爲了知道主叫方是否收到了呼叫，您需要創建一個監聽器。與你的活動作爲 phoneInfo = new PhoneInfo(this); registerReceiver(phoneInfo, new IntentFilter(Intent.ACTION_NEW_OUTGOING_CALL));

class PhoneInfo extends BroadcastReceiver { 
/** 
* Getting the System Telephony Service and registering a listener for Voice Call state 
*/ 
@Override 
public void onReceive(Context context, Intent intent) { 
    IncomingCallListener phoneListener = new IncomingCallListener(); 
    TelephonyManager telephony = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE); 
    telephony.listen(phoneListener, PhoneStateListener.LISTEN_CALL_STATE); 
} 

class IncomingCallListener extends PhoneStateListener { 

    public void onCallStateChanged(int state, String incomingNumber) { 
     Log.i(logcat,"CALL_STATE changed " + callflag); 

     switch (state) { 
     case TelephonyManager.CALL_STATE_IDLE: 
      Log.i(logcat,"CALL_STATE_IDLE"); 
            //This is where call ends. 
      break; 

     case TelephonyManager.CALL_STATE_OFFHOOK: 
            //This is where we know call is established 
      break; 

     case TelephonyManager.CALL_STATE_RINGING: 
      Log.i(logcat,"CALL_STATE_RINGING"); 
      break; 
     } 


    } 

}
