我在firebase例程中有以下代码.收到通知时,如何将通知消息或数据显示为警报？我的服务器上的PHP代码成功地通过id将消息推送到Android设备,并且在收到消息时听到声音,但我想显示警报或转移到片段(我更喜欢警报).

public class MyFirebaseMessagingService extends FirebaseMessagingService
{
    private static final String TAG = "MyFirebaseMessService";

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage)
    {
        commonfunc.myprint("#####_____MyFirebaseMessService_from 1 : " + remoteMessage.getFrom());


        if(remoteMessage.getData().size() > 0)
        {
            commonfunc.myprint("MyFirebaseMessService_getdata 2 : " + remoteMessage.getData());
            Map<String, String> data = remoteMessage.getData();
            String value1 = data.get("dtitle");
            String value2 = data.get("dbody");
            commonfunc.myprint("MyFirebaseMessService_getdata 2 : " + value1 + " " + value2);
            sendNotification(remoteMessage.getData().toString());
        }
        if (remoteMessage.getNotification() != null)
        {
            commonfunc.myprint("MyFirebaseMessService_getNot 3 body: " + remoteMessage.getNotification().getBody());
            commonfunc.myprint("MyFirebaseMessService_getNot 3 title: " + remoteMessage.getNotification().getTitle());

            sendNotification(remoteMessage.getNotification().getBody()); …
