我们如何向此集团添加AlertDialog？

Question

我想在收到电话时添加一个AlertDialog（SIP应用程序），我真的很困惑如何在这个集团中添加它：

public class IncomingCallReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        SipAudioCall incomingCall = null;
        try {

            SipAudioCall.Listener listener = new SipAudioCall.Listener() {
                @Override
                public void onRinging(SipAudioCall call, SipProfile caller) {
                    try {
                        call.answerCall(30);
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                }
            };

            SIPCommunicator wtActivity = (SIPCommunicator) context;

            incomingCall = wtActivity.manager.takeAudioCall(intent, listener);
            incomingCall.answerCall(30);
            incomingCall.startAudio();
            incomingCall.setSpeakerMode(true);
            if(incomingCall.isMuted()) {
                incomingCall.toggleMute();
            }

            wtActivity.call = incomingCall;

            wtActivity.updateStatus(incomingCall);

        } catch (Exception e) {
            if (incomingCall != null) {
                incomingCall.close();
            }
        }
    }

}

非常感谢你的帮助。

根据文档，你无法在onReceive中找到alertdialog
