Hi, ich habe ein SwipeRefreshLayout, das ein relatives Layout enthält, das eine Bildlaufansicht und eine andere Ansicht enthält, wenn ich in der Liste nach unten scrolle, wird manchmal kein Bildlauf nach oben ausgeführt, stattdessen wird die onRefresh-Funktion ausgeführt. Wie verhindere ich, dass dies ausgeführt wird, es sei denn, die Ansicht befindet sich oben? Ich hatte über canChildScrollUp gelesen, aber keinen Weg gefunden, es richtig zu implementieren.

heres mein Layout

nd hier, wo ich meine Klasse implementiert ha

swipeLayout = (SwipeRefreshLayout)v.findViewById(R.id.swipe_container);
        swipeLayout.setColorSchemeColors(Color.parseColor("#ed037c"), Color.parseColor("#c40053"),Color.parseColor("#ffffff"), Color.parseColor("#51af50"));

        swipeLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() { 
            @Override public void onRefresh() { 
                swipeLayout.setRefreshing(true);
                Log.d("Swipe", "Refreshing Number"); 
                ( new Handler()).postDelayed(new Runnable() { 
                    @Override public void run() { 

                        updateLocalData();

                    } 
                    }, 3000); 
                }
            });
