@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;
        }
    }
}

Answer 2

你可以这样做，但这不适用于所有手机。

创建通知侦听器服务，告知其他人接听电话。public class CallNotification extends NotificationListenerService { public void onNotificationPosted(StatusBarNotification sbn) { //your code here after you getting notification another person has pick up the call } }
要求系统发出允许通知。

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