我觉得写文章就得写得有用一些的,必须要有自己的思想,关于来电去电监听将按照下面三个问题展开
1、监听来电去电有什么用?
2、怎么监听,来电去电监听方式一样吗?
3、实战,有什么需要特别注意地方?
一、监听来电去电能干什么
1、能够对监听到的电话做个标识,告诉用户这个电话是诈骗、推销、广告什么的
2、能够针对那些特殊的电话进行自动挂断,避免打扰到用户
二、来电去电的监听方式(不一样的方式)
2.1 来去电监听方式一(PhoneStateListener)
来电监听是使用PhoneStateListener类,使用方式是,将PhoneStateListener对象(一般是自己继承PhoneStateListener类完成一些封装)注册到系统电话管理服务中去(TelephonyManager)
然后通过PhoneStateListener的回调方法onCallStateChanged(int state, String incomingNumber) 实现来电的监听 (详细实现可以参考后面给出的拓展阅读部分)
注册监听
private void registerPhoneStateListener() {
CustomPhoneStateListener customPhoneStateListener = new CustomPhoneStateListener(this);
TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
if (telephonyManager != null) {
telephonyManager.listen(customPhoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);
}
}
PhoneStateListener的onCallStateChanged方法监听来电状态
package com.phone.listen; import android.content.Context;
import android.telephony.PhoneStateListener;
import android.telephony.ServiceState;
import android.telephony.TelephonyManager;
import android.util.Log; /**
* 来去电监听
*/
public class CustomPhoneStateListener extends PhoneStateListener { private Context mContext; public CustomPhoneStateListener(Context context) {
mContext = context;
} @Override
public void onServiceStateChanged(ServiceState serviceState) {
super.onServiceStateChanged(serviceState);
Log.d(PhoneListenService.TAG, "CustomPhoneStateListener onServiceStateChanged: " + serviceState);
} @Override
public void onCallStateChanged(int state, String incomingNumber) {
Log.d(PhoneListenService.TAG, "CustomPhoneStateListener state: "
+ state + " incomingNumber: " + incomingNumber);
switch (state) {
case TelephonyManager.CALL_STATE_IDLE: // 电话挂断
break;
case TelephonyManager.CALL_STATE_RINGING: // 电话响铃
Log.d(PhoneListenService.TAG, "CustomPhoneStateListener onCallStateChanged endCall");
HangUpTelephonyUtil.endCall(mContext);
break;
case TelephonyManager.CALL_STATE_OFFHOOK: // 来电接通 或者 去电,去电接通 但是没法区分
break;
}
}
}
三种状态源码解释
/** Device call state: No activity. */
public static final int CALL_STATE_IDLE = 0; // 电话挂断
/** Device call state: Ringing. A new call arrived and is
* ringing or waiting. In the latter case, another call is
* already active. */
public static final int CALL_STATE_RINGING = 1; // 来电响铃
/** Device call state: Off-hook. At least one call exists
* that is dialing, active, or on hold, and no calls are ringing
* or waiting. */
public static final int CALL_STATE_OFFHOOK = 2; // 来电接通 或者 去电拨号 但是没法区分出来
2.2 来去电方式二(广播监听)
<receiver android:name=".PhoneStateReceiver"
android:enabled="true"
android:process=":PhoneListenService">
<intent-filter>
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
</receiver>
package com.phone.listen; import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.TelephonyManager;
import android.util.Log; /**
* Created by popfisher on 2017/11/6.
*/ public class PhoneStateReceiver extends BroadcastReceiver { @Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
Log.d(PhoneListenService.TAG, "PhoneStateReceiver action: " + action); String resultData = this.getResultData();
Log.d(PhoneListenService.TAG, "PhoneStateReceiver getResultData: " + resultData); if (action.equals(Intent.ACTION_NEW_OUTGOING_CALL)) {
// 去电,可以用定时挂断
// 双卡的手机可能不走这个Action
String phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
Log.d(PhoneListenService.TAG, "PhoneStateReceiver EXTRA_PHONE_NUMBER: " + phoneNumber);
} else {
// 来电去电都会走
// 获取当前电话状态
String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
Log.d(PhoneListenService.TAG, "PhoneStateReceiver onReceive state: " + state); // 获取电话号码
String extraIncomingNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
Log.d(PhoneListenService.TAG, "PhoneStateReceiver onReceive extraIncomingNumber: " + extraIncomingNumber); if (state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_RINGING)) {
Log.d(PhoneListenService.TAG, "PhoneStateReceiver onReceive endCall");
HangUpTelephonyUtil.endCall(context);
}
}
}
}
三、实战,有什么需要特别注意地方
3.1 双卡双待的手机怎么获取
对于双卡手机,每张卡都对应一个Service和一个PhoneStateListener,需要给每个服务注册自己的PhoneStateListener,服务的名称还会有点变化,厂商可能会修改
public ArrayList<String> getMultSimCardInfo() {
// 获取双卡的信息,这个也是经验尝试出来的,不知道其他厂商有什么坑
ArrayList<String> phoneServerList = new ArrayList<String>();
for(int i = 1; i < 3; i++) {
try {
String phoneServiceName;
if (MiuiUtils.isMiuiV6()) {
phoneServiceName = "phone." + String.valueOf(i-1);
} else {
phoneServiceName = "phone" + String.valueOf(i);
} // 尝试获取服务看是否能获取到
IBinder iBinder = ServiceManager.getService(phoneServiceName);
if(iBinder == null) continue; ITelephony iTelephony = ITelephony.Stub.asInterface(iBinder);
if(iTelephony == null) continue; phoneServerList.add(phoneServiceName);
} catch(Exception e) {
e.printStackTrace();
}
}
// 这个是默认的
phoneServerList.add(Context.TELEPHONY_SERVICE);
return phoneServerList;
}
3.2 挂断电话
挂断电话使用系统服务提供的接口去挂断,但是挂断电话是个并不能保证成功的方法,所以会有多种方式挂断同时使用,下面提供
package com.phone.listen; import android.content.Context;
import android.os.RemoteException;
import android.telephony.TelephonyManager; import com.android.internal.telephony.ITelephony; import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
import java.util.concurrent.Executor;
import java.util.concurrent.Executors; /**
* 封装挂断电话接口
*/
public class HangUpTelephonyUtil {
public static boolean endCall(Context context) {
boolean callSuccess = false;
ITelephony telephonyService = getTelephonyService(context);
try {
if (telephonyService != null) {
callSuccess = telephonyService.endCall();
}
} catch (RemoteException e) {
e.printStackTrace();
} catch (Exception e){
e.printStackTrace();
}
if (callSuccess == false) {
Executor eS = Executors.newSingleThreadExecutor();
eS.execute(new Runnable() {
@Override
public void run() {
disconnectCall();
}
});
callSuccess = true;
}
return callSuccess;
} private static ITelephony getTelephonyService(Context context) {
TelephonyManager telephonyManager = (TelephonyManager)
context.getSystemService(Context.TELEPHONY_SERVICE);
Class clazz;
try {
clazz = Class.forName(telephonyManager.getClass().getName());
Method method = clazz.getDeclaredMethod("getITelephony");
method.setAccessible(true);
return (ITelephony) method.invoke(telephonyManager);
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (NoSuchMethodException e) {
e.printStackTrace();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
}
return null;
} private static boolean disconnectCall() {
Runtime runtime = Runtime.getRuntime();
try {
runtime.exec("service call phone 5 \n");
} catch (Exception exc) {
exc.printStackTrace();
return false;
}
return true;
} // 使用endCall挂断不了,再使用killCall反射调用再挂一次
public static boolean killCall(Context context) {
try {
// Get the boring old TelephonyManager
TelephonyManager telephonyManager = (TelephonyManager)
context.getSystemService(Context.TELEPHONY_SERVICE); // Get the getITelephony() method
Class classTelephony = Class.forName(telephonyManager.getClass().getName());
Method methodGetITelephony = classTelephony.getDeclaredMethod("getITelephony"); // Ignore that the method is supposed to be private
methodGetITelephony.setAccessible(true); // Invoke getITelephony() to get the ITelephony interface
Object telephonyInterface = methodGetITelephony.invoke(telephonyManager); // Get the endCall method from ITelephony
Class telephonyInterfaceClass = Class.forName(telephonyInterface.getClass().getName());
Method methodEndCall = telephonyInterfaceClass.getDeclaredMethod("endCall"); // Invoke endCall()
methodEndCall.invoke(telephonyInterface);
} catch (Exception ex) { // Many things can go wrong with reflection calls
return false;
}
return true;
}
}
ITelephony接口在layoutlib.jar包中,需要导入 android sdk目录\platforms\android-8\data\layoutlib.jar
挂断电话需要权限
<uses-permission android:name="android.permission.CALL_PHONE" />
3.3 监听来去电状态放到后台服务(独立进程)
<service android:name=".PhoneListenService"
android:label="Android来电监听"
android:process=":PhoneListenService"/>
来去电监听Service
package com.phone.listen; import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.os.IBinder;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.util.Log; /**
* 来去电监听服务
*/
public class PhoneListenService extends Service { public static final String TAG = PhoneListenService.class.getSimpleName(); public static final String ACTION_REGISTER_LISTENER = "action_register_listener"; @Override
public void onCreate() {
super.onCreate();
Log.d(TAG, "onCreate");
} @Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.d(TAG, "onStartCommand action: " + intent.getAction() +
" flags: " + flags + " startId: " + startId);
String action = intent.getAction();
if (action.equals(ACTION_REGISTER_LISTENER)) {
registerPhoneStateListener();
}
return super.onStartCommand(intent, flags, startId);
} private void registerPhoneStateListener() {
CustomPhoneStateListener customPhoneStateListener = new CustomPhoneStateListener(this);
TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
if (telephonyManager != null) {
telephonyManager.listen(customPhoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);
}
}
}
3.4 整体配置文件
<?xml version="1.0" encoding="utf-8"?>
