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？
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 来电去电的监听方式（不一样的方式） 1、来电监听（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
// phoneServiceName是服务名，一般是 "phone" --> Context.TELEPHONY_SERVICE
TelephonyManager telephonyManager = (TelephonyManager) mContext.getSystemService(phoneServiceName);
if(telephonyManager != null) {
try {
// 注册来电监听
telephonyManager.listen(mTelephonyListener, PhoneStateListener.LISTEN_CALL_STATE);
} catch(Exception e) {
// 异常捕捉
}
}
PhoneStateListener的onCallStateChanged方法监听来电状态
@Override
public void onCallStateChanged(int state, String incomingNumber) {
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
// 电话挂断
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
// 来电响铃
break;
case TelephonyManager.CALL_STATE_RINGING:
// 来电接通
break;
default:
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
2、去电监听（通过广播来实现）
// OutgoingCallListener继承一个BroadcastReceiver
" com.test.OutgoingCallListener" >
"android.intent.action.PHONE_STATE"/>
"android.intent.action.NEW_OUTGOING_CALL" />
实战，有什么需要特别注意地方
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 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 phoneServerList = new ArrayList();
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;
}
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
public boolean endCall() {
boolean callSuccess = false;
ITelephony telephonyService = getTelephonyService();
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 boolean disconnectCall() {
Runtime runtime = Runtime.getRuntime();
try {
runtime.exec("service call phone 5
");
} 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;
}
3、挂断电话需要权限
<uses-permission android:name="android.permission.CALL_PHONE" />
