@Override 
public void onReceive(Context context, Intent intent) { 
    Log.d("Intent", intent.toString()); 
    if(intent.getAction().equals("android.intent.action.NEW_OUTGOING_CALL")) 
    { 
     Log.e("Call_state","outgoing call detected"); 
    } 

//  Checking for the call status 
    try { 
     // TELEPHONY MANAGER class object to register one listner 
     TelephonyManager tmgr = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE); 
     //Create Listner 
     MyPhoneStateListener PhoneListener = new MyPhoneStateListener(); 
     // Register listener for LISTEN_CALL_STATE 
     tmgr.listen(PhoneListener, PhoneStateListener.LISTEN_CALL_STATE); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
} 

private class MyPhoneStateListener extends PhoneStateListener { 
    public void onCallStateChanged(int state, String incomingNumber) { 
     switch (state) { 
      case TelephonyManager.CALL_STATE_RINGING: 
       Log.e("Call_state","call ringing"); 
       break; 
      case TelephonyManager.CALL_STATE_OFFHOOK: 
       Log.e("Call_state","call offhook"); 
       break; 
      case TelephonyManager.CALL_STATE_IDLE: 
       Log.e("Call_state","call idle"); 
       break; 
     } 
    } 
}

你可以這樣做，但是這將不是所有手機上運行。

1. 創建通知監聽器服務，告訴你另一個人接聽電話。 public class CallNotification extends NotificationListenerService { public void onNotificationPosted(StatusBarNotification sbn) { //your code here after you getting notification another person has pick up the call } }

2. 詢問系統允許通知。

   Intent intent = new Intent("android.settings.ACTION_NOTIFICATION_LISTENER_SETTINGS"); startActivity(intent);
