 要监听android打电话和接电话，只需下面2步骤
第一步，写一个Receiver继承自BroadcastReceiver

来电action为TelephonyManager.ACTION_PHONE_STATE_CHANGED

去电action为Intent.ACTION_NEW_OUTGOING_CALL

     public
      
     class
      PhoneStatReceiver 
     extends
      BroadcastReceiver{ 
     private
      
     static
      
     final
      String TAG 
     =
      
     "
     PhoneStatReceiver
     "
     ; 
     //
      private static MyPhoneStateListener phoneListener = new MyPhoneStateListener();
      
      
     private
      
     static
      
     boolean
      incomingFlag 
     =
      
     false
     ; 
     private
      
     static
      String incoming_number 
     =
      
     null
     ; @Override 
     public
      
     void
      onReceive(Context context, Intent intent) { 
     //
     如果是拨打电话
      
      
     if
     (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)){ incomingFlag 
     =
      
     false
     ; String phoneNumber 
     =
      intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER); Log.i(TAG, 
     "
     call OUT:
     "
     +
     phoneNumber); }
     else
     { 
     //
     如果是来电
      
      TelephonyManager tm 
     =
      (TelephonyManager)context.getSystemService(Service.TELEPHONY_SERVICE); 
     switch
      (tm.getCallState()) { 
     case
      TelephonyManager.CALL_STATE_RINGING: incomingFlag 
     =
      
     true
     ;
     //
     标识当前是来电
      
      incoming_number 
     =
      intent.getStringExtra(
     "
     incoming_number
     "
     ); Log.i(TAG, 
     "
     RINGING :
     "
     +
      incoming_number); 
     break
     ; 
     case
      TelephonyManager.CALL_STATE_OFFHOOK: 
     if
     (incomingFlag){ Log.i(TAG, 
     "
     incoming ACCEPT :
     "
     +
      incoming_number); } 
     break
     ; 
     case
      TelephonyManager.CALL_STATE_IDLE: 
     if
     (incomingFlag){ Log.i(TAG, 
     "
     incoming IDLE
     "
     ); } 
     break
     ; } } } }

    

第二步：在AndroidManifest.xml，配置写好的Receiver，并拦截相应的BroadCastAction，
另外注意加上相应的权限。
