监听手机状态--PhoneStateListener

 

通过向TelephonyManager注册一个listener，就可以监听手机的一些状态的变化。

自定义的监听器：

1. class MyPhoneStateListener extends PhoneStateListener  
2. {  
3.     Context context;  
4.     public MyPhoneStateListener(Context con)  
5.     {  
6.          context = con;  
7.     }  
8.       
9.     public void onCallForwardingIndicatorChanged(boolean cfi)   
10.     {  
11.           
12.     }  
13.       
14.     public void onCallStateChanged(int state, String incomingNumber)   
15.     {  
16.         switch(state)  
17.         {  
18.         case TelephonyManager.CALL_STATE_IDLE:  
19.             Toast.makeText(context, "call not answer", Toast.LENGTH_LONG).show();  
20.             break;  
21.

12.                 PhoneStateListener.LISTEN_SERVICE_STATE |  
13.                 PhoneStateListener.LISTEN_SIGNAL_STRENGTH);  

String srvcName = Context.TELEPHONY_SERVICE; TelephonyManager telephonyManager = (TelephonyManager)getSystemService(srvcName); MyPhoneStateListener phoneStateListener = new MyPhoneStateListener(this); telephonyManager.listen(phoneStateListener, PhoneStateListener.LISTEN_CALL_FORWARDING_INDICATOR | PhoneStateListener.LISTEN_CALL_STATE | PhoneStateListener.LISTEN_CELL_LOCATION | PhoneStateListener.LISTEN_DATA_ACTIVITY | PhoneStateListener.LISTEN_DATA_CONNECTION_STATE | PhoneStateListener.LISTEN_MESSAGE_WAITING_INDICATOR | PhoneStateListener.LISTEN_SERVICE_STATE | PhoneStateListener.LISTEN_SIGNAL_STRENGTH);
