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

Mostly this is used by the * TelephonyManager class. A few places are still using this directly. * Please clean them up if possible and use TelephonyManager insteadl. * * {@hide} */ interface ITelephony { /** * Dial a number. 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.

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) {
}
}
}
四、真机测试,当本机开启该应用时,拦截号码拨号方显示您所拨打的电话正在通话中
