingIntent = new Intent(); dialingIntent.setAction(OutgoingCallState.ForeGroundCallState.DIALING); ctx.sendBroadcast(dialingIntent); Log.d(TAG, ReadLog.CallState.DIALING); } //呼叫對方 正在響鈴 if (line.contains(ReadLog.CallViewState.FORE_GROUND_CALL_STATE) && line.contains(ReadLog.CallState.ALERTING)) { //發送廣播 Intent dialingIntent = new Intent(); dialingIntent.setAction(OutgoingCallState.ForeGroundCallState.ALERTING); ctx.sendBroadcast(dialingIntent); Log.d(TAG, ReadLog.CallState.ALERTING); } //已接通,通話建立 if (line.contains(ReadLog.CallViewState.FORE_GROUND_CALL_STATE) && line.contains(ReadLog.CallState.ACTIVE)) { //發送廣播 Intent dialingIntent = new Intent(); dialingIntent.setAction(OutgoingCallState.ForeGroundCallState.ACTIVE); ctx.sendBroadcast(dialingIntent); Log.d(TAG, ReadLog.CallState.ACTIVE); } //斷開連接,即掛機 if (line.contains(ReadLog.CallViewState.FORE_GROUND_CALL_STATE) && line.contains(ReadLog.CallState.DISCONNECTED)) { //發送廣播 Intent dialingIntent = new Intent(); dialingIntent.setAction(OutgoingCallState.ForeGroundCallState.DISCONNECTED); ctx.sendBroadcast(dialingIntent); Log.d(TAG, ReadLog.CallState.DISCONNECTED); } } //END while } catch (IOException e) { e.printStackTrace(); } //END try-catch } //END run } //END class ReadLog
發送了廣播,那麼就要有接收者,定義接收者如下(關於錄音機的代碼可以先忽略):
package com.sdvdxl.phonerecorder; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.util.Log; import com.sdvdxl.outgoingcall.OutgoingCallState; public class OutgoingCallReciver extends BroadcastReceiver { static final String TAG = "Recorder"; private MyRecorder recorder; public OutgoingCallReciver() { recorder = new MyRecorder(); } public OutgoingCallReciver (MyRecorder recorder) { this.recorder = recorder; } @Override public void onReceive(Context ctx, Intent intent) { String phoneState = intent.getAction(); if (phoneState.equals(Intent.ACTION_NEW_OUTGOING_CALL)) { String phoneNum = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);//撥出號碼 recorder.setPhoneNumber(phoneNum); recorder.setIsCommingNumber(false); Log.d(TAG, "設置為去電狀態"); Log.d(TAG, "去電狀態 呼叫:" + phoneNum); } if (phoneState.equals(OutgoingCallState.ForeGroundCallState.DIALING)) { Log.d(TAG, "正在撥號..."); } if (phoneState.equals(OutgoingCallState.ForeGroundCallState.ALERTING)) { Log.d(TAG, "正在呼叫..."); } if (phoneState.equals(OutgoingCallState.ForeGroundCallState.ACTIVE)) { if (!recorder.isCommingNumber() && !recorder.isStarted()) { Log.d(TAG, "去電已接通 啟動錄音機"); recorder.start(); } } if (phoneState.equals(OutgoingCallState.ForeGroundCallState.DISCONNECTED)) { if (!recorder.isCommingNumber() && recorder.isStarted()) { Log.d(TAG, "已掛斷 關閉錄音機"); recorder.stop(); } } } }
其中有這麼一段代碼:
String phoneState = intent.getAction(); if (phoneState.equals(Intent.ACTION_NEW_OUTGOING_CALL)) { String phoneNum = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);//撥出號碼 recorder.setPhoneNumber(phoneNum); recorder.setIsCommingNumber(false); Log.d(TAG, "設置為去電狀態"); Log.d(TAG, "去電狀態 呼叫:" + phoneNum); }
這裡是接收系統發出的廣播,用於接收去電廣播。這樣,就獲得了去電狀態。
3、有了以上主要代碼,可以說,來去電監聽功能算是完成了,下面創建一個service來運行監聽:
package com.sdvdxl.service; import android.app.Service; import android.content.Context; import android.content.Intent; import android.content.IntentFilter; import android.os.IBinder; import android.telephony.PhoneStateListener; import android.telephony.TelephonyManager; import android.util.Log; import android.widget.Toast; import com.sdvdxl.outgoingcall.OutgoingCallState; import com.sdvdxl.phonerecorder.MyRecorder; import com.sdvdxl.phonerecorder.OutgoingCallReciver; import com.sdvdxl.phonerecorder.TelListener; public class PhoneCallStateService extends Service { private OutgoingCallState outgoingCallState; private OutgoingCallReciver outgoingCallReciver; private MyRecorder recorder; @Override public void onCreate() { super.onCreate(); //------以下應放在onStartCommand中,但2.3.5以下版本不會因service重新啟動而重新調用-------- //監聽電話狀態,如果是打入且接聽 或者 打出 則開始自動錄音 //通話結束,保存文件到外部存儲器上 Log.d("Recorder", "正在監聽中..."); recorder = new MyRecorder(); outgoingCallState = new OutgoingCallState(this); outgoingCallReciver = new OutgoingCallReciver(recorder); outgoingCallState.startListen(); Toast.makeText(this, "服務已啟動", Toast.LENGTH_LONG).show(); //去電 IntentFilter outgoingCallFilter = new IntentFilter(); outgoingCallFilter.addAction(OutgoingCallState.ForeGroundCallState.IDLE); outgoingCallFilter.addAction(OutgoingCallState.ForeGroundCallState.DIALING); outgoingCallFilter.addAction(OutgoingCallState.ForeGroundCallState.ALERTING); outgoingCallFilter.addAction(OutgoingCallState.ForeGroundCallState.ACTIVE); outgoingCallFilter.addAction(OutgoingCallState.ForeGroundCallState.DISCONNECTED); outgoingCallFilter.addAction("android.intent.action.PHONE_STATE"); outgoingCallFilter.addAction("android.intent.action.NEW_OUTGOING_CALL"); //注冊接收者 registerReceiver(outgoingCallReciver, outgoingCallFilter); //來電 TelephonyManager telmgr = (TelephonyManager)getSystemService( Context.TELEPHONY_SERVICE); telmgr.listen(new TelListener(recorder), PhoneStateListener.LISTEN_CALL_STATE); } @Override public IBinder onBind(Intent intent) { // TODO Auto-generated method stub return null; } @Override public void onDestroy() { super.onDestroy(); unregisterReceiver(outgoingCallReciver); Toast.makeText( this, "已關閉電話監聽服務", Toast.LENGTH_LONG) .show(); Log.d("Recorder", "已關閉電話監聽服務"); } @Override public int onStartCommand(Intent intent, int flags, int startId) { return START_STICKY; } }
注冊以下service:
XML/HTML代碼
<service android:name="com.sdvdxl.service.PhoneCallStateService" />
到此為止,來去電狀態的監聽功能算是完成了,剩下一個錄音機,附上錄音機代碼如下:
package com.sdvdxl.phonerecorder; import java.io.File; import java.io.IOException; import java.text.SimpleDateFormat; import java.util.Date; import android.media.MediaRecorder; import android.os.Environment; import android.util.Log; public class MyRecorder { private String phoneNumber; private MediaRecorder mrecorder; private boolean started = false; //錄音機是否已經啟動 private boolean isCommingNumber = false;//是否是來電 private String TAG = "Recorder"; public MyRecorder(String phoneNumber) { this.setPhoneNumber(phoneNumber); } public MyRecorder() { } public void start() { started = true; mrecorder = new MediaRecorder(); File recordPath = new File( Environment.getExternalStorageDirectory() , "/My record"); if (!recordPath.exists()) { recordPath.mkdirs(); Log.d("recorder", "創建目錄"); } String callDir = "呼出"; if (isCommingNumber) { callDir = "呼入"; } String fileName = callDir + "-" + phoneNumber + "-" + new SimpleDateFormat("yy-MM-dd_HH-mm-ss") .format(new Date(System.currentTimeMillis())) + ".mp3";//實際是3gp File recordName = new File(recordPath, fileName); try { recordName.createNewFile(); Log.d("recorder", "創建文件" + recordName.getName()); } catch (IOException e) { e.printStackTrace(); } mrecorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT); mrecorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT); mrecorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT); mrecorder.setOutputFile(recordName.getAbsolutePath()); try { mrecorder.prepare(); } catch (IllegalStateException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } mrecorder.start(); started = true; Log.d(TAG , "錄音開始"); } public void stop() { try { if (mrecorder!=null) { mrecorder.stop(); mrecorder.release(); mrecorder = null; } started = false; } catch (IllegalStateException e) { e.printStackTrace(); } Log.d(TAG , "錄音結束"); } public void pause() { } public String getPhoneNumber() { return phoneNumber; } public void setPhoneNumber(String phoneNumber) { this.phoneNumber = phoneNumber; } public boolean isStarted() { return started; } public void setStarted(boolean hasStarted) { this.started = hasStarted; } public boolean isCommingNumber() { return isCommingNumber; } public void setIsCommingNumber(boolean isCommingNumber) { this.isCommingNumber = isCommingNumber; } }
到此,來去電通話自動錄音的所有功能就完成了,大家可以自己試著編寫並實現。
以上就是對Android 電話錄音的開發,希望能幫助有需要的朋友,謝謝大家對本站的支持!
