Android来电监听和去电监听实现代码

// 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
  }
}

@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;
  }
}

/** 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

// OutgoingCallListener继承一个BroadcastReceiver
<receiver android:name="com.test.OutgoingCallListener" >
  <intent-filter>
    <action android:name="android.intent.action.PHONE_STATE"/>
    <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
  </intent-filter>
</receiver>
