本文介绍如何使用TelephonyManager注册PhoneStateListener以监听指定的电话状态变更。通过传递PhoneStateListener实例并设置感兴趣的电话状态事件，当这些状态发生改变时，TelephonyManager会调用监听器对象上的相应回调方法，并传递最新的状态值。

* Registers a listener object to receive notification of changes
* in specified telephony states.
* To register a listener, pass a {@link PhoneStateListener}
* and specify at least one telephony state of interest in
* the events argument.
* At registration, and when a specified telephony state
* changes, the telephony manager invokes the appropriate
* callback method on the listener object and passes the
* current (udpated) values.
* To unregister a listener, pass the listener object and set the
* events argument to {@link PhoneStateListener#LISTEN_NONE LISTEN_NONE} (0)


telManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
				psListener = new PhoneStatusListener();
				telManager.listen(psListener, PhoneStateListener.LISTEN_CALL_STATE);　　//监听
telManager.listen(psListener, PhoneStateListener.LISTEN_NONE);　　//取消监听
