如何檢查收到的意向操作是NEW_OUTGOING_CALL，NEW_INCOMING_CALL還是掛斷？

Question

private static final String CALLACTION = "android.intent.action.PHONE_STATE"; 

然後我註冊它

final IntentFilter theCallFilter = new IntentFilter(); 
     theCallFilter.addAction(CALLACTION); 

     yourCallReceiver = new CallReceiver();   

     // Registers the receiver so that your service will listen for broadcasts 
     registerReceiver(yourCallReceiver, theCallFilter); 

，後來我用

if(intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED")) { ... } 

檢查，但我也檢查，如果是

android.intent.action.NEW_OUTGOING_CALL 

或來電，或者是掛向上...？如果是如何PHONE_STATE活動中
