android 电话监听和拦截 _Android

于今腐草无萤火，终古垂杨有暮鸦。这篇文章主要讲述android 电话监听和拦截相关的知识，希望能为你提供帮助。

一、首先在manifest.xml文件中获取监听电话权限，注册监听电话的Activity

< receiver android:name=".PhoneReceiver"> < intent-filter android:priority="1000"> < action android:name="android.intent.action.PHONE_STATE"/> < action android:name="android.intent.action.NEW_OUTGOING_CALL" /> < /intent-filter> < /receiver>

1< !-- 添加访问手机电话状态的权限 --> 2< uses-permission android:name="android.permission.READ_PHONE_STATE" />

二、实现过程中主要问题为接口ITelephony，是Android系统Phone类中TelephonyManager提供给上层应用程序用户与telephony进行操作交互的接口。，必须通过AIDL（Android Interface Definition Language,即Android接口定义语言）。
具体操作就是在src文件在新建一个包，包名为：com.android.internal.telephony，在这个包里面新建一个名为ITelephony.aidl ，本文主要通过接口获得endCall()函数来拦截电话。最后rebuild project一下，在android studio 本工程的packets同目录下自动生成ITelephony.java文件

This doesn‘t place the call. It displays * the Dialer screen. * @param number the number to be dialed. If null, this * would display the Dialer screen with no number pre-filled. */ void dial(String number); /** * Place a call to the specified number. * @param number the number to be called. */ void call(String number); /** * If there is currently a call in progress, show the call screen. * The DTMF dialpad may or may not be visible initially, depending on * whether it was up when the user last exited the InCallScreen. * * @return true if the call screen was shown. */ boolean showCallScreen(); /** * Variation of showCallScreen() that also specifies whether the * DTMF dialpad should be initially visible when the InCallScreen * comes up. * * @param showDialpad if true, make the dialpad visible initially, *otherwise hide the dialpad initially. * @return true if the call screen was shown. * * @see showCallScreen */ boolean showCallScreenWithDialpad(boolean showDialpad); /** * End call or go to the Home screen * * @return whether it hung up */ boolean endCall(); /** * Answer the currently-ringing call. * * If there‘s already a current active call, that call will be * automatically put on hold.If both lines are currently in use, the * current active call will be ended. * * TODO: provide a flag to let the caller specify what policy to use * if both lines are in use.(The current behavior is hardwired to * "answer incoming, end ongoing", which is how the CALL button * is specced to behave.) * * TODO: this should be a oneway call (especially since it‘s called * directly from the key queue thread). */ void answerRingingCall(); /** * Silence the ringer if an incoming call is currently ringing. * (If vibrating, stop the vibrator also.) * * It‘s safe to call this if the ringer has already been silenced, or * even if there‘s no incoming call.(If so, this method will do nothing.) * * TODO: this should be a oneway call too (see above). *(Actually *all* the methods here that return void can *probably be oneway.) */ void silenceRinger(); /** * Check if we are in either an active or holding call * @return true if the phone state is OFFHOOK. */ boolean isOffhook(); /** * Check if an incoming phone call is ringing or call waiting. * @return true if the phone state is RINGING. */ boolean isRinging(); /** * Check if the phone is idle. * @return true if the phone state is IDLE. */ boolean isIdle(); /** * Check to see if the radio is on or not. * @return returns true if the radio is on. */ boolean isRadioOn(); /** * Check if the SIM pin lock is enabled. * @return true if the SIM pin lock is enabled. */ boolean isSimPinEnabled(); /** * Cancels the missed calls notification. */ void cancelMissedCallsNotification(); /** * Supply a pin to unlock the SIM.Blocks until a result is determined. * @param pin The pin to check. * @return whether the operation was a success. */ boolean supplyPin(String pin); /** * Handles PIN MMI commands (PIN/PIN2/PUK/PUK2), which are initiated * without SEND (so < code> dial< /code> is not appropriate). * * @param dialString the MMI command to be executed. * @return true if MMI command is executed. */ boolean handlePinMmi(String dialString); /** * Toggles the radio on or off. */ void toggleRadioOnOff(); /** * Set the radio to on or off */ boolean setRadio(boolean turnOn); /** * Request to update location information in service state */ void updateServiceLocation(); /** * Enable location update notifications. */ void enableLocationUpdates(); /** * Disable location update notifications. */ void disableLocationUpdates(); /** * Enable a specific APN type. */ int enableApnType(String type); /** * Disable a specific APN type. */ int disableApnType(String type); /** * Allow mobile data connections. */ boolean enableDataConnectivity(); /** * Disallow mobile data connections. */ boolean disableDataConnectivity(); /** * Report whether data connectivity is possible. */ boolean isDataConnectivityPossible(); Bundle getCellLocation(); /** * Returns the neighboring cell information of the device. */ List< NeighboringCellInfo> getNeighboringCellInfo(); int getCallState(); int getDataActivity(); int getDataState(); }

三、主要实现代码
在Activity中import com.android.internal.telephony.ITelephony; 就可以使用ITelephony接口

package com.example.administrator.locker2; import java.lang.reflect.Method; import android.app.Service; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.os.IBinder; import android.telephony.PhoneStateListener; import android.telephony.TelephonyManager; import android.util.Log; import com.android.internal.telephony.ITelephony; public class PhoneReceiver extends BroadcastReceiver { String TAG = "PhoneReceiver"; @Override public void onReceive(Context context, Intent intent) { if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)) { // 如果是去电（拨出） } else { TelephonyManager tm = (TelephonyManager) context.getSystemService(Service.TELEPHONY_SERVICE); // 设置一个监听器 tm.listen(listener, PhoneStateListener.LISTEN_CALL_STATE); } }PhoneStateListener listener = new PhoneStateListener() {@Override public void onCallStateChanged(int state, String incomingNumber) { // state 当前状态 incomingNumber,貌似没有去电的API super.onCallStateChanged(state, incomingNumber); switch (state) { //手机空闲了 case TelephonyManager.CALL_STATE_IDLE: break; //电话被挂起 case TelephonyManager.CALL_STATE_OFFHOOK: break; // 当电话呼入时 case TelephonyManager.CALL_STATE_RINGING: Log.e(TAG, "来电号码是："+ incomingNumber); // 如果该号码属于黑名单 if (incomingNumber.equals("*********")) { // TODO:如果是黑名单，就进行屏蔽 stopCall(); } break; } } }; public void stopCall() {try { Method method = Class.forName("android.os.ServiceManager").getMethod("getService", String.class); // 获取远程TELEPHONY_SERVICE的IBinder对象的代理 IBinder binder = (IBinder) method.invoke(null, new Object[] { "phone" }); // 将IBinder对象的代理转换为ITelephony对象 ITelephony telephony = ITelephony.Stub.asInterface(binder); // 挂断电话 telephony.endCall(); //telephony.cancelMissedCallsNotification(); } catch (Exception e) { }}}
