android 电话监听和拦截

Posted 2020-10-14 钱大少丶

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

1 <receiver android:name=".PhoneReceiver">
2             <intent-filter android:priority="1000">
3                 <action android:name="android.intent.action.PHONE_STATE"/>
4                 <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
5             </intent-filter>
6         </receiver>

 1 1 <!-- 添加访问手机电话状态的权限 --> 2 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

三、主要实现代码

在Activity中import com.android.internal.telephony.ITelephony;就可以使用ITelephony接口

 1 package com.example.administrator.locker2;
 2 
 3 import java.lang.reflect.Method;
 4 
 5 import android.app.Service;
 6 import android.content.BroadcastReceiver;
 7 import android.content.Context;
 8 import android.content.Intent;
 9 import android.os.IBinder;
10 import android.telephony.PhoneStateListener;
11 import android.telephony.TelephonyManager;
12 import android.util.Log;
13 
14 import com.android.internal.telephony.ITelephony;
15 
16 public class PhoneReceiver extends BroadcastReceiver {
17     String TAG = "PhoneReceiver";
18 
19     @Override
20     public void onReceive(Context context, Intent intent) {
21         if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)) {
22             // 如果是去电（拨出）
23         } else {
24             TelephonyManager tm = (TelephonyManager) context.getSystemService(Service.TELEPHONY_SERVICE);
25             // 设置一个监听器
26             tm.listen(listener, PhoneStateListener.LISTEN_CALL_STATE);
27         }
28     }
29 
30     PhoneStateListener listener = new PhoneStateListener() {
31 
32         @Override
33         public void onCallStateChanged(int state, String incomingNumber) {
34             // state 当前状态 incomingNumber,貌似没有去电的API
35             super.onCallStateChanged(state, incomingNumber);
36             switch (state) {
37                 //手机空闲了
38                 case TelephonyManager.CALL_STATE_IDLE:
39                     break;
40                 //电话被挂起
41                 case TelephonyManager.CALL_STATE_OFFHOOK:
42                     break;
43                 // 当电话呼入时
44                 case TelephonyManager.CALL_STATE_RINGING:
45                     Log.e(TAG, "来电号码是："+ incomingNumber);
46                     // 如果该号码属于黑名单
47                     if (incomingNumber.equals("*********")) {
48                         // TODO:如果是黑名单，就进行屏蔽
49                         stopCall();
50 　　　　　　　　　　　　　}
51                     break;
52             }
53         }
54     };
55 
56     public void stopCall() {
57 
58         try {
59             Method method = Class.forName("android.os.ServiceManager").getMethod("getService", String.class);
60             // 获取远程TELEPHONY_SERVICE的IBinder对象的代理
61             IBinder binder = (IBinder) method.invoke(null, new Object[] { "phone" });
62             // 将IBinder对象的代理转换为ITelephony对象
63             ITelephony telephony = ITelephony.Stub.asInterface(binder);
64             // 挂断电话
65             telephony.endCall();
66             //telephony.cancelMissedCallsNotification();
67 
68         } catch (Exception e) {
69         }
70 
71     }
72 
73 }

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
