Android监听来电去电

 class MyPhoneStateListener extends PhoneStateListener {    @Override  public void onCallStateChanged(int state, String incomingNumber) {  switch(state) {  case TelephonyManager.CALL_STATE_IDLE: //空闲  break;  case TelephonyManager.CALL_STATE_RINGING: //来电  break;  case TelephonyManager.CALL_STATE_OFFHOOK: //摘机（正在通话中）  break;  }  }    }      //获取电话通讯服务  TelephonyManager tpm = (TelephonyManager) this  .getSystemService(Context.TELEPHONY_SERVICE);  //创建一个监听对象，监听电话状态改变事件  tpm.listen(new MyPhoneStateListener(),  PhoneStateListener.LISTEN_CALL_STATE);
